Abstract
Myopericytoma is a rare tumour which typically presents as a benign lesion that mimics features of other more common vascular tumours and malformations. We present a case of a symptomatic diffuse myopericytomatosis of the left abdomen presenting as multiple subcutaneous vascular tumours detected on ultrasound and treated with ultrasound-guided sclerotherapy.

Abstract
Myopericytoma is a rare vessel wall tumor, a subtype of hemangiopericytoma that usually develops subcutaneously. Intravascular myopericytoma is a rarer subtype, with only few cases reported in the literature and even fewer with imaging modalities included. We report the case of a 36-year-old man who was referred to our institution with a painless, palpable mass in the right arm and was evaluated with MRI, grey-scale and Doppler-mode ultrasound. Tumor histopathology and imaging characteristics are presented together with the role that each imaging modality played in the management of the patient.

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
Background Testicular embryonic rhabdomyosarcoma (ERMS) is a rare soft tissue tumor in children featured with high intra-tumoral heterogeneity. In this study, we aimed to comprehensively delineate the testicular ERMS intra-tumoral heterogeneity and tumor microenvironment. Methods Cell types and the corresponding marker genes were identified by single-nuclear RNA sequencing (snRNA-seq). Functional states of different clusters were evaluated by uniform manifold approximation and projection and differentially expressed genes. Kaplan–Meier curve analysis was constructed according to the gene expression profile to determine the correlation between candidate marker genes and the overall survival and disease-free survival of patients with osteosarcoma from TCGA. Results A total of 8868 tumor cells and 10,147 normal cells were obtained from testicular ERMS tissues. The heterogeneous malignant subtype was composed of six subgroups (C1–C6) with differential proliferative and migratory potentials. Cell trajectory analysis revealed the C1 subgroup might be the starting cells of the tumor and transform into two different types of malignant cells, C2 and C5/6, during the development of RMS. The differentially expressed genes were closely related to cell adhesion and extracellular matrix signaling pathways. Furthermore, the interaction analysis between cell subgroups (macrophages and tumor cells, endothelial cells and tumor cells) demonstrated that collagen-related gene COL6A1 plays a key role from the initiation of ERMS to the entire process of malignant transformation. Conclusion Our findings provide a new insight in the understanding of the initiation and progression of testicular ERMS and have potential value in the development of markers for the diagnosis and stratification of testicular ERMS.

Abstract
Introduction and importance Myopericytoma (MPC) is a rare benign soft tissue neoplasm that arises from perivascular smooth muscle-like myoid cells that share features of both glomus and smooth muscle cells. It usually slow growing solitary tumor that might mimic aggressive sarcoma. Case presentation 45 years old male, with unremarkable medical history, presented with fast growing mass on the left 1st webspace that was noticed 6 months prior to presentation. Investigations with US and MRI showed highly vascular solid mass that was worrisome for malignant lesion. Surgical excision was done and histopathology confirmed the diagnosis of myopericytoma. Clinical discussion MPC is a rare perivascular neoplasm that’s reported mainly in the extremities with lower limbs are most affected sites. Usually it presents as solid painless slowly growing mass. However, Multiple papers reported different rare presentations like multiple, painful and some with malignant transformation. Conclusion MPC is a benign tumor that might mimic aggressive sarcoma. Such cases should be approached with high suspicion and proper investigation and management should be followed promptly. Myopericytoma (MPC) is a rare benign soft tissue neoplasm.

Abstract
INTRODUCTION Myopericytoma is a rare mesenchymal soft tissue tumor that originates from perivascular myoid cells and mostly benign in nature. With a slight male predisposition, it occurs more commonly in the lower extremities with an insidious and painless presentation. Contrary to the usual, our patient was with a rare presentation in the inguinal region with a dull aching pain. CASE PRESENTATION We herein report a case of a 64-year-old female patient with myopericytoma, the first of its kind reported in Nepal, present in the right inguinal region and surgically removed. The mass was single with dull aching pain, non-tender, globular, smooth, mobile, covered with skin and, had been slowly growing for 1 year and had started bleeding for 4 days. On complete surgical excision and subsequent biopsy, a nodule with thin-walled blood vessels and spindle-shaped cells having indistinct cell border, eosinophilic cytoplasm, and oval to spindle-shaped nucleus was observed, features consistent with those of myopericytoma. DISCUSSION Myopericytoma can occur in different sites in the body. Its differential diagnoses in the inguinal region include inguinal hernia, lipoma, or an inguinal lymphangioma. Histopathological analysis and immunohistochemistry (IHC) staining are used for diagnosis and confirmation. CONCLUSION Myopericytomas are rare and have a substantial propensity to be misdiagnosed as other soft tissue tumors such as sarcomas due to significant overlap in their presentation and histological features. Complete surgical excision of mass is the curative therapy.
