Hypocalcemia Revealing an Enteropathy-Associated T-cell Lymphoma

Background: enteropathy-associated t-cell lymphoma (eatl) is a rare and aggressive type of extranodal t-cell lymphoma (tcl) arising in the gastrointestinal (gi) tract and represents 5–8% of all t-cell non-hodgkin lymphomas (nhl) and 10–25% of primary intestinal lymphomas. case presentation: we reported a 78-year-old woman presenting with severe hypocalcemia. investigations confirmed vitamin d and iron deficiency as well as hypoalbuminemia. celiac disease was suspected and confirmed, but despite intravenous calcium and magnesium supplementation and a gluten-free diet, normal electrolyte levels were never reached. intestinal perforation was the clue to the diagnosis of enteropathy-associated t-cell lymphoma (eatl). conclusion: hypocalcemia can result from multiple conditions. in patients not responding to adequate supplementation, further investigations should be performed to diagnose the underlying condition
