Pilar tumor is a rare neoplasm arising from the external root sheath of the hair follicle and is most commonly observed on the scalp. These tumors are largely benign, often cystic, and are characterized by trichilemmal keratinization. Wide local excision has been the standard treatment. Recent reports have described a rare malignant variant with an aggressive clinical course and a propensity for nodal and distant metastases which, therefore, merits aggressive treatment. In this report, we present a case of malignant pilar tumor of the scalp with multiple nodal metastases at presentation. Diagnostic and therapeutic considerations, in the form of adjuvant radiotherapy, are subsequently discussed.
毛母质瘤是一种罕见的肿瘤，起源于毛囊外根鞘，最常见于头皮。这些肿瘤大多为良性，常呈囊性，其特征为毛透明角化。广泛局部切除一直是标准治疗方法。最近的报告描述了一种罕见的恶性变体，其临床病程侵袭性强，有发生淋巴结和远处转移的倾向，因此需要积极治疗。在本报告中，我们呈现了一例头皮恶性毛母质瘤，就诊时已有多处淋巴结转移。随后将讨论以辅助放疗形式进行的诊断和治疗考量。
