Blaschkoid psoriasis: An unusual variant of psoriasis that needs to be diagnosed early and treated aggressively

摘要

A 31-year-old male presented with erythematous eruptions on the right side of the body since childhood. Physical examination revealed linear erythematous scaly papuloplaques at the right chest, abdomen, waist, suprapubic area, buttock, and back along Blaschko lines with a marked midline demarcation (Figure 1A,B). Similar skin lesions were distributed from the right thigh to the right ankle and from the right arm to the right thumb (Figure 1C,D) in a linear pattern along Blaschko lines. The patient's scalp, nails, and oral mucosa were all normal.
