Abstract: A 55-year-old man with no relevant history was analyzed for weight loss, night sweats, and left upper quadrant pain. An abdominal ultrasound and CT scan were performed, revealing a lobulated rim-enhancing mass in the left adrenal gland. Further analysis by an 18F-FDG PET/CT scan demonstrated high uptake in the periphery of the adrenal lesion with central photopenia. Because a primary malignancy was suspected, an adrenalectomy was performed. Histopathology, however, revealed a necrotizing granulomatous infection. Serum was tested positive for syphilis and Treponema pallidum infection. Results of additional HIV tests were negative. The adrenal tumor proved to be an expression of gummatous syphilis.
