Schwannomas or neurilemmomas are benign and slow-growing tumors that arise exclusively from Schwann cells in peripheral nerve sheaths. These neoplasms theoretically can occur anywhere in the body, but they most frequently affect extremities, as well as head and neck region. However, their presentation in the abdominal wall is extremely rare and only few cases have been reported in the literature. Subcutaneous lesions may be asymptomatic and only incidentally discovered upon physical examination or imaging. However, occasionally they induce mass effects on surrounding large nerves. We present the case of a 34-year-old man with abdominal wall pain localized in the right iliac fossa and palpable subcutaneous mass. Ultrasound and CT scan revealed a solid well-defined mass of the abdominal wall. Following surgical excision under general anesthesia, histological examination was consistent with the diagnosis of benign schwannoma.
施万细胞瘤或神经鞘瘤是良性且生长缓慢的肿瘤，仅起源于周围神经鞘中的施万细胞。从理论上讲，这些肿瘤可发生于身体的任何部位，但最常累及四肢以及头颈部区域。然而，它们在腹壁的表现极为罕见，文献中仅报道过少数病例。皮下病变可能无症状，仅在体格检查或影像学检查时偶然发现。不过，它们偶尔会对周围大神经产生占位效应。我们报告一例34岁男性病例，其腹壁疼痛位于右髂窝，可触及皮下肿块。超声和CT扫描显示腹壁有一个边界清晰的实性肿块。在全身麻醉下进行手术切除后，组织学检查结果与良性施万细胞瘤的诊断相符。
