RESUMEN
A patient with HIV infection presented with multiple cutaneous Kaposi's sarcomata. Biopsy of one of these showed the presence of amastigotes within an otherwise typical Kaposi's sarcoma. Further investigations proved the patient to have visceral leishmaniasis (kala azar). Visceral leishmaniasis has been reported in HIV infection but it is rare and this presentation is unique. The patient made a good response to a prolonged course of treatment with sodium stibogluconate and allopurinol.

The histological slides of 273 breast cancer patients, treated by local excision and radiotherapy and followed up for 2-6 years, were reviewed in search of factors predictive of local recurrence. Local recurrence was found to be most closely related to the combination of a high proportion of intraduct carcinoma and extensive necrosis (comedocarcinoma). This latter group of 18 patients had a local recurrence rate of 50%. These patients are of particular interest since they form a small group with readily identifiable histological features.

A case is reported of a 48-year-old man with malignant sarcomatous pleural mesothelioma, who presented with a secondary deposit in the mandibular alveolus. We believe that this is the first reported case of this nature.

Sections from 447 children's spleens were examined for arteriolar hyalin. Hyalin is not found in the first year of life, but by the fifth year of life 60 per cent of cases show it. The positive cases include a wide variety of pathological conditions. The development of arteriolar hyalin in the spleen is age dependent, occurs early in life, and is not a pointer to any particular pathological condition.

In a 3 year period from the beginning of January 1985 to the end of December 1987, 474 biopsies obtained from 266 patients with serological evidence of human immunodeficiency virus infection were examined. Most frequent were skin biopsies of which 52% showed Kaposi's sarcoma, and transbronchial lung biopsies of which 40% showed Pneumocystis carinii pneumonia. Other opportunistic infections were much less common; Mycobacterium avium intracellulare was found in six biopsies and Cytomegalovirus in three. Non-Hodgkin's lymphoma was diagnosed in six patients.
