    Paratesticular liposarcoma: ultrasonography findings
    (2017) Koc, Mustafa; Ozercan, Resat
    Genitourinary system sarcomas constitute 1-2% of all urological tumors. Paratesticular liposarcoma a very rare tumor accounts for 3-7% of paratesticular sarcomas. In this article, we presented a 67 year-old patient with a painless mass-swelling in the left testicular region for about 1 year. Imaging findings revealed a large heterogeneous mass in the left scrotal sac observed with a lobulated contour and hyperechogenic areas, approximately 74x34 mm in size, no test planes with testis, epididymis and spermatic cord. The mass was treated with orchiectomy. Histopathological evaluation of the tumor was reported as pleomorphic liposarcoma with paratesticular placement. We decided to present a rare case with ultrasonography (US) and Doppler US findings.

    Primary hand rhabdomyosarcoma: A rare case report
    (2017) Koc, Mustafa; Ozercan, Resat
    Rhabdomyosarcomas are malignant, soft tissue tumors with striated muscle origin. Malignant round cell tumors are the common malignancy of childhood. The primary localizations are head and neck and genitourinary system. Only 7 % of lesion is seen in the upper extremity. Primer hand involvement is rare. In this article, we presented a 16-year-old girl who admitted to our clinic with a complaint of a painful mass that grew rapidly in the left hand thenar area. Imaging findings revealed a heterogeneous solid mass lesion between the 1st and 2nd fingers, which showed dense contrast enhancement, approximately 6x5x7 cm in size, leading to destruction in the bony structures. A histopathological examination of the mass indicated alveolar rhabdomyosarcoma. We decided to present this rare entity with the radiological imaging findings.
