Florid cemento-osseous dysplasia (FCOD) can rarely be associated with bone lesions, including simple bone cysts (SBCs). Only a few cases showing the co-occurrence of these two distinct entities have been reported in the literature. This article reports two new cases of SBCs within FCOD. The first case involves a 37-year-old Black female with a large radiolucent lesion around the apex of the right third mandibular molar, accompanied by multiple cemento-osseous lesions around the mandibular teeth. Surgical exploration revealed an empty bone cavity, confirming the diagnosis of an SBC. Curettage of the bone walls was performed to stimulate healing, with promising results observed at the nine-month follow-up. The second case concerns a 44-year-old Black female presenting with a radiolucent lesion at the site of extraction of the left third mandibular molar and a slightly painful radiolucent/radio-opaque lesion in the apical region of the right first mandibular molar. Surgical exploration confirmed an SBC in the region of the left third mandibular molar and a bone biopsy was made. Histopathological analysis confirmed FCOD. Curettage of the bone wall was again used to promote healing through increased bleeding. At the 30-month follow-up, new dysplastic lesions had appeared, the initial SBC had healed completely, and a new SBC seemed to have developed in the apical region of the left second mandibular premolar. These cases highlight the importance of considering SBCs in the differential diagnosis of well-defined radiolucent lesions and demonstrate that surgical intervention for SBC-associated FCOD can yield favorable outcomes. From these cases, we learn the critical need for accurate diagnosis to avoid unnecessary treatments and the value of regular follow-up to monitor for recurrence or new lesions.
