CLINICAL HISTORY: A 6-year-old female presented to our clinic with a four-month history of asymptomatic flesh-colored papules along the intergluteal cleft.

The patient has a past history of intellectual delay, right lower extremity hypertrophy, syndactyly of the 2nd through 4th toes on the right foot, venous malformation involving the right lower thigh, knee, and proximal calf, and lichen striatus of the left lower extremity.

The patient follows closely with a vascular malformation clinic in San Antonio for her diagnosis of Klippel Trenaunay Syndrome. Past surgical history includes syndactyly release of the 4th toe. The patient denies constipation, diarrhea, fevers, chills, trouble sitting or standing, unwanted sexual activity, or use of fragrance wipes. No one in the household has similar lesions.
