A pilomatrixoma is a benign tumor originating from a hair follicle that most frequently occurs in the head-and-neck region. It usually presents as a subcutaneous, slow-growing, nodular, painless firm mass. There are few reported cases on eyelid pilomatrixoma. We reporting an unusual presentation of a rapidly growing pedunculated eyelid pilomatrixoma in a 29-year-old female patient. Surgical excision was performed, and histological examination showed a cavity containing proliferating cords of basaloid cells differentiated into eosinophilic keratinized shadow cells confirming the pilomatrixoma diagnosis. Only a few cases with pedunculated eyelid masses have been reported in the literature; pedunculated lesions can be misdiagnosed as vascular tumors or malignancies. Therefore, pilomatrixoma should be considered in the differential diagnosis of such a presentation. A complete excisional biopsy of the mass is diagnostic and therapeutic.
毛发上皮瘤是一种起源于毛囊的良性肿瘤，最常发生于头颈部区域。它通常表现为皮下缓慢生长的结节状无痛性坚实肿块。关于眼睑毛发上皮瘤的报道病例较少。我们报告了一名29岁女性患者中一种罕见的迅速生长的带蒂眼睑毛发上皮瘤表现。进行了手术切除，组织学检查显示一个腔隙，其中含有增殖的基底样细胞索，这些细胞分化为嗜酸性角化影细胞，证实了毛发上皮瘤的诊断。文献中仅报道了少数带蒂眼睑肿物的病例；带蒂病变可能被误诊为血管肿瘤或恶性肿瘤。因此，在这种表现的鉴别诊断中应考虑毛发上皮瘤。对肿物进行完整切除活检具有诊断和治疗意义。
