Lymphoepithelial carcinoma at the lingual apex: a case report
Lymphoepithelial carcinoma (LEC) rarely occurs in the oral cavity, an association with Epstein-Barr virus (EBV) is commonly observed in nasopharyngeal lesions. A biopsy of a lingual apex nodule was sent from an 85-year-old female. Clinically, the lesion was described as oval, sessile, firm, and normochromic. Histopathological analysis showed a malignant neoplasm composed of epidermoid cells isolated or arranged in islands and cords, exhibiting a syncytial appearance. The cells were pleomorphic, with vesiculated nuclei containing acidophilic macronuclei. The stroma was markedly lymphoid with few eosinophils. It penetrated the tumor proliferation, making it difficult to visualize the islands and cords of epidermoid cells. Tumor cells were immunostained for anti-CKPool, anti-EMA, and anti-EBV, suggesting a diagnosis of LEC. The patient was referred to the Head and Neck Service for oncologic treatment. A combination of histopathology and immunohistochemistry is essential for the diagnosis of LEC. Oral lesions may also be associated with EBV.
期刊介绍:
Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology is required reading for anyone in the fields of oral surgery, oral medicine, oral pathology, oral radiology or advanced general practice dentistry. It is the only major dental journal that provides a practical and complete overview of the medical and surgical techniques of dental practice in four areas. Topics covered include such current issues as dental implants, treatment of HIV-infected patients, and evaluation and treatment of TMJ disorders. The official publication for nine societies, the Journal is recommended for initial purchase in the Brandon Hill study, Selected List of Books and Journals for the Small Medical Library.
