Rare example of the use of fine‐needle aspiration cytology for periapical osseous dysplasia

Abstract

Osseous dysplasia (OD) is one of the fibro-osseous jaw lesions characterized by cellular fibrous tissue with hard tissue formation. We report a rare fine-needle aspiration cytology (FNAC) for periapical OD. A 34-year-old woman had well-defined, round, mixed radiolucent lesions in the periapical regions of the bilateral mandibular canines. FNAC showed hypocellular with some multinucleated giant cells and a few clusters of fibroblastlike cells. These cells had bland nuclei, with no nuclear atypia or mitotic figures. No calcified materials or bony spicules were evident. Microscopically, the lesions consisted of cellular fibrous tissue and hard tissue. The final diagnosis was bilateral periapical OD. FNAC alone may not be an accurate procedure for definitive diagnosis of a fibro-osseous lesion, but it can be a useful and reliable diagnostic method when used in conjunction with clinical and imaging findings.

Intraoral and Oropharyngeal Lesions: Role of Fine Needle Aspiration Cytology in the Diagnosis

“…Fibro-osseous lesions of the jaw comprise of a spectrum of diseases which include osseous dysplasia, fibrous dysplasia, and ossifying fibroma [21]. FNA smears show clusters of fibroblast-like cells with bland nuclei, and no nuclear atypia or mitotic figures along with some multinucleated giant cells.…”

Fibrous dysplasia of the nasal bone: case reports and literature review

“…Fine needle aspiration cytology has been shown to be a useful diagnostic adjunct in lesions around the sinonasal region, mainly to exclude a more sinister pathology. 3,4 While fibrous dysplasia has been shown to affect a number of bones in the craniofacial region, involvement of the nasal bones in isolation has never been described. We describe two such cases and highlight the different management options.…”

“…Most commonly, the diagnosis of fibrous dysplasia is made radiologically, with the classical ground-glass appearance seen on computed tomography (CT) imaging. Fine needle aspiration cytology has been shown to be a useful diagnostic adjunct in lesions around the sinonasal region, mainly to exclude a more sinister pathology 3 , 4 …”
