Paratesticular dedifferentiated liposarcoma with rhabdomyosarcomatous differentiation presenting as hydrocele in an older man: a case report

This case emphasizes the rarity and highlights the importance of clinicopathological features, diagnostic pitfalls, and prognostic implications considering PTDDLPS with rhabdomyosarcomatous differentiation, reinforces the oncologic importance of a high inguinal approach for suspected malignant paratesticular masses in older men. IHC and molecular analyses are crucial for an accurate diagnosis, particularly in tumors with heterologous elements that may mimic other sarcomas or germ cell tumors. Early recognition and multidisciplinary management optimize local control and surveillance planning.
