Cutaneous Manifestation of Sarcoidosis in Lower-Back Tattoo With Increased Uptake of 18F-FDG

Clin Nucl Med. 2018 Jun;43(6):454-455. doi: 10.1097/RLU.0000000000002061.

Abstract

Sarcoidosis, a granulomatous T-cell-mediated multisystem disease with a yearly incidence of 10.9 to 35.5 cases per 100,000 in the United States, affects a variety of organ systems. Although the characteristic radiological finding of a bihilar lymphadenopathy still plays a diagnostic key role, FDG PET/CT is more sensitive in detecting and monitoring various manifestations. We present a rare case of a 37-year-old woman with bihilar, mediastinal, and abdominal lymphadenopathy in conjunction with a histologically proven cutaneous manifestation of sarcoidosis in a tattoo of the lower back exhibiting an increased uptake of FDG.
