Schwannomas are slow-growing mesenchymal neoplasms that arise from Schwann cells with low malignant potential. These uncommon neoplasms are nerve sheath tumors that arise at almost any anatomical site. The majority of schwannomas are benign, and few are malignant. The current study presents the rare case of an anal schwannoma that was successfully treated by surgery; there are few such cases previously reported in the literature. The patient was admitted to hospital following the identification of a mass incidentally. The tumor was so large that it compressed the tissue around it, although no symptoms were caused. The pre-operative clinical diagnosis was inconclusive in this case, and a final diagnosis was established based on radiographic and histopathological examination. The current study aimed to provide a possible differential diagnosis for such anally-located masses.
施万细胞瘤是一种生长缓慢的间叶性肿瘤，起源于恶性潜能较低的施万细胞。这些不常见的肿瘤是神经鞘瘤，几乎可发生于任何解剖部位。大多数施万细胞瘤是良性的，恶性的很少。本研究报告了一例罕见的经手术成功治疗的肛门施万细胞瘤病例；此前文献报道的此类病例很少。患者因偶然发现肿块入院。肿瘤很大，虽未引起症状，但压迫了周围组织。该病例术前临床诊断不明确，最终诊断基于影像学和组织病理学检查。本研究旨在为这种位于肛门的肿块提供可能的鉴别诊断。
