Many advances in dermatology have been made in recent years. In the present review article, newly described disorders from the last six years are presented in detail. We divided these reports into different sections, including syndromes, autoinflammatory diseases, tumors, and unclassified disease. Syndromes included are "circumferential skin creases Kunze type" and "unusual type of pachyonychia...

Introduction Pyogenic arthritis, pyoderma gangrenosum, and acne (PAPA) syndrome is an autosomal dominant autoinflammatory disease caused by mutations in the proline-serinethreonine phosphatase-interacting protein 1, PSTPIP1. The produced protein is a cytoskeleton-associated adaptor protein that modulates T-cell activation, cytoskeletal organization and IL-1b release. The only two mutations desc...

IBD: inflammatory bowel disease PG: pyoderma gangrenosum TNF-a: tumor necrosis factor alpha INTRODUCTION Pyoderma gangrenosum (PG) is a rare infiltrative neutrophilic dermatosis that characteristically presents with painful ulcers with violaceous, undermined borders on the lower extremities and less commonly presents with tender nodules or pustules. Along with erythema nodosum, PG is one of the...

Pyoderma gangrenosum is an intractable skin disorder characterized by the development of erythematous pustules or nodules that rapidly progress to destructive, necrotizing, non-infective ulcers. We assessed the efficacy of granulocyte and monocyte adsorption apheresis (GCAP) therapy in two new patients, a 67-year-old man with ulcerations on his lower leg, and a 44-year-old man with turgid eryth...

463 was no malignant transformation at all, nor any local or distant metastasis. This case is the largest in size ever reported in the literature, measuring 21 cm×17 cm×12 cm. Although the radiological findings sug­ gested the involvement of the pericranium, surgical exploration and the management plan favored simple excision with a free margin and skin graft coverage. During extended follow­up...

Pyoderma gangrenosum (PG) is a rare noninfectious neutrophilic dermatosis. Clinically it starts with sterile pustules that rapidly progress and turn into painful ulcers of variable depth and size with undermined violaceous borders. The legs are most commonly affected but other parts of the skin and mucous membranes may also be involved. Course can be mild or malignant, chronic or relapsing with...
