title: Large Ganglion Cyst with Unusual Location on the Back-A Case Report.
abstract: A ganglion cyst is a soft tissue tumor-like lesion filled with colloid material commonly located on the hand and wrist. We report a case of a large ganglion cyst with an unusual location on the back. The patient presented with a mass growing over 2 months measuring 11.2 × 4.7 × 7.2 cm on magnetic resonance imaging. Ultrasound and puncture was attempted twice without achieving drainage. After surgical removal, histologic examination diagnosed the tumor as a ganglion cyst. We conclude that when evaluating a subcutaneous soft tissue mass, regardless of localization, a ganglion cyst may be a differential diagnosis.
