Proliferating trichilemmal tumors are uncommon neoplasms that are usually benign, but characterized by frequent local recurrence. In this report, we describe a patient who sought treatment at our clinic for a right occiput scalp nodule measuring 1 cm in diameter. The subcutaneous lesion was mobile and without overlying skin ulceration. Excisional biopsy of the mass was performed and the pathologic diagnosis returned as malignant, proliferating trichilemmal (pilar) tumor. Resection margins were free of tumor. On further examination the patient had no evidence of metastatic disease. A schedule of routine follow-up visits was arranged to monitor the site for recurrent disease.
增生性外毛根鞘瘤是一种罕见的肿瘤，通常为良性，但具有局部复发频繁的特点。在本报告中，我们描述了一名患者，他因右侧枕部头皮出现一个直径1厘米的结节到我们诊所就诊。皮下病变可活动，且其上皮肤无溃疡。对该肿物进行了切除活检，病理诊断为恶性增生性外毛根鞘（毛囊）瘤。切除边缘无肿瘤。进一步检查发现患者没有转移疾病的证据。安排了常规随访计划以监测该部位是否复发疾病。
