Glanduläre odontogene Zyste des Unterkiefers

Abstract

Due to rare occurrence and similarity to botryoid odontogenic cyst and low-grade mucoepidermoid carcinoma GOC is difficult to identify. It remains without clinical signs for years and is identified in routine X-rays in most cases. We recommend cystectomy after use of Carnoy's solution for intravital fixation. No filling material is required for complete bony healing.

Glandular odontogenic cyst: a case report

“…Moreover, there remains a lack of clarification on some issues, such as histogenesis, biological behaviour and the appropriate treatment of these lesions. The present case report is in agreement with most cases cited in the literature 2,5,8 , which consider the anterior region of the mandible the most affected area. Contrarily, Qin et al 9 reported a series of cases with a greater prevalence of lesions in the anterior region of the maxillary.…”

“…The definitive diagnosis of GOC cannot be performed by radiographic exams because of the similarities with the various intrabone pathologies mentioned above 8 . Thus, the majority of the authors 1,2,6,8,9 stress the importance of a histological evaluation of all cases. In fact, lateral periodontal cysts may also present histological findings described as ‘circular nodules’ on epithelial layer surface 11 , but the later should not reach bigger dimensions or provoke clinical swellings.…”

“…The term glandular odontogenic cyst (GOC) has been proposed as the most appropriate designation for this rare pathological lesion 1 . It was formerly denominated mucous‐producing odontogenic cyst and sialo‐odontogenic cyst because of a probable origin from the tissue which forms the salivary glands 1,2 . Binda et al.…”

“…The main published features include the presence of a radiolucent swelling in the jaws, a tendency towards local recurrence after conservative surgical treatment. Some lesions can grow slowly and remain small, others may reach larger dimension, infiltrate and destroy the bone 2,3,5,7 . Radiography reveals a unilocular or multilocular radiolucent image with well‐defined margins.…”

“…According to the literature 2,3 , GOC's histopathological characteristics comprise: cystic cavity lined with stratified squamous epithelium of variable thickness; the absence of inflammatory infiltrate in the capsular conjunctive tissue; and surface layer of the epithelium may present areas of cuboidal eosinophilic cells, or ciliated cells. Sometimes an irregular papillary surface can be identified.…”
