An Unusual Case of Tuberculous Tenosynovitis of the Hand.

Infectious tuberculous tenosynovitis (TS) is an unusual occurrence in the forearm, wrist, or hand. Here we report a case of tuberculous TS of the wrist in a 26-year-old male with no comorbidities. The patient presented with a nonhealing ulcer on the palmar aspect of the proximal part of the left little finger with restricted mobility. There were no other symptoms to confirm the existence of an active tuberculosis infection in this patient. This case report helps broaden our knowledge about the different presentations of tuberculous TS in a patient with no history of exposure to tuberculosis.
