Sarcoidosis in head and neck area - a diagnostic challenge using the example of skin manifestations

Abstract

Sarcoidosis is a granulomatous multisystem disease of unknown etiology and relatively rare. The heterogeneous clinical picture is a diagnostic challenge. We are investigating whether the superficially visible cutaneous lesions can lead to the differential diagnosis of sarcoidosis and what systemic manifestations are present. As part of our exploratory retrospective investigation (eight years) a total of 32 patients with cutaneous sarcoidosis were identified and analyzed. In many cases the dermatologists considered the differential diagnosis of sarcoidosis even before biopsy (71.8%); in our previous study with ENT-patients the diagnosis wasn't considered in a single case by the attending doctors at this time and without any prevoius suspicion. Sarcoidosis of the skin in the head and neck area is the second most common cutaneous manifestation. After biopsy (Gold standard) the search for further possible organ manifestations is essential (e.g. lungs, heart) to treat them in an early stage and to prevent complications of a possible chronic course (including cardiac arrhythmias, pulmonary fibrosis).
