with sebaceous differentiation (SESD) is a rare histologically distinctive benign tumor, described for the first time in 1980 by Rothko et al.
Pilomatrixoma which is also known as Malharbe's calcified epithelioma
currently was mentioned in 1861 in Wilcken's doctoral thesis and Malharbe and Chenantais defined the lesion as calcified epithelioma
in 1880 (2, 3).

The differential diagnosis includes dermal and subcutaneous masses (sebaceous cyst, epidermoid cyst, basal cell epithelioma
, gaint cell tumor and neurofi-broma), calcified lesions (calcified epidermoid cyst, foreign body reactions or calcified hematomas).

In 1880, Malherbe and Chenantais first described a pilomatrixoma as a benign calcifying tumor that they believed originated in the sebaceous glands; they called it a calcifying epithelioma
Pilomatricoma (PM; calcifying epithelioma
of Malherbe) is a benign tumor originating from the matrix of the hair follicles (1).
The identification of this rare cancer, known as multiple self-healing squamous epithelioma
(MSSE) or Ferguson-Smith disease, could pave the way for new drugs to treat other types of the disease, scientists have claimed.
