MORENO, Emilio; LOLAS M, Jorge; VERGARA, Alfonso  e  MARQUEZ, Agustin. Follicular inflammatory cyst in atypical location: Case report and literature review. Rev. Estomatol. Herediana [online]. 2017, vol.27, n.3, pp.191-201. ISSN 1019-4355.  http://dx.doi.org/10.20453/reh.v27i3.3203.

Objectives: To show the importance of histopathology in the diagnosis of follicular inflammatory cyst for a correct treatment and the relevance of a precise nomenclature. Material and Methods: Pubmed search, ScienceDirect, EBSCO-host “odontogenic cysts”, “inflammatory dentigerous cyst” and “follicular inflammatory cyst” as keywords, full text in English or Spanish for the last 10 years. Results: A 10-year-old patient presented vestibular tumor of the tooth area 5.3, with a hard consistency, asymptomatic and covered by normal mucosa. Associated tooth without carious lesions. The radiograph evidenced a radiolucent area with well-defined limits, around the crown of the tooth 1.3, displacing and retaining it. After radiographic evaluation, the differential diagnoses were tumor-odontogenic-adenomatoid, keratocyst and QD. Histopathology confirmed QFI. Originating the lesion from piece 5.4 with pulp treatment. Conclusions: The QFI should be considered as an similar to other inflammatory (paradental or root) cysts. It is suggested to consider in mixed dentition, that QFI and radicular cyst of the temporal tooth are the same lesion and the differences in their clinical aspect will depend on the evolution time and the proximity relation between follicle and inflammatory process of temporal temporal.
