Special Issue Information

Dear Colleagues,

Inflammatory skin diseases represent uniquely accessible tissues, useful in decoding how epithelial stress signals shape innate and adaptive immunity. For this Special Issue, we invite original research and reviews that illuminate the molecular circuits linking keratinocytes, fibroblasts, and myeloid/lymphoid cells to clinical phenotypes and treatment response. We especially welcome studies dissecting photoimmunology and autoimmunity—such as type I interferon-driven pathways in cutaneous lupus erythematosus and dermatomyositis—as well as works on chronic wounds and neutrophilic dermatoses that reveal shared and divergent mechanisms of tissue injury and repair.

Cutting-edge methodologies are encouraged, including single-cell and spatial transcriptomics, proteomics, advanced imaging, and functional models (organoids, ex vivo human skin, and in vivo systems). Translational contributions that connect mechanism to biomarkers, patient-reported outcomes, and targeted therapies are of particular interest. We also welcome method papers and datasets that enable the reproducible analysis of complex human samples.

By bringing together mechanistic and clinically grounded studies, this Special Issue will identify actionable nodes in cytokine–chemokine networks, clarify stromal–immune crosstalk, and accelerate the development of diagnostics and therapeutics to measurably improve patients’ lives.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Annular lichenoid dermatitis of youth (ALDY) is a rare lichenoid dermatosis characterized by distinctive clinical and histopathological features. Its etiopathogenesis remains poorly understood, and previously reported cases have consistently demonstrated polyclonal T-cell receptor (TCR) gene rearrangements. We report a patient with clinical, histopathological, and immunohistochemical findings consistent with ALDY in whom molecular analysis revealed monoclonal T-cell receptor rearrangement within the skin lesions. To our knowledge, this represents the first reported case of ALDY demonstrating T-cell monoclonality. This novel finding expands the current understanding of the molecular spectrum of ALDY and raises the possibility that cases with monoclonal T-cell rearrangement may represent a distinct clinicopathological variant. Based on our findings, we tentatively propose the term monoclonal annular lichenoid dermatitis of youth (MALDY) to describe this potential entity. Further studies are warranted to clarify its clinical significance and relationship to other cutaneous T-cell disorders. Full article
