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 Clear cell acanthoma is a rare benign (non-cancerous) epithelial skin tumour. It is usually a solitary lesion appearing on the lower legs but there have been cases of multiple lesions occurring.

Medical definition of acanthoma: a tumor originating in the skin and developing through excessive growth of skin cells especially of the stratum spinosum Keratoacanthoma is considered to be a variant of the keratinocyte or non- melanoma skin cancer, squamous cell carcinoma (SCC).

Keratoacanthoma may start at the site of a minor injury to sun-damaged and hair. Definition / general.

Keratoacanthoma is a well-differentiated variant of Squamous cell carcinoma.Clinically, it is distinguished by its initial rapid growth followed by spontaneous involution over a period of a few months. Dermoscopy criteria. White circles: White ring-like structures within the hair follicle; Keratin mass: Centrally located, amorphous, yellow-white to light brown areas without any recognizable. The exact cause of acanthoma is not known; it is sometimes called a benign tumor, and sometimes described as the result of inflammation. Acanthomas are not considered dangerous and do not require treatment, but they may be removed for cosmetic reasons or to relieve any associated symptoms
