Primary NK/T-cell lymphoma of the larynx.

Laryngeal extranodal non-Hodgkin lymphoma is uncommon, accounting for less than 1% of all laryngeal neoplasms; the B-cell phenotype is predominant. Lymphomas outside the nasal cavity are rare and highly aggressive. We present a case of primary natural killer T-cell (NK/T-cell) lymphoma of the larynx that arose in a 45-year-old man. Because only a limited amount of data is available on laryngeal NK/T-cell lymphoma, the mainstay of treatment remains unclear, although some data suggest that radiotherapy alone is the best option. Our patient was treated with chemotherapy and radiotherapy, and he remained in remission 2 years later.

Angiomyomatous hamartoma in a submandibular lymph node: a case report.

Angiomyomatous hamartomas have been found almost exclusively in the inguinal and femoral lymph nodes; few reports of these lesions in the head and neck region have been published. We present a case of angiomyomatous hamartoma in the submandibular area, a site that has not been previously reported in the literature. The mass was initially diagnosed as an enlarged lymph node. When it did not regress following broad-spectrum antibiotic treatment, the patient, a 51-year-old woman, underwent an excisional biopsy. Histopathology identified the mass as an angiomyomatous hamartoma. At follow-up 3 years and 9 months postoperatively, the patient exhibited no evidence of recurrence on physical examination and computed tomography. Even though angiomyomatous hamartoma of the head and neck is rare, we suggest that otolaryngologists include it in the differential diagnosis of head and neck masses.
