Background: Soft tissues tumours are tumours of mesenchymal origin excluding epithelial, skeletal tissue, reticuloendothelial system, brain coverings and solid viscera of the body. The objective of this study was to know the histopathological pattern of soft tissues tumours in the Pathology Department of Lady Reading Hospital Peshawar Khyber Pakhtunkhwa Pakistan.
Methods: This descriptive study was conducted on retrospective data from January 2009 to December 2013. All the soft tissues biopsy specimens were received in 10% formalin, labelled, gross performed, sections processed in alcohol, xylene, wax, block prepared, frozen, microtome sections taken and processed for H&E staining, mounted and reported by a Histopathologist. The inclusion criteria were any sufficient soft tissue tumour biopsy specimen of any age, sex, location in body whereas the exclusion criteria were autolysed biopsy specimen. A minimum of four and maximum of eight sections and 5 micron thick were taken from each specimen.
Results: A total of 267 soft tissues tumours biopsy specimens were received in the pathology laboratory with age range of 1-75 years, with mean age of 30.68±17.71 years. Male to female ratio was 1.13:1. Amongst the total, benign tumours were 176 (65.91%). Haemangioma, 73 (27.3%) was the commonest tumours followed by lipomas 41 (15.4%) cases. Amongst the total malignant tumours, i.e., 91 (34.08%), rhabdomyosarcoma, 35 (13.1%) was the commonest tumour followed by angiosarcoma 14 (5.2%) cases.
Conclusions: Haemangioma is the commonest benign tumour and rhabdomyosarcoma is the commonest malignant tumour in this study.
