“…The majority of cases are negative for desmin, but rare cases of focal desmin reactivity have been reported [2,5,15,16]. In our case, the strong SMA expression and lack of CD34 staining ruled out hemangiopericytoma and solitary myofibroma [17][18][19]. MPC and angioleiomyoma have overlapping clinicopathologic and immunohistochemical features and are considered to exist on a single spectrum of tumors [15].…”

a b s t r a c tMyopericytomas (MPCs) are rare tumors that originate from perivascular myoid cells and are typically found in middle-aged men. MPCs are most commonly found in the distal extremities, but a number of reports indicate that MPC can occur in the head, neck, and oral cavity. Here, we report a case of a 12-yearold boy with MPC in the left coronoid process, which we believe to be the second reported case in the mandible. The patient underwent surgery to excise the tumor. Its avascular nature and low mitoses strongly suggested that the tumor was benign, in accord with most reported MPCs. Histology and immunohistochemistry revealed that the tumor displayed features most consistent with MPC and angioleiomyoma. The rare occurrence and broad spectrum of growth features make MPCs difficult to identify and classify. Future work is required to better characterize MPC.

“…Most cases of myopericytoma behave in a benign fashion, although a few malignant and/or recurring cases were described (6,9). In the oral cavity only a case of myopericytoma of low grade malignancy was reported (11).…”

“…It mostly arises within the skin and subcutaneous tissues of extremities (3). Myopericytoma of the oral cavity is extremely rare, only several cases have been reported in the literature (2,(4)(5)(6)(7). To the best of our knowledge, there is only two reported cases of myopericytoma localized to the tongue (4,5).…”

Myopericytoma is a rare benign tumour composed of pericytic cells that show myoid differentiation and have a tendency for concentric perivascular growth. It belongs to a spectrum ofperivascular myoid cell neoplasms. To date, only a small number of cases of myopericytoma involving the oral cavity have been reported. We describe a case of myopericytoma presenting as a slowly growing tongue nodule in a 61-year-old woman. A diagnosis of myopericytoma was established with the histopathological findings combined with immunohistochemical staining. Myopericytoma should be included in the differential diagnosis of well-circumscribed, slow-growing lesions of the oral cavity.

“…In our case, the patient had a painless, slowly growing nodule in the subcutaneous tissue of the lower leg. Most cases of MP are benign lesions, although a few recurring and/or malignant cases have been described 7,[11][12][13] . It seems that the clinical outcome of rare malignant myopericytoma is strongly associated with the depth of the neoplasm.…”
