Myopericytoma (MPC) is an uncommon benign neoplasm of the skin and soft tissues belonging to a spectrum of tumors that are histologically recognized by their distinctive perivascular myoid cell differentiation. These distinct tumors are more prevalent among middle-aged males, and they arise more frequently in the subcutaneous tissue of the four extremities. In this paper, myopericytoma is reported in a 59-year-old Saudi male, presented with a painless small cyst involving the left ankle suspected clinically to be a ganglion cyst. Following surgical excision of the cyst, the diagnosis of myopericytoma was made based on the histopathological pattern of the disease. This paper focuses on the clinical and histopathological findings of myopericytoma and emphasizes the importance of immunohistochemistry as well as molecular testing in reaching the final diagnosis.
肌周细胞瘤（MPC）是一种皮肤和软组织的罕见良性肿瘤，属于一组肿瘤，在组织学上可通过其独特的血管周围肌样细胞分化来识别。这些独特的肿瘤在中年男性中更为常见，且更频繁地发生于四肢的皮下组织。本文报道了一名59岁的沙特男性肌周细胞瘤病例，该患者左踝出现一个无痛性小囊肿，临床怀疑为腱鞘囊肿。囊肿手术切除后，根据疾病的组织病理学模式做出了肌周细胞瘤的诊断。本文重点关注肌周细胞瘤的临床和组织病理学发现，并强调免疫组织化学以及分子检测在最终诊断中的重要性。
