Acanthoma
Definition
A benign cutaneous tumor formation characterized by the hyperplastic proliferation of keratinocytes within the stratum spinosum of the epidermis (acanthosis). This well-circumscribed lesion can manifest in various clinical and histological forms, the most notable being clear cell acanthoma (Degos) and acanthoma fissuratum, requiring microscopic differential diagnosis to exclude epidermal malignancies.
