Abstract
A case of cystic lymphangioma in the right submandibular region of a 12-year-old male, treated with local injection of OK-432 is presented. The tumor was clinically diagnosed as hemangioma at the first visit. Compression therapy was subsequently performed; the lesion showed marked shrinkage. The final diagnosis of cystic lymphangioma was based on biochemical analysis of contents aspirated from the lesion which relapsed 10 months after compression therapy. Therefore, local injection of OK-432 was performed two times (first; 0.05KE, second; 0.025KE, total; 0.075KE) . The tumor remarkably reduced in size without serious complication. There has been no evidence of recurrence for 2 years since treatment.
