Isolated tubercular tenosynovitis is a rare entity, and is extremely rare in children. Seven cases of isolated tubercular tenosynovitis are presented, all in children in their second decade of life. There were no primary detectable lesions elsewhere in the body. Diagnosis in all the cases was obtained by fine-needle aspiration cytology. All patients were treated by antitubercular drugs for 18 months and achieved complete healing and full function. Use of fine-needle aspiration cytology in tubercular tenosynovitis is discussed.
