Natural Loss-of-Function Mutations in Qa2 and NCF1 Cause the Spread of Mannan-Induced Psoriasis.

J Invest Dermatol 2021 Feb 2. Epub 2021 Feb 2.

Medical Inflammation Research, Department of Medical Biochemistry and Biophysics, Karolinska Institute, Stockholm, Sweden; The Second Affiliated Hospital of Xi'an Jiaotong University (Xibei Hospital), Xi'an, China. Electronic address:

A Case of Lichen Planus Masquerading as Guttate Psoriasis.

Cureus 2020 Oct 27;12(10):e11206. Epub 2020 Oct 27.

Dermatology, St. Anthony Hospital, Oklahoma City, USA.

Lichen planus (LP) is a chronic inflammatory disease that affects the skin, hair, nails, and mucous membranes, with variants such as drug-induced lichen planus, which is triggered by medications such as angiotensin-converting enzyme (ACE) inhibitors and antimalarials. Guttate psoriasis (GP), a clinical variant of psoriasis, is associated with streptococcal infections and presents with drop-like papules on the trunk and proximal extremities. In this report, we present a case of LP in an atypical location masquerading as GP and the importance of prompt dermatological referral to improve the patient's quality of life. Read More

Best Pract Res Clin Rheumatol 2020 12 6;34(6):101594. Epub 2020 Oct 6.

Copenhagen Center for Arthritis Research (COPECARE), Center for Rheumatology and Spine Diseases, Rigshospitalet, Glostrup, Denmark; Department of Clinical Medicine, Faculty of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark. Electronic address:

Psoriatic arthritis is a heterogenous disease affecting peripheral and axial joints, tendons, ligaments, and their insertions, in addition to the skin and the nails. The complexity of the involved structures has puzzled clinicians trying to understand the underlying pathology that leads to symptoms in order to choose the appropriate medications with different modes of actions. Imaging, mainly ultrasound and magnetic resonance imaging, allows of accurate detection of inflammatory changes in the musculoskeletal structures, which helps to avoid false positive and negative assessments.

Histological Evaluation of the Relationships Between Distal Interphalangeal Psoriatic Arthritis and Nail Psoriasis: Correlations With Anatomical Studies of the Normal Nail Unit and the Main Radiological Data Concerning Distal Interphalangeal Psoriatic Arthritis.

Am J Dermatopathol 2020 Dec;42(12):911-915

Laboratoire Central d'Anatomie Pathologique, Hôpital L. Pasteur, University of Nice, Nice, France; and.

To determine whether distal interphalangeal joint psoriatic arthritis (DIP PsA) and nail psoriasis are anatomically linked, we studied 2 fingers taken from a cadaver presenting a typical cutaneous and nail psoriasis in the setting of a dactylitis limited to the fourth toe. This comprehensive study of the inflammatory pattern of DIP PsA is discussed in the context of the controversial theory of the nail as a musculoskeletal appendage. Both the extensor and flexor entheses were focally and quite markedly infiltrated by lymphocytes and showed variable fibrosis and neovascularization. Read More

Apremilast as a target therapy for nail psoriasis: a real-life observational study proving its efficacy in restoring the nail unit.

J Dermatolog Treat 2020 Aug 3:1-5. Epub 2020 Aug 3.

Dermatologic Unit, Department of Systems Medicine, University of Rome Tor Vergata, Rome, Italy.

Purpose: Psoriasis, Psoriatic Arthritis and Nail psoriasis are chronic diseases that share a common underlying etiology of immunity dysregulation, enhanced activation of inflammatory pathways and remitting-relapsing course. Although nails represent a small percentage of the body surface involvement of this site can lead to impaired quality of life, severe discomfort and even result in permanent disability. Current therapeutic options for nail psoriasis include a variety of topical and systemic treatments although they are often reported as unsatisfactory from patients either due to their poor effectiveness or disturbing side effects.
