Background: The aim of this report is related to adult primary paratesticular mesenchymal tumors with emphasis on a case presentation and discussion of the spermatic cord leiomyosarcoma. Primary paratesticular tumors are rare, only accounting for 7% to 10% of all intrascrotal tumors. In adults, more than 75% of these lesions arise from the spermatic cord, 20% being leiomyosarcoma. Tumor grade, stage, histologic type, and lymph node involvement are independently predictive of prognosis. Findings: The case report concerns a 81-year-old man presented with a 3-year history of painless lump in the right hemiscrotum. Scrotal examination demonstrated a 5.1-cm, firm-to-hard mass attached to the spermatic cord. Scrotal ultrasound scan revealed a heterogeneous mass separate from the testis. He was treated with an radical orchi-funicolectomy. Histologically the lesion is composed of spindled cells with often elongated, blunt-ended nuclei and variably eosinophilic cytoplasm. Areas with pleomorphic morphology are present. The level of mitotic activity is equal to 3/10 HPF in the areas with spindle cell morphology and to 12/10 HPF in the areas with pleomorphic morphology. The final diagnosis was that a leiomyosarcoma of the spermatic cord, with grade 1 and grade 2 areas, stage pT2b cN0 and cM0. The patient has been followed up for 3 months with CT scans and shows no signs of recurrence. Conclusions: Spermatic cord leiomyosarcoma, although rare, should be one of the first differential diagnoses for a firm-to-hard lump in the cord. Apart from radical orchi-funicolectomy, there has been added benefit of adjuvant radiotherapy to prevent any loco-regional lymph node recurrence
