Atypical Lipomatous Tumor Originating From the Nasopharynx in a Patient with Chronic Lymphocytic Leukemia.

Atypical lipomatous tumor, also known as well-differentiated liposarcoma, is rare in the head and neck region. The primary and most effective option in the treatment of this malignancy with a good prognosis is excision with clean surgical margins. Therefore, it is important to distinguish this malignancy from lesions that require more aggressive treatment. In this article, we present the case of an atypical lipomatous tumor originating from the nasopharynx and almost completely obstructing the oropharynx in a 38-year-old male patient with chronic lymphocytic leukemia. To the best of our knowledge, this is the first report in the literature of an atypical lipomatous tumor case originating from the nasopharynx.
