According to the literature, surgery is considered the first-line therapy for such patient. Therefore, we collected and analyzed preoperative and postoperative data to evaluate the surgical outcome and prognosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>A 28-year-old female patient had manifested erosions on oral mucosa and fingers for several months. Contrast-enhanced CT imaging revealed an abdominal mass. Histopathology of the lesions revealed lichenoid interface dermatitis. Direct immunofluorescence examination of the skin revealed a reticular deposition of IgG and C3 in the intercellular spaces of the epidermis. According to the latest diagnostic criteria, she was diagnosed with PNP. She underwent surgery at our hospital, during which the mass was completely resected. Postoperative pathology confirmed the mass as UCD, specifically of the hyaline vascular type. Following the surgery, the patient was concurrently treated with a tapering regimen of oral glucocorticoids. After 2 years of follow-up, there was no recurrence of the oral or hand erosions, and a repeat abdominal CT scan showed no evidence of mass recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Complete resection is the first-line therapy for UCD with PNP.
