CME Credits: 1.00
Released: 2021-04-28
A man in his 60s presented to our dermatology outpatient department with a 5-year history of pruritic papules on the right side of his lower back. He was otherwise healthy, with no family history of a similar condition. Physical examination results showed multiple dome-shaped, skin-colored, firm papules on his right lower back, arranged in a blaschkoid distribution (A). The lesions varied in size, with some coalescing into irregular-shaped, larger papules. Telangiectasis could be seen on some of the lesions. A skin biopsy was performed on his back and submitted for further histopathologic analysis (B and C).
