Acral fibrokeratoma
Acral Fibrokeratoma
Acral fibrokeratoma (pronounced as ak-ral fy-bro-ker-a-to-ma) is a benign tumor that typically develops on the fingers, toes, or other acral sites.
Etymology
The term "acral" is derived from the Greek word "akron" meaning extremity, while "fibrokeratoma" is a combination of "fibro" (from Latin "fibra" meaning fiber), "kerato" (from Greek "keras" meaning horn), and "oma" (from Greek "onkos" meaning swelling or tumor). Thus, the term essentially refers to a fibrous, horn-like tumor on the extremities.
Description
Acral fibrokeratoma is characterized by a dome-shaped or finger-like projection of skin, often with a collarette of slightly raised skin at the base. The lesion is usually solitary and small, often less than 1 cm in diameter. The color can vary from flesh-colored to pink or brown.
Causes
The exact cause of acral fibrokeratoma is unknown. However, it is believed to be a reactive process to minor trauma or irritation.
Diagnosis
Diagnosis of acral fibrokeratoma is primarily based on clinical examination. A biopsy may be performed to confirm the diagnosis and rule out other conditions such as acrochordon (skin tag), cutaneous horn, or squamous cell carcinoma.
Treatment
Treatment is not necessary unless the lesion is causing discomfort or for cosmetic reasons. If treatment is desired, the most common method is surgical excision.
