Extraskeletal primary Ewing's sarcoma of the nasal cavity

1644 consisted of hemimandibulectomy with primary reconstruction using autologous costochondral rib graft. Although controversial, we advocate this method of reconstruction in infants with extensive mandibular continuity defects. In the present case the histological features varied on the initial biopsy and resection specimens, differing in exposure to chemotherapy which had apparently eradicated the small round cell population.

Extraskeletal primary Ewing’s sarcoma of the nasal cavity Ays ¸e Iriz a,*, Levent Albayrak b, Adil Eryilmaz a a Ankara Numune Hospital, Department of Otorhinolaryngology, Third Otorhinolaryngology Clinic, Ankara, Turkey b Ankara Numune Hospital, Department of Pathology, Turkey Ewing’s sarcoma (ES) and primitive neuroectodermal tumor represent the most frequent small and round cell bone tumors of childhood and adolescence. ES is the second most common primary malignant tumor of bone in children. In this article, a 1-year-old male patient with ES is presented and recent update on this entity is discussed. Computed tomography (CT) scans of the sinuses revealed a mass that appeared to be originating from the right inferior turbinate and filling the anterior part of the nasal cavity. The patient underwent complete removal of the mass with endoscopic nasal surgery under general anesthesia and was treated with adjuvant chemotherapy. Clinically and radiologically no recurrence of disease was noted during a follow-up period of 1 year. Although ES is extremely rare among nasal cavity neoplasms, it should be considered in the differential diagnosis.

Esophageal atresia with tracheoesophageal fistula is an uncommon congenital anomaly. Duplication of the gastrointestinal system is even more infrequent. We describe an unusual case of these two conditions occurring in the same children, although distal esophageal duplication was not recognized initially after repair of the esophageal atresia and tracheoesophageal fistula.
