case_images: Similar hyperpigmented patches developed and progressed on her chest and flank over half a year (Figure 1). Some of the pigmented patches had become surrounded with erythema two weeks prior to presentation (Figure 1).

case_images: The histology of lesional skin from a hyperpigmented patch and surrounding erythema both showed prominent epidermotropism and atypical lymphocytes (small to medium-sized hyperchromatic indented nuclei) aligning along the basal layer and perivascular space with dermal melanophages (Figure 2).

case_images: A therapy with oral 8-methoxypsoralen three times a week along with a potent topical corticosteroid agent (clobetasol propionate). After 8 weeks of treatment, the erythematous lesions regressed with no development of new lesions, and the involved pigmented area had reduced from 10% to 6% of the total body surface area (Figure 3).
