Introduction: Peripilar sign (PPS) is a trichoscopic sign that was first described in androgenetic alopecia (AGA) and is thought to reflect the presence of perifollicular infiltrate (PFI) in histopathology.
Objectives: To study PPS in a cohort of patients with AGA and to assess its validity as a sign indicative of PFI.
Methods: One hundred patients with AGA (confirmed by trichoscopic examination) were recruited in this cross-sectional study.

Purpose: The work aims to compare the effect of platelet-rich plasma versus fractional CO2 laser/radiofrequency versus both methods combined in treating striae distensae.
Patients & Methods: The study included ten female patients with striae alba with Fitzpatrick IV skin. Three sites of striae were chosen; one was treated with platelet-rich plasma, another with fractional CO /radiofrequency (CO/RF), and the third received both treatments.
Background: NB-UVB has long been the vitiligo management pillar with capability of achieving the main treatment outcomes; repigmentation and stabilization. Its stabilizing effect in dark skin has been debatable. However, randomized controlled trials regarding NB-UVB ability to control disease activity are lacking.

Crystalglobulinemia (CG) is a rare disorder characterized by crystallization of monoclonal immunoglobulins in the microcirculation leading to multiorgan vascular thrombosis and ischemic injury. The main cause of CG is multiple myeloma. We report a case of a 52-year-old man who presented with widespread necrotizing plaques and ulcerations.

In this intra-patient comparative study, 12 patients with stable non-segmental vitiligo (NSV) affecting the middle three fingers of one hand were included. Three variations were used in treatment of finger vitiligo lesions: minipuch grafting, melanocytes keratinocyte transplantation procedure (MKTP) preceded by cryoblebbing or full CO laser resurfacing of the recipient site.

Serum CXCL-10 was compared to interferon gamma (IFN-γ), interleukin 6 (IL-6), and IL-17 using ELISA in 55 non-segmental vitiligo patients (30 active and 25 stable) and 30 healthy controls. Marginal skin biopsy was taken for immunohistochemical evaluation of CD8+T cells and CXCL-10+ve cells.
