Sebaceous carcinoma is a neoplastic growth of sebaceous glands. It is predominantly seen in the head and neck region given the high density of sebaceous glands in this region. The periocular region, which includes the meibomian, Zeis, and sebaceous glands of the caruncle and eyelid, is the most common site accounting for up to 75% of SGc. [6]
Occasionally, several adjacent glands will coalesce into a larger cauliflower-like cluster similar to sebaceous hyperplasia of the skin. In such an instance, it may be difficult to determine whether or not to diagnose the lesion as sebaceous hyperplasia or sebaceous adenoma. The distinction may be moot because both entities have the same ...
Meibomian glands (also called tarsal glands, palpebral glands, and tarsoconjunctival glands) are sebaceous glands along the rims of the eyelid inside the tarsal plate. They produce meibum , an oily substance that prevents evaporation of the eye's tear film .
Treatment is dependent on the specific type of cancer, location of the cancer, age of the person, and whether the cancer is primary or a recurrence. For a small basal-cell cancer in a young person, the treatment with the best cure rate (Mohs surgery or CCPDMA) might be indicated. In the case of an elderly frail man with multiple complicating ...
Spiradenomas (SA) are rare, benign cutaneous adnexal tumors that may progress to become their malignant counterparts, i.e. spiradenocarcinomas (SAC). Cutaneous adnexal tumors are a group of skin tumors consisting of tissues that have differentiated (i.e. matured from stem cells) towards one of the four primary adnexal structures found in normal skin: hair follicles, sebaceous sweat glands ...
As with all oil glands, lacrimal caruncles can become clogged, causing a pimple, whitehead, or pustule beneath the skin. Clogged oil and sweat glands in the caruncle can affect tear ducts. Treatment for dry eyes due to clogged glands includes refraining from rubbing the eyes and rinsing the eyes with clear water frequently during the day ...
There are also fewer oil glands in the neck when compared to the face, she adds, meaning the area is more prone to dryness. The neck muscles (technical term: platysma ) are also very strong—and ...
A review of treatments showed that the anti-mite drug ivermectin can be an effective treatment for reducing symptoms. [24] Eye drops or ointments containing corticosteroids are frequently used in conjunction with antibiotics and can reduce eyelid inflammation. [4] [5] [25] The supplement n-acetylcysteine may be effective for blepharitis. [26]
