RESUMEN
The first case reported in the literature of a rare disease called necrotizing scialometaplasia (NS), dates back to 1973 when Abrams et al. described the main histological features of this disease. In this article we describe the rare clinical case of a young woman came to our observation for a double ulcer in the middle portion of the hard palate, aching, that histological examination showed compatible with a diagnosis of NS and preceded his appearance a haemorrhagic conjunctival suffusion left. We have provided a complete description of all the investigations in which the patient underwent and its treatment. We have also outlined the major etiological hypotheses of SN, histological features that point to a correct diagnosis, clinical features and prognostic and finally we reflected on the rare and interesting overlap in clinical manifestations palatal and conjunctival those trying to find a possible explanation.
