A 50-year-old woman presented with a several-year history of pruritus in the axillae. Dermatologic examination revealed numerous skin-colored, firm papules arranged in parallel lines (Figure 1 and Figure 2) and surrounded by normal skin. Some of them had a central umbilication, with an atrophic hair. There were no similar lesions on the rest of the body. The patient was in good general health; she did not take any medication. To her knowledge, nobody in her family had a similar dermatologic condition. A biopsy specimen was obtained to confirm the clinical diagnosis (Figure 3).
