ABSTRACT
The patient was a 68-year-old man. During follow-up after chemoradiotherapy for prostate cancer, an enlarged intra-abdominal lymph node was noted. He underwent an upper gastrointestinal endoscopy and was suspected of having low-grade B-cell lymphoma, but a definitive diagnosis was not made. Bilateral pulmonary nodules appeared, and the patient was referred to the Department of Respiratory Medicine.
An inguinal lymph node biopsy with accumulation on FDG-PET showed no evidence of malignancy, but an epithelioid granuloma was detected. The patient underwent video-assisted thoracic surgery for a rapidly enlarging pulmonary lesion, leading to a diagnosis of lymphomatoid granulomatosis. Lymphoma may develop during the course of sarcoidosis, and prioritizing lesions considered to be highly active may aid in early diagnosis
