We describe three cases of blood boils of the maxillary sinus that were suspected to be malignant tumors. The patients were a 27-year-old female, a 52-year-old male and a 24-year-old male. The chief complaints in all cases were unilateral nasal obstruction and nasal bleeding. CT examination showed that the tumors occupied the entire unilateral maxillary sinus, and expanded with maxillary bone thinning. Biopsies performed through the nasal cavity revealed the tumorous masses to be benign. Ultimately, the tumorous masses were surgically extirpated without any transfusion, and the histopathological diagnosis turned out not to be the more typical hemangioma, but rather so called blood boil.
