Delayed Traumatic Rupture of the Spleen in a Patient with Mantle Cell Non-Hodgkin Lymphoma after an In-Hospital Fall: A Fatal Case.

Splenic rupture and hematoma are significant complications that can occur in patients with non-Hodgkin lymphoma (NHL). Understanding these associated complications is essential for optimal patient management and enhanced patient outcomes. Histopathological and immunohistochemical analyses are crucial in diagnosing NHL and assessing splenic involvement. In this study, a judicial autopsy had been requested by the Prosecutor's Office for a malpractice claim due to a fall in the hospital. In the Emergency Department, a 72-year-old man fell from a gurney and reported sustaining a wound to his forehead. No other symptoms were reported. A face and brain CT scan showed no abnormalities. Nine days after discharge, the patient presented with abdominal pain. An abdominal CT revealed splenic rupture and hemoperitoneum. The patient underwent open splenectomy but showed signs of hemodynamic shock and subsequently died. The evidence from the autopsy allowed us to diagnose mantle cell non-Hodgkin lymphoma with spleen involvement, previously unknown. Histopathological and immunohistochemical analyses were performed to assess the diagnosis of splenic rupture and estimate its timing. The findings strongly suggest that the splenic rupture was associated with the patient's fall and the pre-existing malignancy. This case highlights the importance of considering an underlying hematological malignancy when investigating delayed splenic rupture. An immunohistochemical study of spleen samples allowed the timing of splenic hematoma and rupture to be assessed, leading to the establishment of a causal relationship with trauma.
