A case of metastatic bronchogenic carcinoma to the gingiva in a 47-year-old male is reported. The gingival lesion developed as a quickly growing mass and appeared 2 months after surgical excision and radiotherapy of the lung carcinoma were completed. The gingival tumor was histopathologically diagnosed as a poorly differentiated squamous carcinoma. Comparative cytologic studies showed similarities between the gingival metastasis and the previous lung cancer.

A cementifying fibroma associated with a large intraosseous periodontal defect is reported. This tumor was located in the lingual aspect of the first lower left molar. Therapy consisted on flap surgery, tumor excision, and placement of a bone autograft in order to fill the residual bone defect. Six months after the treatment, clinical and radiographic signs of periodontal regeneration were evidenced.
