Actinomyces-associated calcifications in a dentigerous cyst of the mandible.

Actinomyces-associated lesions in the jaw, such as radicular cyst and osteomyelitis, have been reported by many authors. The lesions are caused by infection from peripheral sites and can be seen to contain Actinomyces druses on pathologic examination. To our knowledge, no previous reports have described Actinomyces-associated calcification in the jaw, although the lesions in the jaw often include druses.

Cartilaginous choristoma of the lower lip.

Choristoma is a tumor-like mass consisting of normal cells in an abnormal location. Cartilaginous choristoma, which is composed of ectopic cartilaginous tissue, very rarely presents in the oral cavity and most commonly in the tongue. Here we report an extremely rare case of cartilaginous choristoma of the lower lip.

Osteosynthesis and simultaneous irregular trifocal distraction osteogenesis for segmental mandibular defect after tumor ablative surgery: a case report.

Objective: This paper describes a case of secondary mandibular bone reconstruction performed to place dental implants. Osteosynthesis and simultaneous irregular trifocal distraction osteogenesis were documented.

Patient: The patient was a 51-year-old man with recurrent ameloblastoma of the mandible.

Salivary duct carcinoma in the mandible: a case report.

Salivary duct carcinoma (SDC) is a distinctive and aggressive neoplasm. The most frequent site of origin is the parotid gland, followed by the submandibular gland. SDC originating in the minor salivary glands, particularly in the ectopic glands within the mandible, is extremely rare.
