Tonsillar focal infectious disease involving IgA nephropathy, pustulosis, and ossification.

We report a rare case of IgA nephropathy (IgAN), that was considered as showing tonsillar focal infection, involving pulmoplantar pustulosis (PPP), and sternocostoclavicular hyperosteosis (SCCH). A 53-year-old man with a 3-year history of PPP had hematuria and proteinuria, and he sometimes had anterior chest pain. He was also diagnosed with IgAN and SCCH. We performed tonsillectomy as a treatment. The tonsillectomy was done with the patient under general anesthesia, and this treatment was followed by steroid therapy. Interestingly, all the symptoms of IgAN, PPP, and SCCH were alleviated 6 months after the tonsillectomy. Thus, tonsillectomy and steroid therapy may be effective and could be considered as treatment for these diseases.
