Physical examination reveals a mass at least 3 cm in diameter, deep to the anterior border of the sternomastoid muscle with no additional evidence of adenopathy. Inspection of the oral cavity and oropharynx and flexible nasopharyngoscopy reveal no obvious abnormality. Differential Diagnosis A lateral neck mass presenting in an older patient, particularly one who smokes, should be considered metastatic carcinoma in a cervical lymph node until proven otherwise. The most likely diagnosis is metastatic squamous cell carcinoma (SCC), either from a mucosal or cutaneous site.

There is a firm, nontender mass overlying the right angle of the mandible, somewhat mobile but with a suggestion of fixity to the overlying skin. No adenopathy is palpable elsewhere in the neck. No mucosal lesions or cutaneous tumors are present. ■ Clinical Photograph A right parotid mass is clearly visible.

There is inferior extension of the tumor into the oropharynx along the left lateral wall. The anterior nasal space is not involved. There is no involvement of the skull base. Enlargement of the left deep cervical chain is noted (5 ϫ 4 cm maximum diameter). Retropharyngeal and supraclavicular nodes are not enlarged. Black arrows indicate the location of the primary tumor.
