A Case of Duplicated Malignant Lymphoma and Maxillary Cancer

Abstract

A rare case of duplicated primary neoplasm (malignant lymphoma in head and neck region, and left maxillary cancer) was reported.A 55-year-old man complained of multiple tumors in the neck on both sides and of a left nasal obstruction. Cervical tumors were diagnosed as malignant lymphoma histiocytic type by excisional biopsy. The homogeneous cloudy shadow in the left maxillary sinus with partial bone defect of the lateral wall was roentgenologically observed and pathological findings of the nasal tumor were also suspected as malignant lymphoma. Therefore, the shadow of the left maxillary sinus was supposed to be malignant lymphoma. After chemotherapy and radiotherapy for malignant lymphoma, cervical tumors disappeared, but the left nasal obstruction and headache remained and became more apparent. Four months after treatment for malignant lymphoma, the probe operation clarified the squamous cell carcinoma in the left maxillary sinus.
