Introduction:
Liposarcoma is a malignant neoplasm of the adipose tissue, and dedifferentiated liposarcoma is a relatively rare subtype. Liposarcomas are typically located in the lower extremities or retroperitoneum, but dedifferentiated liposarcoma of the spermatic cord is rare and no case of it with macroscopic ossification has been reported in the literature.
Case Presentation:
A male presented to our hospital with a painful, palpable, and hard left suprapubic mass, formed over 3 months. The mass was diagnosed as a spermatic cord tumor and was resected using high orchiectomy. Due to the histological diagnosis of dedifferentiated spermatic cord liposarcoma with ossification and positive margins, a second extended resection and adjuvant radiotherapy were performed.
Conclusion:
To differentiate spermatic cord liposarcoma preoperatively is difficult. There is no gold standard treatment for it, although surgical complete resection with clear microscopic margins would be the most effective treatment.
