We present a case of an elderly male with a six-month history of painless, progressively increasing left inguinal swelling. On preliminary examination and investigation, the swelling was misdiagnosed as a lymph nodal mass. Subsequently, a magnetic resonance imaging study detected a lesion that was not distinct from the spermatic cord. Biopsy testing of the said lesion was suggestive of poorly differentiated spindle cell neoplasm. The patient then underwent a high inguinal orchidectomy. Histopathological examination confirmed the diagnosis of a high-grade paratesticular dedifferentiated liposarcoma with rhabdomyoblastic differentiation. Due to the rarity of such tumours, the need for adjuvant chemotherapy and radiotherapy is debated.
