ALMEIDA JR, Hiram Larangeira de and JANNKE, Heitor Alberto. Sarcoidosis in previous scars. An. Bras. Dermatol. [online]. 2004, vol.79, n.1, pp.79-82. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962004000100009.
The authors report the case of a 20-year-old male patient, who presented sudden infiltration of previous scars on the forehead, which were due to an accident occured four years ago. Light microscopy showed noncaseating, nonconfluent granulomas with few lymphocytes; special stains for fungi and mycobacteria were negative, as well as examination under polarized light. Radiologic examination of the chest, ophthalmologic screening and calcemia were normal, which lead to the diagnosis of a sarcoidosis in previous scars without systemic involvement. There was a good response to treatment with intralesional steroids.
