Differentiating mycosis fungoides lesions from their mimickers clinically and histologically: A single tertiary center retrospective analysis in Saudi Arabia.

Objectives: To identify the clinical and histological features of MF that can assist in distinguishing MF from MF-mimicking cases. Although mycosis fungoides (MF) is the most common subtype of cutaneous T-cell lymphoma, clinicopathological correlations are required to establish an accurate diagnosis, which are currently lacking.

Methods: This retrospective observational study evaluated the clinical presentations, characteristics, and histological features of 56 patients with suspected MF who presented to our clinic between January 2018 and August 2022.

PNAd-expressing vessels characterize the dermis of CD3+ T-cell-mediated cutaneous diseases.

T-cell recruitment to skin tissues is essential for inflammation in different cutaneous diseases; however, the mechanisms by which these T cells access the skin remain unclear. High endothelial venules expressing peripheral node address in (PNAd), an L-selectin ligand, are located in secondary lymphoid organs and are responsible for increasing T-cell influx into the lymphoid tissues. They are also found in non-lymphoid tissues during inflammation.

Dermatoses due to Arabic cultural and traditional practices.

A number of social and cultural practices are prevalent in the Middle-East celebrating various occasions or to treat health conditions. These often result in dermatoses that are unfamiliar and confusing to dermatologists outside this region. This paper reviews skin manifestations emanating from traditional and ritual practices in Arab countries, particularly those from Saudi Arabia.
