Palpatory findings elicited a non-tender, firm-hard consistency swelling with no increase in the surface temperature [Figures 1(a) and 1(b)]. Palpatory features were suggestive of a non-tender swelling, with peripheral firm consistency and central fluctuations [Figure 1(c)].
(a) Fine-needle aspiration revealed yellow-brown, blood-tinged cystic aspirate. (b) and (c) IOPAR and OPG demonstrate a well-defined unilocular radiolucency with an impacted inverted mesiodens in the maxillary anterior region.

Fine-needle aspiration yielded a brownish-yellow, blood-tinged cystic aspirate [Figure 2(a)]. Root resorption of teeth #21 and #22 with distal flaring of the roots of teeth #11 and #21 was also noticed [Figure 2(b)]. The floor of the left maxillary sinus was slightly pushed superiorly, and a slight distal displacement of the roots of teeth 11 and 21 with root resorption of teeth #21, #22, #24, and #25 was also apparent [Figure 2(c)].

Sutures were placed, and the enucleated specimen was sent for histopathologic evaluation [Figures 3(a), 3(b), and 3(c)].
(a) and (b) Epithelial lining showing a combination of pseudostratified ciliated columnar and nonkeratinized stratified squamous epithelium varieties, with mucous glands and neurovascular bundles in the cystic wall (H&E stain, 100x).
