Cystic lymphangioma is a very rare condition of unknown etiology. It is generally regarded as a developmental malformation in which obstruction or agenesis of lymphatic tissue results in lymphagi-ectasis secondary to lack of normal communication of the lymphatic system.

Most lymphagiomas occur in the neck(75%) and axillary region(20%). Lymphagiomas may rarely occur in the retroperitoneum, mediastinum and mesentery.

We report a case of 42-year-old woman with histologically proven cystic lymphagioma retroperitoneum.

Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood and 20 percent of Rhabdomyosarcoma in children arise in the urogenital. The paratesticular rhabdomyo-sarcoma is a highly malignant neoplasm with early invasion and metastases, which has retroperitoneal metastases in about half of the patient at time of dignosis. However, the survival rates have been improved greatly by using multimoaltherapy.

We report a case of paratesticular rhabdomyosarcoma with brief review of the literatures.

Malignant fibrous histiocytoma(MFH) is the most common soft tissue sarcoma of late adultlife, majority of cases occuring in persons between ages of 50 and 70.

It occurs most frequently on the lower extremity followed by upper extremity and retroperitoneum.

Primary involvement of the kidney is quite rare, with only 19 cases reported in the literature.

We report a case of 74-year-old woman with histologically proven MFH of the right kidney.
