Liposarcoma of the paratesticular tissue and spermatic cord: A case report

Abstract

Introduction. Liposarcomas are malignant tumors derived from fat tissues. Liposarcoma of the paratesticular tissue is rare. Case report. We presented a 51-year-old man with liposarcoma of paratesticular tissue and the spermatic cord, mimicking a testicular tumor. Ultrasound examination of this scrotal mass was hyperechogenic and homogeneous and separated from the testis and epididymis. The patient was operated, and the orchidectomy was performed. Histology revealed well-differentiated lipoma-like liposarcoma of the paratesticular tissue and spermatic cord. After a 6 month follow-up the patient did not show any evidence of tumor-progression or recurrence. Conclusion. Liposarcomas of the paratesticular tissue and seminal cord represent a rare type of tumors, often misdiagnosed preoperatively. Therapy should include radical surgical excision, usually radical inguinal orchiectomy. If the margin status is in doubt, adjuvant radiation should be performed. Local relapse is common and may occur after several years, so follow- up period has to be sufficiently long.Uvod. Liposarkom je maligni tumor koji nastaje iz masnog tkiva. Paratestikularni liposarkom se rijetko javlja. Prikaz bolesnika. U radu je prikazan bolesnik, star 52 godine, sa liposarkomom koji je bio lociran paratestikularno i u tkivu funikulusa, sa klinickom slikom nalik tumoru testisa. Ultrazvucno, tumorsko tkivo bilo je hiperehogeno, nehomogeno i odvojeno od testisa i epididimisa. Kod bolesnika je uradjena operacija orhiektomije. Histoloski, nadjeno je tkivo dobro diferentovanog lipoma-like liposarkoma u dijelu paratestikularnog tkiva i tkiva oko funikulusa. Nakon pracenja tokom 6 mjeseci nijesu uoceni znaci progresije tumora niti recidiva. Zakljucak. Liposarkomi koji zahvataju paratestikularno tkivo i funikulus su rijetki i obicno se preoperativno pogresno dijagnostikuju. Terapija podrazumijeva radikalnu hirursku eksciziju, najcesce radikalnu ingvinalnu orhiektomiju. Ukoliko postoji sumnja o statusu ivica resekcije, potrebno je primijeniti adjuvantnu radioterapiju. Lokalni relapsi su cesti i mogu se javiti i nakon vise godina, pa je potrebno dugogodisnje pracenje ovih bolesnika.
