Background: The glandular odontogenic cyst is a rare jawbone cyst that is considered to be an independent entity, although its histopathological characteristics may lead to an incorrect diagnosis as a low-grade mucoepidermoid carcinoma. The treatment of glandular odontogenic cysts is controversial.
Case Report: We present two high-risk cases treated with conservative approaches, one by enucleation and curettage and the other by marsupialisation. This report also presents a review of the clinical and pathological aspects of glandular odontogenic cysts, and considers their development. No evidence of disease was observed after 3 years of follow-up in the two cases presented.
Conclusions: When possible, treatment plans for these lesions should be customised for each case, taking into account the data available in the literature and patient preferences. For high-risk cases, that are treated with conservative approaches, such as the two cases presented here, strict and regular controls and rigorous radiological follow-up evaluations are mandatory.

Objective: The study aimed to investigate the expression of hypoxia markers associated with invadopodia in glandular odontogenic cysts and to explore an association between this expression with the aggressive biological behaviour of this odontogenic cyst.
Design: Immunohistochemistry was employed to assess the expression of hypoxia-inducible factor 1 alpha (HIF-1α), notch homologous protein of the neurogenic locus 1 (NOTCH-1), disintegrin and metalloproteinase-12 (ADAM-12), and heparin-binding epidermal growth factor (HB-EGF) in 17 samples of glandular odontogenic cysts, 10 samples of calcifying odontogenic cysts, and 10 samples of dental follicles.
Results: The glandular odontogenic cyst samples exhibited increased expression of HIF-1α, NOTCH-1, ADAM-12 and HBEGF proteins compared with calcifying odontogenic cyst and dental follicle samples.

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.

Central mucoepidermoid carcinoma is a relatively rare salivary gland tumour of the jawbone. Glandular odontogenic cyst is another unique odontogenic developmental cyst characterised by glandular differentiation. Both entities share several histological characteristics, and a pre-existing Glandular odontogenic cyst can evolve into Central mucoepidermoid carcinoma.

Article Synopsis
- The case involves a 76-year-old male who received multiple endodontic treatments for a misdiagnosed glandular odontogenic cyst, which was initially mistaken for an inflammatory periapical lesion.
- Glandular odontogenic cysts are known to be more aggressive compared to other types, and there's a lack of extensive research on this in older dental patients.
- The correct diagnosis was confirmed through a biopsy, leading to successful surgery while ensuring the base of the mandible was preserved, emphasizing the need for careful diagnosis in elderly patients.
