Rosai-Dorfman disease (RDD), or sinus histiocytosis with massive lymphadenopathy, commonly involves the lymph nodes but may secondarily involve the skin. Purely cutaneous disease without lymphatics or internal organ involvement occurs rarely. The present report detailed a rare case of 18F-fluoro-2-deoxyglucose positron emission-computed tomography (18FDG PET-CT) performed in a 33-year-old male soldier with a purely cutaneous form of RDD. Staging with 18FDG PET-CT was ordered prior to excisional biopsies of the aforedescribed masses and pathology reported RDD. The case demonstrated accurate localization of increased radioglucose metabolism. The present case was also discussed in light of literature data in terms of clinical features, etiologies, histology, medical imaging, therapy planning and prognosis.
