Epithelioma Malignant

Malignant epithelioma (oncoepitheliomatosis, epithelioma carcinoma) is a rare and aggressive malignant tumor. Accounts for 0.5-2% of all skin cancers. It occurs equally often in men and women (the proportion of Weitbrecht-Schreckenberg syndrome among men in different regions is from 3 to 11%), the incidence increases sharply in people over 40 years of age. Epitheliomas occupy one of the first places in the structure of uveal melanoma and metastasize predominantly hematogenously.
