Objective: To report the clinical evolution and handling of a Spitz nevus, from its initial
flat feature to becoming an irregular, nodular, reddish lesion.Case description: Female child, phototype II, with a small congenital nevus on the left lower limb
and other sustained small nevi. The patient went through annual clinical and
dermoscopic evaluations between the ages of three and seven, period during which
the nevi located on the left thigh grew rapidly. The clinical hypothesis was Spitz
nevus, with indication of surgical removal with a safety margin and
anatomopathological study. Considering patient’s age and clinical/histological
aspects, the diagnosis of Spitz nevus was confirmed. Comments: Initial globular pattern and size under 5 mm upon dermoscopy allowed clinical
follow-up. However, onset of hyperchromia and rapid growing of the lesion, along
with aesthetic concerns, possibility of trauma in the region, and risk of
malignancy at puberty guided the decision of total resection and follow-up for
recurrence.
