Abstract

Orbital mesenchymal chondrosarcoma is a very uncommon lesion of the bone and extraskeletal tissue. To our knowledge, approximately 30 cases have been described. We present the case of a 52-year-old male who presented with a history of progressive proptosis and chemosis of the right eye caused by an orbital tumor. He underwent exenteration of the right orbit, and the histological examination revealed a mesenchymal orbital chondrosarcoma. This paper attempts to describe a rare entity that should be considered in the differential diagnosis of calcified orbital lesions, especially in young adults. Complete removal of the tumor is the mainstay of treatment, but adjuvant radiation therapy and chemotherapy should be considered.

Highlights

  • Mesenchymal chondrosarcoma of the head and neck is an uncommon tumor with potential for exhibiting highly aggressive behavior

  • In the head and neck region, it presents with a predilection for the maxillofacial skeleton, where it has been reported to occur in particular in the mandible and maxilla [4]

Summary

Introduction

Mesenchymal chondrosarcoma of the head and neck is an uncommon tumor with potential for exhibiting highly aggressive behavior. This lesion is a malignant small round cell neoplasm with focal cartilaginous differentiation, often with a pericytomatous vascular pattern. In the head and neck region, it presents with a predilection for the maxillofacial skeleton, where it has been reported to occur in particular in the mandible and maxilla [4]. It is usually seen in younger age group compared to conventional chondrosarcomas [3]. The aim of this paper is to report a case of mesenchymal chondrosarcoma of the orbit
