Scar sarcoidosis is a rare form of cutaneous sarcoidosis where preexisting scars become infiltrated with non-caseating granulomas. Multiple events such as trauma, local injection, operation have been known to develop scar sarcoidosis. A 46-year-old woman presented with erythematous papules on her left upper eyelid. She was diagnosed as acute lymphoblastic leukemia (ALL) 10years ago and received blepharoplasty (double eyelid surgery) 20 years ago. To rule out the leukemia cutis, we performed the skin biopsy. Histological examination showed dense non-caseating granulomatous infiltration in entire dermis, with numerous epithelioid cells consistent with sarcoidosis. Chest X-ray and blood test showed no evidence of systemic sarcoidosis. There are several reports about the scar sarcoidosis after blepharoplasty and sarcoidosis developed in ALL patients, respectively. However, there is no report on the scar sarcoidosis occurring on blepharoplasty scar in ALL patients 20 years of after surgical procedure. When firm papules appear on the scar site in leukemia patients, the skin biopsy is needed to exclude the scar sarcoidosis.
