[Extraskeletal Ewing's sarcoma].

5 patients diagnosed as having extraskeletal Ewing's sarcoma have been referred to our adult oncology unit since 1980. All were men, ranging in age from 18-57 (mean 32 years). The primary tumor was located on the trunk in 4 and in an extremity in 1. Wide tumor excision was feasible in only 2. 3 died within 27 months and 2 are alive, 13 and 67 months, respectively, following diagnosis. This study demonstrates the highly aggressive nature of extraskeletal Ewing's sarcoma and the need for early diagnosis and efficient chemotherapy.

Chronic hematocele complicating renal failure and hemodialysis.

A patient with a recent history of genitourinary tuberculosis, chronic renal failure and hemodialysis presented with a slow growing scrotal swelling that had enlarged during the last 3 years. Physical examination and sonography were suspicious for testicular tumor, and surgical exploration and inguinal orchiectomy were performed. Ultimately the mass proved to be a chronic hematocele, a rare complication of uremic coagulopathy and hemodialysis. Because hematocele may clinically and sonographically resemble a testicular tumor, the proper management of a complex multiseptated scrotal mass without obvious history suggestive of hematocele is surgical exploration and orchiectomy. Awareness of this common presentation may obviate orchiectomy.

[Tonsillar lymphoma].

3 patients with tonsillar lymphoma are described (a man of 68 and women of 62 and 57 years, respectively). The first had intermediate grade lymphoma localized in the tonsil and was treated by tonsillectomy and combined systemic chemotherapy. The second had low-grade lymphoma of the tonsil and widespread involvement of lymphoid tissue in the liver, spleen, mediastinum and retroperitoneum for which chemotherapy was given. The last had intermediate grade lymphoma, but had been misdiagnosed 4 years before as an undifferentiated carcinoma of the tonsil and was irradiated. After the malignant process had extended to the stomach, the correct diagnosis of diffuse large-cell lymphoma was made. Subtotal gastrectomy was followed by combined systemic chemotherapy. All patients responded well to treatment.

Another complication of thoracostomy--perforation of the right atrium.

Tube thoracostomy is an invasive procedure that is frequently life-saving but carries a risk of complications. We describe herein a complication not documented before-laceration of the right atrium. This occurred in a severely kyphoscoliotic patient with a markedly narrowed chest and led to his demise. This case attests to the extreme caution warranted when using trocar-type thoracostomy in patients with thoracic deformities.
