Scrotal hemangioma misdiagnosed as a malignant tumor in Klippel-Trénaunay syndrome: A case report and review of the literature

The paper discusses a challenging medical case of a 29-year-old male patient who was diagnosed with a scrotal hemangioma in association with Klippel-Trénaunay syndrome (KTS). In this case, the patient experienced an increase in size and pain in the right scrotum, which was initially suspected to be a malignant tumor of the right testis based on B-ultrasound and magnetic resonance imaging findings. This case is particularly rare and notable because KTS involvement in the scrotum is uncommon in clinical practice, complicating the diagnostic process. The patient had a history of surgical intervention for KTS, which included high ligation of the right great saphenous vein. The case underscores the importance of clinicians being aware of the clinical features of KTS to ensure accurate diagnosis and appropriate management when presented with similar scrotal symptoms. This report serves to highlight the diagnostic challenges and considerations necessary in cases where symptoms may mimic those of more common conditions, such as testicular tumors.
