Pyogenic granuloma

Pyogenic granuloma is a common benign skin growth that appears as a small, red, and often rapidly growing bump. It usually affects the skin or mucous membranes, such as inside the mouth or on the fingers. This condition involves an overgrowth of tiny blood vessels, making the lesion prone to bleeding easily even with minor injury. It is not caused by infection despite the name and is not cancerous. The growth can be uncomfortable or unsightly but generally does not cause serious health problems. It often develops after minor trauma or irritation to the skin. Treatment typically involves removal to prevent recurrent bleeding.

Pyogenic granuloma is a benign vascular lesion characterized by a lobular proliferation of capillaries within a fibromyxoid stroma. It commonly arises due to reactive hyperplasia following minor trauma or irritation, leading to excessive angiogenesis. Despite the name, it is neither pyogenic nor a true granuloma. The lesion presents as a rapidly growing, friable, red papule or nodule that bleeds easily due to its high vascularity. It most frequently occurs on the skin or mucous membranes, especially the gingiva, fingers, and face. Histologically, it shows a lobular arrangement of capillaries with an inflammatory infiltrate. The major clinical significance lies in its tendency to bleed and its potential to be mistaken for malignant tumors.
