A 73-year-old woman with a mass in the right parotid region was referred to our hospital. Radiological imaging tests revealed a well-defined mass, measuring 25 mm in diameter, with foci of calcification in the deep lobe of the parotid gland, extending to the parapharyngeal space. Microscopically, the tumor was composed of a proliferation of atypical glandular epithelial cells having intracytoplasmic mucin, squamoid cells, and intermediate cells arranged in nests embedded in a fibrosclerotic stroma, associated with a dense chronic inflammatory infiltrate containing immunoglobulin G4-immunoreactive plasma cells. Reverse transcription-polymerase chain reaction analysis using a formalin-fixed, paraffin-embedded tumor tissue specimen revealed the CRTC1-MAML2 fusion gene transcript. This is the first report of sclerosing MEC with the detection of the MEC-associated fusion gene, reinforcing a common genetic association between MEC and sclerosing MEC.<\/jats:p>","DOI":"10.1177\/1066896917742721","type":"journal-article","created":{"date-parts":[[2017,11,24]],"date-time":"2017-11-24T01:49:30Z","timestamp":1511488170000},"page":"250-255","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":15,"title":["Sclerosing Mucoepidermoid Carcinoma in the Parotid Gland With\n                    <i>CRTC1-MAML2<\/i>\n                    Fusion: A Case Report"],"prefix":"10.1177","volume":"26","author":[{"given":"Kei","family":"Yabuki","sequence":"first","affiliation":[{"name":"University of Occupational and Environmental Health, Kitakyushu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atsuji","family":"Matsuyama","sequence":"additional","affiliation":[{"name":"University of Occupational and Environmental Health, Kitakyushu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eisuke","family":"Shiba","sequence":"additional","affiliation":[{"name":"University of Occupational and Environmental Health, Kitakyushu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gunji","family":"Nagatani","sequence":"additional","affiliation":[{"name":"University of Occupational and Environmental Health, Kitakyushu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masanori","family":"Hisaoka","sequence":"additional","affiliation":[{"name":"University of Occupational and Environmental Health, Kitakyushu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,11,23]]},"reference":[{"key":"bibr1-1066896917742721","doi-asserted-by":"crossref","first-page":"173","DOI":"10.55418\/9781933477442-5","volume-title":"AFIP Atlas of Tumor Pathology.
