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.

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.
