Abstract
INTRODUCTION: Subungual pyogenic granuloma (PG) can be caused by numerous medications including chemotherapeutic agents. These lesions grow rapidly, oftentimes causing significant pain and bleeding, prompting patients to seek treatment. The management of subungual PG ranges from topical steroids to surgical excision. However, patients with chemotherapy-induced PGs are prone to developing multiple or recurrent lesions. Therefore, finding a therapeutic option that effectively eliminates the tumor and prevents the need for repeated procedural interventions is important. The use of topical β-adrenergic antagonists has been reported to be effective in regressing cutaneous PG. CASE PRESENTATION: In this report, we present a case of chemotherapy-induced subungual PG of the toenail arising in a 62-year-old woman that was successfully treated with topical timolol solution. CONCLUSION: This case highlights the promising use of timolol solution for therapeutically challenging PGs, such as those of subungual regions. This option may be particularly useful for individuals who are vulnerable to multiple PGs secondary to chemotherapy who wish to avoid repeated procedural interventions.
