| Although direct infections of the spinal cord are rare, pyogenic or tuberculous epidural spinal abscesses are treatable diseases. |
| As the lesions enlarge, they may resemble a cellulitis, pyogenic furuncle, or an infected sebaceous cyst. |
| Electrosurgical treatment is ideal for pyogenic granulomas, which are very vascular, benign tumors. |
| Group A streptococci are the most important human pathogens causing acute pyogenic infections such as pharyngitis and pyoderma. |
| Therefore, nodular amelanotic melanoma is the most important tumor to differentiate from pyogenic granuloma. |
| Brain abscesses may develop when pyogenic organisms are introduced into the neuroparenchyma. |
