Myeloid Sarcoma Presenting As Obstructive Jaundice

Myeloid sarcoma (MS) is a rare solid neoplasm that consists of extramedullary myeloid precursor cells. Generally, it is associated with underlying acute myeloid leukemia (AML) or AML yet to manifest clinically. It can present as isolated, also known as primary MS without evidence of AML or other myeloproliferative neoplasms. We present the case of a previously healthy 36-year-old male, who was admitted to hospital with new-onset painful obstructive jaundice and final diagnosis of isolated MS was made after through investigations. We are pleased to report that he had favorable response to the treatment and remains well.
