Epithelioma

 

a benign or malignant tumor arising from surface epithelium, mainly of the skin and its appendages. In the USSR, the term is applied only to several rare skin tumors, for example, blue nevus (Borst-Jadossohn intradermal epithelioma) and calcifying epithelioma of Malherbe (pilomatricoma). It was formerly used to designate basal cell carcinoma (basal cell epithelioma) and squamous cell carcinoma of the skin (spinocellular epithelioma).
