Recurrent Scrotal Arteriovenous Malformation as a Slowly Increasing Left Testicular Swelling: A case report.

Arteriovenous malformations (AVMs) are benign vascular lesions. Although, the majority of AVMs occur in the central nervous system, there are published reports of AVMs involving all systems including the scrotum, kidney, and uterus. We report a 37-year-old male patient who presented to the urology clinic of a tertiary care hospital in Riyadh, Saudi Arabia, in 2021 with recurrent gradual scrotal swelling for four years attributed to scrotal AVM. Embolisation was performed; however, one year later his symptoms reoccurred. As a result, left partial scrotal wall excision was carried out without complications.

Fast growing myopericytoma of the hand: Case report and literature review.

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.
