Huge renal oncocytoma with solid and cystic areas - A case report and review of literature

This abstract presents a rare case of a huge renal oncocytoma, emphasizing its diagnostic challenges, clinical management, and unique characteristics. Oncocytomas are relatively uncommon benign neoplasms, typically found in various organs, including the kidneys, salivary glands, and thyroid. However, the occurrence of an exceptionally large renal oncocytoma poses distinct clinical considerations. We report the case of a patient who presented with a large palpable mass occupying almost whole abdomen with firm to hard in consistency. The diagnostic process involved an imaging studies, including computed tomography (CT) along with histopathological examination of specimen. The diagnostic challenges stemmed from the atypical size and radiological features. Surgical intervention was necessary due to the size of the renal oncocytoma. This case highlights the importance of considering renal oncocytomas in the differential diagnosis of large renal masses, even when their size exceeds typical dimensions. The management of huge oncocytomas involves a multidisciplinary approach, incorporating advanced imaging techniques, pathological assessment, and surgical expertise. Histology of renal oncocytoma in our case is also different as it is showing cystic areas. Immunohistochemistry confirmed the diagnosis of renal oncocytoma. Awareness of these rare cases is crucial for clinicians to guide appropriate diagnostic and therapeutic strategies, ensuring optimal patient outcomes.
