Abstract |
A 1-year-old female child with multiple dysmorphic features including microcephaly, hypertelorism, a short philtrum, low set ears, a narrow high arched palate, micrognathia and growth retardation was found to have a de novo chromosome abnormality including a partial duplication of the short arm of chromosome 2 and a partial deletion of the long arm of chromosome 17. The clinical features of the case shared many similarities to previous reports of trisomy 2p. Three years later, ecchymotic spots appeared around the left ocular region. Further clinical and pathological examination confirmed the diagnosis of a neuroblastoma. This is the first case of an unbalanced translocation, 46, XX, der (17), t (2; 17) ( p23; q25), showing the development of a neuroblastoma in addition to the dysmorphic features. We suggest that trisomy 2p including the N-myc proto-oncogene may have predisposed the patient to the development of a neuroblastoma.
