Adenomatoid odontogenic tumor: A unique report with histological diversity.

Mutalik VS, Shreshtha A, Mutalik SS, Radhakrishnan R - J Oral Maxillofac Pathol (2012)

Bottom Line: Adenomatoid odontogenic tumor (AOT) is a relatively rare and distinct odontogenic tumor that is exclusively odontogenic epithelium in origin.Although considerable number of reports is available with regard to the clinical and histological spectrum of AOT, very few have highlighted its varied histological presentations.Therefore, this article focuses on the assorted histoarchitectural patterns of AOT.

ABSTRACT
Odontogenic tumors are a group of heterogeneous lesions, features of which have been catalogued for several decades. Adenomatoid odontogenic tumor (AOT) is a relatively rare and distinct odontogenic tumor that is exclusively odontogenic epithelium in origin. Although considerable number of reports is available with regard to the clinical and histological spectrum of AOT, very few have highlighted its varied histological presentations. Therefore, this article focuses on the assorted histoarchitectural patterns of AOT.

(a) Cellular multinodular proliferation of cells in the form of nests and rosettes. (H and E, ×4). (b) Solid areas of cells in the form of whorls interspersed with areas of calcification. (H and E, ×10). (c) Duct-like pattern lined by cuboidal cells (H and E, ×20), inset showing the characteristic rosette like structure (H and E, ×40).

Figure 2: (a) Cellular multinodular proliferation of cells in the form of nests and rosettes. (H and E, ×4). (b) Solid areas of cells in the form of whorls interspersed with areas of calcification. (H and E, ×10). (c) Duct-like pattern lined by cuboidal cells (H and E, ×20), inset showing the characteristic rosette like structure (H and E, ×40). (d) Curved rows of cells giving a tubular appearance (H and E, ×10)

Mentions: Histopathology revealed cuboidal to columnar cells arranged in the form of nests and rosettes. Solid areas, duct-like pattern, whorled arrangement of cells, and tubular appearance is evident [Figure 2]. Convoluted structures were noted and at the periphery of the lesion tumor cells are arranged in a strand-like configuration. Few cells were also arranged in a plexiform pattern and cribriform areas are also seen [Figure 3]. Latticework pattern is seen closer to the connective tissue capsule and foci of dense extravasated red blood cells were seen in few areas. Some amount of calcification, eosinophilic material, and leisegang ring formation was also observed [Figure 4].
