Small cell lung cancer with thyroid gland oligometastasis: A case report

This study reports the case of a 72‐year‐old Japanese male. A mass lesion was identified on chest computed tomography (CT). Fluorodeoxyglucose‐positron emission tomography/computed tomography (FDG‐PET/CT) revealed a solitary thyroid gland lesion with high FDG uptake as an extrapulmonary finding, suggesting thyroid cancer or a goiter. Upon confirmation of diagnosis, treatment of SCLC was prioritized, and chemoradiotherapy for limited disease SCLC was init iated without further examination of the thyroid gland. The thyroid nodule disappeared after treatment. Two years later, the disease recurred, and a thyroid nodule was found to have reappeared. Upon fine needle aspiration cytology of the thyroid, small cell carcinoma was detected. Therefore, in case s of SCLC, it is necessary to carefully investigate the thyroid for solitary lesions to consider the possibility of oligometastasis.Key pointsSignificant findings of the studyManifesting as a solitary lesion, oligometastasis, particularly in the thyroid, is rare in cases of ED ‐SCLC.What this study addsIn SCLC cases, it is necessary to carefully investigate the thyroid for solitary lesions to consider the possibility of oligometastasis.
