Single-incision laparoscopic excision of symptomatic accessory spleen in the pelvis: An initial report.

An accessory spleen (AS) is commonly located near the spleen's hilum and/or in the pancreas tail. However, a symptomatic AS is rarely found in the pelvis. We present a resected case with lower abdominal pain whose final diagnosis was symptomatic AS caused by torsion in the pelvis. An 18-year-old man was presented to our hospital with lower abdominal pain. Enhanced abdominal computed tomography showed an inflammatory mass with a cord-like band in the pelvic space. We finally diagnosed pelvic neoplasm and performed single-incision laparoscopic surgery (SILS) using an access platform. SILS of these tumours located on a pelvic lesion has never been reported; this is the first report of torsion of a pelvic AS. SILS for AS is a safe, feasible procedure, even when the AS lays in the pelvic space.
