Proliferating trichilemmal tumor (PTT) is a benign tumor arising from the isthmic portion of the hair follicle. Malignant transformation in PPT is very rare and unusual. Indeed, only about sixty well-documented cases have been found in the English literature. We present here the case of a 72-year-old patient with an exceptional combination of malignant trichilemmal carcinoma and basal cell carcinoma, occurring on actinic keratosis lesions. The aim of this work is to describe the diagnostic and therapeutic modalities of this association which is exceptional.
增殖性毛鞘瘤(PTT)是一种起源于毛囊峡部的良性肿瘤。PTT 中的恶性转化非常罕见且不常见。事实上,在英文文献中仅发现了约六十例有充分记录的病例。我们在此介绍了一位 72 岁患者的病例,其在光化性角化病病变上出现了罕见的恶性毛鞘癌和基底细胞癌的组合。本研究的目的是描述这种罕见的联合的诊断和治疗方式。
