A 71-year-old Caucasian female patient with no prior history of skin cancer presented with a red, painful, and enlarging plaque on her right breast for several weeks. This lesion has not been treated in the past and she denies genital lesions.\nPhysical exam revealed a hemorrhagic plaque with subtle surrounding atrophic changes on her right medial breast (Figure ). Punch biopsy of the plaque revealed hyperkeratosis with epidermal atrophy, prominent papillary dermal edema with homogenization, and extensive hemorrhage at the dermoepidermal junction, suggestive of LSA (Figure ). Unfortunately, the patient was lost to follow-up and did not receive treatment.
A 26-year-old male presented with multiple hypopigmented atrophic macules over the upper and lower limbs since one month []. Dermoscopy revealed whitish structureless areas (WSA), comedo like openings (CLO) [] and dotted vessels arranged in a net-like pattern [].
