Special Issue Information

Dear Colleagues,

Malignant cutaneous adnexal neoplasms are rare but clinically significant tumors arising from hair follicles, sebaceous glands, apocrine glands, and eccrine glands. Despite their histologic diversity and aggressive potential, the molecular mechanisms underlying their pathogenesis remain poorly understood compared with more common skin cancers. Recent advances in genomic and transcriptomic profiling have begun to uncover recurrent genetic drivers, including TP53 mutations, PI3K/AKT/mTOR signaling alterations, mismatch repair deficiencies, and aberrations in Hedgehog and Wnt/β-catenin pathways. These findings not only provide insights into tumor initiation and progression but also highlight potential targets for precision medicine.

Given their rarity, malignant adnexal tumors serve as a valuable model to study lineage-specific tumorigenesis, differentiation pathways, and tumor microenvironmental influences. This Special Issue aims to gather contributions focused on the molecular and cellular biology of malignant adnexal neoplasms, including mechanistic studies, molecular classification efforts, and integrative analyses linking genetics, epigenetics, and tumor–stroma interactions. Reviews that synthesize current knowledge and identify future research priorities are also welcome. By bringing together cutting-edge research, this collection seeks to advance our understanding of malignant adnexal neoplasms and shed light on their unique role in skin tumor biology.

We look forward to receiving your contributions.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Biology is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). 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.
