BackgroundMost cases of disseminated carcinomatosis of the bone marrow (DCBM) arise from gastric cancer. DCBM from pancreatic cancer is very rare. We herein present a case of DCBM from pancreatic cancer.Case presentationA 57-year-old man was referred to our hospital for severe lumbago. Laboratory data indicated that he suffered from disseminated intravascular coagulation (DIC). Non-contrast abdominal computed tomography (CT) revealed multiple bone masses but no other abnormal findings. Left iliac bone marrow biopsy revealed poorly differentiated adenocarcinoma cells. Positron emission tomography (PET)-CT showed diffuse abnormal uptake in the bones and tail of the pancreas. Contrast whole-body CT showed a tumor measuring approximately 28 mm in diameter with poor enhancement in the tail of the pancreas. The patient’s final diagnosis was pancreatic cancer located in the tail of the pancreas with diffuse bone metastases and DIC. His DCBM was thus believed to originate from the pancreatic cancer. He succumbed to the disease approximately 2 months after admission to our hospital.ConclusionWe herein describe a case of pancreatic cancer located in the tail of the pancreas with diffuse bone metastases and DIC, which, in our case, was DCBM. Therefore, in cases of DCBM with an unknown primary tumor, pancreatic cancer should be considered during differential diagnosis.

We herein report a case of Addison's disease caused by tuberculosis characterized by atypical hyperpigmentation, noted as exacerbation of the pigmentation of freckles and the occurrence of new freckles, that was diagnosed in the presence of active pulmonary tuberculosis. The clinical condition of the patient was markedly ameliorated by the administration of hydrocortisone and anti-tuberculosis agents. When exacerbation of the pigmentation of the freckles and/or the occurrence of new freckles are noted, Addison's disease should be considered as part of the differential diagnosis. In addition, the presence of active tuberculosis needs to be assumed whenever we treat patients with Addison's disease caused by tuberculosis, despite its rarity.
