[A cause of palatal necrosis not to ignore]. / Une cause de nécrose palatine à ne pas méconnaître.

We report a case of pseudotumoral nasal septum and hard palate perforation in a 42-years-old man. The diagnosis retained after differential diagnosis exclusion was necrotic midfacial lesion due to chronic inhalation of cocaine. This condition can mimic vasculitis, primary tumors and granulomatous infections. Differential diagnosis and pathophysiology of this condition will be discussed in this anatomo-clinical case.
