초록
Inflammatory pseudotumor represent a heterogenous group of unusual pseudoneoplastic lesions and chronic inflammatory disease. It is hard to be distinguished from malignant disease by clinical symptoms and radiologic findings. Although there have been some articles reporting the tumor arising in the orbit or nasal cavity, laryngeal pseudotumors are uncommon lesions. 48 year-old male patient was referred from other hospital due to laryngeal abnormality. He complained of voice change since 3 months ago. Laryngoscope and CT findings showed well-demarcated and heterogenous submucosal tumor occupying left paraglottic space. It was removed with CO2 laser via endoscopic approach. Pseudotumor was confirmed on histology and immunohistochemical staining. There has been no evidence of recurrence for 2 years. Accompanied with literature review, we reported a case of laryngeal pseudotumor treated with single surgical therapy.
Abstract
Inflammatory pseudotumor represent a heterogenous group of unusual pseudoneoplastic lesions and chronic inflammatory disease. It is hard to be distinguished from malignant disease by clinical symptoms and radiologic findings. Although there have been some articles reporting the tumor arising in the orbit or nasal cavity, laryngeal pseudotumors are uncommon lesions. 48 year-old male patient was referred from other hospital due to laryngeal abnormality. He complained of voice change since 3 months ago. Laryngoscope and CT findings showed well-demarcated and heterogenous submucosal tumor occupying left paraglottic space. It was removed with CO2 laser via endoscopic approach. Pseudotumor was confirmed on histology and immunohistochemical staining. There has been no evidence of recurrence for 2 years. Accompanied with literature review, we reported a case of laryngeal pseudotumor treated with single surgical therapy.
