A Multicenter Randomized Double-Blind Vehicle-Controlled Parallel Group Phase 2 Study Evaluating the Efficacy and Safety of GN-037 Cream in Patients with Mild-to-Moderate Plaque Psoriasis.

Introduction: Topical therapies are used in almost all patients with psoriasis.

The Association between Number of Follicular Stelae and Severity and Treatment Response of Alopecia Areata Cases: A Retrospective Study.

Background: Alopecia areata (AA) is an autoimmune disease characterized by peribulbar lymphocytic infiltration, follicular miniaturization, catagen/telogen follicles, and increased follicular stelae (streamers) in skin biopsies.

Objectives: Our aim was to assess the number of follicular stelae of patients with AA and to evaluate their association with clinical type and severity and treatment response of AA.

Materials And Methods: Histopathologic features including the number of follicular stelae were recorded in skin biopsies taken from lesions of AA in 142 patients who attended our dermatology clinic from 2011 to 2017.
