目的:探讨毛母质瘤(PM)临床表现及病理特征。方法:回顾性分析399例PM的临床及组织病理资料。结果:绝大部分患者表现为单发(99%)、质硬或韧皮损,直径平均1.22cm;发病年龄<30岁占56.39%,男女比例为1∶1.33;好发于头颈部及上肢(83.37%);镜下主要以位于中央呈嗜酸性染色的影细胞和周围嗜碱性染色的嗜碱性细胞组成不规则条索或团块为特征。结论:PM是一种缓慢发生的良性皮肤肿瘤,可表现为急性加重,临床表现具有多样性,易误诊误治。因此,对于头颈部及上肢质硬或韧结节应早期手术彻底切除,以减少手术创伤,预防其他的并发症发生。
Objective: To investigate the clinical manifestations and pathological features of hairy tumor (PM). Methods: A retrospective analysis of 399 cases of PM clinical and histopathological data. Results: Most patients showed solitary (99%), hard or phloem lesions with an average diameter of 1.22cm. The age of onset was <30 years, accounting for 56.39%, the ratio of male to female was 1: 1.33. The upper limbs (83.37%) were mainly composed of irregular cords or clumps formed by eosinophilic phantom cells located in the center and peripheral basophilic basophils. Conclusion: PM is a benign skin tumor that occurs slowly, which can be manifested as acute exacerbation. The clinical manifestations are diversified and easily misdiagnosed and mistaken. Therefore, head and neck and upper extremity hard or tough section should be completely removed early surgery to reduce surgical trauma and prevent other complications.
