Organized hematoma is a rare progressive cystic lesion. In this paper, we report a case of organized hematoma developing in the oral floor of a 41-year-old woman. Intraoral examination revealed an elastic hard and mobile mass measuring 40 × 30 × 20 mm in the right side of the oral floor. Computed tomography showed a well-defined mass lesion. A high-density area was partially seen around the rim. On T1-weighted, coronal section MR images, the mass lesion appeared as a slightly high-signal area with a partially iso-signal area. On the T2-weighted images, the mass was seen as a low-signal area. The mass was entirely removed with the patient under general anesthesia. Histopathological examination of the specimen showed an old blood clot encapsulated by dense fibrous connective tissue without an epithelial lining. Granulation tissue with infiltration of macrophages and pathologic calcification was seen between the blood clot and fibrous capsule. On the basis of the above-mentioned findings, the mass lesion was finally diagnosed as an organized hematoma. No recurrence has occurred as of 5 years 6 months after surgical removal.
