BACKGROUND Proliferating trichilemmal cysts, also referred to as pilar cysts, are benign adnexal tumors in the scalp diagnosed most commonly in middle-aged women. The cysts can be large and require careful surgical resection, as malignant variants can exist. Although uncommon, it is rare for these tumors to reach large sizes. This report describes a 69-year-old woman with an occipital giant proliferating trichilemmal (pilar) cyst treated with surgical resection and flap reconstruction. CASE REPORT A 69-year-old female patient presented with a slowly growing mass in the occipital region of the head, which had been present for 11 years. The mass exhibited areas of hyperkeratosis and an unpleasant odor. The tumor was first excised with electrocautery to minimize bleeding during removal. We initially attempted to repair the defect using a local rotation skin flap. Although this approach provided some coverage, it quickly became clear that the available tissue would not be enough. As a result, we decided to supplement the repair with a supraclavicular artery island flap to ensure adequate closure. CONCLUSIONS This case highlights how crucial it is to combine thorough clinical evaluation, imaging, and histopathological analysis when dealing with proliferative pilar tumors. In this instance, we successfully removed a large tumor located in the occipital region of a 69-year-old woman. The diagnosis was later confirmed histologically as a benign proliferative pilar tumor. Regular follow-up is essential to ensure the absence of recurrence and to address potential future complications.
增殖性外毛根鞘囊肿，也称为毛发囊肿，是头皮上的良性附属器肿瘤，最常见于中年女性。囊肿可能很大，需要仔细手术切除，因为可能存在恶性变体。虽然不常见，但这些肿瘤长到很大尺寸的情况很少见。本报告描述了一名69岁女性，患有枕部巨大增殖性外毛根鞘（毛发）囊肿，接受了手术切除和皮瓣重建治疗。病例报告：一名69岁女性患者，枕部出现一个缓慢生长的肿块，已存在11年。肿块有角化过度区域且有异味。最初用电灼切除肿瘤以减少切除过程中的出血。我们最初尝试使用局部旋转皮瓣修复缺损。尽管这种方法提供了一些覆盖，但很快发现可用组织不够。因此，我们决定用锁骨下动脉岛状皮瓣补充修复以确保充分闭合。结论：本病例突出了在处理增殖性毛发肿瘤时，综合全面的临床评估、影像学检查和组织病理学分析的重要性。在这个病例中，我们成功切除了一名69岁女性枕部的一个大肿瘤。后来组织学诊断证实为良性增殖性毛发肿瘤。定期随访对于确保无复发和处理潜在的未来并发症至关重要。
