The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



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).

Demonstration of calcification, which is normally a feature of pilomatricoma (hence its other name of calcifying epithelioma of Malherbe), is variable on MRI.
Sebaceous carcinomas have significantly increased nuclear staining with p53 and Ki-67 (MIB-1) and reduced levels of BCL2 and p21, in comparison to sebaceous adenomas and sebaceous epitheliomas. The p53 protein is a tumor suppressor.
Since then, this uncommon entity has been called calcifying epithelioma of Malherbe (2).It was believed to be a rare tumor, but increasing reports in the literature show that it is not uncommon.
This lesion was first described in 1880 by Malherbe and Chenantais who thought it to arise from sebaceous glands and called it calcifying epitheliomas of Malherbe.
Broders, considering this information to be critical for patient care, then "transferred the grading system to the old pathologic reports in Mayo's files...and graded lesions forward to the point in the 1920s at which the grading of various squamous-cell epitheliomas had become routine." (2)
