“…This tumour has a wide histologic spectrum ranging from lesions very similar to myofibromatosis to tumours that closely resemble glomus tumours and angiomyoma [2]. Immunohistochemically, the tumour cells in myopericytoma are generally positive for SMA, vimentin, and h‐caldesmon and negative for desmin, CD34, cytokeratin, and S‐100 protein [5, 9, 11, 14]. In the present case, myoid tumour cells were positive for SMA and negative for CD34, CD31, and S‐100 protein.…”

Myopericytoma is a rare, usually benign soft tissue tumour that arises most commonly in the dermis and subcutaneous soft tissue of the lower extremities. In this article, we present an unusual case of myopericytoma occurring in the deep soft tissue around the knee that mimicked a neurogenic tumour. Myopericytoma can be confused with neurogenic tumour when located in deep soft tissue and adjacent to nerve bundles. Preoperative MRI and colour Doppler ultrasound may help differentiate myopericytoma from neurogenic tumour by revealing the hypervascular nature of the tumour.

“…15 According to the literature, preoperative Magnetic Resonance Imaging (MRI) and ultrasound examinations are inadequate or sometimes misleading. 16 Therefore, excisional biopsy and histological examination are essential for definitive diagnosis as performed in this case report. MPC is a slow-growing benign tumor, but in some cases, malignant transformation has also been reported, characterized histologically by pleomorphism, necrosis, and significant mitotic activity of tumor cells.…”

Myopericytoma (MPC) is defined as a benign mesenchymal neoplasm consisting mostly of oval spindle-shaped myoid-like cells with perivascular growth. Apart from being a rare lesion in all anatomical regions of the body, it is extremely rare in the oral and maxillofacial region and only a limited number of cases have been reported in the literature. We present here the case of MPC in a 42-year-old female patient who had a painless, enlarging lesion in the anterior mandible. Intraoral examination of the lesion revealed a smooth, nonwhite, pedunculated, fibrotic, painless, and nonbleeding lesion in the lingual aspect of the anterior mandible. Histopathologic examination revealed a tumor consisting of spherical/nodular structures composed of spindle cells and hemangioperistomatous vascular structures in the form of staghorn. These tumor cells showed no signs of malignancy. On immunohistochemical examination, the tumor cells were positive for CD34 and SMA. SMA Protein was also focally positive in nodular structures formed by spindle cells and tumor stroma. S-100 protein was negative in the lesion. To our knowledge, this is the second case of MPC that occurred in the mandibular gingiva.

Introduction. Myopericytoma is a very rare perivascular tumor that can be presented with painful mass in lower extremities. We aimed to present an atypical presentation and location of myopericytoma. Presentation of Case. An 18-year-old otherwise healthy individual was admitted to outpatient clinic with complaints of numbness and pain in his right hand. He has had no trauma. On volar aspect of his right hand, a well-circumscribed, painful mass was palpated. MRI results were related to hemangioma. Surgical excision was planned and performed. Pathological investigation revealed the mass is myopericytoma. Discussion. This case demonstrates a rare location and presentation of myopericytoma. Reviewing the literature, discussion was made to expand the horizon for diagnosis and treatment of patients with similar symptoms. Conclusion. Myopericytoma can rarely present with numbness and pain in affected region. Surgical excision is helpful for definitive diagnosis and symptom relief.
