An Unusual Presentation of Extrapulmonary Tuberculosis in a Fibrocalculous Pancreatic Diabetes Patient.

Fibrocalculous pancreatic diabetes (FCPD) mellitus is a distinct type of diabetes that arises from chronic calcification of the pancreas in young, nonalcoholic individuals, predominantly in tropical regions. The characteristic triad of FCPD includes diabetes, abdominal pain, and steatorrhea. Additional notable features of the disease are its early age of onset, the presence of large intraductal stones, rapid disease progression, and a heightened risk of developing pancreatic cancer. Tuberculosis (TB) is a health concern worldwide and is responsible for a major health burden in developing countries like India. TB involving any organ other than the lungs is diagnosed as extrapulmonary tuberculosis (EPTB). EPTB with musculoskeletal involvement is often a difficult and delayed diagnosis because of unusual clinical presentations.
