Autoimmune haemolytic anaemia in pancreatic adenocarcinoma: a potential paraneoplastic presentation

While autoimmune haemolytic anaemia (AIHA) is a well-known paraneoplastic syndrome in haematological malignancies, it has been described far less in solid tumours. We hereby report the case of a 61-year-old male patient presenting AIHA related to pancreatic cancer. Investigations excluded infectious, autoimmune and toxic causes of AIHA. CT of the abdomen highlighted the presence of hypodense, infiltrating mass of the tail of the pancreas measuring 70×37×36 mm, compatible with pancreas neoplasm. Histological examination of two associated nodular lesions of the liver showed metastasis of pancreatic adenocarcinoma. The patient was started on corticosteroid without improvement of haemoglobin. Palliative chemotherapy was initiated; this led to significant improvement in haemoglobin comforting our diagnosis. This case illustrates the rare association between AIHA and pancreatic cancer. However, such association cannot be considered before excluding other, more frequent, aetiologies.
