Amyloidosis is a group of disease that is characterized by the deposition of extracellular abnormal proteinaceous material (amyloid), in various organs. Amyloidosis involving the liver is common, and the radiological findings are often nonspecific. We present the case of a 40-year-old female who presented with abdominal pain. Ultrasound abdomen was reported as massive hepatomegaly with diffuse liver parenchymal disease. Bone marrow aspiration showed normomegaloblastic erythroid hyperplasia and plasma cells were within normal limits (5%). Also, amorphous, eosinophilic fragmented to smudgy material within the interstitium of cell trails was seen. Bone marrow biopsy and liver biopsy also showed similar kind of homogenous eosinophilic material. Both liver biopsy and bone marrow biopsy were subjected to special stains which confirmed the presence of amyloid. The patient did not have clinical or laboratory findings suggestive of any other organ involvement. Thus, we conclude that clinical and imaging presentations of amyloidosis are often nonspecific, hence biopsy is always required to confirm the diagnosis. Amyloid deposits on bone marrow aspiration are a rare occurrence and are often missed. It is an unusual sighting with very few studies mentioning its occurrence.
