Pestle finger is mainly manifested as a thick finger or toe with thickened and thickened nails or toenails, with much bulging in the center, resulting in a bulging change in the end joints.
Pestle finger is only a clinical symptom, multi-system lesions can lead to the appearance of pestle finger, such as: respiratory system lesions (chronic lung abscess, pyothorax, emphysema, bronchopulmonary carcinoma, bronchiectasis, etc.), digestive system lesions (Crohn’s disease, chronic ulcerative colitis, intestinal tuberculosis, multiple polyps in the colon, etc.), circulatory system lesions (tetralogy of Fallot, subacute bacterial endocarditis, infective myocarditis, rheumatic heart disease, etc.), etc.
As a result, patients present with symptoms of primary systemic pathology in addition to changes in the fingers and toes.
