Retiform hemangioendothelioma (RH) is a rare, recently described, unique kind of low grade angiosarcoma. The tumor is characterized by distinctive arborizing blood vessels that mimic the appearance of rete testis. The tumor chiefly originates from the skin and subcutaneous tissue and has a tendency to recur locally. Only one case with lymph node metastasis has been reported previously. Another such rare case of RH is being reported in an adult female who presented with a subcutaneous nodule, underwent multiple recurrences and uniquely metastasized to regional lymph node.

The aim of this study was to diagnose acute leukemia in the population of Tripura using 3-lasers 7-color Flowcytometer. Immunophenotyping was done on peripheral blood samples of acute leukemia cases, by using 2-tube basic AML antibody panel. Samples collected from Regional Cancer Centre, Agartala included in this study 15 Acute Leukemia cases, reported during 2013 & 2014. Among them, 4 were ALL and 11 were AML cases. Out of 15 cases, 12 were adults (9 men and 3 women ranging from 17 to 77 years of age) and 3 were from pediatric patients. A strong correlation (r=0.92) is obtained between the blast cell count by microscopy &flowcytometry. Moreover, this Immunophenotyping procedure on peripheral blood samples also allowed an efficient discrimination between the various cell lineages and facilitated the accurate leukemic blast cell percentage.
