Interesting image. Extrapulmonary small cell carcinoma in prostate: detection with F-18 FDG PET/CT

FDG PET/CT imaging of extrapulmonary small cell carcinoma of the adrenal gland

Extrapulmonary small cell carcinoma (SCC) is an uncommon malignancy. A 57-year-old man was referred because of a 1-month history of left lumbago. MR images showed an ovoid tumor in the left adrenal gland. FDG PET/CT showed intense FDG uptake of the left adrenal tumor with thrombosis of the left renal vein. The patient underwent left adrenalectomy and nephrectomy. Histopathology revealed typical adrenal SCC with neoplastic thrombosis of the left renal vein. This case suggests that FDG PET/CT is useful for staging of extrapulmonary SCC.

Clinical impact of 18F-fluorodeoxyglucose positron emission tomography/computed tomography in the evaluation of small cell carcinoma of the prostate

Small cell carcinoma of prostate (PSCC) is an uncommon and aggressive type of prostate malignancy with limited data on the use of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) in the clinical management of this rare entity. In this report, clinical and imaging findings of a patient with PSCC are presented. We aimed to discuss the role of PET/CT in the evaluation of PSCC in combination with histopathological characteristics of tumor and emphasize the importance of PET/CT in the clinical management of PSCC.
