Scar sarcoidosis is a dermatosis which develops on long-standing cutaneous scars. They become inflamed and infiltrated, giving rise to typical purplish-red lesions which turn brown as they fade. Between 20% and 35% of patients with systemic sarcoidosis have skin lesions, but cutaneous sarcoidosis can also occur without systemic disease, and is therefore of diagnostic importance. The case of a 60-year-old woman with “scar sarcoidosis” on preexisting cutaneous scars, without signs or symptoms of systemic disease at the time of diagnosis, is reported. Histological examination showed, in the reticular dermis, non-caseating epithelioid cell tubercles, so-called “naked” for the low number of surrounding lymphoid cells. The patient did not receive any therapy, because of the exclusive localization of the disease to the skin. After a follow-up period of 12 months, no recurrence of cutaneous lesions and no systemic involvement have been observed. In conclusion, “scar sarcoidosis” is a disease characterized by unpredictable clinical onset and evolution; the importance of accurate staging and follow-up of the patient for the early diagnosis of systemic disease is emphasized.
