A case was reported of squamous cell carcinoma arising in left upper neck of 61-for 1 year old male.
The patient complained that had been suffered painful swelling in left upper neck region for 1 month since he had his left upper teeth extracted.
An elastic hard tumor the size of a baby's fist with adhesion underneath was found in the first visit examination.An en-block resection of tumor with adhesive surroundings was performed, though preoperative biopsy showed no evidence of malignancy.
Histopathological examination of the specimen revealed that the tumor was squamous cell carcinoma. Even though we had not found tumor cell remained on surgical margin area, 60Co (5, 000 rad) irradiation and Peplomycin (50mg) chemotherapy was performed after the resection. The patient was followed up for 2 years administering Picibanil (5KE/week) and had no local reccurance or metastasis.
We concluded that this case was Branchiogenic carcinoma because of the below characteristics;
1.Tumor was located between M. sternocleidmastoideus and V.juglaris internal of upper neck region.
2.Tumor had cystic cavity with keratinized substance inside.
3.Histopathological examination revealed that the cystic structure was not formed by necrosis caused by carcinoma.
4.Numbers of lymphoid tissues with germinal center were found in the specimen.
5.Even though we tried Otorhinolaryngologic, internal examinations and further research of maxillofacial region, we could not find any primary lesion so that the tumor of the upper neck was deened not metastatic.
