RESUMO
BACKGROUND/AIM: Inflammatory myofibroblastic tumors (IMTs) are rare, solid, potentially malignant lesions of uncertain etiology. Histologically, IMTs exhibit a combination of lymphocytes and inflammatory cells within a fibroblastic myxoid layer. The diagnosis of IMTs poses a challenge for various medical specialties, including surgeons, pathologists, and oncologists, due to their non-specific clinical presentation. Furthermore, radiologists face difficulties in interpreting computed tomography (CT) or magnetic resonance imaging (MRI) results, which often yield polymorphic and inconclusive findings. Ultimately, histopathologists play a crucial role in reaching a definitive diagnosis based on the tumor's histological characteristics. They are detected in every system of the human body, most commonly in the lungs. Here, we report an uncommon occurrence of IMT in the spleen of a patient with nonspecific abdominal pain. CASE REPORT: A 56-year-old Caucasian female presented to Konstantopouleio General Hospital of Nea Ionia, Athens, Greece, with abdominal pain and discomfort. The patient had no significant medical history and normal laboratory tests. An abdominal CT revealed a large mass in the spleen. A splenectomy was performed. Histopathological analysis of the tumor revealed IMTS. CONCLUSION: Splenic IMT is a rare benign tumor with moderate malignant potential. It lacks a distinct clinical presentation and is typically identified either incidentally or during the examination of abdominal pain.
