1Tokyo metropolitan Bokutoh hospital, Division of rheumatic diseases.
Abstract:
The sterile arthro-osteitis, especially in anterior chest wall, and also in spine and peripheral joints were observed in patients with pustulosis palmaris et plamtaris.

Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
