Tekstualni opis
Clinically, onset occurs with sterile pustules that rapidly progress and turn into very painful ulcers of variable depth and size, with undermined bluish or violaceous borders and surrounding erythema. The legs are most commonly affected but other parts of the skin and mucous membranes may also be involved. The clinical course can be mild or malignant, chronic or relapsing with significant morbidity. In many cases, PG is associated with an underlying disease, most commonly inflammatory bowel disease, rheumatic or hematological disease, or malignancy.
Etiologija
The etiology has not yet been clearly determined.

The treatment of PG is a challenge. Randomized, double-blind prospective multicenter trials for PG are not available. The best documented treatments are systemic corticosteroids and cyclosporin A. Combinations of steroids with cytotoxic drugs are used in resistant cases. The combinations of steroids with sulfa drugs or immunosuppressants are used as steroid sparing modalities. Rapid improvement of PG has been obtained by anti-tumor necrosis alpha therapy used in Crohn's disease. Skin transplants and the application of bioengineered skin is useful in selected cases, as a complementary therapy to the immunosuppressive treatment. Topical therapy with modern wound dressings is useful to minimize pain and the risk of secondary infections.
Dijagnostičke metode
Diagnosis of PG is based on the history of the underlying disease, typical clinical presentation, histopathology, and exclusion of other diseases that would lead to a similar clinical picture.
