Cancer screening by local volunteers.

In a tribal village in Kerala, India, local volunteers were trained to work in a programme for the primary prevention of tobacco-related cancers and the secondary prevention of common cancers. They gathered data on the use of tobacco and alcohol in a population of some 19,000 people, and identified one or more warning signals of cancer in 430 persons, who were subsequently examined by physicians. Confirmation was obtained of 10 new cancers, 7 recurrent cancers, 46 oral precancerous conditions, and 58 precancers at other sites. The community's awareness of cancer problems increased and the people learnt about the importance of self-examination in the detection of breast cancer and oral cancer.

Malignant systemic mastocytosis.

Malignant Systemic Mastocytosis is a very rare condition. Only about less than 40 well documented cases have been reported as per the available literature. The paper presents the case report of a 54 year old male patient who presented with huge hepatosplenomegaly and abdominal lymphadenopathy. Splenectomy specimen was 17 x 16 x 10 cm size with cut surface studded with numerous tiny 1-2 mm nodules. Histologic sections of spleen showed extensive mast cell (typical and atypical) infiltrates. Liver biopsy and abdominal lymphnode biopsy specimens and bone marrow smears also showed similar infiltration by mast cells. Special stains done for non-specific esterase and chloracetate esterase showed strong positivity for mast cells. The results of immunohistochemical and electron microscopic studies are also presented.
