Pilomatricoma or benign calcifying epithelioma of Malherbe is a benign appendageal tumour originating from primitive cells of the hair matrix. Perforation (transepidermal elimination), bullous or anetodermic cutaneous changes overlying pilomatricomas are rare events. In this report, we describe a case of pilomatricoma with bullous appearance or secondary anetoderma. The tumour was totally excis...

Calcifying cystic odontogenic tumor (CCOT) previously known as calcifying odontogenic cyst (COC) is a relatively rare lesion. It was first reported as a separate pathologic entity by Gorlin et al in 1962 as a likely analog of the cutaneous calcifying epithelioma of Malherbe or pilomatricoma. Because of the diverse clinicohistologic features and the various neoplastic potential, there have been ...

PURPOSE The purpose of this study was to describe the clinical and sonographic features of calcifying epitheliomas (pilomatrixomas). METHODS We retrospectively reviewed the clinical data and sonographic appearances of 59 cases of calcifying epitheliomas in 58 patients that were confirmed pathologically. RESULTS The mean age of the patients was 26 years (range, 5-69 years) and the female-to-...

Pilomatrixoma, also known as calcifying epithelioma of Malherbe, is a benign tumor of hair cell origin. It is an unusual, but not particularly rare, tumor. Fifty percent or more of pilomatrixomas occur in the head and neck, and 40% occur in patients under 10 years of age. Pilomatrixomas may be mistaken for cysts, calcified lymph nodes, calcified hematomas or hemangiomas, or parotid gland tumors...

Pilomatrixoma or calcifying epithelioma of Malherbe is a rare, benign, skin tumour originating from piliferous follicles; breast localization is considered to be very rare. These lesions can origin from the peri-areolar piliferous bulbs and, due to the clinical and imaging features, be easily misdiagnosed as a breast neoplasm. We present a case of pilomatrixoma of the left breast in a woman of ...
