[Myxoma and myxoid chondrosarcoma of the nasal septum: two case reports].
Myxoid neoplasms are histopathologically divided into true myxomas and other tumors of myxomatous character. In the region of the nasal septum, this tumor entity is extremely rare. In the following two case reports, the unusual findings of a myxoma and a myxoid chondrosarcoma of the nasal septum are presented and discussed. At first visit, both patients reported a slowly progressing, bilateral nasal obstruction. In nasal endoscopy, both showed a smoothly surfaced, spheroid, soft tissue mass in the dorsal nasal septum. On CT-scans, a displacing growth was described for the first patient; in the second patient, a bony arrosion of the floor of the sphenoid sinus was suspected. Both lesions were surgically completely removed. The histopathological diagnosis was myxoma in the first and myxoid chondrosarcoma in the second patient. An early, locally recurrent tumor in the second patient could also be surgically removed. Both patients have been in full remission for more than a year. In spite of the similar symptoms and clinical findings, histopathologically different myxoid neoplasms of the nasal septum show marked variations in growth and recurrence.
