CIN3に対するロボット支援腹腔鏡下子宮全摘出術後に子宮頸癌IB１期の診断および多発リンパ節転移が疑われ、最終的にサルコイドーシスと診断した一例

　Sarcoidosis is a systemic disease that forms non-desmoplastic epithelioid cell granulomas, with lesions in the lungs, heart, eyes, skin, lymph nodes, and other organs, presenting with a variety of symptoms, and it has been suggested to be associated with malignancy.

　We present a case of a 71-year-old woman (gravida 2, para 2), in whom a robot-assisted laparoscopic total hysterectomy was performed for CIN3. The postoperative diagnosis was stage IB1 cervical cancer, and postoperative PET/CT scan showed multiple FDG accumulations in lymph nodes. Since metastasis of cervical cancer or malignant lymphoma were considered as differential diagnoses, bronchoscopic lymph node biopsy was performed, and the final diagnosis of sarcoidosis was made.

　When lymph node enlargement is observed, it is important to consider not only cancer metastasis but also sarcoidosis and to perform a pathological search.
