filtrated by numerous atypical lymphocytes, plasma cells, histio- blasts ant cells are arranged preferentially in clusters beneath the squamous surface and crypt epithelium, and are only occasionally seen in intrafollicular areas. They have a foamy cytoplasm and the nuclei are arranged at the periphery of the cells. The giant cells react with antibodies to S-100 and CD68. Other features of chronic HIV infection are monocytoid B-cell hyperplasia, paracortical and interfollicular expansion with immunoblasts and plasma cells, often with Russell bodies, and prominent interfol-licular clusters of high endothelial venules. The histolog-

ical features in patients with advanced disease are effacement of nodal architecture, loss of the normal lymphoid cell population with replacement by benign plasma cells and increased vascularity [53, 174, 197].

Acute non-bacterial tonsillitis and hypertrophy can be the first sign of a post-transplant lymphoprolifera-tive disorder [163]. In a study of 42 paediatric transplant patients, 28% had involvement of Waldeyer's ring [147]. In immunosuppressed children in particular with rapid progressive enlargement of the tonsils lymphoma should be suspected [180].
