Metastasis of a tumor to the tonsil is a rare event and moreover, prognosis is typically poor. Here, we will report a case with good prognosis where a palatine tonsillar tumor which had metastasized from a small cell carcinoma of the lung was surgically excised followed by the neck dissection.
A 70-year-old male had been in our hospital for treatment of lung carcinoma. Following a history of pharyngalgia for one month, he was sent to our division for examination. A tumor mass which was partially ulcerated, was revealed in the superior region of the left palatine tonsil. Tumefied submandibular lymph nodes were palpable. A histopathological examination of biopsy material taken from the left palatine tonsil resulted in the diagnosis of a small cell carcinoma. Since the primary tumor seemed to have been removed successfully and metastasis was not observed except in the palatine tonsil, the patient was treated by radical excision of the tumor, followed by the neck dissection. After surgery the patient underwent two courses of a combination chemotherapy with CDDP + VP 16 + MMC, and subsequently left the hospital.
Twenty two months after surgery the patient remains stable without a relapse.
