[Sarcoidosis in and around the nose: a diagnostic and therapeutic guideline].

In addition to its mucosal pathology, sarcoidosis of the nose may cause a range of skin abnormalities and destruction of the osteocartilaginous structures of the nose. Clinical presentation can mimic other diseases and a biopsy is often necessary. We propose a classification of nasal sarcoidosis based on disease location to help with recognition of the symptoms and, subsequently, treatment. Here we describe 4 patients with nasal sarcoidosis. In the first patient, a 53-year-old woman with a granuloma in the nasal vestibule, the lesion was excised. The second patient, a 38-year-old man with intranasal crusts, synechiae and atrophic mucosa, was treated with corticosteroid nasal drops. The third and fourth patients, a 36-year-old man with progressive widening of the nasal dorsum and a 60-year-old woman with a saddle nose, respectively, were treated with a rhinoplasty.
