Epithelioma Recurrent

Recurrent epithelioma, or epithelioid sarcoma, is a rare malignant neoplasm of human skin and mucous membranes. This is an uncommon tumor with a favorable prognosis.

Epitheliomas are divided into:

- simple (solid) epithelioma – a malignant tumor consisting of differentiated epithelial cells. This tumor is characterized by slow and meager growth (see photo No. 1); Photo 1 - simple epithelioma

Simple epithelioma consists of various components, but almost always it consists of an epithelial layer of the skin and its appendages (hairs, sebaceous glands), often resembling histologically the epidermis. In other words, such tumors are clinically and histologically similar to basal cell carcinoma (warts, pig spots, seborrheic keratoses, and warts vulgaris).
