case_images: multiple well-circumscribed erythematous nodular hyperkeratosis on scalp (A, B) scar post excision appear closed and the other lesion showed thinning with minimal hyperpigmentation plaque. Four months post-treatment, further significant improvement of the lesions was evident, leaving only minimal hyperpigmentation macules without alopecia (C, D)
