We have evaluated a sister and brother with a similar pattern of malformations and death in early childhood associated with partial duplication chromosome 5p and possibly deletion of 9p. The father and the brother and several paternal relatives are carriers of the balanced translocation t(5;9) (p13;p22). The malformations which the two have in common are: prominent forehead, flat nasal bridge, long thin fingers, bilateral equinovarus deformity of the feet, diaphragmatic hernia and kidney malformations. The children died at ages 4 months and 27 months, the latter showing marked psychomotor retardation. The chromosome abnormalities, clinical history, and phenotypic features of our patients are similar to the case reported by Monteleone et al (1976). The findings in our patients and Monteleone et al. (1976) are not similar to those in other reported cases of partial and complete 5q duplications, perhaps because the others do not have partial deletion of 9p.

Desmoplastic small round cell tumor is a rare, aggressive neoplasm that mainly affects young male patients and is characterized by a reciprocal translocation t(11;22)(p13;q12) associated with the EWS-WT1 gene fusion transcript. Clinical, histopathologic, immunohistochemical, and molecular genetics features were reviewed for 32 tumors. There were 29 male and three female patients, with ages from 6 to 54 years (mean, 25 years). The main clinical signs and symptoms included abdominal pain (eight patients), weight loss (five patients), and presence of umbilical hernia (four patients). Two tumors primarily involved the ethmoid sinus and the soft tissues of the scalp; the other tumors (mean size, 10 cm) involved the abdominal cavity (88%). One patient presented initially with an axillary lymph node metastasis. Generally, all tumors showed the typical histologic findings of variably sized clusters of small, round, or spindled cells lying in a desmoplastic stroma. The neoplastic cells in formalin-fixed, paraffin-embedded tissue sections were positive for desmin (dot pattern) (81% of the cases), WT1 (91%), keratin (87%), neuron-specific enolase (84%), CD99 (23%), and actin (3%). The EWS-WT1 gene fusion transcript was detected in 29 of 30 tumors. One tumor with typical clinicopathologic and immunohistochemical features did not show the gene fusion. Follow-up for 27 patients showed that 19 patients (70%) died of uncontrolled, local, or widespread metastatic disease 3-46 months (mean, 20 months) after diagnosis, and eight patients were alive with known evidence of disease. Occasionally, desmoplastic small round cell tumor lacks the classic clinical, histologic, and immunohistochemical features. This study emphasizes the utility of analysis of the EWS-WT1 gene fusion transcript, which was performed on paraffin-embedded tissues, to confirm the diagnosis.
