The increasing incidence of multiple primary carcinomas occuring in the upper aerodigestive tract is well documented, with the accepted incidence being as high as 20-30%. The fiberoptic endoscopy has also enabled visualization of areas previously inaccessible without general anesthesia. A prospective panendoscopic examination of the upper aerodigestive tract was peformed on 104 patients with squamous cell carcinoma of head & neck in our hospital between 1989 and 1994. Five second primary cancers (4.8% ：2 stomach, 2 esophagus, 1 lung cancers) were detected endoscopically. These finding should reinforce the belief that head & neck cancer is a panmucosal disease of the aerodigestive tract that silent second primary cancers are not uncommon. So every effort should be done to detect second primary cancers in head & neck squamous cell carcinomas. Panendoscopy has proved valuable in achieving that.

It is the purpose of this paper to determine the relative frequency of the neoplastic vs. non-neoplastic disease in a series of surgically removed parotid and submandibular masses. The study was conducted a retrospective review of 249 consecutive, operated patients' records seen over a 9-year period from 1985 through 1993 at Department of Otolaryngology-Head and Neck Surgery, Korea Cancer Center Hospital. One hundred and fifteen patients had parotid mass and 134 patients had submandibular mass. All the specimen surgically removed were studied histopathologically. The numbers and percentages of patients are reported along with a pathological classification of the lesions encountered: neoplastic(benign, malignant) and non-neoplastic (inflammatory, non-inflammatory). There were 59 benign, 46 malignant, 6 inflammatory, 4 non-inflammatory in 115 parotid mass, and 33 benign, 48 malgnant, 47 inflammatory, 6 non-inflammatory in 134 submandibular mass. One-hundred-eighty-six of entire 249 patients had tumor involvement, for a 74.7% incidence of neoplasia. There was a neoplastic predominance in parotid mass(91.3%) and a relative inflammatory predominance in submandibular mass(35.1%).
