Vulvar keratoacanthoma may be a malignant precursor: A case report and literature review

In terms of histological and clinical presentation, keratoacanthoma may overlap with classical well-differentiated squamous cell carcinoma. In rare cases, certain atypical keratoacanthomas may exhibit intravascular and perineural invasion, along with lymph node metastasis. By sharing our treatment experience of a patient with recurrent vulvar keratoacanthoma following surgery, we aim to provide a cautionary perspective for the clinical management of such cases.
