Diagnosis is clinical, based on observation. Biopsy is rarely required.

In the earlier stages of actinic elastosis, elastic fiber proliferation can be seen in the dermis. As the condition becomes more established, the collagen fibers of the papillary dermis and reticular dermis become increasingly replaced by thickened and curled fibers that form tangled masses and appear basophilic under routine haematoxylin and eosin staining. These fibers stain black with the Verhoeff stain.

The incidence of the disease is higher in people from certain parts of the world including South-East Asia, South Africa and the Middle East.

This disease is caused by problems in the circulatory system, so when it is presented, in the beginning it is important to follow several recommendations. The person needs to keep the legs elevated as much as possible to help the return of the blood. Whenever sitting down, the person needs to keep the legs on a foot stool. At night it is advisable to sleep with a pillow under the lower legs. In the evening, t is not unusual for legs to be swollen. The volume of the lower leg can increase to up to 100ml after a long working day or up to 200ml after a long-haul flight without moving.

In the example of the 41-year-old Japanese man the lesions were much improved by washing and topical use of corticosteroids for two months, also oral antibiotics like cephalexin are used if cellulitis is present. Moist exudative inflammation and moist ulcers respond to tepid wet compresses of Burow’s solution or just saline or water for 30 to 60 minutes several times a day. But in worse cases, edema that does not disappear spontaneously within a few hours or after a walk, is described as pathological, so it needs to have a special treatment. It is very important to say that Papillamitosis, bilateral and marked edema with few symptoms is mostly caused by the systemic circulation (heart, kidneys, liver).

Papillamitosis is associated, as has been mentioned before, with symptoms and/or clinical signs such as dilated superficial veins, varicose veins and changes in the skin. Edema and its complication Papillamitosis are only partially reversible and soon becomes hard, which is mainly confirmed on palpation. All skin structures are affected and this is characterized by the term. Lymphoedema may develop in many cases accompanied by acral thickening of the skin folds, hyperkeratosis and papillomatosis.

Numerous treatment options are available for photoaged skin, including dermabrasion, topical application of retinoic acid, carbon dioxide laser resurfacing, hyaluronic acid injection into the dermis, imiquimod, tacrolimus ointment, and topical oestrogen therapy. These treatments have variable efficacy.

The most effective prevention strategy for photoaging remains minimization of sun exposure, through use of sunscreen and other sun exposure avoidance measures.

Hydroquinone-induced exogenous ochronosis is an avoidable dermatosis that is exceedingly difficult to treat.

However, some studies show that treatment may be possible with a Q-switched alexandrite (755 nm) laser.

It is recommended that individuals with this disorder stop using hydroquinone-containing compounds. It is important to be aware of this as dermatologists may think the symptoms a patient is exhibiting are a melasma, and prescribe a hydroquinone-containing cream.

Nevi are typically diagnosed clinically with the naked eye or using dermatoscopy. More advanced imaging tests are available for distinguishing melanocytic nevi from melanoma, including computerized dermoscopy and image analysis. The management of nevi depends on the type of nevus and the degree of diagnostic uncertainty. Some nevi are known to be benign, and may simply be monitored over time. Others may warrant more thorough examination and biopsy for histopathological examination (looking at a sample of skin under a microscope to detect unique cellular features). For example, a clinician may want to determine whether a pigmented nevus is a type of melanocytic nevus, dysplastic nevus, or melanoma as some of these skin lesions pose a risk for malignancy. The ABCDE criteria (asymmetry, border irregularity, color variegation, diameter > 6 mm, and evolution) are often used to distinguish nevi from melanomas in adults, while modified criteria (amelanosis, bleeding or bumps, uniform color, small diameter or de novo, and evolution) can be used when evaluating suspicious lesions in children. In addition to histopathological examination, some lesions may also warrant additional tests to aid in diagnosis, including special stains, immunohistochemistry, and electron microscopy. Typically; the nevi which exist since childhood are harmless

Treatment is predominantly preventive. Avoidance of topical phenols and diets low in tyrosine may help. Replacement and repair of damaged tissue is also possible.

Recently scientists have proven that intralesional injection of autologous bone marrow stem cells is a safe and effective treatment modality in oral sub mucosal fibrosis. It has been shown autologous bone marrow stem cell injections induces angiogenesis in the area of lesion which in turn decreases the extent of fibrosis thereby leading to significant increase in mouth opening.

Urbach–Wiethe disease is typically diagnosed by its clinical dermatological manifestations, particularly the beaded papules on the eyelids. Doctors can also test the hyaline material with a periodic acid-Schiff (PAS) staining, as the material colors strongly for this stain.

Immunohistochemical skin labeling for antibodies for the ECM1 protein as labeling has been shown to be reduced in the skin of those affected by Urbach–Wiethe disease. Staining with anti-type IV collagen antibodies or anti-type VII collagen antibodies reveals bright, thick bands at the dermoepidermal junction.

Non-contrast CT scans can image calcifications, but this is not typically used as a means of diagnosing the disease. This is partly due to the fact that not all Urbach-Wiethe patients exhibit calcifications, but also because similar lesions can be formed from other diseases such as herpes simplex and encephalitis. The discovery of mutations within the ECM1 gene has allowed the use of genetic testing to confirm initial clinical diagnoses of Urbach–Wiethe disease. It also allows doctors to better distinguish between Urbach–Wiethe disease and other similar diseases not caused by mutations in ECM1.

The management of lipodermatosclerosis may include treating venous insufficiency with leg elevation and elastic compression stockings; in some difficult cases, the condition may be improved with the additional use of the fibrinolytic agent, stanozol. Fibrinolytic agents use an enzymatic action to help dissolve blood clots.

Stanozol is injected directly into the affected area, Venous Ablation has also been known to help circulation in patients.

The management of a nevus depends on the specific diagnosis, however, the options for treatment generally include the following modalities:

The physical examination of the skin and its appendages, as well as the mucous membranes, forms the cornerstone of an accurate diagnosis of cutaneous conditions. Most of these conditions present with cutaneous surface changes termed "lesions," which have more or less distinct characteristics. Often proper examination will lead the physician to obtain appropriate historical information and/or laboratory tests that are able to confirm the diagnosis. Upon examination, the important clinical observations are the (1) morphology, (2) configuration, and (3) distribution of the lesion(s). With regard to morphology, the initial lesion that characterizes a condition is known as the "primary lesion," and identification of such a lesions is the most important aspect of the cutaneous examination. Over time, these primary lesions may continue to develop or be modified by regression or trauma, producing "secondary lesions." However, with that being stated, the lack of standardization of basic dermatologic terminology has been one of the principal barriers to successful communication among physicians in describing cutaneous findings. Nevertheless, there are some commonly accepted terms used to describe the macroscopic morphology, configuration, and distribution of skin lesions, which are listed below.

Steps to prevent diabetic foot ulcers include frequent review by a foot specialist, good foot hygiene, diabetic socks and shoes, as well as avoiding injury.

- Foot-care education combined with increased surveillance can reduce the incidence of serious foot lesions.

X-ray applications on most cases have brought about little outcome in most of the published case reports. As a consequence, a certain number of authors consider acrogeria mainly as a cutaneous affection, but the bone alterations are well described as part of the syndrome.

For patients who show typical alterations of acrogeria and metageria, in a concomitant way, the single term of "Acrometageria" has been proposed, which can refer to the widest spectrum of premature ageing syndromes.

However, this concept is still not generally accepted in the medical literature.As these are extremely rare syndromes, all sharing an aspect of aging skin similar to progeria, they are also called progeroid syndromes, from time to time.

A urologist may be able to diagnose the disease and suggest treatment. An ultrasound can provide conclusive evidence of Peyronie's disease, ruling out congenital curvature or other disorders.

A systematic review has not found evidence that creams and oils are useful for preventing or reducing stretch marks in pregnancy. The safety in pregnancy of one ingredient, Centella asiatica, has been questioned. Evidence on treatments for reducing the appearance of the scars after pregnancy is limited.

There is currently no specific treatment available for either of these so-called progeroid syndromes. With this in mind, what is most important when making a differential diagnosis with them is based on the prognosis, which appears to be far better in acrogeria.

The elastic fibers will be highlighted by a Weigert or von Gieson elastic stains.

Given the anatomic site, a spindle cell lipoma, nuchal-type fibroma and fibromatosis colli are all included in the differential diagnosis.

Elastosis perforans serpiginosa is a unique perforating disorder characterized by transepidermal elimination of elastic fibers and distinctive clinical lesions, which are serpiginous in distribution and can be associated with specific diseases.

Assessment of diabetic foot ulcer includes identifying risk factors such as diabetic peripheral neuropathy, noting that 50 percent of people are asymptomatic, and ruling out other causes of peripheral neuropathy such as alcohol abuse and spinal injury.

The location of the ulcer, its size, shape, depth and whether the tissue is granulating or sloughy needs to be considered. Further considerations include whether the there is malodour, condition of the border of the wound and palpable bone and sinus formation should be investigated. Signs of infection require to be considered such as development of grey or yellow tissue, purulent discharge, unpleasant smell, sinus, undermined edges and exposure of bone or tendon.

Identification of diabetic foot in medical databases, such as commercial claims and prescription data, is complicated by the lack of a specific ICD-9 code for diabetic foot and variation in coding practices. The following codes indicate ulcer of the lower limb or foot:

- 707.1 Ulcer of lower limbs, except pressure ulcer

- 707.14 Ulcer of heel and midfoot

- 707.15 Ulcer of other part of foot

- 707.19 Ulcer of other part of lower limb

One or more codes, in combination with a current or prior diagnosis of diabetes may be sufficient to conclude diabetic foot:

- 250.0 Diabetes Mellitus

- 250.8 Diabetes with other specified manifestations

The diagnostic criteria for PXE are the typical skin biopsy appearance and the presence of angioid streaks in the retina. Other systems have become somewhat outdated by the discovery of the "ABCC6" mutations.

Cases of lymphangioma are diagnosed by histopathologic inspection. In prenatal cases, cystic lymphangioma is diagnosed using an ultrasound; when confirmed amniocentesis may be recommended to check for associated genetic disorders.

Stasis Papillomatosis is similar to AGEP (Acute generalized exanthematous pustulosis) from pustular psoriasis; criteria for histopathologic distinction have been proposed: papillary edema, vasculitis, exocytosis of eosinophils and single-cell necrosis of keratinocytes in AGEP and acanthosis and papillomatosis in pustular psoriasis.

An example that illustrates the difference between SP and Stasis Papillomatosis and the histology diagnosis is … “a markedly obese, 41-year-old Japanese man who had suffered from psoriasis vulgaris for several years visited hospital with elephantiasis-like swelling of his lower legs of three months' duration. His right lower leg showed marked papillomatosis with thick scales, and the left lower leg was eroded and papillomatous. Although direct lymphography of his lower extremities showed no abnormality, indirect lymphography revealed local lymphatic damage in the involved skin”. Histological examination showed hyperkeratosis, marked papillomatosis, proliferation of capillaries in the upper dermis, and lymphectasia in the lower dermis. It was suspected that obesity and the preceding psoriatic lesions caused local lymphatic disturbances, followed by the development of stasis papillomatosis.
