We present a case of a 28âyearâold male who presented with acute abdomen and was later diagnosed to be having ruptured intraâabdominal seminoma with hemoperitoneum, where the preâoperative diagnosis was not made. Laprotomy and complete excision were carried out. Rupture of intraâabdominal testicular seminoma is a rare cause of acute abdomen and hemoperitoneum. The preâoperative diagnosis is often difficult because history of cryptorchidism is not provided and imaging findings may be nonâspecific. In a male patient with acute abdomen and without previous history of orchidectomy, a testicular aetiology of acute abdomen should be kept as the differential diagnosis.
