An acanthoma is a skin neoplasm composed of squamous or epidermal cells. It is located in the prickle cell layer. [DorlandsDict|one/000000513|acanthoma]

Types of acanthoma include pilar sheath acanthoma, a benign follicular tumor usually of the upper lip; clear cell acanthoma, a benign tumor found most frequently on the legs; and Degos acanthoma, often confused with but unrelated to Degos disease.

History

In 2005, "Acanthoma" was added to MeSH as an index term; previous indexing was "Skin Neoplasms" (1965-2004). [ [http://www.nlm.nih.gov/pubs/techbull/nd04/nd04_med_data_changes.html Medline Data Changes for 2005] NLM Technical Bulletin 2004 November-December; 341] At that time, PubMed indexed only 206 articles with the term "acanthoma" (the term usually in the title or abstract).
