Cause
Common cause
Bacterial infection (35%):
The pathogenic bacteria are human papillomavirus (HPV-1, 2, 3, 4, 7, 27, 28, 29), skin and mucosal damage, and abnormal cellular immune function is a direct factor in the infection of this disease.
Environmental factors (25%):
If you don't pay attention to personal hygiene and public health, the things that come into contact with the carriers are not disinfected by hand.
Human papillomavirus enters the exposed basal cells through the wound. The basal cells that can be divided are the storage of viral DNA. The epithelial cells with viral DNA can be in a latent state without any clinical manifestations. Acanthosis hypertrophy, papillary hyperplasia and hyperkeratosis, accompanied by parakeratosis.
Prevention

Examine
Common sputum check
Histopathology can be seen, hyperkeratosis of the epidermis, hypertrophy of the acanthosis, hyperplasia of papilloma, vacuolar cells can be seen in the upper layer and granular layer of the spine cells. The nucleus is small and round, basophilic, surrounded by a narrow halo, epidermis To be prolonged, the epidermis around the ankle is curved toward the center to form a spherical shape, the dermal papilla is extended, and the blood vessels are dilated.
Diagnosis

diagnosis
According to the clinical characteristics, the predilection site and pathological examination, the diagnosis is not difficult.
Differential diagnosis
1. : from childhood, often arranged in a line, consistent with the nerves, smooth or rough surface, thorn-like bulge, pale brown or grayish yellow, no consciousness.
2. Sickle tuberculosis: an irregular plaque, surrounded by dark red infiltration, histopathological specific tuberculous granuloma.
