Symptoms of polyps include nasal congestion, sinusitis, loss of smell, thick nasal discharge, facial pressure, nasal speech, and mouth breathing. Recurrent sinusitis can result from polyps. Long-term, nasal polyps can cause destruction of the nasal bones and widening of the nose.

As polyps grow larger, they eventually prolapse into the nasal cavity resulting in symptoms. The most prominent symptoms of nasal polyps result blockage of the nasal passage.

People with nasal polyps due to aspirin intolerance often have symptoms known as Samter's triad, which consists of asthma worse with aspirin, a skin rash caused by aspirin, and chronic nasal polyps.

Nasal polyps (NP) are noncancerous growths within the nose or sinuses. Symptoms include trouble breathing through the nose, loss of smell, decreased taste, post nasal drip, and a runny nose. The growths are sac-like, movable, and nontender, though face pain may occasionally occur. They typically occur in both nostrils in those who are affected. Complications may include sinusitis and broadening of the nose.

The exact cause is unclear. They may be related to chronic inflammation of the lining of the sinuses. They occur more commonly among people who have allergies, cystic fibrosis, aspirin sensitivity, or certain infections. The polyp itself represents an overgrowth of the mucous membranes. Diagnosis may occur by looking up the nose. A CT scan may be used to determine the number of polyps and help plan surgery.

Treatment is typically with steroids, often in the form of a nasal spray. If this is not effective surgery may be considered. The condition often recurs following surgery, thus continued use of a steroid nasal sprays is often recommended. Antihistamines may help with symptoms but do not change the underlying disease. Antibiotics are not required for treatment unless an infection occurs.

About 4% of people currently have nasal polyps while up to 40% of people develop them at some point in their life. They most often occur after the age of 20 and are more frequent in males than females. Nasal polyps have been described since at least the time of the Ancient Egyptians.

A cervical polyp is a common benign polyp or tumor on the surface of the cervical canal. They can cause irregular menstrual bleeding or increased pain but often show no symptoms.

Nasal polyps are polypoidal masses arising mainly from the mucous membranes of the nose and paranasal sinuses. They are overgrowths of the mucosa that frequently accompany allergic rhinitis. They are freely movable and nontender.

Most polyps do not cause noticeable symptoms. Gallbladder polyps are usually found incidentally when examining the abdomen by ultrasound for other conditions, usually abdominal pain.

The most common general classification is:

- hyperplastic,

- neoplastic (adenomatous & malignant),

- hamartomatous and,

- inflammatory.

Colorectal polyps are not usually associated with symptoms. When they occur, symptoms include rectal bleeding, bloody stools, abdominal pain and fatigue. A change in bowel habits may occur including constipation and diarrhoea. Occasionally, if a polyp is big enough to cause a bowel obstruction, there may be nausea, vomiting and severe constipation.

In most cases, symptoms present themselves at an advanced stage of disease. They can include but are not limited to:

Nosebleed

Nasal obstruction

Proptosis (displacement of the eye)

Vision changes

Headache

Gallbladder polyps are growths or lesions resembling growths (polypoid lesions) in the wall of the gallbladder. True polyps are abnormal accumulations of mucous membrane tissue that would normally be shed by the body. The main types of polypoid growths of the gallbladder include cholesterol polyp/cholesterosis, cholesterosis with fibrous dysplasia of gallbladder, adenomyomatosis, hyperplastic cholecystosis, and adenocarcinoma.

Rhinoliths present as unilateral nasal obstruction. Foul-smelling, blood-stained discharge is often present. Epistaxis and pain may occur due to the ulceration of surrounding mucosa.

Age of onset is variable. The term 'Juvenile' in the title of Juvenile polyposis syndrome refers to the histological type of the polyps rather than age of onset.

Affected individuals may present with rectal bleeding, abdominal pain, diarrhea or anemia. On colonoscopy or sigmoidoscopy polyps that vary in shape or size are present. The polyps can be sessile or pedunculated hamartomatous polyps.

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

Juvenile polyposis syndrome is a syndrome characterized by the appearance of multiple juvenile polyps in the gastrointestinal tract. Polyps are abnormal growths arising from a mucous membrane. These usually begin appearing before age 20, but the term "juvenile" refers to the type of polyp, not to the age of the affected person. While the majority of the polyps found in Juvenile Polyposis Syndrome are non-neoplastic, hamartomatous, self-limiting and benign, there is an increased risk of adenocarcinoma.

Solitary juvenile polyps most commonly occur in the rectum and present with rectal bleeding. The World Health Organization criteria for diagnosis of juvenile polyposis syndrome are one of either:

1. More than five juvenile polyps in the colon or rectum; or

2. Juvenile polyps throughout the gastrointestinal tract; or

3. Any number of juvenile polyps in a person with a family history of juvenile polyposis.

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

If nasopharyngeal angiofibroma is suspected based on physical examination (a smooth vascular submucosal mass in the posterior nasal cavity of an adolescent male), imaging studies such as CT or MRI should be performed. Biopsy should be avoided as to avoid extensive bleeding since the tumor is composed of blood vessels without a muscular coat.

Antral sign or Holman-Miller sign (forward bowing of posterior wall of maxilla) is pathognomic of angiofibroma.

Nasopharyngeal angiofibroma (also called juvenile nasopharyngeal angiofibroma) is a histologically benign but locally aggressive vascular tumor that grows in the back of the nasal cavity. It most commonly affects adolescent males. Patients with nasopharyngeal angiofibroma usually present with one-sided nasal obstruction and recurrent bleeding.

A rhinolith is a calculus present in the nasal cavity. The word is derived from the roots "" and "", literally meaning "nose stone". It is an uncommon medical phenomenon, not to be confused with dried nasal mucus. A rhinolith usually forms around the nucleus of a small exogenous foreign body, blood clot or secretion by slow deposition of calcium and magnesium salts. Over a period of time, they grow into large irregular masses that fill the nasal cavity. They may cause pressure necrosis of the nasal septum or lateral wall of nose. Rhinoliths can cause nasal obstruction, epistaxis, headache, sinusitis and epiphora. They can be diagnosed from the history with unilateral foul smelling blood stained nasal discharge or by anterior rhinoscopy. On probing probe can be passed around all its corners. In both CT and MRI rhinolith will appear like a radiopaque irregular material. Small rhinoliths can be removed by foreign body hook. Whereas large rhinoliths can be removed either by crushing with luc's forceps or by Moore's lateral rhinotomy approach.

Sinonasal undifferentiated carcinoma, abbreviated SNUC, is a rare aggressive type of cancer that arises from epithelium or lining of the nose or sinuses.

In the initial phase of the disease, the mucosa feels leathery with palpable fibrotic bands. In the advanced stage the oral mucosa loses its resiliency and becomes blanched and stiff. The disease is believed to begin in the posterior part of the oral cavity and gradually spread outward.

Other features of the disease include:

- Xerostomia

- Recurrent ulceration

- Pain in the ear or deafness

- Nasal intonation of voice

- Restriction of the movement of the soft palate

- A budlike shrunken uvula

- Thinning and stiffening of the lips

- Pigmentation of the oral mucosa

- Dryness of the mouth and burning sensation

- Decreased mouth opening and tongue protrusion

SSAs, generally, are asymptomatic. They are typically identified on a colonoscopy and excised for a definitive diagnosis and treatment.

Cholesteatoma is a destructive and expanding growth consisting of keratinizing squamous epithelium in the middle ear and/or mastoid process. Although cholesteatomas are not classified as either tumors or cancers, they can still cause significant problems because of their erosive and expansile properties resulting in the destruction of the bones of the middle ear (ossicles), as well as their possible spread through the base of the skull into the brain. They are also often infected and can result in chronically draining ears.

The majority (98%) of patients with cholesteatoma have ear discharge or hearing loss or both in the affected ear.

Other more common conditions, such as otitis externa, may also present with these symptoms, but cholesteatoma is much more serious and should not be overlooked. If a patient presents to a doctor with ear discharge and hearing loss, the doctor should consider the patient to have cholesteatoma until the disease is definitely excluded.

Other less common symptoms (all less than 15%) of cholesteatoma may include: pain, balance disruption, tinnitus, ear ache, headaches and bleeding from the ear. There can also be facial nerve weakness.

Balance symptoms in the presence of a cholesteatoma raises the possibility that the cholesteatoma is eroding the balance organs, which form part of the inner ear.

On initial inspection, an ear canal full of discharge may be all that is visible. Until the doctor has cleaned the ear and inspected the entire tympanic membrane, cholesteatoma cannot be either confirmed or excluded.

Once the debris is cleared, cholesteatoma can give rise to a number of appearances. If there is significant inflammation, the tympanic membrane may be partially obscured by an aural polyp. If there is less inflammation, the cholesteatoma may present the appearance of 'semolina' discharging from a defect in the tympanic membrane. The posterior and superior parts of the tympanic membrane are most commonly affected. If the cholesteatoma has been dry, the cholesteatoma may present the appearance of 'wax over the attic'. The attic is just above the ear drum.

The patient may commonly also have clinical signs of conductive hearing loss. Less frequently, there may be signs of imbalance or facial weakness.

If untreated, a cholesteatoma can eat into the three small bones located in the middle ear (the malleus, incus and stapes, collectively called ossicles), which can result in nerve deterioration, deafness, imbalance and vertigo. It can also affect and erode, through the enzymes it produces, the thin bone structure that isolates the top of the ear from the brain, as well as lay the covering of the brain open to infection with serious complications (rarely even death due to brain abscess and septicemia).

Both the acquired as well as the congenital types of the disease can affect the facial nerve that extends from the brain to the face and passes through the inner and middle ear and leaves at the anterior tip of the mastoid bone, and then rises to the front of the ear and extends into the upper and lower face.

SSAs are diagnosed by their microscopic appearance; histomorphologically, they are characterized by (1) basal dilation of the crypts, (2) basal crypt serration, (3) crypts that run horizontal to the basement membrane (horizontal crypts), and (4) crypt branching. The most common of these features is basal dilation of the crypts.

Unlike traditional colonic adenomas (e.g. tubular adenoma, villous adenoma), they do not (typically) have nuclear changes (nuclear hyperchromatism, nuclear crowding, elliptical/cigar-shaped nuclei).

Inflammatory fibroid polyp, abbreviated IFP, is a benign abnormal growth of tissue projecting into the lumen of the gastrointestinal tract.

Villous adenoma is a type of polyp that grows in the colon and other places in the gastrointestinal tract and sometimes in other parts of the body. These adenomas may become malignant (cancerous). Villous adenomas have been demonstrated to contain malignant portions in about one third of affected persons, and invasive malignancy in another one third of removed specimens. Colonic resection may be required for large lesions. These can also lead to secretory diarrhea with large volume liquid stools with few formed elements. They are commonly described as secreting large amounts of mucus, resulting in hypokalaemia in patients. On endoscopy a "cauliflower' like mass is described due to villi stretching. Being an adenoma, the mass is covered in columnar epithelial cells.
