Examine
Examination of sputum-like pyoderma
Histopathology: The entire epidermal layer presents an inflammatory response, which is filled with lymphocytes, plasma cells, fibroblasts and mast cells, and may also be negative for special staining of eosinophils, fungi and bacilli.
In addition to the cultivation of Staphylococcus aureus, other fungi or virus cultures were negative, no Treponema pallidum was found, and syphilis serum reaction was negative.
Diagnosis

Diagnosis is based on clinical presentation and access.
