甲状腺悪性リンパ腫に対して輪状軟骨開窓術を施行した 1 例

The most common clinical feature of a primary thyroid lymphoma is a rapidly growing thyroid mass, mimicking anaplastic carcinoma, often with dyspnea. A 77-year-old man presented with a rapidly growing neck mass and dyspnea. Computed tomography (CT) showed diffuse enlargement of the thyroid, with compression of the trachea. As the patient showed evidence of airway obstruction, taking into account the tumor location of the tumor, we performed cricotracheostomy, and obtained a biopsy specimen from the thyroid for histopathological examination. The lesion was diagnosed as a thyroid lymphoma, and the patient was treated with six courses of R-THP-COP chemotherapy. Following this treatment, he achieved complete remission. We present a case of cricotracheostomy performed for a patient with a primary thyroid lymphoma. Despite the tumor surrounding the trachea, by selecting cricotracheostomy, we could create an opening in the airway more easily and safely, and even obtained a biopsy specimen.
