title: A case of immunoblastic lymphadenopathy (IBL)-like T-cell lymphoma with unusual clinical manifestations.
abstract: A 67-year-old male consulted an otolaryngologist with a complaint of dysphagia due to a large polypoid mass in the hypopharynx. A biopsy of the mass revealed immunoblastic lymphadenopathy (IBL)-like T-cell lymphoma of helper/inducer subset occurring in lymphoid tissues of the hypopharynx. Although general lymphadenopathy was not seen, further biopsy of an inguinal lymph node showed small foci of lymphoma cells, suggesting the generalized distribution of this malignancy. To our knowledge, this is the first report of this malignancy mimicking primary pharyngeal sarcoma.
