Omitting histopathology in wrist ganglions. A risky proposition

Objectives: To identify incidence and utility of histopathology in wrist ganglions. Methods: A retrospective study of 112 patients operated for wrist swellings between January 2009 and March 2014 at Aga Khan University Hospital, Karachi, Pakistan, was conducted. Medical records were reviewed for demographics, history, location and associated symptoms, provisional diagnosis and operative details. Histopathology reports were reviewed to confirm the final diagnosis. Results: One hundred and twelve patients were included in the study (34 males and 78 females) with a mean age of 28 ± 12 years. Ninety-five percent of ganglia were dorsally located and 85% were solitary in nature. Histopathology reports confirmed 107 as ganglion cysts, whereas 3 had giant cell tumor of tendon sheath and 2 were reported to be tuberculous tenosynovitis. Conclusion: Although most of the time, the clinical diagnosis conforms to the final diagnosis, the possibility of an alternate diagnosis cannot be ignored (4% in this study). We suggest routine histopathological analysis so that such diagnoses are not missed.
