Pyogenic granuloma is a relatively common skin growth that appears as a shiny red mass. It is sometimes called ‘granuloma telangiectaticum’, or lobular capillary angioma. The surface has a raspberry-like or raw minced meat color in appearance. Although they are benign (non-cancerous), pyogenic granulomas can cause problems of discomfort and profuse bleeding.

Pyogenic Granuloma
What is Pyogenic Granuloma?
*Disclaimer: Individual results may vary from patient to patient based upon the circumstances and the patient’s specific situation, as well as the time taken to see final results.
What Causes Pyogenic Granuloma?
The cause of pyogenic granuloma is unknown. The following factors have been identified as having a possible role to play in their development:
- Trauma: some cases develop at the site of a recent minor injury, such as a pinprick.
- Infection: Staphylococcus aureus is frequently present in the lesion
- Hormonal influences: they occur in up to 5% of pregnancies and are rarely associated with oral contraceptives.
- Drug-induced: multiple lesions sometimes develop in patients on systemic retinoids (acitretin or isotretinoin) or protease inhibitors
- Viral infection is possible but not proven
- Underlying microscopic blood vessel malformations
What Are the Signs & Symptoms?
Lesions usually first appear as a small pinhead-sized red, brownish-red or blue-black spot that grows rapidly over a period of a few days to weeks to anywhere between 2mm and 2cm in diameter. Occasionally they may reach up to 5cm. They bleed easily and may ulcerate and form crusted sores. Usually a single lesion is present but in rare cases groups of multiple lesions may develop.
Lesions most frequently appear on the head, neck, upper trunk and hands (especially fingers) and feet. The pregnancy variant of pyogenic granuloma most often occurs on the mucosal surfaces inside the mouth.
The condition is usually painless with most patients mainly complaining of recurrent bleeding from the lesion.
Who gets pyogenic granuloma?
Pyogenic Granuloma affects people of all races. In general, women are affected more often than men because of the link with pregnancy. It rarely occurs in children less than 6 months old but is common in children and young adults.
How is Pyogenic Granuloma Diagnosed?
Pyogenic Granuloma is usually diagnosed clinically because of typical time course and appearance and they are usually removed surgically. Histology is essential to confirm the diagnosis, and to rule out a form of skin cancer such as amelanotic (non-pigmented) melanoma. A lobular collection of blood vessels within inflamed tissue is typical of Pyogenic Granuloma
What Treatment is Available for Pyogenic Granuloma?
Pyogenic granulomas in pregnant women may go away on their own after delivery so waiting is the best strategy in these cases. If due to a drug, they usually disappear when the drug is stopped.
Pyogenic granulomas in other cases tend to persist. There are several methods used to remove them.
- Curettage and cauterisation: the lesion is scraped off with a curette and the feeding blood vessel cauterised to reduce the chances of re-growth
- Pulse dye Laser: we can use our laser to remove the lesion and burn the base, or to shrink small lesions – READ MORE
- Cryotherapy may be suitable for small lesions – READ MORE
- Chemical cauterisation using silver nitrate is convenient
- Imiquimod has been reported to be effective and may be particularly useful in children
Recurrence after treatment is common because feeding blood vessels extend deep into the dermis in a cone-like manner. In these cases, the most effective method of removal is to cut out completely the affected area (excision), and then close with stitches by the hands or our expert dermatologists.
