Soft tissue tumours and tumour like lesions - a demographic and clinicopathologic study of 461 cases from different regions of Bangladesh.

: Soft tissue tumours and tumour like lesions are relatively rare. They pose diagnostic difficulty due to wide morphological variation as well as overlapping clinical and pathological features. The relative frequency of soft tissue tumours varies throughout world. This study was undertaken to find out the distribution of soft tissue tumours and tumour like lesions in Babgladesh. Four hundred and sixty one cases of soft tissue tumour and tumour like lesions were studied to see the demographic and clinicopathologic pattern. Benign 320(69.4%) and malignant 141(30.6%) cases were recorded. Of all cases mean age was 31.07±16.87 years with M:F ratio of 1:0.71 (p=0.001). Upper extremity was the most common site. Majority of the benign cases (84.1%) were superficially located whereas majority of malignant cases (89.2%) were deep seated (p=0.001). Lipoma and fibrosarcoma was the most common benign and malignant tumour respectively observed in this study. In childhood group, rhabdomyosarcona was the commonest one. The distribution pattern of soft tissue tumours in Bangladeshi population is roughly similar to that described in other countries with few exceptions.
