A Calcifying Odontogenic Cyst Associated with Compound Odontoma Mimicking a Tooth Germ

Peripheral calcifying odontogenic cyst: a case report and comprehensive review of 60 years of literature

Peripheral Calcifying Odontogenic Cyst (PCOC) is the extraosseous form of calcifying odontogenic cyst that is limited to peripheral soft tissue without bony involvement. This case report presents a case of PCOC manifested as a progressive growth of gingival mass in a young male treated with excisional biopsy. Histological examination confirmed diagnosis of PCOC with presence of characteristic ghost cells and sporadic calcifications. No recurrence of the lesion and no complication were noted at three-year follow-up. Review of available literature on PCOC noted a predilection of occurrence in the mandible (61%) and in the anterior area of the jaws (58%). Mean age of patients was 41.7 ± SD25.43 (7-83) and 95% CI [33.6, 49.8] yrs. Mean size of the lesions was 1.38 ± SD1.1 (0.5-4.3) and 95% CI [0.93, 1.83] cm. Gender distribution was noted to be 51.3% male and 48.7% female.

Mystery Behind a Broken, Discolored Right Maxillary Central Incisor: A Case Report

Odontoma is a hamartomatous benign odontogenic tumor that may resemble tooth-like structures. Odontomas can impede the eruption of the permanent underlying tooth or can cause devitalization of the tooth resulting in pain and swelling near the tooth, causing diagnostic dilemmas to the dentist. We describe a case of an unusual occurrence of such an odontoma in a 31-year-old male patient in the periapical region of a broken, discolored maxillary central incisor tooth causing a diagnostic dilemma and its treatment.

Calcifying odontogenic cyst: Report of an uncommon entity with a brief literature review

The aim of this clinical report is to document a rare and unusual case of calcifying odontogenic cyst (COC) in the maxillary anterior region in a 13-year-old girl.

A COC is an extremely uncommon developmental, odontogenic entity and accounts for 0.3%–0.8% of odontogenic cysts. The lesion presents as an array of varied radiographic and clinicopathological characteristics and biological attributes and exists in three histomorphologic patterns – benign cystic, solid (neoplastic) and aggressive (malignant) forms. Thus, several nomenclatures and classifications have been put forth to explain the nature of the clinical entity. However, ambiguities regarding the exact nature of the lesion still prevail. Due to nonspecific clinicoradiographic features, histopathological interpretation remains the key for diagnosis. We report an uncommon occurrence of COC in a 13-year-old female who reported to our Outpatient Department with an asymptomatic right midfacial swelling. The clinical and radiographic findings were suggestive of adenomatoid odontogenic tumor and dentigerous cyst. The decision to enucleate the lesion was considered, and histopathological features were compatible with the diagnosis of COC. Re-ossification with no recurrence was noticed after a 1-year follow-up. COC is an unusual developmental odontogenic cyst that clinically and radiologically simulates other more common jaw entities. Thorough knowledge of the bizarre presentation and biological attributes of such lesions are imperative for an early diagnosis and definitive treatment. Long-term follow-up is advocated to prevent recurrences.
