INTRODUCTION

The botryoid odontogenic cyst (BOC) is a rare lesion, described by Weathers, Waldron in 197311. Weathers D, Waldron C. Unusual multilocular cysts of the jaw (botryoid odontogenic cysts). Oral Surg Oral Med Oral Pathol. 1973;36(2):235-41.. Its main characteristics are the typical multilocular aspect, similar to a bunch of grapes, justifying its terminology (botryoid: from the greek botrys= bunch of grapes; oeides= in a shape of), commonly affecting the mandible bicuspid and canine region without symptoms. Other evidences suggest the possibility of this lesion represent a variation of the lateral periodontal cyst (LPC), promoting discussion and doubt among authors.

This paper presents a case report of this rare and polemic odontogenic cyst, contributing to the small number of publications of this pathology in the literature. Moreover a discussion with focus on its etiopathogenic, diagnostic and therapeutic considerations is presented by the authors.

CASE REPORT

A male, 44 years old, melanoderma, came up complaining of a swelling in the anterior left region of the mandible for already two months. The intra-oral examination showed a discreet but consistent and hard swelling adjacent to the canine without alterations in the local mucosa. Periapical and oclusal radiographies demonstrated a radiolucent multilocular image of approximately 20 mm over the canine root with extension to the adjacent incisive teeth (Figures 1 and 2). Dental vitality test showed positive result of the mentioned teeth, discarding inflammatory origin. Considering the possibility of a BOC, an excisional biopsy using enucleation followed by peripheral ostectomy technique was performed.

During surgery, strong adhesion of the cystic capsule to the canine root was observed. The surgical specimen was sent to histopathologic examination in which was observed a multilocular lesion 15 x 17 mm, characterized by multiple cysts and separated by discreet connective tissue septa associated to the capsule (Figure 3). The epithelial boundary of these small cysts showed regions of nodular enlargement composed by glycogen-rich clear cells (Figure 4). In face of this, the final diagnosis was of a BOC.

After 15 days, a new dental vitality test was accomplished and the canine vitality was maintained. Postoperative periapical radiography taken after 60 days demonstrated normal bone healing process. The patient continues in follow-up in case of any recurrence is observed.

DISCUSSION

There are many doubts related to the etiopathogenesis of the BOC and its condition as an individual entity. The hypothesis of such lesion representing a multilocular variation of the LPC is defined by some authors based in clinical and histopathologic similarities11. Weathers D, Waldron C.

Both present predilection to the inferior canine and bicuspid region, as presented in the present case, and demonstrate epithelium with clear cells nodule33. Shear M, Pindborg JJ.

.

It is believed that the BOC and the LPC have the same origin, although the type of odontogenic epithelium is debated. The participation of the reduced enamel epithelium or the epithelium rests of Malassez was suggested in the etiopathogenesis of these lesions33. Shear M, Pindborg JJ. Microscopic features of the lateral periodontal cyst. Scand J Dent Res. 1975;83(2):103-10.. However, recent publications defend the cystic degeneration of dental lamina rests, found in the alveolar ridge, in function of the observed histopathologic characteristics44. Carter LC, Carney YL, Perez-Pudlewski D. Lateral periodontal cyst: multifactorial analysis of a previously unreported series. Oral Surg Oral Med Oral Pathol Oral Radiol Endod. 1996;81(2):210-6.. The determining point that supports this theory is the presence of clear cells in the epithelial boundary of these cysts, similar as in the dental lamina. On the other hand, those cells are not identified in dentigerous and radicular cysts, which present etiopathogenesis related to the reduced epithelium and the epithelium rests of Malassez, respectively.

The histopathologic characteristics of the BOC are quite similar to the LPC, differing only in the multilocular aspect. Multilocular lesions are characterized by the presence of cavities, cystic or not, separated by connective or osseous septa. In the case of the BOC, cystic cavities of different sizes and quantities are limited by fine connective tissue septa contiguous to the capsule. Such aspect is explained by epithelium nodule growth towards the capsule, with subsequent cystic degeneration11. Weathers D, Waldron C. Unusual multilocular cysts of the jaw (botryoid odontogenic cysts). Oral Surg Oral Med Oral Pathol. 1973;36(2):235-41., or by new cysts formation from the proliferative stimulation of adjacent epithelium remnants44. Carter LC, Carney YL, Perez-Pudlewski D. Lateral periodontal cyst: multifactorial analysis of a previously unreported series. Oral Surg Oral Med Oral Pathol Oral Radiol Endod. 1996;81(2):210-6.-55. Üçok Ö, Yaman Z, Günhan Ö, Üçok C, Dogan N, Baykul T. Botryoid odontogenic cyst: report of a case with extensive epithelial proliferation.

https://doi.org/10.1016/j.ijom.2005.01.0...
. Although this characteristic is essential to the histopathologic diagnosis of the BOC, the eventual damage of this aspect during surgery or by laboratorial manipulation may difficult its differentiation from the LPC66. Lindh C, Larson A. Unusual jaw-bone cysts. J Oral Maxillofac Surg. 1990;48(3):258-63. doi:10.1016/0278-2391(90)90390-N

.

The BOC generally occurs in older patients and shows greater proportions that the LPC, being sometimes observer in edentulous patients22. Mendes RA, van der Wall I. An unusual clinicoradiographic presentation of a lateral periodontal cyst--report of two cases. Med Oral Patol Oral Cir Bucal. 2006;11(2):185-7.,55. Üçok Ö, Yaman Z, Günhan Ö, Üçok C, Dogan N, Baykul T. Botryoid odontogenic cyst: report of a case with extensive epithelial proliferation. Int J Oral Maxillofac Surg. 2005;34(6):693-5. doi:10.1016/j.ijom.2005.01.005
https://doi.org/10.1016/j.ijom.2005.01.0...
. Although these differences indicate a distinction between these two entities, a critical analysis is necessary. As the development of a multilocular lesion presents slow growth, a LPC not diagnosed in the youth may present later, between the fifth and seventh decades, larger and with a botryoid aspect, as described in the literature44. Carter LC, Carney YL, Perez-Pudlewski D. Lateral periodontal cyst: multifactorial analysis of a previously unreported series. Oral Surg Oral Med Oral Pathol Oral Radiol Endod. 1996;81(2):210-6.,77. Gurol M, Burkes EJ, Jacoway J. Botryoid odontogenic cyst: analysis of 33 cases. J Periodontol. 1995;66(12):1069-73. doi:10.1902/jop.1995.66.12.1069
https://doi.org/10.1902/jop.1995.66.12.1...
. The possibility of identification of a BOC in edentulous areas also does not mean much since a residual LPC may continue its development after the extraction of the adjacent teeth.

For all of above mentioned reasons, we consider that the BOC and the LPC are a unique nosologic entity in different periods of evolution. However, we believe that is necessary to classify the variant botryoid due to its apparently higher recurrence rate and for its necessary treatment peculiarities. Although the recurrence rate is presented between 15 and 30%, the presented incidence number is low to determine confident data44. Carter LC, Carney YL, Perez-Pudlewski D. Lateral periodontal cyst: multifactorial analysis of a previously unreported series. Oral Surg Oral Med Oral Pathol Oral Radiol Endod. 1996;81(2):210-6.-55.

. In these studies, recurrence is observed around ten years after enucleation.

Even tough some reports point out the proliferative behavior of the BOC, it is believed that the recurrences are related to the difficulty to the complete removal of the lesion due to its multilocular aspect and its thin capsule55. Üçok Ö, Yaman Z, Günhan Ö, Üçok C, Dogan N, Baykul T. Botryoid odontogenic cyst: report of a case with extensive epithelial proliferation. Int J Oral Maxillofac Surg. 2005;34(6):693-5. doi:10.1016/j.ijom.2005.01.005

https://doi.org/10.1016/0278-2391(88)901...
. This idea is supported in the histopathologic finds of Phelan et al.99. Phelan JA, Kritchman D, Fusco-Ramer M, Freedman PD, Lumerman H. Recurrent botryoid odontogenic cyst (lateral periodontal cyst). Oral Surg. 1988;66(3):345-8. doi: 10.4103/0976-237X.103629
https://doi.org/10.4103/0976-237X.103629...
, that showed microcysts in the capsule of recurred LPCs (which perhaps could classified as BOC due to its multilocular aspect).

To accomplish the therapeutic of the BOC, the complementary treatment of the surgical bed may be used after enucleation. As alternatives, the peripheral ostectomy or Carnoy solution application fit perfectly in order to eliminate possible remnants of this lesion1010. Lee PK, Samman N, Ng IO. Unicystic ameloblastoma: use of Carnoy's solution after enucleation. Int J Oral Maxillofac Surg. 2004;33(3):263-7. doi:10.1006/ijom.2003.0496

Although the diagnosis of the BOC is only confirmed after histopathologic examination, clinical, radiographic or macroscopic characteristics suggestible of this lesion may help in the indication of complementary treatment modalities during surgery. Even with the use of the techniques, we suggest follow-up for a long period due to the scarce scientific knowledge related to this odontogenic cyst.

CONCLUSION

The etiopathogenesis of the BOC seems to be related to the degeneration of the dental lamina rests, as nowadays accepted for the LPC. Both lesions have similar characteristics and may represent the same nosologic entity in distinct evolution periods. The tendency for recurrence presented by the botryoid variant might be controlled by surgical complementary approaches, like peripherical ostectomy and application of Carnoy Solution.
