Splenic tumours--autopsy study of ten years.

Human spleen, though being the largest component of reticuloendothelial system, is a very rare site of tumor metastases. Splenic metastases are usually seen as part of multi-organ involvement. Autopsy study conducted over a period of 10 years revealed that the incidence of neoplastic involvement of spleen was 1.

Unusual mesenchymal tumour of uterus--a case report with immunohistochemical findings.

This is a case report of a mesenchymal tumor of uterus in a 60 year female initially interpreted as myxoid leiomyosarcoma. Immunohistochemical studies were negative for smooth muscle actin, desmin and p53 but positive for S-100 protein. The tumor was therefore reclassified as a low grade malignant mesenchymal tumor of neural origin.

Fine-needle aspiration cytology in lymphadenopathy of HIV-positive patients.

Fine-needle aspiration cytology (FNAC) of 32 HIV-positive cases presenting with lymphadenopathy was performed to evaluate its role in this group of patients. For each case air-dried smears were stained with Leishman, hematoxylin and eosin, and Zeihl-Neelsen stains for acid fast bacilli (AFB). The results were tuberculous (TB) lymphadenopathy (15), reactive lymphadenopathy (10), acute lymphadenitis/abscess (5), and suspected malignancy (2).
