Table 1 – Literature review of the reported cases of Adenoid Cystic Carcinoma of the buccal mucosa (2010 – present)
Figure legends:
Figure 1- CT-scan view of the lesion demonstrates ill-defined mass of right buccal area with invasion to the surrounding structures of the skin and zygomatic bone.
Figure 2- Histopathologic views of the lesion. a) small basaloid tumoral cells in various sized nests (H&E staining, ×100 magnification). b) classic cribriform pattern in tumoral cells (H&E staining, ×100 magnification). c) immunohistochemistry results show severe diffuse positive immunoreaction for C-kit (×100 magnification). d) ki67 was positive in about 10% of tumoral cells.
Figure 3- Surgical intervention. a) whole excited lesion with safe margin. b) excited zygomatic bone and maxillary tuberosity. c) pedicled right temporalis muscle flap was used for reconstruction of the surgical area. d) transferred flap to the surgical area.
Figure 4- Follow up of the patient after one and half year shows ideal healing without significant problem.
Figure 5- a) microscopic examinations shows tubular pattern of small basaloid tumoral cells (H&E staining, ×100 magnification). b) tumoral cells demonstrate admixture of cribriform and tubular pattern (H&E staining, ×100 magnification). c) diffuse positive C-kit immunoreaction in tumoral cells (IHC, ×400 magnification). d) positive immunoreaction for ki67 in about 10% of tumoral cells (IHC, ×400 magnification).
