INTRODUCTION
Trichilemmomas are a form of benign adnexal neoplasm with differentiation toward the follicular outer sheath. Nevus sebaceous (NS) of Jadassohn is a congenital malformation characterized as a nonhereditary hamartoma of the adnexal structures of the skin, mainly the pilosebaceous unit. NS represents a fertile field for the development of secondary adnexal neoplasms, commonly benign but occasionally malignant. To our knowledge, one case of a pigmented desmoplastic trichilemmoma (DT) has been reported in the English literature.
CASE PRESENTATION
We report a case of a 36-year-old male with pigmented DT that developed on long-standing congenital NS, mimicking pigmented basal cell carcinoma (BCC), which was successfully excised with 4-mm margins.
CONCLUSION
Pigmented DT may mimic pigmented BCC on clinical and dermatoscopic examination; therefore, histological evaluation is always recommended to confirm the diagnosis.
引言
毛发瘤是一种良性附属器肿瘤，向毛囊外鞘分化。 Jadassohn皮脂腺痣（NS）是一种先天性畸形，其特征为皮肤附属器结构的非遗传性错构瘤，主要是毛囊皮脂腺单位。NS是继发性附属器肿瘤发生的沃土，通常为良性，但偶尔为恶性。据我们所知，英文文献中报道过1例色素性促纤维增生性毛发瘤（DT）。
病例报告
我们报告1例36岁男性，其色素性DT发生于长期存在的先天性NS上，酷似色素性基底细胞癌（BCC），成功切除，切缘4毫米。
结论
色素性DT在临床和皮肤镜检查中可能酷似色素性BCC；因此，总是建议进行组织学评估以确诊。
