An integral symptom of acute otitis media is ear pain; other possible symptoms include fever, and irritability (in infants). Since an episode of otitis media is usually precipitated by an upper respiratory tract infection (URTI), there are often accompanying symptoms like a cough and nasal discharge.

Discharge from the ear can be caused by acute otitis media with perforation of the ear drum, chronic suppurative otitis media, tympanostomy tube otorrhea, or acute otitis externa. Trauma, such as a basilar skull fracture, can also lead to discharge from the ear due to cerebral spinal drainage from the brain and its covering (meninges).

The most common bacteria isolated from the middle ear in AOM are "Streptococcus pneumoniae, Haemophilus influenzae", "Moraxella catarrhalis," and "Staphylococcus aureus".

Granular myringitis (GM) is a long term condition in which there is inflammation of the tympanic membrane in the ear and formation of granulation tissue within the tympanic membrane. It is a type of otitis externa.

Without treatment it can lead to narrowing of the ear canal. A number of treatment options exist including putting vinegar in the ear, using antibiotic drops, and surgery.

Ear pain can be caused by disease in the external or middle ear(because of infection), or inner ear, but the three are indistinguishable in terms of the pain experienced.

External ear pain may be:

- Mechanical: trauma, foreign bodies such as hairs, insects or cotton buds.

- Infective (otitis externa): "Staphylococcus", "Pseudomonas", "Candida", herpes zoster, or viral Myringitis. (See Otitis externa)

Middle ear pain may be:

- Mechanical: barotrauma (often iatrogenic), Eustachian tube obstruction leading to acute otitis media.

- Inflammatory / infective: acute otitis media, mastoiditis.

Ear pain, also known as otalgia , is pain in the ear. Primary ear pain is pain that originates inside the ear. Referred ear pain is pain that originates from outside the ear.

Ear pain is not always associated with ear disease. It may be caused by several other conditions, such as impacted teeth, sinus disease, inflamed tonsils, infections in the nose and pharynx, throat cancer, and occasionally as a sensory aura that precedes a migraine.

Patients usually present with otorrhea, conductive hearing loss, and otalgia, while bleeding and a sensation of a mass are much less common.

Although imaging is not required to yield a diagnosis, it may be obtained to exclude other disorders, such as a concurrent cholesteatoma.

Signs and symptoms may include:

- Persistent or recurrent enlargement of the lips, causing them to protrude. If recurrent, the interval during which the lips are enlarged may be weeks or months. The enlargement can cause midline fissuring of the lip ("median cheilitis") or angular cheilitis (sores at the corner of the mouth). The swelling is non-pitting (c.f. pitting edema) and feels soft or rubbery on palpation. The mucous membrane of the lip may be erythemaous (red) and granular. One or both lips may be affected.

- Oral ulceration (mouth ulcers) which may be aphthous like, or be more chronic and deep with raised margins. Alternatively, lesions similar to pyostomatitis vegetans may occur in OFG, but this is uncommon.

- "Full width" gingivitis (compare with marginal gingivitis).

- Gingival enlargement (swelling of the gums).

- Fissured tongue (grooves in the tongue).

- Enlargement of the mucous membrane of the mouth, which may be associated with cobblestoning and mucosal tags (similar lesions often occur on the intestinal mucosa in Crohn's disease).

- Enlargement of the perioral and periorbital soft tissues (the tissues of the face around the mouth and the eyes). The facial skin may be dry, exfoliative (flaking) or erythematous.

- Cervical lymphadenopathy (enlarged lymph nodes in the neck).

- Facial palsy (weakness and altered sensation of the face).

The enlargement of the tissues of the mouth, lips and face seen in OFG is painless. Melkersson-Rosenthal syndrome is where OFG occurs with fissured tongue and paralysis of the facial nerve. The cause of the facial paralysis is thought to be caused by the formation of granulomas in the facial nerve, which supplies the muscles of facial expression.

OFG could be classified as a type of cheilitis (lip inflammation), hence the alternative names for the condition using the word cheilitis, and a granulomatous condition.

Most branchial cleft cysts present as a smooth, slowly enlarging lateral neck mass that may increase in size after an upper respiratory tract infection. The fistulas, when present, are asymptomatic, but may become infected.

Patients mostly present with a hard lump in one breast without any sign of a systemic disease. Other possible symptoms include nipple retraction, pain, inflammation of the overlying skin, nipple discharge, fistula, enlarged lymph nodes, in rare case peau d'orange-like changes.

Presentation is mostly unilateral although a significant share of cases is bilateral, also in many cases contralateral or bilateral recurrences were documented.

Several cases occurring together with fever, polyarthralgia and erythema nodosum were documented.

Characteristic for idiopathic granulomatous mastitis are multinucleated giant cells and epithelioid histiocytes forming non-caseating granulomas around lobules. Often minor ductal and periductal inflammation is present. The lesion is in some cases very difficult to distinguish from breast cancer and other causes such as infections (tuberculosis, syphilis, corynebacterial infection, mycotic infection), autoimmune diseases (sarcoidosis, granulomatosis with polyangiitis), foreign body reaction and granulomatous reaction in a carcinoma must be excluded.

The condition is diagnosed very rarely. As the diagnosis is a lengthy differential diagnosis of exclusion there is considerable uncertainty about incidence. It has been suspected that some cases diagnosed as IGM in developing countries may have other explanations. On the other hand, IGM is usually diagnosed only after complications and referral to a secondary breast care center so light cases may resolve spontaneously or after symptomatic treatment and thus never be diagnosed as IGM. As a completely pathogen free breast will be exceedingly rare even in completely healthy population there is also uncertainty when to consider pathogens as causative or as mere coincidental finding.

Granulomatous mastitis can be divided into idiopathic granulomatous mastitis (also known as granular lobular mastitis) and granulomatous mastitis occurring as a rare secondary complication of a great variety of other conditions such as tuberculosis and other infections, sarcoidosis and granulomatosis with polyangiitis. Special forms of granulomatous mastitis occur as complication of diabetes. Some cases are due to silicone injection (Silicone-induced granulomatous inflammation) or other foreign body reactions.

Primary presentation of any of these conditions as mastitis is very rare and in many cases probably predisposed by other breast or systemic conditions.

Although granulomatous mastitis is easily confused with cancer it is a completely benign (non-cancerous) condition.

Treatment is radically different for idiopathic granulomatous mastitis and other granulomatous lesions of the breast, the precise diagnosis is therefore very important.

The most common location by far is the gingival margin and other areas of the masticatory oral mucosa, these occur more frequently in the fifth decade of life, and have good prognosis, the treatment of choice for oral VXs is surgical excision, and recurrence is rare.

The condition can affect other organs of body, such as the penis, vulva, and can occur in anal region, nose, the ear, lower extremity, scrotum.

This type of epulis is neither pyogenic ("pus producing") nor a true granuloma, but it is a vascular lesion. About 75% of all pyogenic granulomas occur on the gingiva, although they may also occur elsewhere in the mouth or other parts of the body (where the term epulis is inappropriate). This common oral lesion is thought to be a reaction to irritation of the tissues and poor oral hygiene. It is more common in younger people and in females, and appears as a red-purple swelling and bleeds easily.

This is a fibrous hyperplasia of excess connective tissue folds that takes place in reaction to chronic trauma from an ill fitting denture. It usually occurs in the mandibular labial sulcus. Sometimes the term "epulis" is used synonymously with epulis fissuratum, but this is technically incorrect as several other lesions could be described as epulides.

Pleural effusion usually occurs in patients previously diagnosed with rheumatoid arthritis, but it can also occur concurrently with or before the development of the joint manifestations of the disease (Graham, 1990; Chou and Chang, 2002). Patients may present with the signs of pleural effusion: dullness on percussion, diminished or absent breath sounds and vocal fremitus, and egophony at the level of the pleural liquid.

A branchial cleft cyst is a cyst in the skin of the lateral part of the neck. It can but does not necessarily have an opening to the skin surface called a fistula. The cause is usually a developmental abnormality arising in the early prenatal period, typically failure of obliteration of the second branchial cleft, i.e. failure of fusion of the second and third branchial arches. Less commonly, the cysts can develop from the first, third, or fourth clefts, and their location and the location of associated fistulas differs accordingly.

Ceruminous adenoma are rare tumors, accounting for less than 1% of all external ear tumors. The patients will present with a mass, perhaps associated pain, and may have changes in hearing (usually a sensorineural or a conductive hearing loss). Some patients have tinnitus. Nerve paralysis is very uncommon.

Verruciform xanthoma is an uncommon benign lesion that has a verruciform (wart-like) appearance, but it may appear polypoid, papillomatous, or sessile. The verruciform was first described by Shafer in 1971 on the oral mucosa. Usually found on the oral mucosa of middle-aged persons, verruciform xanthomas have also been reported on the scrotum and penis of middle-aged to elderly Japanese males. While the most common site is the oral mucosa, lesions that occur elsewhere usually arise on the perineum or on the skin with some predisposing factor, such as lymphedema or an epidermal nevus.

STK typically occurs in the buccal sulcus (inside the cheek) or the labial sulcus (between the lips and the teeth) and corresponds to the site where the tobacco is held in the mouth. It is painless.

The appearance of the lesion is variable depending upon the type of tobacco used, and the frequency and duration of use. It takes about 1-5 years of smokeless tobacco use for the lesion to appear. Early lesions may appear as thin, translucent and granular or wrinkled mucosa. The later lesion may appear thicker, more opaquely white and hyperkeratotic with fissures and folds. Oral snuff causes more pronounced changes in the oral mucosa than tobacco chewing. Snuff dipping is associated more with verrucous keratosis.

As well as the white changes of the oral mucosa, there may be gingival recession (receding gums) and staining of tooth roots in the area where the tobacco is held.

Light microscopy reveals replacement of normal cells lining the pleura (mesothelial cells) by a layer of pseudostratified epithelioid cells, multinucleated giant macrophages, and necrotic material (Mandl et al., 1969; Lillington et al. 1971)

Congenital epulis is a proliferation of cells most frequently occurring on the alveolar ridge of the upper jaw at birth. Less frequently the mass may arise from the mandibular alveolus. Rare cases can arise from the tongue. This lesion is more commonly found in female babies, suggesting hormonal involvement during embryonic development. The cause of this type of epulis is unknown. Also known as congenital granular cell tumor or Neumann's tumor; historically referred to as granular cell myoblastoma.

Multiple lesions occur in 10% of affected neonates. The tumor is typically pedunculated and varies in maximum size from 0.5 cm to 9 cm. The lesion is typically painless and does not increase in size after discovery. Some small lesions may regress over time. Treatment is surgical excision. Recurrence is extremely rare even after incomplete excision.

Many conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square meters, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying mesoderm that forms the dermis and subcutaneous tissues.

The epidermis is the most superficial layer of skin, a squamous epithelium with several strata: the stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale. Nourishment is provided to these layers by diffusion from the dermis, since the epidermis is without direct blood supply. The epidermis contains four cell types: keratinocytes, melanocytes, Langerhans cells, and Merkel cells. Of these, keratinocytes are the major component, constituting roughly 95 percent of the epidermis. This stratified squamous epithelium is maintained by cell division within the stratum basale, in which differentiating cells slowly displace outwards through the stratum spinosum to the stratum corneum, where cells are continually shed from the surface. In normal skin, the rate of production equals the rate of loss; about two weeks are needed for a cell to migrate from the basal cell layer to the top of the granular cell layer, and an additional two weeks to cross the stratum corneum.

The dermis is the layer of skin between the epidermis and subcutaneous tissue, and comprises two sections, the papillary dermis and the reticular dermis. The superficial papillary dermis with the overlying rete ridges of the epidermis, between which the two layers interact through the basement membrane zone. Structural components of the dermis are collagen, elastic fibers, and ground substance. Within these components are the pilosebaceous units, arrector pili muscles, and the eccrine and apocrine glands. The dermis contains two vascular networks that run parallel to the skin surface—one superficial and one deep plexus—which are connected by vertical communicating vessels. The function of blood vessels within the dermis is fourfold: to supply nutrition, to regulate temperature, to modulate inflammation, and to participate in wound healing.

The subcutaneous tissue is a layer of fat between the dermis and underlying fascia. This tissue may be further divided into two components, the actual fatty layer, or panniculus adiposus, and a deeper vestigial layer of muscle, the panniculus carnosus. The main cellular component of this tissue is the adipocyte, or fat cell. The structure of this tissue is composed of septal (i.e. linear strands) and lobular compartments, which differ in microscopic appearance. Functionally, the subcutaneous fat insulates the body, absorbs trauma, and serves as a reserve energy source.

Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails). While only a small number of skin diseases account for most visits to the physician, thousands of skin conditions have been described. Classification of these conditions often presents many nosological challenges, since underlying etiologies and pathogenetics are often not known. Therefore, most current textbooks present a classification based on location (for example, conditions of the mucous membrane), morphology (chronic blistering conditions), etiology (skin conditions resulting from physical factors), and so on. Clinically, the diagnosis of any particular skin condition is made by gathering pertinent information regarding the presenting skin lesion(s), including the location (such as arms, head, legs), symptoms (pruritus, pain), duration (acute or chronic), arrangement (solitary, generalized, annular, linear), morphology (macules, papules, vesicles), and color (red, blue, brown, black, white, yellow). Diagnosis of many conditions often also requires a skin biopsy which yields histologic information that can be correlated with the clinical presentation and any laboratory data.

Parakeratosis is a mode of keratinization characterized by the retention of nuclei in the stratum corneum. In mucous membranes, parakeratosis is normal. In the skin, this process leads to the abnormal replacement of annular squames with nucleated cells. Parakeratosis is associated with the thinning or loss of the granular layer and is usually seen in diseases of increased cell turnover, whether inflammatory or neoplastic. Parakeratosis is seen in the plaques of psoriasis and in dandruff.

Granular parakeratosis (originally termed axillary granular parakeratosis) is an idiopathic, benign, nondisabling cutaneous disease that manifests with intertriginous erythematous, brown or red, scaly or keratotic papules and plaques. It presents in all age groups and has no established clinical associations.

A ceruminous adenoma (also known as adenoma of the ceruminous gland and ceruminoma) is a benign glandular neoplasm which arises from the ceruminous glands located within the external auditory canal. These glands are found within the outer one third to one half of the external auditory canal, more common along the posterior surface; therefore, the tumor develops within a very specific location.
