Crusted plaques on the face.

Facial neutrophilic dermatosis is a relatively recent and rare entity. Herein, we report an original case with a clinical appearance of crusty pyoderma gangrenosum and limited face involvement, classifying it as neutrophilic dermatosis (ND) of the face. The latter is an infrequent entity and forms part of the ND spectrum. The few reported cases in the literature are characterized by a restricted distribution on the face, as in our case. Nevertheless, this entity remains controversial: some consider it a variant of Sweet's syndrome; others see it as a truly independent entity. Matthews et al. reported an association between ND of the face, as in the case of our patient with a crusty appearance, and ulcerative colitis. Our observation and that of Matthews et al. underline the wide and varied potential for the clinical presentation of this entity. [ABSTRACT FROM AUTHOR]
