Description
Jeong and colleagues test a stain as a tie breaker between psoriasis and atopic dermatitis. The two skin diseases can look alike under the microscope when both show thickened, psoriasis like growth. The stain targets EMA, a marker of skin cell maturity, rarely checked in inflamed skin. Their 2026 study reviews fifteen patients with each disease and compares signs, microscope features, and stain strength and spread.
The diseases split on several signs. Thickened, leathery skin favored dermatitis, and wide tiny vessels favored psoriasis. A white cell type called eosinophils appeared in dermatitis only. The stain split them best. Strong EMA staining showed in three quarters of dermatitis cases but almost no psoriasis cases. Wide spread staining across the skin layer also favored dermatitis. Average stain strength ran about twice as high in dermatitis. Because weak staining overlaps, the authors advise using the stain as support, not a verdict.
