Retroperitoneal lipomatous tumor, characterized by its high proportion of fatty tissue, is a rare condition in the medical literature, with few documented series. Frequently found incidentally through imaging techniques such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET), this tumor can manifest in malignant forms such as liposarcoma. Although liposarcoma is rare, it represents a considerable proportion of retroperitoneal malignancies. Primary adrenal lipomatous tumors, such as liposarcoma and hibernoma, are very unusual and poorly understood clinically. Patients usually present asymptomatic until the tumor grows significantly. Case report: We present the case of a 58-year-old man with intermittent abdominal pain in the right upper quadrant, highlighting the need for better understanding and management of these rare neoplasms. Conclusion: Adrenal lipomatous tumors, although rare and frequently found incidentally, require thorough evaluation and precise management due to their low prevalence and possible malignancy so that timely treatment can be achieved.

El tumor lipomatoso retroperitoneal, que se distingue por su alta proporción de tejido graso, es una condición poco común en la literatura médica, con pocas series documentadas. Frecuentemente hallado de manera incidental a través de técnicas de imagen como ultrasonografía, tomografía computarizada (TC), resonancia magnética (RM) y tomografía por emisión de positrones (PET), este tumor puede manifestarse en formas malignas como el liposarcoma. Aunque el liposarcoma es raro, representa una parte considerable de los tumores malignos retroperitoneales. Los tumores lipomatosos suprarrenales primarios, tales como el liposarcoma y el hibernoma, son muy inusuales y poco comprendidos desde el punto de vista clínico. Los pacientes normalmente no presentan síntomas hasta que el tumor crece significativamente. Caso clínico: Se presenta el caso de un hombre de 58 años con dolor abdominal intermitente en el hipocondrio derecho, subrayando la necesidad de una mayor comprensión y manejo de estas infrecuentes neoplasias. Conclusión: Los tumores lipomatosos suprarrenales, aunque raros y frecuentemente hallados incidentalmente, exigen evaluación exhaustiva y manejo preciso debido a su baja prevalencia y posible malignidad y así se pueda lograr un tratamiento oportuno.
