Abstract
The frequency of a supraglottic carcinoma as an occult primary of cervical lymph node metastasis is high therefore such cervical lymph node involvement is an early symptom.
Our study will reference a difficult case of supraglottic carcinoma that ocular inspection assisted in differentiation on the tongue side of the epiglottis base which is a rare site of origin. With this case,a 59-year-old man,the chief complaint was a mass on the lower left-side of his chin. He noticed a sudden increase in size of this mass and consulted with another hospital's otolaryngology department. Aspiration biopsy cytology was performed on the mass and a squamous cell carcinoma (SCC) was diagnosed.
He was introduced to this hospital with occult primary cervical metastatic cancer of the lymph node without having had the primary tumor identified yet by medical examination. PET-CT imaging revealed abnormal accumulation in the cervical lymph node to the left of the vallecula. We performed ａ biopsy from the lesion which seemed to be an epiglottic cyst. Because SCC was diagnosed,we took the epiglottic cyst to be the primary tumor of the cervical lymph node metastasis. We performed a horizontal partial laryngectomy and left neck dissection,followed postoperatively by radiation 60Gy treatment. There Has been to recurrence of the primary tumor nor metastasis as of two year and four months since surgical treatment.
