Background: Calcifications or new bone formation can be found in maxillary sinus pathologies such as osteosarcoma, chondrosarcoma as well as calcifying and osteoblastic tumors. Formation of calcifications is also detected in aspergillosis of paranasal sinuses. Case Report: An extremely rare case of planoepithelial carcinoma of the maxillary sinus containing large calcifications is presented. A 54-year old woman was referred to the Department of Maxillofacial Surgery due to the enlargement of the right maxillary tuber. Following the results of diagnostic imaging examinations that disclosed maxillary antrum calcifications in an expansile mass, sarcoma or aggressive aspergillosis were suspected. During surgery numerous stone-like foreign bodies were encountered in the soft tissue masses filling the sinus. The histopathological examination established a surprising diagnosis of planoepithelial carcinoma and confirmed the presence of calcifications. There was no evidence of aspergillosis. Conclusions: Although according to literature maxillofacial and oral carcinoma producing calcifications or presenting bone formation is extremely rare, such possiblitity should be kept in mind.
