Treatment of Behçet disease with oral roflumilast: an observational study.

Background: Mucocutaneous Behçet disease often presents a therapeutic challenge. Roflumilast has shown promise in the treatment of other inflammatory dermatological conditions.

Objectives: The objective of this study was to evaluate the characteristics, effectiveness and safety of roflumilast in the treatment of Behçet disease-associated aphthosis in routine clinical practice.

MicroRNAs expression associated with aggressive clinicopathological features and poor prognosis in primary cutaneous melanomas.

Several studies have focused on identifying microRNAs involved in the pathogenesis of melanoma. However, its association with clinicopathological features has been scarcely addressed. The aim of this study is to identify microRNAs expression profiles related to aggressive clinicopathological and molecular features, and to analyze the association with melanoma survival.

Accuracy of SCORTEN and ABCD-10 to predict mortality and the influence of renal function in Stevens-Johnson syndrome/toxic epidermal necrolysis.

Epidermal necrolysis (EN) compromises a spectrum of life-threatening dermatoses (Stevens-Johnson Syndrome [SJS], overlap syndrome and toxic epidermal necrolysis [TEN]). Currently, no active therapeutic regimen with unequivocal benefit exists for SJS/TEN. SCORTEN is the widely-used prognostic scale specific for SJS/TEN.

Apocrine hidrocystoma on the nipple: the first report in this unusual location.

Apocrine hidrocystoma is a rare, benign, cystic tumor of the apocrine sweat glands. They are most commonly located around the eyes and may also be found on the scalp and neck. However, despite the fact that the nipple and areola contain numerous apocrine sweet glands, apocrine hydrocystomas have not been described previously in this area to the best of our knowledge.

Juvenile melanocytic acral nevus: A comparative study between MANIAC and non-MANIAC nevus and its clinicopathological characteristics.

Background: Melanocytic acral nevi have a series of distinguishing features, including their location, patient age at onset, clinical progression, and histological findings. In particular, histopathological analysis often reveals a melanocytic acral nevus with intraepidermal ascent of cells (MANIAC nevus), which in some cases can be mistaken for atypia or malignancy.

Aim: This study describes the clinicopathological characteristics of acral nevi in patients under 18 years old and contrasts the clinical and histological features between MANIAC vs non-MANIAC nevi.

Cytoimmunofluorescence Diagnosis in Surgically Induced Pemphigus Foliaceus.

Pemphigus foliaceus is an autoimmune bullous disease with autoantibodies against desmoglein 1. Case reports of pemphigus after surgery have also been described, which may simulate an infection of the surgical wound, a contact dermatitis, or even a tumor recurrence. Cytoimmunofluorescence can help to establish a rapid diagnosis.
