The image shows intraoperative photograph of a ganglion cyst attached to the flexor tendon sheath of the middle finger. The patient was a 31 y/o male who presented with swelling on the palmer aspect of his right wrist. The swelling was cystic and fluctuant and freely moved with the flexion/extension of the right middle finger. Microscopically, it was a cystic lesion lined by connective tissue composed of bland spindle shaped cells in myxoid matrix. Epithelial or synovial lining was not seen. Ganglia (Ganglion cysts) arise by myxoid degeneration and softening of the connective tissues of the joint capsule or tendon sheath. Case contributed by: Dr. Madhav S. Khadilkar and Dr. Sanjay D. Deshmukh, Smt. Kashibai Navale Medical College, Pune, India.
