A case of Lennert's lymphoma.

A 73-year-old man who presented with a tonsillar mass and generalised lymphadenopathy died two months after admission to hospital. The appearances in the surgical biopsy material resembled those of Lennert's lymphoma, while the necropsy findings were those of a diffuse lymphocytic lymphoma composed mainly of cells with small nuclei showing only slight irregularity. The implication of these findings in relation to the nature of Lennert's lymphoma are briefly discussed.

Spermatogenesis in an infertile XYY man.

Testicular histology and meiosis has been studied in an XYY male patient identified at an infertility clinic. This man was found to have an XYY set chromosome complement in 15% of spermatogonial metaphases. There was no evidence of 2 Y chromosomes at diakinesis but there appeared to be a slight excess of sperm with a fluorescent Y body.
