The FP suspected that the child had morphea because the skin was somewhat firm and thickened, and there was hypo- and hyperpigmentation.
Morphea is a localized type of scleroderma and may be seen in children. Fortunately, it does not involve the internal organs. There are no blood tests needed for the diagnosis and antinuclear antibodies should be normal. While a punch biopsy could be considered in less obvious cases in older children, it is probably unnecessary to put a 5-year-old child through the trauma of a biopsy.
The FP referred the child to a dermatologist to confirm the diagnosis and initiate treatment. Typical treatments include topical mid- to high-potency steroids and/or topical calcineurin inhibitors.
