case_images: Clinical examination was significant for multiple, well-demarcated hyperpigmented patches with irregular borders that had a "splashed on" appearance (Figure 1(a) and (b)) and some areas of hypertrichosis (Figure 2(a) and (b)) on the trunk and bilateral lower extremities, extending below the knee.
