Unusual peripheral odontogenic tumors in the differential diagnosis of gingival swellings

Abstract

Abstract. Differential diagnosis of gingival mass lesions includes several conditions and causes. Peripheral odontogenic tumors may mimic gingival swellings and, although rare, must be included in the differential diagnosis. The purpose of this article is to describe 3 different cases of peripheral odontogenic tumors and to discuss the differential diagnosis of gingival swelling. Histologic examination is mandatory when localized gingival swellings are surgically removed. Zusammenfassung Ungewöhnliche periphere odontogene Tumoren bei der Differentialdiagnose von Gingivaschwellungen Die Differentialdiagnose von Gingivaläsionen schließt verschiedene Befunde und Ursachen ein. Periphere odontogene Tumoren können Gingivaschwellungen imitieren und sie müssen, obwohl sie selten sind, in die Differentialdiagnose einbezogen werden. Der Zweck dieses Artikels ist es drei verschiedene Fälle von peripheren odontogenen Tumoren zu beschreiben und die Differentialdiagnose von Gingivaschwellungen zu diskutieren. Die histologische Untersuchung ist zwingend notwendig, wenn die lokalisierten Gingivaschwellungen chirurgisch entfernt werden. Résumé Tumeurs odontogènes périphériques rares et diagnostic différentiel des intumescences de la gencive Le diagnostic différentiel des lésions de la masse gingivale comprend des affections et des causes sévères. Les tumeurs odontogènes périphériques peuvent avoir l'aspect d'intumescences de la gencive, et bien qu'elles soient rares, elles doivent être prises en considération lors du diagnostic diférentiel. Le but du présent article est de décrire 3 cas différents de tumeurs odontogènes périphériques et de discuter le diagnostic différentiel de l'intumescence gingivale. L'examen histologique est une obligation lors de l'ablation chirugicale d'intumescences gingivales localisées.

A Rare Oral Focal Mucinosis Presentation in the Aesthetic Zone: A Case Report

“…Clinical differential diagnosis of OFM cases reported has varied in the literature and includes fibrous hyperplasia, giant cell fibroma, peripheral giant cell granuloma, peripheral ossifying fibroma, peripheral odontogenic fibroma, squamous papilloma, mucoceole and pyogenic granuloma. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] To the authors knowledge, this is the first case reported where OFM has resembled the appearance of DG.…”

“…Therefore, they are often diagnosed as gingival hyperplasia, fibroma, pyogenic granuloma or fibrous epulis. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Histopathology of OFM shows a focal myxoid degeneration of the connective tissue, possibly due to the over production of hyaluronic acid by fibroblasts during collagen production, and is the definitive diagnosis for OFM. 2 In the current case report, OFM occurred after a routine crown lengthening procedure with clinical presentation resembling that of Desquamative Gingivitis (DG).…”

“…[1][2][3] It presents as a pedunculated or sessile growth with most cases occurring in women. OFM involves the keratinized oral mucosa, with 80% of the lesions developing on the gingiva and the remainder on the palate.…”

Epithelium-poor Odontogenic Fibroma with an Unusual Progress

“…There are some case reports which described simple type COF 4, 6, 10, [15][16][17][18][19][20][21]32) . On the other hand, all of the POF reports that described the histopathological diagnosis were of the WHO type 3, 12,13,23,26,27,30,[33][34][35][36][37][38] , and this is the first report referring to a simple type POF in the English literature. The histopathological findings of OF showed the proliferation of elliptical and spindle-shaped cells, and fibrous connective tissue containing a small amount of odontogenic ectodermal mesenchymal tissue like a mucoid matrix (Fig.…”

“…In this respect, it was considered to be a simple type POF [25][26][27][28][29][30][31] . There are some case reports which described simple type COF 4, 6, 10, [15][16][17][18][19][20][21]32) .…”
