[Coincidence of isolated laryngeal sarcoidosis and laryngeal carcinoma].

Isolated sarcoidosis is quite rare, causing non-specific symptoms and possibly not diagnosed because of the large number of other entities with similar presentations. We report the problems of diagnosis of isolated laryngeal sarcoidosis following a localized carcinoma. A 66-year-old patient was seen in the Westpfalz ENT Department after a Le Roux-Robert fronto-latera laryngeal resection for a pT1a N0 M0 vocal cord carcinoma following progressue dyspnea. Laryngoscopy showed laryngeal stenosis due to a neoplastic lesion. However, an epitheloid granulomatosis was found on histopathology with no evidence for recurrent carcinoma. After exclusion of other processes and systemic disease, the diagnosis of isolated laryngeal sarcoidosis was made and long-term corticoid medication was administered, resulting in a rapid regression of the laryngeal stenosis.
