A Rare Case of Partial Small Bowel Obstruction Secondary to Intestinal Myeloid Sarcoma

Abstract

This case report details a rare case of small bowel myeloid sarcoma (MS) in an otherwise fit and well 49-year-old male presenting initially with vague obstructive symptoms and weight loss. The patient ultimately required an operation for a small bowel obstruction where a laparotomy and small bowel resection were performed due to three cicatrising completely obstructing lesions in the mid-jejunum. Fewer than 1% of patients with acute myeloid leukaemia (AML) present with MS as an initial diagnosis, and only 6.5% of these are intestinal in origin. This report adds to the current body of literature on this rare condition, emphasises the diagnostic challenges resulting in delays to diagnosis, and discusses the crucial role of early and accurate identification for optimal treatment and prognosis. Surgery may be warranted in patients with complications such as obstruction; however, systemic chemotherapy tailored to AML is the primary therapeutic approach for MS patients.
