Partial monosomy 13q and partial trisomy 18p: case report with necropsy findings

We describe a stillborn female infant with severe intrauterine growth retardation and multiple congenital anomalies. She was found to have a deletion of 13q22----qter and trisomy of 18p11.2----pter, resulting from a maternal balanced translocation.

18q+, the progeny of a balanced translocation t(1;18)mat: case report with necropsy findings

A female infant with additional genetic material on the long arm of chromosome 18 is described. Cytogenetic studies of the infant and her mother showed that the altered region resulted from an unbalanced translocation of part of the long arm of chromosome 1. This chromosomal abnormality has not been reported previously, according to a recent registry of abnormal chromosome patterns. The patient had hydrops fetalis and multiple congenital abnormalities, involving the cardiovascular, respiratory, and skeletal systems, together with unusual facies. External features, radiological findings, and gross and microscopical examination at necropsy are presented and compared with previously reported cases of related but dissimilar chromosomal abnormalities.

Lymphangioma presenting as a nasal polyp in an infant

We describe a pedunculated lymphangioma presenting as an isolated nasal polyp in an 11-month-old male infant with light and electron microscopic findings. This lesion occurring in an infant must be distinguished from more common benign and malignant intranasal masses.

Chondrosarcoma of the nasal septum: a case report

Chondrosarcoma arising in the nasal septum has been previously described only 11 times. In this report, another case occurring in an 89-year-old man is discussed. The rarity of such a tumor arising in previously normal cartilage is emphasized. Prognostic factors and surgical treatment are discussed.

Deletion of the short arm of chromosome 3: a case report with necropsy findings

A male infant with partial deletion of the short arm of chromosome 3 is described. The features this patient shares with six previously reported cases include microcephaly, dolichocephaly, micrognathia, epicanthic folds, ptosis, low set or malformed ears, postaxial polydactyly, and growth or mental retardation or both. In addition, visceral anomalies not previously reported in association with this chromosomal abnormality are described. These characteristics may constitute a recognisable clinical syndrome.
