Lupus pernio. Radiogallium imaging in a patient with chronic cutaneous sarcoidosis

A 37-year-old man with a history of chronic skin sarcoidosis had the classic triad of lupus pernio. Each of the lesions (nose, ears, and hands) revealed avid radiogallium accumulation. In addition, both the panda sign and the lambda sign of hilar-mediastinal lymph node uptake of radiogallium were present, despite normal results of chest radiography. Several other lymph node chains were also involved. The case can serve as a baseline to determine if other instances of lupus pernio have such a wide systemic distribution of radiogallium uptake.
