A differential diagnosis is also possible where DCs can be distinguished from odontogenic keratocyst
, ameloblastic fibroodontoma, ameloblastic fibroma, calcifying epithelial odontogenic tumor, adenomatoid odontogenic tumor, and unicystic ameloblastoma (7).
Odontogenic tumours like Ameloblastoma and Odontogenic Keratocyst
(OKC) can pose diagnostic challenges because of their overlapping clinical, radiographic and histopathological presentation.
Key Words: Impacted third molars, unerupted teeth, pathologies, dentigerous cyst, odontogenic keratocyst
(OKC) is officially known as a true benign tumor, and it is aggressive in nature.
A provisional diagnosis of the periapical cyst, odontogenic keratocyst
, dentigerous cyst, and unicystic ameloblastoma was arrived at.
The differential diagnosis includes a dental follicle, an eruption cyst (a soft-tissue cyst overlying the erupting tooth), a glandular odontogenic cyst, and a unicystic ameloblastoma, while an odontogenic keratocyst
may also be considered.
Clinical and radiological presentation of the brown tumor can mimic other diseases, the most likely diagnoses include odontogenic and nonodontogenic cysts and tumors (radicular cyst, lateral periodontal cyst, ameloblastoma, keratocyst
, eosinophilic granuloma, giant cell lesions, myxoma, and fibroosseous lesions), infectious diseases (bone abscess and localized osteomyelitis), and metastasis from a known or an unknown primary site (lung, breast, kidney, and prostate) [9, 10].
Unicystic ameloblastoma (UA) and odontogenic keratocyst
(OKC) are benign but locally invasive lesions.
The histopathological appearance of a biopsy specimen was consistent with the odontogenic keratocyst
(OKC) (Figures 3(a) and 3(b)).
The differential diagnosis of AOT from other lesions similar to AOT (e.g., dentigerous cyst, keratocyst
odontogenic tumors, unicystic ameloblastoma, and calcifying cystic odontogenic tumors) in radiographic findings may be difficult.
Dentigerous cyst and odontogenic keratocyst
may possibly be the clinical differential diagnosis considering the age, site, size, and extent of the swelling.
is managed by complete removal in one piece which is often difficult because it has a thin, friable cystic wall.
