毛囊囊肿是毛囊起源的常见良性囊肿,其通常出现在含有致密毛囊的皮肤区域,例如头皮。在这里,我们描述了一个年轻女子的独特案例,她被发现手背有一个毛囊囊肿,相对缺乏毛囊皮脂腺的一个相当不典型的位置。此病例说明了毛囊囊肿表现的变异性以及在患有背侧肿瘤的患者的鉴别诊断中考虑毛囊囊肿的重要性。
Pilar cysts are common benign cysts of follicular origin that typically arise in areas of skin containing dense hair follicles such as the scalp. Here we describe a unique case of a young woman who was found to have a pilar cyst on the dorsum of her hand, a rather atypical location given the relative lack of pilosebaceous units. This case illustrates the variability in pilar cyst presentation and the importance of considering a pilar cyst in the differential diagnosis of a patient presenting with a tumor of the dorsal hand.
