Superficial Radiotherapy (SRT-100) as an Effective Noninvasive Treatment for Pyogenic Granuloma: Case Report and Literature Review

Abstract

Introduction. Pyogenic granuloma (PG) is a common condition characterized by the appearance of a small raspberry-like vascular growth that may appear on any part of the skin. PG usually occurs secondary to acute or chronic trauma. The primary treatment for PG is noninvasive therapy. In refractory cases, surgical resection is an alternative. Superficial radiation therapy system (SRT-100) is a new technology that uses low-energy radiotherapy to treat nonmelanoma skin cancers. SRT may also be used for the treatment of patients with PG who are unwilling to undergo surgery. Case Presentation. A 27-year-old woman presented with a recurrent neoplasm in the middle finger of the left hand after surgical resection. She refused to undergo reoperation or other aggressive options such as electrocautery or liquid nitrogen cryotherapy, so we prescribed only superficial radiotherapy (SRT-100) alone, with a total dose of 14 Gy in four fractions. Conclusion. The neoplasm gradually flattened after treatment with 14 Gy in four fractions and disappeared completely 3 months after completion of treatment.
