ABSTRACT
The keratocystic odontogenic tumor (KCOT), formerly known as odontogenic keratocyst, is a benign developmental odontogenic tumor with many distinguishing clinical and histologic features. Hard tissue deposits, which usually take the form of dystrophic calcifications, cartilaginous tissue, or dentinoid, are uncommon findings in the connective tissue capsule of the KCOT. We report a case of a 33‑year‑old female with KCOT showing osseous tissue and calcified deposits close to its epithelial lining, which is an extremely rare occurrence. A brief review on the reported prevalence of hard tissue deposits in KCOTs and possible mechanisms that has been implicated in mineralization and bone formation has been discussed.
ABSTRACT
Lipomas are benign soft tissue mesenchymal neoplasms. Fibrolipoma is a histological variant of lipoma that mostly affects the buccal mucosa and causes functional and cosmetic disabilities. The diagnosis and differentiation of fibrolipoma with clinically similar lesions such as fibroma and pleomorphic adenoma is very essential for a correct treatment plan and complete follow-up. This article presents a case of a 35-year-old female with a fibrolipoma on the lingual marginal gingiva of the mandibular left third molar.
