Abstract

We report a case of myxoinflammatory fibroblastic sarcoma in a thirteen year old gilrl who presented with a tender swelling in the left upper back. The tumor consisted of varying proportions of inflammatory, myxoid and hyalinized areas. Large bizarre cells with virocyte like inclusions and lipoblast like cells were present. To the best of our knowledge this is the first reported case of myxoinflammatory fibroblastic sarcoma of the back, the extremities being the commonest site of involvement. Due to its varied histologic appearance, the tumor should be differentiated from various benign and malignant soft tissue lesions.
