Disseminated fat necrosis with asymptomatic pancreatitis: A case report and review of the literature

A 62-year-old man with multiple nontender skin nodules is presented. Some of these nodules discharged a purulent looking fluid. At presentation, the patient did not have any other complaints. No infectious, neoplastic, or immunologic origin could be found for the nodular rash. Biochemical profile, imaging, and skin biopsy confirmed the diagnosis of disseminated fat necrosis (DFN) accompanying asymptomatic pancreatitis. The process involved the mesenteric, subcutaneous, and intramedullary fat. The skin lesions were surgically treated. Mesenteric and intramedullary fat necrosis were watched closely. A year later, the patient was readmitted with a diagnosis of pancreatitis. Subcutaneous and intramedullary necrosis were completely resolved at this time, and only mesenteric fat necrosis prevailed. The clinical syndrome of DFN, its etiology, pathophysiology, treatment, and prognosis are discussed.
