Autoimmune haemolytic anaemia as the presenting manifestation of agnogenic myeloid metaplasia

We report an unusual case of a 40-year-old female patient with a severe case of direct Coombs positive haemolytic anaemia, moderate hepatomegaly and marked splenomegaly. Her initial response to steroids was transient and was rapidly followed by a relapse. Therefore, she underwent splenectomy both as a therapeutic measure and to rule out an underlying lymphoproliferative disorder. Histopathological examination of the excised spleen, as well a liver biopsy, revealed extensive extramedullary haematopoiesis, while significant marrow fibrosis was noted in a trephine biopsy sample. These findings confirmed the concomitant diagnosis of agnogenic myeloid metaplasia with myelofibrosis.
