Mesenchymal chondrosarcoma in the pectoral re-gion, case report

Case report

Abstract

Introduction: The extraskeletal mesenchymal chondrosarcoma (ESC) corresponds to 1% of all malignant soft tissue tumors. They are located mainly in the head and neck region, especially in the orbit, and in the dura mater of the skull, followed by the lower extremities, particularly at the level of the thigh. Pectoral location is rare, reason for report.

Case report: 38-year-old male patient who developed a nodule approximately 2 cm in diameter located in the right pectoral region with minimal pain on palpation and rapid growth. Two months later, at the time of resection, the nodule measures 7.5 x 6.5 x 3.5 cm, and weighs 106g. It has a lobulated appearance, greyish brown color, when cut it is of a rubbery consistency and a nodular whitish surface with central areas of mineralized / calcified appearance. 6 paraffin sections are processed and diagnosed as mesenchymal chondrosarcoma (CM).

Evolution: The patient was discharged and is being monitored by an outpatient clinic. He has not developed recurrences to date.

Conclusions: The accelerated growth of a mass of cartilaginous consistency was correlated in this patient with the presence of an extraskeletal mesenchymal chondrosarcoma.
