Unicystic ameloblastoma is a distinguishable entity of ameloblastomas, characterized by slow growth and being relatively locally aggressive. Three histological types are recognized according to the degree of ameloblastomatous epithelial extension, namely, luminal, intraluminal, and mural types. This classification has a direct bearing on their biological behavior, treatment, and prognosis. However, there is difficulty in determining the most appropriate form of treatment for unicystic ameloblastoma. We present a case of unicystic ameloblastoma that occurred in the right posterior mandible of 19-year-old girl, which was enucleated and did not recur after 12-month follow-up.

Purpose: Current standard of care for ameloblastoma (conventional/unicystic - mural type) usually mandates extensive bone resection that frequently necessitates immediate reconstruction with serious sequelae, especially among young patients. BRAF-mutated ameloblastomas can be targeted by BRAF inhibitors to markedly reduce their size, enabling conservative removal of residual tumor. We aimed to characterize the effect of post-treatment histomorphologic changes.

Odontogenic cysts and tumors exhibit a broad spectrum of biological characteristics. Despite recent advances in understanding the complex nature of these lesions, relatively less is known about the molecular markers involved in key pathogenic steps, such as proliferation and differentiation. This study aimed to elucidate the expression patterns of p63 and Ki-67 in odontogenic lesions, which may influence the management strategies.

Glandular odontogenic cysts(GOC) are among the rarest odontogenic cysts defined by the presence of glandular epithelium in the epithelial lining posing some diagnostic difficulties. GOC associated with ameloblastoma is extremely rare with only 5 cases reported. This report deals with this rare occurrence of GOC along with unicystic ameloblastoma.

Ameloblastoma is a true benign odontogenic epithelial tumor, primarily arising in the jaw, and ranks as the second most prevalent odontogenic neoplasm following odontoma. Known for its diverse clinical, radiographic, and histological manifestations, ameloblastoma encompasses a wide spectrum of presentations. Unicystic ameloblastomas (UAs), a less common and generally less aggressive variant, appear as cystic lesions that can mimic ordinary jaw cysts in their clinical and radiologic features.

The most common odontogenic tumor is the solid ameloblastoma. This is concerning due to the progressive bone destruction in its intraosseous variant; this type of pathology often gets a delayed diagnosis due to the asymptomatic characteristic it has. The aim of the article is to propose a conservative treatment for multicystic ameloblastoma, reviewing the latest concepts, controversies, and treatment options described in the literature.
