First described by Malherbe in 1880 as a calcifying epithelioma
, (1) the lesion would eventually be termed a pilomatricoma or pilomatrixoma.
10,14] Chondroid syringoma may be confused clinically with epidermal cyst, dermatofibroma, pilomatricoma, neurofibroma, histiocytoma, seborrheic keratosis, calcifying epithelioma
and basal cell carcinoma.
Pilomatricoma (PM; calcifying epithelioma
of Malherbe) is a benign tumor originating from the matrix of the hair follicles (1).
Pilomatrixoma is a rare benign skin tumor arising from hair follicle stem cells which is also known as calcifying epithelioma
Background and Design: Pilomatrixoma calcifying epithelioma
of Malherbe is a rare, benign, limited, calcifying epithelial neoplasm that arises from the hair pluripotent precursor matrix cells.
1) The tumor was first described in 1880 by Malherbe and Chenantais, who believed that it arose from the sebaceous gland and called it as calcifying epithelioma
Giant calcifying epithelioma
of Malherbe (pilomatrixoma): imaging features.
Demonstration of calcification, which is normally a feature of pilomatricoma (hence its other name of calcifying epithelioma
of Malherbe), is variable on MRI.
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
DISCUSSION WITH LITERATURE REVIEW: Pilomatrixoma is a relatively uncommon benign tumor of hair matrix differentiation, first described by Malherbe as benign calcifying epithelioma
, as a tumor of the sebaceous gland.
Tsoitis G, Mandineos C, Kanitakis JC: Perforating calcifying epithelioma
of Malherbe with a rapid evolution.
It was initially thought to arise from sebaceous glands and was called calcifying epithelioma
of Malherbe by Malherbe and Chenantais in 1880.
