Erosive pustular dermatosis of the scalp and leg associated with myasthenia gravis: A possible pathogenetic role for neutrophil-stimulating cytokines and chemokines.

ISSN 0001-5555 Erosive pustular dermatosis (EPD) is a rare condition characterized by pustules, erosions and crusted lesions, which ultimately result in scarring alopecia (1). Cultures are generally negative, and laboratory and histopathological evaluations are not diagnostic. The development of EPD has been observed previously in some specific conditions such as long-standing solar damage (2), and its association with autoimmune diseases has also been described (3). However, the pathogenesis of EPD remains unclear. We report here a case of EPD of the scalp and leg associated with myasthenia gravis.
