Unraveling Anastomosing Hemangioma: A Case Report.

Anastomosing hemangioma is a rare and benign subtype of capillary hemangioma, a soft tissue tumor. It tends to be asymptomatic, causes abdominal pain and hematuria, and is more common in the genitourinary tract. It can be confused with paragangliomas or ectopic pheochromocytomas. Pathology shares characteristics with angiosarcoma, particularly in well-differentiated areas. Diagnosis without a surgical specimen is difficult and is based on clinical characteristics, laboratories, and imaging behavior similar to hemangiomas in other locations. When in doubt, a diagnosis can be supported by a percutaneous biopsy. The prognosis is good, without relapses or metastases. Early identification with follow-up can avoid surgical interventions.
