An adolescent case of sellar osteochondromyxoma in the setting of spondyloepiphyseal dysplasia.

PURPOSE

Osteochondromyxomas (OMX) are rare congenital bone tumors that have only been described in the context of Carney complex syndrome (CNC). Data on OMX as a separate entity and in association with other disorders remain limited, making both diagnosis and treatment difficult.

METHODS

A case report of a 17-year-old female diagnosed with sellar OMX is presented in the setting of spondyloepiphyseal dysplasia (SED). We discuss the radiographic and histopathological interpretations in addition to reviewing the current literature on OMX.

RESULTS

A successful gross total resection of the tumor was achieved via an endonasal endoscopic transsphenoidal approach. A diagnosis was established radiographically and pathologically.

CONCLUSION

The diagnosis and treatment of OMX are best achieved via tissue biopsy. Following confirmed osteochondromyxoma cases long term for recurrence and outcomes will be essential in understanding its natural tumor history and in establishing standard treatments.
