Abstract
A 53-year-old male presented to the clinic for "bilateral temporal dark yellow plaques with pruritus for 8 years." The patient had bilateral temporal dark yellow plaques without obvious inducement 8 years ago and did not see doctors at that time. Five years ago, bilateral temporal skin lesions gradually increased and were accompanied by severe itching. On top of them, there were several blackheads and pimples with the size of needle tips up to the size of rice grains. After compression, lipid substances could be excreted and there was a clear odor. The patient sought medical attention at a local hospital, but the diagnosis and medication were unknown, and the symptoms did not improve. In the past month, due to the aggravation of skin lesions and itching that affected sleep, he visited the outpatient clinic of our hospital again. The patient was diagnosed with nodular elastoidosis with cysts and acne and was given 5% peroxybenzoyl gel and 0.1% tretinoin cream for topical use. After 2 weeks, the itching symptoms of the patient were significantly reduced.
