fa Heterotopic gastrointestinal mucosa in the oral cavity of adults پاتولوزی دهان، فک و صورت Oral and Maxillofacial Pathology پژوهشي Research Heterotopic gastrointestinal mucosa (HGM) is a rare entity observed in the head and neck region and occurs more frequently in male infants and children. The floor of the mouth and anterior aspects of the tongue are the most commonly affected sites. Histologically, HGM resembles gastric, intestinal or colonic mucosa with areas of squamous epithelium, which can be cystic or solid. In the current report, 2 cases of HGM affecting the oral mucosa in patients over 35 years of age are presented, and one of these cases presented 2 nodules in different locations. Both cases represented solid lesions instead of the more common cystic presentation showing gastric glandular-type tissue that was lined with pseudostratified columnar epithelium containing crypts and fundic glands. Immunohistochemical analysis revealed positive expression of cytokeratins 7, 8 and 18 and smooth muscle actin (SMA). In both cases, the final diagnosis was HGM, and conservative surgical excision was performed. <hr><p> <strong>Source: </strong>Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology </p><p> <a href="http://www.oooojournal.net/article/S2212-4403(12)01762-2/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1640&slc_lang=fa&sid=1 Fabiana Martins 10031947532846007659 10031947532846007659 Yes Department of Oral Pathology and Oral Diagnosis, School of Dentistry, University of São Paulo, São Paulo, Brazil Karen Renata Hiraki 10031947532846007660 10031947532846007660 No Department of Microbiology, University of Uberlândia, Minas Gerais, Brazil Maria Ângela Mimura 10031947532846007661 10031947532846007661 No Department of Oral Pathology and Oral Diagnosis, School of Dentistry, University of São Paulo, São Paulo, Brazil Basílio de Almeida Milani 10031947532846007662 10031947532846007662 No Department of Oral Surgery, School of Dentistry, University of São Paulo, São Paulo, Brazil Marina Gallottini 10031947532846007663 10031947532846007663 No Department of Oral Pathology and Oral Diagnosis, School of Dentistry, University of São Paulo, São Paulo, Brazil Marília Trierveiler Martins 10031947532846007664 10031947532846007664 No Department of Oral Pathology and Oral Diagnosis, School of Dentistry, University of São Paulo, São Paulo, Brazil Suzana Orsini Machado de Sousa 10031947532846007665 10031947532846007665 No Department of Oral Pathology and Oral Diagnosis, School of Dentistry, University of São Paulo, São Paulo, Brazil
