Pelvic alveolar rhabdomyosarcoma in a young adult.

Rhabdomyosarcomas are soft-tissue tumors, rare in adults. Accounting for nearly 5% of childhood cancers, they represent less than 0.03% of adult malignancies (1, 2). Three different subtypes of rhabdomyosarcoma have been described (embryonal, alveolar and pleomorphic), making up approximately 50%, 30%, and 20% of the cases, respectively (3). Although the definitive diagnosis is made pathologically, some distinguishing features among these subtypes, and between rhabdomyosarcomas and other soft-tissue tumors, can be suggested on MRI and CT. We present an interesting case of a 20-year-old female with a locally aggressive pelvic alveolar rhabdomyosarcoma. While the prognosis has improved with newer treatment techniques, overall survival rates remain poor. Our case study presents typical features of a rare disease, which can often present a diagnostic dilemma for clinicians.

Intraperitoneal catheter drainage of lymphocele: an outpatient procedure.

Laparoscopic marsupialization of lymphocele carries 13% recurrence rate, 6% injury to other organs, 12% omentoplasty, 6% open conversion and 1.8 average hospital days. A novel, simplified technique of intraperitoneal catheter drainage of lymphocele is described. Under ultrasound guidance and using the Seldinger technique, a 13F Hickman catheter was introduced into the lymphocele and connected subcutaneously to a small peritoneal window performed 5 cm apart. During the last 8 years the procedure was performed under local anesthesia in 14 patients on an outpatient basis with success (e.g. resolution of both hydronephrosis and lymphocele). One wound infection required removal of the catheter without recurrence. In another patient laparoscopy showed retraction of the catheter under the peritoneum as cause for lymphocele recurrence. In all cases absence of injury to the GU tract was confirmed by absence of extravasation of indigo carmine given intravenously. Intraperitoneal catheter drainage of post-transplant lymphocele is an effective outpatient procedure. It avoids the drawbacks of general anesthesia required by open and laparoscopic marsupialization procedures and deserves to be evaluated in a multicenter study.
