Mantle Cell Lymphoma With Non-traumatic Splenic Rupture Requiring Emergency Splenectomy.

Mantle cell lymphoma (MCL) is a type of non-Hodgkin (B-cell) lymphoma (NHL) with manifestations ranging from indolent to aggressive disease. This type of NHL is predominately found in western countries and affects men more often than women (M:F 2:1). The median age of diagnosis with the disease is around 60 years of age. In this report, the patient is a 68-year-old female who had an atraumatic splenic rupture with no past medical history of trauma. She presented to the emergency department with severe abdominal pain in her left upper quadrant. An emergency splenectomy was executed successfully, and the patient was stabilized. In this case report, we will discuss the pathogenesis, clinical presentation, known clinical treatment, diagnostic testing, and atraumatic splenic rupture.
