During the past five years, 339 new head and neck carcinoma cases were treated at our clinic. Among them, cases with cervical lymph node metastasis were examined, and the following results were obtained: 1. The cases with the pharyngeal carcinoma most frequently had the metastatic lymph node at their first hospital visit. Among those cases, the nasopharyngeal carcinoma (NPC) revealed the highest incidence of the metastasis. 2. The ratio of metastasis was observed according to the exact location of each organ. a) NPC revealed no difference among the sites (superioposterio, lateral and inferior wall). b) In the hypopharyngeal carcinoma, the piriform sinus type showed a higher frequency than the other sites (postcricoid and posterior wall type). c) The supraglottic type of laryngeal carcinoma had a higher incidence than the glottic and subglottic type. 3. The side of the metastatic neck lymph node had an intimate relationship to the primary lesion. Therefore, with knowledge of this fact, the primary site can be conjectured. 4. In cases where NPC is suspected with the neck metastasis, the immunological examination of the anti EBV titer is recommended while a biopsy from the lymph node is prohibited. 5. Three cases were observed with neck metastasis, the origins of which unknown. For such cases, various kinds of therapeutic procedure should be performed.
