REPORT OF A CASE
A 35-year-old man presented to the University of Michigan, Ann Arbor, dermatology outpatient clinic for evaluation of an asymptomatic rash on his left pectoral region. This condition began approximately one year prior to examination, and was felt by the patient to be secondary to trauma sustained from a tree that had fallen on his chest. Subsequently, the patient noticed a nodule on the anterior aspect of his chest. The nodule was eventually replaced by a slowly spreading red-brown reticulated eruption with the development of alopecia in the same location. No further papules or nodules were noted to develop. During the year prior to presentation, the eruption would decrease slightly in size, but it never disappeared. There was no prior history of radiation therapy, heat application, or photoexacerbation of the lesion. Pertinent medical history included the diagnosis of rheumatoid arthritis, which was made concomitantly with the presentation
