Seborrheic dermatitis and anti‐COVID‐19 masks
„In Milan, Italy, after the end of the lockdown period (March and April 2020), we observed several patients with seborrheic dermatitis (SD) who showed a more or less important worsening of their disease. In a group of 43 patients with SD who had been visited from December 2019 to February 2020, a worsening in 20 of them (46.5%) was seen. They were 15 males (75%) and 5 females (25%), with an age ranging from 23 to 48 years (mean age: 36.7 years). All patients used anti‐coronavirus‐19 (COVID‐19) face mask for 6‐10 hours per day; 7 out of 20 patients (35%) were physicians, obstetricians, or nurses. According to the clinical point of view, the worsening was characterized by increased erythema and desquamation (Figures 1 and 2). Fourteen out of 20 patients (70%) stated that also itching worsened.“
