We have read the interesting paper recently published by Ali et al., March, 8 volume, 1 issue, detailing a case of pancreatic mass in a 40-year-old male presenting with important weight loss, abdominal pain, and fever for 2 weeks. He denied any other complaint, history of tuberculosis, or drugs assumption.
Recently, we have observed a comparable case of pancreatic tuberculosis which in our opinion deserves a short mention, given the rarity of such presentation and the entailed diagnostic clinical and pathologic challenges, especially when dealing with patients coming from endemic areas for tuberculosis.
As Ali et al. properly stressed, despite the high prevalence of tuberculosis in developing countries, a preponderant or exclusive presentation as a pancreatic mass in advanced disease is rather uncommon and cases published in the pertinent literature are limited.,
We herein describe of a 30-year-old man from Ivory Coast who has been recently referred to our Hospital complaining of abdominal pain and lack of appetite; he was treated with imatinib for chronic myeloid leukemia about 1 year before. In addition, the past medical history was positive for pulmonary tuberculosis diagnosed and treated 7 years previously. On admission, physical examination was negative for enlarged superficial lymph nodes. He denied weight loss and did not present jaundice. Abdominal ultrasound revealed a slightly enlarged spleen, and computed tomography scan revealed a 1.6 cm solid mass within the pancreatic head [Figure 1]a along to enlarged lymph nodes at the hepatic hilum and celiac tripod. A chest X-ray evidenced pleural effusion. Serum level of carcinoembryonic antigen and CA19.9, as well as pancreatic hormones were negative and routine exams showed leukopenia. His QuantiFERON was positive, but the bronchoalveolar washing was negative. The clinical differential diagnoses favored either a pancreatic localization of chronic myeloid leukemia or a primitive pancreatic neoplasia; hence, a fine-needle aspiration cytology (FNAC) of the mass was performed. The aspirated material was examined by means of the cell-block technique, and microscopic examination of hematoxylin-eosin stained sections showed fibrinoid material, Langhans giant cells, and scattered inflammatory cells [Figure 1]b. Atypical epithelial cells were not recognized, so ductal carcinoma was reasonably excluded. All the other histochemical and immunohistochemical stains were negative. On the overall, the combined microscopic evidence were deemed consistent with pancreatic localization of tuberculosis, and after appropriate therapy, the patient does not report any relapse.

Although rarely diagnosed,, approximately 15%–20% of tuberculosis cases worldwide are extrapulmonary forms and patients may or may not have had active pulmonary disease or history of tuberculosis.
Along to the considerations addressed by Ali et al. in their index paper, we emphasize once again that pancreatic tuberculosis should be considered in the differential diagnosis of a solid pancreatic mass, especially in patients with a history of tuberculosis or in subjects coming from geographic areas where tuberculosis is endemic. Instrumental guided FNAC or biopsy proven useful diagnostic tools especially either in oligo/asymptomatic  patients with nonspecific clinical features.
