Abstract
Two patients with squamous cell carcinoma of the head-and-neck with concurrent non-Hodgkin lymphoma were reported. One patient was a 77-year-old man, he had well differentiated squamous cell carcinoma of the oropharynx with neck metstasis, and non-Hodgkin's lymphoma (REAL classification: Peripheral T-cell lymphomas, unspecified) of the neck lymph nodes simultaneously. The other patient was a 61-year-old man, he had well diffrentiated squamous cell carcinoma of the vocal cords, and non-Hodgkin's lymphoma (REAL classification: Mantle cell lymphoma) of the palatine tonsil simultaneously. Double primary malignant tumors composed of squamous cell carcinoma of the head-and-neck and malignant lymphoma are relatively rare, especially those detected simultaneously are very rare.
