Intramuscular lymphoma: uncommon presentation of Hodgkin's disease.

Extranodal presentation in lymphoproliferative disorders is a well-recognised entity. However, musculoskeletal involvement is extremely rare. We describe the case of a 64-year-old farmer who presented to us with constitutional symptoms of fever, loss of weight and loss of appetite for 2 years and physical examination revealing generalised lymphadenopathy with hepatosplenomegaly. Biopsy of an axillary lymph node showed mixed cellularity variant of Hodgkin's lymphoma. CT of the thorax and abdomen revealed a collection in the right psoas muscle. Guided biopsy of the psoas deposit was suggestive of Hodgkin's lymphoma. PCR and cultures for Mycobacterium tuberculosis tested negative. Here we describe a rare presentation of Hodgkin's lymphoma with intramuscular involvement. © BMJ Publishing Group Limited 2020. No commercial re-use. See rights and permissions. Published by BMJ.
