Fatal diarrhea in a patient with Castleman's disease associated with intestinal amyloidosis

A 32-year-old woman presented with Castleman's disease associated with intestinal amyloidosis. The association of amyloidosis and Castleman's disease is very rare, with only 15 cases reported in the literature. To our knowledge, this is the second case in which persistent diarrhea and malnutrition led to the patient's death.
