چکیده
Background: No clinical clues to differentiate between extrinsic atopic dermatitis (eAD) and intrinsic atopic dermatitis (iAD). Aim: To compare presence of Pityriasis Alba (PA) in patients with extrinsic and intrinsic type of AD. Subjects & Methods: IL-4 and Ig-E were measured in 85 Patients’ serum with enzyme linked immune sorbent assay (ELISA). Forty three patients with (eAD) (group I) (n=43) and forty two patients with (iAD) (group II) completed the study (n=42). Results: There was statistically significant correlation between PA and (eAD). Conclusion: Pityriasis Alba could be used as a pathogenic clue in differentiating extrinsic AD from intrinsic AD.
