The authors present the case of a 20-year-old woman who developed a peripheral neuroectodermal neoplasm of the thoracopulmonary region (Askin tumor) 7 years after achieving complete remission of stage-IV Hodgkin's disease. The previous treatment had consisted of eight courses of alternating MOPP/ABVD combined with involved-field 20-Gy radiotherapy. The second neoplasm appeared in a nonirradiated area of the chest wall, with erosion of the ribs as shown by sonography and computed tomography. The histological pattern was in accordance with a generic diagnosis of a malignant small cell tumor; the immunostaining positivity of the neoplastic cells for the neuron-specific enolase allowed us to make the diagnosis of a tumor with a neuroectodermal origin. Partial resection of the neoplasm and four courses of chemotherapy including adriamycin, cisplatin, and ifosfamide induced a complete remission, confirmed by surgical restaging. She is alive and well 10 months after the completion of therapy. The clinical, radiological, and microscopic features of this tumor occurring as a secondary neoplasm after Hodgkin's disease are described.

A retrospective review of 16 patients operated upon for primary mediastinal tumours was carried out. Anterior mediastinal tumours seen included retrosternal goitre (2), benign cystic teratoma (1), benign thymoma (1), malignant thymoma, spindle cell type (1) and Hodgkin's lymphoma, nodular sclerosing type (1). Mid-mediastinal tumours included bronchial cyst (1), mediastinal granuloma (1), and pulmonary arterio-venous fistula (1). Neurilemmoma (2), neuroblastoma (1), ganglioneuroma (1), Askin tumour (1), neurofibroma (1) and benign histiocytoma (1) constituted the tumours of the posterior mediastinum. The tumours were successfully resected with minimal operative morbidity and no mortality.

Mutant frequencies (Mfs) at the two genetic loci, the hypoxanthine phosphoribosyl transferase (hprt) gene and the T-cell receptor (TCR) gene were evaluated in pediatric cancer patients before starting chemotherapy or radiotherapy. The study population consisted of 27 patients with various solid tumors (mean age +/- SD; 5.5 +/- 5.1 years, range; 0.2-14.5 years), 5 patients with acute leukemia (10.3 +/- 6.1, 1.3-17.0 years), and 26 healthy controls (11.6 +/- 4.0, 4.4-22.2 years). Although the age distributions were different, the mean Mf values of the hprt and the TCR loci were comparable among these three groups. On an individual basis taking the age factor into consideration, the hprt-Mfs of 3 patients with solid tumors, i.e., two patients with Hodgkin's disease and one patient with Askin tumor, were found to be well above the 95% confidence limit. There were no patients with a TCR-Mf exceeding the 95% confidence limit. These data suggest the possibility that some patients with solid tumors may be predisposed to mutational susceptibility before treatment. The assay of the hprt-Mf appears more sensitive than the TCR-Mf assay in distinguishing these patients.

The incidence of malignancy after renal transplant has been reported to range from 4% to 18%. Tumors of the skin and lip tend to be the most common with non-Hodgkin lymphoma comprising 20% of all neoplasms. Primitive neuroectodermal tumors (PNET) are collectively described as being a part of the Ewing sarcoma family of tumors. PNET occur more commonly in the second decade of life, predominantly affecting Whites and Hispanics, and rarely occur in individuals of African or Asian descent. The most common primary site of involvement is along the central axis, particularly the chest (Askin tumor), but it can arise in any soft tissue. PNET also occur in the head and neck. PNET involving the cervix, urinary bladder, uterus, and vagina have been reported. We describe a case of a 15-year-old female who, 9 years after receiving a living related renal transplant, developed a post-transplant PNET of the uterus.
