Published: August 2012

Myopericytoma is a benign tumor composed of cells that show apparent differentiation towards putative perivascular myoid cells called myopericytes. To date, only a small number of series describing myopericytomas have been reported. Here, we report a case of pulmonary myopericytoma presenting as multiple nodules in a 26-year-old man. Clinical presentation, radiological features and histopathologic findings of the patient are also discussed. The result of the histology combined with the immunohistochemical analysis led to a diagnosis of myopericytomas. To our knowledge, this is the first report of myopericytoma showing pulmonary involvement.

Myopericytoma is a rare benign smooth-muscle cell neoplasm of the subcutaneous soft tissues that is primarily found in young adults with a male predominance. We present the clinical, radiologic, and histopathologic features of a longstanding myopericytoma of the hand. We emphasize the features that help the radiologist and pathologist to accurately characterize this entity.

Myopericytoma is a rare perivascular myoid neoplasm that typically arises in the dermis or subcutaneous tissue, with an intravascular variant also reported. We present a case of an elderly man with a subcutaneous nodule in his lower leg that had persisted for four decades, accompanied by pain in the last several years. Imaging revealed a 20-mm elongated subcutaneous nodule along with a similar intraosseous lesion in the ipsilateral fibula.

Aim: Myopericytoma (MPC) is a rare tumour characterized by a perivascular proliferation of pericytic cells with myoid differentiation and a typical spindle shape. Except for the rare malignant cases, MPC mostly shows a benign course. Symptoms are often non-specific, and the diagnosis could be accidental.

Article Synopsis
  • A 4-year-old girl experienced speech issues and left-side weakness, leading to imaging that revealed multiple strokes and a significant right axillary artery aneurysm.
  • She underwent surgery to remove and reconstruct the aneurysm using a saphenous vein graft, but two years later, a new mass developed near the original surgery site.
  • Further examination revealed that the new progressive lesion originated from an undetected 1-mm myopericytoma found in scans after the initial procedure.
