Juvenile dermatomyositis (JDM) is associated with many distinguishing features including cutaneous calcinosis, vasculitis, and ulcerated lesions. In this case, we describe an unusual presentation in a 12-year-old girl who had muscle weakness along with linear morphea over the right upper and lower extremities with overlying lichen sclerosus and calcinosis cutis. Of interest, these initial cutaneous manifestations occurred years before onset of myositis.

Linear focal elastosis (LFE), also known as elastotic striae, is a rare cutaneous condition characterized by abnormal or increased deposition of elastic fibers in the dermis. It typically presents as asymptomatic, atrophic, or hyperpigmented linear bands, most commonly on the back. We report a case of LFE in a 15-year-old healthy male who presented with multiple asymptomatic, parallel hypopigmented linear bands with hyperpigmented borders on his back.

Adipose-derived mesenchymal stem cells (ADMSCs) offer a multifaceted approach to treating immune-mediated skin diseases by modulating the immune system and promoting tissue regeneration. Specifically, their ability to differentiate into multiple cell types such as keratinocytes and fibroblasts, modulate immune responses, and release growth factors and cytokines underscores their potential in treating a wide range of immune-related skin conditions. ADMSCs significantly reduced various aspects of psoriasis, including scaling, thickness, and erythema.

The serine protease 23 (PRSS23) is a highly conserved member of trypsin-like serine proteases, which are associated with numerous essential processes, including digestion, blood coagulation, fibrinolysis, development, fertilization, apoptosis, and immunity. Original reports on PRSS23 unfolded not earlier than 2006 when a molecular biology study characterized and described PRSS23 as an ovarian protease. Then, in 2012, another important study was published linking PRSS23 with proliferation of breast cancer cells by an estrogen receptor 1 (ESR1)-dependent transcriptional activation of the serine protease.

: Localized scleroderma (LoS) is a chronic autoimmune condition marked by cutaneous fibrosis and persistent inflammation. Modulating the activation of inflammatory cells and fibroblasts remains a central strategy in LoS treatment. We investigate the anti-fibrotic effects of Annexin A5 (AnxA5), identified as a key inflammatory component in fat extract, and assess its therapeutic efficacy.

Congenital linear scleroderma (CLS) is a rare connective tissue disorder characterized by unilateral linear induration that can lead to restricted mobility and limb deformities. Various treatments have been proposed, including D-penicillamine, phototherapy, oral vitamin D, and immunosuppressants such as methotrexate (MTX), cyclosporine, and interleukin-6 (IL-6) inhibitors. We present the case of a 14-year-old female patient with refractory CLS, whose condition continued to worsen despite treatment with tocilizumab, mycophenolate mofetil (MMF), and MTX.
