Schwannomas or neurilemmomas are rare, benign, and usually solitary lesions that arise from the nerve sheath. In the majority of cases, these tumors involve the extremities, head, neck, and trunk.
In the present study, a 52-year-old man presented to our surgical department for the evaluation of a symptomatic lump in his left lateral abdominal wall. CT and MRI confirmed the presence of a cystic mass located between the external and internal oblique muscles. Histopathology and immunohistochemistry confirmed it to be benign schwannoma.
Schwannomas have rarely been reported in the abdominal wall. To the best of our knowledge, this is the first case of schwannoma located in the left upper abdominal wall and the fifth case of abdominal wall schwannoma reported according to the reviewed medical literature.
Benign schwannoma should be included in the differential diagnosis of cystic and symptomatic lesions of the abdominal wall. The treatment of choice is surgical excision, and recurrence is extremely rare.
施万细胞瘤或神经鞘瘤是罕见的良性肿瘤，通常为单发，起源于神经鞘。大多数情况下，这些肿瘤累及四肢、头部、颈部和躯干。
在本研究中，一名52岁男性因左侧腹壁出现有症状肿块前来我院外科就诊。CT和MRI证实腹外斜肌和腹内斜肌之间存在一个囊性肿块。组织病理学和免疫组化证实为良性施万细胞瘤。
腹壁施万细胞瘤鲜有报道。据我们所知，这是首例位于左上腹壁的施万细胞瘤，也是经查阅医学文献报道的第五例腹壁施万细胞瘤。
腹壁囊性和有症状病变的鉴别诊断应包括良性施万细胞瘤。首选治疗方法是手术切除，复发极为罕见。
