The aim of the present review was to integrate the available data published on gingival cyst of the adult (GCA), lateral periodontal cyst (LPC), and botryoid odontogenic cyst (BOC) into a comprehensive analysis of their clinical/radiological features. An electronic search was undertaken in July/2017. Eligibility criteria included publications having enough clinical/radiological/histological information to confirm the diagnosis. A total of 146 publications (157 GCAs, 213 LPCs, 96 BOCs) were included. GCA and LPC presented highest prevalence in the sixth/fifth decades; BOC in the sixth/seventh decades. LPCs were larger lesions than GCAs and GCAs appeared at an older age than LPC. There was no statistically significant difference between them for other factors (location, symptoms, recurrence, follow-up time). In comparison with LPC, BOC lesions were larger, appeared more often in mandible and in older subjects, had more often a multilocular appearance, and presented a higher recurrence rate. Recurrence rates: GCA (3.2%), LPC (2.4%), BOC (21.7%). No factor seems to influence the recurrence rate of GCA or LPC. Multilocular radiological appearance seems to affect the recurrence rate of BOCs. Conservative surgical approaches seem to be enough for GCA/LPC. BOC presents a more aggressive behavior than GCA/LPC. Therefore, treatment of this lesion might involve some kind of adjunctive therapy after enucleation.

Review
Lateral periodontal cyst, developmental in origin, typically is observed in the cuspid-bicuspid region of the mandible and less frequently in the maxilla. It may arise initially as a dentigerous cyst developing by expansion of the follicle along the lateral surface of the crown which eventually comes to lie on the lateral aspect of the root if tooth eruption is normal. Alternatively, it may arise from the cell rests of malassez. The incidence of lateral periodontal cysts has been reported to be less than 1% and these cysts represent nearly 0.8% of all central cysts of the maxillary bone. Here we present one such case with unusual findings.

BACKGROUND
Lateral periodontal cyst (LPC) is an uncommon form of developmental odontogenic cyst. LPC can be suspected when there is a round, well-circumscribed radiolucency, usually of small diameter, along the lateral surface of vital erupted teeth, predominantly in the mandibular premolar region. Histopathological analysis allows LPC to be diagnosed based on its characteristic features such as a thin cuboidal to stratified squamous non-keratinizing epithelium containing epithelial plaques and glycogen-rich clear cells. The aim of this article was to report two cases of atypical LPC associated either with an impacted lower left canine (tooth #33) or with a lower right third molar (tooth #48).
CASE PRESENTATION
Case 1: A 56-year-old man was referred to us for an oro-dental assessment. Panoramic radiography revealed an impacted lower left permanent canine (tooth #33) with well-defined radiolucency on its upper cervical margin. A CT scan revealed a pericoronal radiolucency of 5 mm at its widest diameter around the impacted tooth #33. The pericoronal tissue was removed and sent for histopathological examination. The results revealed a lateral periodontal cyst. Satisfactory postoperative healing was achieved at the site. Follow-up at 12 months indicated no recurrence of the lesion. Case 2: A 54-year-old woman consulted with the main issue being pain on the lower right side of the face. Intra-oral examination revealed a vestibular swelling involving the region of the second molar (tooth #47), with obliteration of buccal sulcus. Pocket depth was determined to be 9 mm at the distal of #47. A diagnosis of gingival abscess resulting from chronic periodontitis was made. Panoramic radiography revealed a radiolucent cystic lesion associated with an impacted horizontal lower right third molar (tooth #48), suggestive of a dentigerous cyst. X-rays also revealed alveolar bone resorption on the molar (tooth #47). The cyst was removed along with the third molar and submitted for histopathological diagnosis. The diagnosis was LPC. Follow-up at 18 months indicated no recurrence of the lesion.
CONCLUSION
These cases represent atypical presentations of LPC. They provide examples of the differential diagnosis of pericoronal radiolucencies involving an impacted tooth and our observations provide insights regarding the pathogenesis of LPC.

Review
OBJECTIVE
To report a case of lateral periodontal cyst (LPC) with marked melanin pigmentation in a 38-year-old Black male and to discuss the phenomenon of melanin pigmentation in odontogenic cysts and tumors.
RESULTS
Histologically, the epithelial lining of the LPC contained an abundant amount of melanin granules throughout the entire epithelium. Ultrastructurally, epithelial cells contained mature melanosomes (stage IV melanosomes). Melanophages containing aggregates of melanosomes were identified in the connective tissue cyst wall. Perusal of the literature revealed that melanin pigmentation in odontogenic lesions is uncommon. Melanin has been reported in calcifying odontogenic cyst (18 cases), odontogenic keratocyst (8 cases), adenomatoid odontogenic tumor (3 cases), ameloblastic fibroma (3 cases), odontoma (2 cases), and ameloblastic fibro-odontoma, odonto-ameloblastoma, and odontogenic fibroma (1 case each).
CONCLUSIONS
Almost all pigmented odontogenic lesions; occurred in Blacks and Asians; they are almost non-existent in Whites. Thus, racial pigmentation probably plays an important role in such lesions.

Review
INTRODUCTION
Buccal bifurcation cyst is an inflammatory odontogenic cyst and constitutes up to 5% of all odontogenic cysts. The aim of this study was to report a series of cases, review the recent literature, and facilitate recognition and proper treatment of this entity.
METHODS
With institutional review board approval, the authors retrieved all archival cases of buccal bifurcation cyst from the oral pathology biopsy service from 1994 through 2018. Patient age and sex, cyst location, clinician's impression, radiographic appearance, diagnosis, and treatment data were recorded.
RESULTS
A total of 10 cases were identified. Average patient age was 9 years. A slight male predilection was observed (n = 6, 60%). One hundred percent of cases were in the mandible, including 3 (30%) bilateral cases.
CONCLUSIONS
Mandibular buccal bifurcation cyst is an important entity in pediatric patients but may be less likely to be recognized by clinicians not regularly treating children. The results of this study are mostly consistent with the literature. Treatment is typically via enucleation or even more conservative modalities, and extraction should be avoided if possible.
PRACTICAL IMPLICATIONS
Buccal bifurcation cysts should be treated via enucleation or even more conservative methods. If possible, the affected teeth should be preserved.

The lateral periodontal cyst is of developmental odontogenic origin and must be differentiated from the gingival cyst of adults, a primordial cyst in a lateral periodontal position, and a cyst of inflammatory origin. This paper is based on a histologic study of five cases. Four were in the mandibular premolar region and one in the lateral incisor-canine region of the maxilla. The cysts are lined by a thin non-keratinized epithelium which resembles the reduced enamel epithelium. Many of them arecharacterized by the presence of localized plaque-like thickenings of their epithelial linings, consisting of fusiform or large swollen, edematous cells. These epithelial thickenings appear to result from a localized proiferation of basal cells. The lateral periodontal cyst may arise initially as a dentigerous cyst which develops by expansion of the follicle along the lateral surface of the crown and comes to lie on the lateral aspect of the root if tooth eruption is normal. Alternatively, it may arise from the cell rests of Malassez.

INTRODUCTION
Radiolucent lesions with gingival swelling found in the premolar and intercanine region can elicit a different clinical diagnosis than one confirmed by histologic findings. The purpose of the study is to identify and present the frequency of the unexpected microscopic diagnosis of odontogenic keratocyst (OKC) in a location preoperatively favoring a lateral periodontal cyst (LPC) with similar clinical and radiographic appearance.
METHODS
A retrospective analysis of biopsies received from 2011 and 2019 was performed, and the number of LPC and OKC cases was assessed. The alignment of clinical and radiographic diagnosis to histologic findings and anatomic location was analyzed, and the number of OKC cases preoperatively misdiagnosed as LPCs was identified.
RESULTS
A total of 79,257 biopsies were received. Of those, 184 were diagnosed as LPCs and 742 as OKCs. For all preoperatively diagnosed LPCs, the clinical and histologic diagnosis aligned; however, 182 of 742 OKCs were submitted with a clinical misdiagnosis of LPCs. The location of these lesions with the unanticipated diagnosis overlapped with those for LPCs, specifically the maxillary and mandibular anterior and premolar regions.
CONCLUSIONS
Radiolucent lesions with gingival swelling in the premolar and intercanine region are frequently clinically and radiographically misdiagnosed. A biopsy should be considered in all cases to establish the correct pathologic diagnosis and treatment course.
