Abstract
Although myopericytoma and glomangiopericytoma are considered the subtypes of the group myopericytomas (MPC), they differ morphologically. Both of the tumors arise from pericytic cells. Scalp MPC are infrequent, but extranasal glomangiopericytomas are extremely rare. Herein, we report a case of a 36-year-old female presenting with slowly growing scalp swelling. Histopathology showed a dermal tumor with features of myopericytoma as well as glomangiopericytoma within the same lesion. Immunohistochemistry and reticulin staining confirmed pericytic origin but could not differentiate between the two tumors. This case report adds to the rarity and morphologic heterogeneity of the group MPC.

Abstract
Myopericytoma is a rare soft tissue tumor with a predilection for the distal extremities. It is commonly found in the skin and subcutaneous tissues and usually takes a benign course. Current knowledge is limited to isolated case series and reports; hence, this study aims to report our tertiary institution's experience with this uncommon entity. A review of our institution's pathology records for cases of myopericytoma was performed. From January 2009 to September 2020, 23 cases of myopericytoma were identified and their clinicopathologic features were reported. A unique case of myopericytoma of the ankle from the series was also highlighted as a case report. Among the 22 cutaneous cases, 18 were in the extremities and 4 in the head and neck. One patient had an intracranial lesion. Most patients developed asymptomatic nodules (72.2%), but 1 patient had a locally aggressive tumor on presentation. None recurred despite marginal excision in some patients (80.0%). In conclusion, pathologists and surgeons who encounter this rare neoplasm can reassure patients of its benign tendency.

Abstract
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.

Abstract
Myopericytoma is a rare, benign growth characterized by painless lesions with a predilection for the extremities, although they may be found in or on any part of the body. These tumors typically present as a rounded or dome-like non-exophytic lesion and exhibit a benign disease course. Treatment is generally reserved for cosmetic or functional purposes. We present a case of an atypical presentation of an exophytic digital myopericytoma in a 45-year-old female treated with local punch excision.

Abstract
Background Myopericytoma is a rare mesenchymal neoplasm with perivascular myoid differentiation that arises most commonly in middle adulthood. The lesion generally involves the subcutaneous tissue of distal extremities. Myopericytoma of the oral cavity is extremely rare. Herein we report a case of oral myopericytoma in a pediatric patient, who was treated via a conservative approach with a follow up of 8 years. The case is followed by a literature review. To our knowledge this is the first documented case of oral myopericytoma affecting a patient of such a young age.
Case presentation A 6 years old boy was referred to the maxillofacial surgery department for the evaluation of a solitary growth of the right maxillary buccal and palatal gingiva. Histology and immunohistochemistry confirmed the diagnosis of myopericytoma. Conclusions Our patient was treated by local excision with no recurrence in 8 years of follow up. Conservative approach should be considered for the treatment oral myopericytoma especially in young patients in tooth bearing areas.

Abstract
Myopericytoma is a benign tumor with the most common presentation as a well-circumscribed, slow-growing mass. It is frequently misdiagnosed as a sarcoma. We presented a 23-year-old patient with a history of a sciatic pain of the right leg. A careful physical examination discovered tumor-like mass in the posterior part of the thigh. Neurological finding showed a reduction of myotatic reflexes on the right leg with a weaker muscle strength on the right leg. The right leg musculature was slightly hypotrophic in the range of 2-3 cm comparing to left leg. Initially electrophysiological and radiological diagnostic with magnetic resonance imaging (MRI) of the lumbar spine, pelvis and thighs were normal. Magnetic resonance imaging of the right thigh discovered a slow growing 2.1 × 3.8 cm sized mass that was initially described by radiologist as a neurinoma. Patient was admitted to department of neurosurgery and operated on for a tumor removal. Tumor was located intimately to femur and sciatic nerve and after careful dissection completely removed. Patient was doing well after surgery and discharge after three days from the hospital. In the postoperative period the symptoms disappeared. Histopathology showed a myopericitoma. Postoperative MRI after three months of follow up showed no tumor residues, and after 6 and 12 months there was no tumor recurrence. Myopericytoma behave in a benign fashion, but, because local recurrences and rarely metastases may occur in atypical and malignant neoplasms, a careful follow-up after radical resection is recommended.

Abstract
Myopericytoma is a slow-growing, benign soft tissue neoplasm that arises from perivascular smooth muscle cells. This tumor is a rare entity itself, but it is only scarcely mentioned in the literature occurring secondary to trauma. The authors report a 21-year-old male patient who presented with a pulsatile mass in the medial canthal area where he had experienced previous trauma from a car accident 1-year prior. The mass was excised and histopathology revealed myopericytoma. This clinical report adds to the limited body of evidence supporting trauma as an etiology for this rare tumor.

Abstract
A myopericytoma (MP) is an exceedingly rare perivascular tumor of unknown etiology. Given their potential for mimicry and malignancy, MP tumors pose a unique challenge for surgeons and may be overlooked on differential diagnosis. We present a case report of an otherwise healthy 33-year-old right-hand dominant male who presented to our outpatient clinic with a 2-month history of painless swelling and erythema of the pulp of his left index finger. Subsequent plain film X-ray showed near-complete bony destruction of his distal phalanx. Pathological evaluation of an incisional biopsy showed a benign variant of MP. The lesion was treated by excision with tumor shelling, and there was no evidence of recurrence 81 days postoperatively. A systematic literature review of the management and outcome of all known cases of hand and wrist MP is presented.

Herein we report a rare case of a giant myopericytoma presenting in a 16-year-old girl as a slowly progressive swelling involving the scalp in the occipital region. It was managed by complete excision. Histological examination of the lesion revealed spindle-shaped cells forming characteristic rosettes around the blood vessels, and positive staining with smooth muscle actin.
