Inflammatory Nasal Polyp With Benign Lymphangioendothelioma/Acquired Progressive Lymphangioma in a Young Man

Year: 2024

Type: article

Abstract: A 17-year-old Japanese male presented with a nasal polyp and neck lymphadenopathy. He was referred to our hospital for diagnosis and treatment of neck lymphadenopathy. Grossly, a whitish pedunculated nasal polyp was observed on the right side of the nasal septum. Computed tomography confirmed the presence of a nasal polyp and two nodular lesions in the right maxillary sinus. All three lesions showed no contrast enhancement. Clinical examination revealed neck lymphadenopathy, suggestive of Kikuchi disease. The nasal polyp was resected, and pathological examination revealed an inflammatory nasal polyp with benign lymphangioendothelioma, also known as acquired progressive lymphangioma. The right maxillary sinus nodules were followed up. The nasal occurrence of benign lymphangioendothelioma is markedly unusual, as the lesion typically occurs in the skin. To the best of our knowledge, this is the first reported case of nasal benign lymphangioendothelioma in our review of the PubMed database.
