Pyogenic granulomas are fleshy, moist or crusty, usually scarlet vascular nodules composed of proliferating capillaries in an edematous stroma.
The lesion, composed of vascular tissue, is neither of bacterial origin nor a true granuloma. It develops rapidly, often at the site of recent injury (although injury may not be recalled by the patient), typically grows no larger than 2 cm in diameter, and probably represents a vascular and fibrous response to injury. The incidence of pyogenic granuloma varies by age, sex, and anatomic location; granulomas on the head, neck and trunk appear to be most common in males aged < 20 years and females aged between 20 and 50 (1).
The overlying epidermis is thin, and the lesion tends to be friable, bleeds easily, and does not blanch on pressure. The base may be pedunculated and surrounded by a collarette of epidermis.
During pregnancy, pyogenic granulomas may form on the gingiva and become large and exuberant (called gingival pregnancy tumors or telangiectatic epulis).

Diagnosis of Pyogenic Granulomas
Biopsy
The Diagnosis of pyogenic granuloma is by biopsy and histologic examination. Histologic analysis is required for all tissue removed because these lesions occasionally resemble and must be differentiated from melanomas or other malignant tumors.
Treatment of Pyogenic Granulomas
Excision or curettage and electrodesiccation
Treatment of pyogenic granulomas consists of removal by excision or curettage and electrodesiccation; lesions may recur.
