Concurrent sarcoidal granulomas and melanoma micrometastasis in a sentinel node – a case report

Abstract

Incidental findings of non-caseating granulomas and metastasis in sentinel lymph nodes are rare but cause clinical challenges. We report a case of coinciding unexpected asymptomatic lymphoid sarcoidosis and a micrometastasis in a sentinel node of a patient, who was newly diagnosed with 2.0 mm thick melanoma on the left calf.
