  • Surgical Removal of Epidermoid and Pilar Cysts Policy
    CLINICAL POLICY ADVISORY GROUP (CPAG) Surgical Removal of Epidermoid and Pilar Cysts Policy Statement Derby and Derbyshire CCG has deemed that the surgical removal of epidermoid/ pilar (sebaceous) cysts should not routinely be commissioned, unless one (or more) of the following criteria are met: 1. The epidermoid/ pilar (sebaceous) cyst is on the face (not scalp or neck) AND is greater than 1cm diameter, 2. The epidermoid/ pilar (sebaceous) cyst is on the the body (including scalp/ neck) AND is greater than 1cm on AND the epidermoid/ pilar (sebaceous) cyst is: • Associated with significant pain, Or, • Causing loss of function Or, • Susceptible to recurrent trauma These commissioning intentions will be reviewed periodically. This is to ensure affordability against other services commissioned by the CCG. Surgical Removal of Epidermoid Cysts Policy Updated: July 2021 Review Date: June 2024 Page 1 of 4 1. Background A skin cyst is a fluid-filled lump just underneath the skin. They are common and harmless and may disappear without treatment. Cysts can range in size from smaller than a pea to a few centimetres across. They grow slowly. Skin cysts do not usually hurt, but can become tender, sore and red if they become infected. Epidermoid cysts (commonly known as “sebaceous cysts’) are one of the main types of cysts and are always benign. They are commonly found on the face, neck, chest, shoulders or skin around the genitals. Cysts that form around hair follicles are known as pilar cysts and are often found on the scalp. Pilar cysts typically affect middle-aged adults, mostly women.

  • Fundamentals of Dermatology Describing Rashes and Lesions
    Dermatology for the Non-Dermatologist May 30 – June 3, 2018 - 1 - Fundamentals of Dermatology Describing Rashes and Lesions History remains ESSENTIAL to establish diagnosis – duration, treatments, prior history of skin conditions, drug use, systemic illness, etc., etc. Historical characteristics of lesions and rashes are also key elements of the description. Painful vs. painless? Pruritic? Burning sensation? Key descriptive elements – 1- definition and morphology of the lesion, 2- location and the extent of the disease. DEFINITIONS: Atrophy: Thinning of the epidermis and/or dermis causing a shiny appearance or fine wrinkling and/or depression of the skin (common causes: steroids, sudden weight gain, “stretch marks”) Bulla: Circumscribed superficial collection of fluid below or within the epidermis > 5mm (if <5mm vesicle), may be formed by the coalescence of vesicles (blister) Burrow: A linear, “threadlike” elevation of the skin, typically a few millimeters long. (scabies) Comedo: A plugged sebaceous follicle, such as closed (whitehead) & open comedones (blackhead) in acne Crust: Dried residue of serum, blood or pus (scab) Cyst: A circumscribed, usually slightly compressible, round, walled lesion, below the epidermis, may be filled with fluid or semi-solid material (sebaceous cyst, cystic acne) Dermatitis: nonspecific term for inflammation of the skin (many possible causes); may be a specific condition, e.g. atopic dermatitis Eczema: a generic term for acute or chronic inflammatory conditions of the skin. Typically appears erythematous,

  • Epidermoid Cyst
    Epidermoid cyst Most commonly known as a sebaceous cyst but also known as epidermoid inclusion cyst, Infundibular cyst, epidermal cyst, epidermal inclusion cyst. What is an epidermoid cyst? An epidermoid cyst is a benign walled-off cavity filled with keratin which originates from the hair follicle unit. What causes an epidermoid cyst? Epidermoid cysts are the most common type of cyst. They may be primary or they may arise from disrupted follicular structures due to trauma or comedone formation (blackheads). Multiple cysts may occur in the conjunction with acne vulgaris, Gardner syndrome and in nevoid basal cell carcinoma syndrome. Tiny superficial epidermoid cysts are known as milia. What does it look like? Epidermoid cysts appear as flesh coloured to yellowish, firm, round nodules of variable size. A central pore or punctum may be present. They are usually syptoless ut soeties disharge a foul sellig, heese-like aterial. Less frequently, the cysts can be painful due to inflammation or infection. How is an epidermoid cyst diagnosed? The diagnosis is usually made by a clinical examination. Sometimes a biopsy may be needed. How is epidermoid cyst treated? . Epidermoid cysts that do not concern a person need not be treated. Inflamed epidermoid cysts may require treatments with antibiotics. Incision, drainage and/or steroid injections may be helpful in rare cases to speed up the resolution of the inflammation. Non-inflamed cysts can be removed surgically and the contents and wall of the cyst drained. However, the cyst may recur if the entire cyst wall is not removed. .

Kalb, M.D. Phone: (716) 630-1102 Fax: (716) 633-6507 Department of Dermatology 325 Essjay Road Williamsville, New York 14221 2 FOOT- 1 HAND SYNDROME 2 foot - 1 hand syndrome is a superficial infection of the skin caused by the common athlete's foot fungus. It is quite common for people to have a minor amount of an athlete's foot condition. This would appear as slight scaling and/or itching between the toes. In addition, patients may have thickened toenails as part of the athlete's foot condition. Again the problem on the feet is very common and often patients are not even aware of it. In some patients, however, the athlete's foot fungus can spread to another area of the body. For some strange and unknown reason, it seems to affect only one hand. That is why the condition is called 2 foot - 1 hand syndrome. It is not clear why the problem develops in only one hand or why the right or left is involved in some patients. Fortunately there is very effective treatment to control this minor skin problem. If the problem with the superficial fungus infection is confined to the skin, then a short course of treatment with an oral antibiotic is all that is required. This antibiotic is very safe and normally clears the skin up fairly rapidly. It is often used with a topical cream to speed the healing process. If, however, the fingernails of the affected hand are also involved then a more prolonged course of the antibiotic will be necessary.

Benharroch*† *Department of Pathology, Soroka University Medical Center, Beer-Sheva, Israel; †Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva, Israel; and ‡Department of Surgery B, Soroka University Medical Center, Beer-Sheva, Israel doi:10.1111/j.1365-2230.2009.03272.x Summary Pilonidal sinuses usually occur in the sacrococcygeal area in young men, and occasionally can be found in other ectopic sites. We present a retrospective case review on unusual locations of pilonidal sinuses in the past 4 years. The lesion sites were as follows: one on the penis, two on the scalp, two on the abdomen, one on the neck, two in the groin and two in the axilla. Abdominal and penile lesions are uncommon, but the other locations reported are unusually rare. To our knowledge, the groin has not been reported previously as a site of a pilonidal sinus, although the histological appearance of hidradenitis suppurativa may well resemble it. When trying to clarify the pathogenesis of these occurrences, we found that recurrent hair removal was a common characteristic of the patients we contacted, and this may have been the initiating trauma. Pilonidal sinuses are found most often in the sacro- (EC). Genuine pilonidal sinuses or cysts had to show one coccygeal area in young men. These cysts are consid- or both of the following histological features: sinuses ered to be a result of excessive and repetitive trauma.

The purpose of this study was to explore these patients characteristics, there clinical manifestation, mode of treatment and microbiology. Methods: Hospitalized women with a diagnosis of major labia abscess were followed at the gynecological division of a university-affiliated tertiary medical center during January 2004 to December 2013. Decision for hospitalization was based on clinical symptoms such as severe pain, fever, swelling, redness and cellulitis, or no response to oral antibiotic treatment. Data on demographic parameters, age, clinical manifestations, diagnosis, mode of treatment, pus culture, blood test results, duration of stay and discharge were retrieved from the departmental computerized health records. Results: Of 294 women diagnosed and hospitalized for vulvar abscess during the study period, only 27 (9.2%) were diagnosed with major labia abscess and comprised the study group. Mean age was 35.2 ± 13.2 years (range 15-65 years). For all women, this was the first episode of labial abscess. Severe local pain was the main complaint, recorded for 17 (62.9%). Systemic fever and leukocytosis were recorded for only 8 (29.6%) and 10 (37.0%) women. Incision and drainage of the abscess was successful in all cases. There were no cases of recurrent OPEN ACCESS labial abscesses in our records.
