Sertoli-Leydig cell tumor is a rare sex-cord stromal tumor of the ovary. They make up less than 0.5 % of all ovarian tumors. We experienced a case of an ovarian Sertoli-Leydig cell tumor in a 4 year-old girl who presented with nausea, vomiting, and lower abdominal pain of 2 days' duration. On physical examination, there was mild tenderness in the right lower quadrant of the abdomen. Abdominal ultrasonography and computed tomography (CT) scan revealed a pelvic mass measuring 5 × 3 cm that appeared to arise from the right ovary. At exploratory laparotomy, a 6 × 5 × 3 cm solid right ovarian mass without torsion was found. A right salpingo-oophorectomy was performed. The postoperative course was uneventful. The child was discharged 5 days after surgery.

Wandering spleen is very rare condition in children characterized by migration of the spleen from its normal position due to laxity or absence of the supporting splenic ligaments. We experienced a case of splenic infarction due to torsion of a wandering spleen in a 6-year-old boy who presented with fever, vomiting, and abdominal pain of 2 day's duration. On physical examination, there was severe tenderness in the left upper quadrant of the abdomen. The plain abdominal radiograph showed marked colonic gaseous distension. Contrast-enhanced abdominal computed tomography scan showed decreased density of spleen in the normal position, consistent with infarction. At emergency laparotomy, a wandering spleen twisted 360° on its pedicle was found. Despite splenic detorsion, blood flow could not be restored. Splenectomy was therefore performed. The child was discharged 7 days after surgery without any complications.
