Erythrokeratodermia variabilis: Two case reports
A 10-year-old boy came to our clinic for brownish and red spots that had started 5 years ago and had appeared from time to time. The red spots initially spread centrifugally and disappeared without any mark, however, the brownish lesions on the anterior part of trunk and arms did not disappear. He was seen by different physicians and was treated with various fungal treatments that were not beneficial. No similar lesions were detected in other family members. No systemic disease was detected.\nThe dermatological examination showed erythematous, annular plaques located on the anterior part of chest, arms, and neck; and brownish hyperkeratotic plaques on the left shoulder and axillary region [Figure and ]. No lesions were detected on the palm, sole, nail, hair, teeth, or mucosa. The histopathological examination of the hyperkeratotic plaque showed hyperkeratosis with moderate papillomatosis and acanthosis [].
