Topical Timolol an Option for Treating Pyogenic Granuloma

HUNTINGTON BEACH, Calif. — Mounting evidence suggests that using topical timolol to treat a pyogenic granuloma (PG) may spare children from undergoing a surgical procedure, especially if the PG is small and on the face, according to Julie Dhossche, MD.

A PG is a common, benign vascular tumor that often occurs in children under 5 years of age, “usually in a very inconvenient spot, like the cheek,” Dhossche, a pediatric dermatologist at Oregon Health & Science University (OHSU), Portland, Oregon, said at the annual meeting of the Pacific Dermatologic Association. “It can bleed a lot. Often, parents take their child to the emergency department for unstoppable bleeding. Our first-line treatment is often surgical: Shave removal, electrocautery, or excision.”

Several case reports about the use of the topical form of timolol, a nonselective beta-adrenergic antagonist, for PG have been published in the medical literature including a case series of seven patients (six were treated with topical timolol). The authors of the case series hypothesized that a beta-blocker may be effective for PGs by causing vasoconstriction that stops bleeding.

In addition, Dhossche and colleagues retrospectively evaluated 92 children with a mean age of 4.5 years who were treated with topical timolol for PG at OHSU from 2010 to 2020. The results were presented in an abstract at the 2022 Pediatric Dermatology Research Alliance annual conference.

At the initial visit, 80 of 92 (87%) children were treated with timolol only, 6 of 92 (6.5%) underwent a procedure, and 6 of 92 (6.5%) were treated with timolol and a procedure. The researchers observed that of the 80 patients who received timolol monotherapy, 42 (52.5%) were spared a procedural intervention. “So, we have had some success with this,” she said. “It can also help with bleeding episodes if you are waiting for a procedure.”

Surgery May Still Be Needed

For PGs, she applies one drop of timolol to the lesion under occlusion with DuoDERM or a similar dressing, which is repeated every 1-3 days depending on how long the dressing stays on. “It may take 3-4 months of this treatment to clear,” she said.

If topical timolol doesn’t stop the PG from bleeding, or if parents elect for surgical removal, “some tears [during removal of the lesion] may be inevitable,” Dhossche said. “My goal is to make it as good of an experience as it can be, by being very confident and offering lots of smiles, pretreatment with topical lidocaine for 20-30 minutes, icing, and formulating an alliance with parents” to help calm nerves, “knowing if that doesn’t work, I might need help from my colleagues in pediatric sedation,” she said.

Choice of language matters when describing to children what to expect during a procedure, she continued. For example, instead of saying, “it will feel like a bee sting,” say, “some kids say it is uncomfortable like a pinch and some kids say it’s not so bad.” And, when describing the size of a needle or an incision, instead of saying, “it’s as big as…” say, “it’s as small as…”

As described in a 2020 paper published in Pediatric Dermatology, proper comfort positioning of children during in-office dermatologic procedures is also key, which can include having the parent or caregiver hug a child during removal of a PG, Dhossche said. “You want to optimize distractions for the patient while you do the procedure,” she added. “This is the time to bring out your iPhone, iPad, or enlist help from a certified child life specialist if you have one at your institution.”

When she administers injections to children, “I don’t lie about the shot, but I do hide the actual needle from sight, if possible,” she said. “I’ll say, ‘you’ll feel a pinch’. Vibration tools can help while you’re injecting.” She showed an image of a vibrating light-up children’s toothbrush she found on Amazon for $10 “that has served me well. It’s also kind of a tension diffuser.”

Dhossche reported having no financial disclosures.
