“…Conversely, a low proliferative index of this tumor has been reported in the literature. [2][3][4]14,19,26,30 Considering the variable immunohistochemical profile of the ECT, the high proliferative index suggests the need for constant monitoring of these cases, with special attention to areas containing populations of small cells.…”

An ectomesenchymal chondromyxoid tumor (ECT) is a rare intraoral tumor that should be included in the differential diagnosis of other mesenchymal tumors, particularly when located in the tongue. This study reports a new case of a 34-year-old female patient with a nodular lesion on the tongue dorsum. Its clinical diagnosis was irritative fibroma. The lesion was surgically removed, and, after 2 years of follow-up, no recurrence was observed. A detailed description of the histomorphological and immunohistochemical features of the ECT was made, highlighting the high Ki-67 proliferative index observed. (Rev Port Es

“…A pontos diagnózis a klinikai jellegzetességek, a fénymikroszkópos kép és az immunhisztokémiai vizsgálatok alapján állítható fel [10]. A nemzetközi szakirodalomban eddig mindösszesen 93 esetet publikáltak [3,8,[11][12][13][14]; jelen közleményünkben -ismereteink szerint hazánkban elsőként -egy újabb esetről számolunk be.…”

Ectomesenchymal chondromyxoid tumor is a rare benign intraoral soft tissue neoplasm. Till date, 93 cases have been reported in literature. Clinically, it presents as a slowly growing, painless, ﬁrm, submucosal swelling mainly occurring on the anterior two thirds of the dorsum of the tongue. Histopathologically, the tumor is characterized by a well circumscribed, lobular proliferation of round, polygonal, or fusiform cells in a net-like pattern in a myxoid to chondromyxoid background. Although it shows a morphological resemblance to myoepitheliomas of soft tissue and skin, the exact histogenesis remains unclear; a recent publication of a large series has demonstrated recurrent RREB1-MKL2 gene fusions in 90% of the cases, suggesting the possibility of a new entity. The diagnosis is largely supported by immunhistochemical investigations. Here, we present a new case of ECT occurring in a 62-year-old male who presented with a leading complaint of slowly growing painless mass arising from the anterior part of the tongue measuring about 3 cm. This lesion was diagnosed 4 years before recent admittance, but the patient did not undergo the scheduled surgical intervention and was lost to follow-up. As the tumor was still persisting and moderately enlarging, he came back to our clinic. Finally, the mass was completely resected; after 24 month of follow-up, he is doing well, with no signs of recurrence. Orv Hetil. 2019; 160(33): 1319–1323.
