Mg. Hanly et al., PILOMATRICAL CARCINOSARCOMA OF THE CHEEK WITH SUBSEQUENT PULMONARY METASTASES - A CASE-REPORT, The American journal of dermatopathology, 16(2), 1994, pp. 196-200
We report a case of malignant pilomatrixoma with a pronounced biphenot
ypic morphology. The lesion, which was excised from the cheek of a 36-
year-old man, was composed of a large pilomatrixoma lying within a spi
ndled, sarcomatoid stroma. Fourteen months later, the tumor metastasiz
ed to the right upper lobe of the lung. We describe the tumor's pathol
ogy, histology, and immunochemistry and discuss the differential diagn
osis. We also speculate on its histogenesis.
