Epitelioma (epithelioma) - the name of different epithelial tumors; currently the term "epitelioma" is usually applied to determine skin tumors, developing out of the skin and its appendages.
Distinguish epitelioma: basal cell (see basal cell carcinoma), spinocellular (see Skin tumors) and adenoid cystic (see Epithelioma adenoides cysticum).
A rare form of basal cell carcinoma is epitelioma Kamarulzaman described Daria (J. Darier) as a flat scar or ulcerative-cicatricial epitelioma (epithelioma planum cicatrisans). It begins with the appearance of a lump-"pearls", after the collapse of which formed surface ulcer surrounded by dense brilliant roller whitish color. The plague slowly increases in size due to peripheral growth, at the same time being subject to a separate sites scarring. The most frequent localization - face.
The disease lasts for years, described the rare cases of conversion in ulcerative squamous cell carcinoma.
Also rare is epitelioma calcified [Malherbe and Senate (A. Malherbe, J. Chenantais)] - single, round, rocky density mobile node size from a pea to chicken eggs, located deep in the dermis. Localization: the scalp, face, neck. Occurs in childhood from the sebaceous glands, adsorbing epithelial rudiments, grows very slowly. Histologically determined connective tissue capsule inside which is located fibrous stroma with plots parenchyma, consisting of dark cells and the so-called cell-shadows. Characteristic parenchymal necrosis, calcification unstable and can be secondary. The treatment is surgical removal.
