Histopathological Spectrum of Soft Tissue Tumours in Paediatric Agegroup in a Tertiary Care Hospital

Background: 'Soft tissue' is a non-epithelial extra skeletal tissue of the body exclusive of the reticuloendothelialsystem, glia and supporting tissue of the various parenchymal organs.¹ It is represented by the voluntarymuscles, adipose tissue and fibrous tissue along with the vessels serving these tissues. The objective of thisstudy was to study the histopathological features of soft tissue tumors and to study the occurrence of soft tissuetumors in relation to age, sex and anatomical site.Methods: The study comprise of 50 cases studied over period of two years. All soft tissue tumours, their grossfeatures, microscopic findings were analysed in detail. Soft tissue tumors were divided into Benign andMalignant categories and further sub typing were done according to World Health Organization (WHO)classification. The distribution of soft tissue tumors according to age, sex and site of occurrence was studied.Results: Out of 50 cases of soft tissue tumors 45 cases were benign 5 cases were malignant. The most commontumour was vascular tumour (24cases) followed by adipose tissue tumour (14cases) and skeletal muscle tumour(5cases). The benign tumours (90%) were more common than malignant tumour (10%).The malignant softtissue tumors was seen more common in male than female.Conclusion: The benign tumours were more common than malignant tumour. The most common benign tumourwas Haemangioma followed by lymphangioma. Rhabdomyosarcoma (RMS) was common malignant tumour.Benign tumors were seen in male as compare to female. The most commonly involved site for the benign softtissue tumour was head & neck. Again the most commonly involve site for the malignant soft tissue tumour waslower extremities.
