A vulvar fibroepithelial stromal polyp appearing in infancy.

We present here a first case of vulvar fibroepithelial stromal polyp (vFSP) appearing in infancy, including previously undescribed papule as an early form of vFSP. A 7-month-old girl presented with a small (adzuki-sized), soft, erythematous papule in the right labium majus. The size of the lesion increased up to 2.3 cm in the following 7 months and exhibited cerebriform or frond-like configuration. The surgically removed polyp was characterized by the proliferation of bland spindle cells with tapered cytoplasm, and the diagnosis of vFSP was established. Twenty-one months after the first surgery, a recurrent polyp 2.0 cm in size was resected. No further recurrence has been observed in the 17 months since the second surgery.
