Abstract
Cribriform adenocarcinoma of minor salivary gland (CAMSG) is currently classified as a subtype of polymorphous adenocarcinoma. CAMSG differs from polymorphous adenocarcinoma in that it has a distinct histopathologic appearance and clinically CAMSG has higher rate of lymph node metastasis at initial presentation. Panoramic radiograph shows an ill-defined radiolucent lesion in the right maxilla that extends from the distal of maxillary right canine to the mesial of maxillary second molar. The lesion has invasive borders and causes destruction and loss of the lamina dura and periodontal ligament space in the mesial of the second molar and distal of the canine. The lesion has also invaded into the right maxillary sinus destroying the floor of sinus. CBCT images show a low attenuation lesion involving the right maxillary alveolar bone at the premolars and first molar area. This report describes the radiographic appearance of a case of CAMSG on panoramic radiograph, cone-beam computed tomography (CBCT), multi-detector computed tomography (MDCT) and on magnetic resonance imaging (MRI).
