A rare case report: calcifying odontogenic cyst mimicking lateral periodontal cyst with 1-year Follow-up.

ABSTRACT:

Background

Lateral periodontal cyst (LPC) and calcifying odontogenic cyst (COC) represent diagnostically challenging odontogenic lesions due to overlapping clinical and radiographic features. However, COC is exceptionally rare in periodontal tissues with only one case reported in the literature.

Case presentation

In this case, a 35-year-old male presented with an asymptomatic gingival swelling between teeth #22 and #23. Initial clinical examination revealed a 1.5 cm x 1 cm firm, translucent swelling with deep periodontal probing depths (PD) (14-15 mm). Radiographic evaluation demonstrated a well-circumscribed radiolucency between vital tooth roots, initially suggestive of LPC. However, histopathological analysis identified characteristic ghost cells and dystrophic calcificat
