A 38-year-old Caucasian male presented with a ten-year history of back pains, dyspepsia and allergic rhinitis and conjunctivitis treated with non-steroidal antirheumatic drugs and on-demand antihystamines. During this time, slowly progressive brownish freckles and patches on the trunk and the extremities began to occur. Because the patient was an entrepreneur with a busy working schedule, he did not pursue any further medical workup. However, due to increasing back pains, he underwent regular massages, and after these treatments, the skin on the back usually became swollen, itchy and red (Fig. 1A), necessitating the use of antihystamines.
