An unusual variant of malignant pilomatrixoma displaying melanization of epithelial elements is described. Melanization is a rare event even in the benign form of this adnexal neoplasm. Previously reported cases of malignant pilomatrixoma are reviewed; none containing pigment have been previously reported to our knowledge. Possible etiologies for lack of pigment in most benign and malignant pilomatrixoma are discussed.
本文描述了一种罕见的恶性毛母质瘤变异型，其上皮成分出现黑素沉着。即使在这种附属器肿瘤的良性形式中，黑素沉着也是罕见的现象。我们回顾了先前报道的恶性毛母质瘤病例；据我们所知，此前尚无含色素的病例报道。本文还讨论了大多数良性和恶性毛母质瘤缺乏色素的可能病因。
