Long-Standing Remission After Tildrakizumab Treatment in a Case of Refractory Type I Pityriasis Rubra Pilaris in a Breast Cancer Patient.

Pityriasis rubra pilaris (PRP) is a rare chronic inflammatory skin disease characterised by follicular keratotic papules and perifollicular erythema coalescing into orange-red scaly plaques, and palmoplantar keratoderma. Characteristic islands of sparing are usually observed. A standardised therapeutic approach is lacking owing to the infrequent occurrence of this disease.

The role of reflectance confocal microscopy in the diagnosis of eccrine poroma: A retrospective case-control study.

Eccrine poroma (EP) is a rare benign adnexal tumor that may mimic benign or malignant tumors and differential diagnosis may be difficult under clinical and dermoscopic examination. Reflectance confocal microscopy (RCM) examination may add important information to diagnosis and subsequent management of solitary lesions for which dermoscopy can be challenging. The aim of the present study was to investigate features of EP at RCM in order to detect the characteristics that might aid in the differential diagnosis of EP versus other solitary lesions (benign or malignant).

Guselkumab for the treatment of psoriasis: a 60-week real-life multicenter retrospective experience.

Background: Real-world data for guselkumab, the first interleukin-23 inhibitor approved to treat moderate-to-severe psoriasis, are scarce. This study represents the first 60-week, real-life, multicenter, retrospective experience to investigate the effectiveness, safety, tolerability, and drug retention of guselkumab in psoriatic patients.

Research Design And Methods: Clinical information was collected at baseline and at weeks 12, 24, 36, 48, and 60.

Use of Apremilast® in the psoriasis treatment: a real-life multicenter Italian experience.

Background: Apremilast (Amgen, Thousand Oaks, CA, USA) is the first small molecule approved for the treatment of moderate-to-severe psoriasis in adult patients; however, real-life data are still limited. We investigated the effectiveness and safety of this drug in a multicenter real-world setting.

Methods: We retrospectively reviewed data from all psoriatic patients who received at least one dose of Apremilast (Amgen) and collected demographic data and medical history at baseline and periodically for 36 months.

The presence of eccentric hyperpigmentation should raise the suspicion of melanoma.

Background: Melanocytic lesions with eccentric hyperpigmentation (EH), even though without other dermatoscopic features of melanoma, are often excised.

Objective: Aiming to understand whether the EH in a pigmented lesion is an accurate criterion of malignancy, we evaluated the capability of two evaluators, with different expertise, to correctly diagnose a melanoma when analysing a given lesion in toto versus a partial analysis, with only the EH or the non-hyperpigmented portion (non-EH) visible.

Methods: Dermatoscopic images of 240 lesions (107 melanomas and 133 nevi) typified by EH were selected.

The role of ultrasound examination for early identification of lymph-node metastasis of cutaneous squamous cell carcinoma: results from a single institutional center.

Background: Metastasis from cutaneous squamous cell carcinoma (cSCC) mainly involve the regional nodal basin, with an incidence ranging from 2-4% until 15% in case of high-risk tumors. When dealing with high-risk cSCC, ultrasound examination is recommended every 3-4 months during follow-up. We aimed to determine the role of US examination in the early diagnosis of nodal metastasis from cSCC.

Ixekizumab Effectiveness and Safety in the Treatment of Moderate-to-Severe Plaque Psoriasis: A Multicenter, Retrospective Observational Study.

Background: Ixekizumab (anti-IL-17A) is a biological agent used for the treatment of moderate-to-severe psoriasis. Real-life data on the effectiveness and safety of ixekizumab are currently scarce.

Objective: The objective of this study was to evaluate the effectiveness and safety of ixekizumab in a cohort of psoriatic and psoriatic arthritis patients.

The influence of MC1R on dermal morphological features of photo-exposed skin in women revealed by reflectance confocal microscopy and optical coherence tomography.

Background: The melanocortin 1 receptor (MC1R) gene is one of the major determinants of skin pigmentation. It is a highly polymorphic gene and some of its polymorphisms have been related to specific skin phenotypes, increased risk of skin cancers and skin photoageing. Currently, its contribution to changes in dermal features in photo-exposed skin is unknown.

Moderate to severe psoriasis: a single-center analysis of gender prevalence.

Background: Psoriasis is a chronic, relapsing disease and most epidemiological studies include selected patients undergoing systemic therapies only. Epidemiological data suggest that psoriasis affects 2-3% of the general population, and that men and women are equally affected. The objective was to identify differences in gender for disease severity, patient characteristics and comorbidities in patients with moderate to severe psoriasis, independent of therapy.
