    Dermoscopy-guided surveillance in xeroderma pigmentosum: A retrospective analysis
    (Galenos Publishing House, 2025) Oraloğlu, Göktürk; Duman, Nilay; Yaman, Banu; Akalın, Taner; Karaarslan, Işıl
    Aim: Xeroderma pigmentosum (XP) is a life-threatening disease characterized by high rates of skin cancers. Therefore, it is important to establish key guidelines for the follow-up of these patients to detect skin cancers, particularly melanoma, at an early stage. Materials and Methods: This is a retrospective study that includes the analysis of the follow-up findings and medical records of XP patients who were followed up with whole-body skin examination, dermoscopic examination, and whole-body photographing between 2003 and 2021 in the Dermato Oncology unit of Ege University Department of Dermatology. Results: Of the 19 patients, 10 were male and 9 were female. The youngest patient was 5 years old, while the oldest patient was 64 years old. A total of 234 lesions were excised from these patients. Seventeen melanomas were excised, including 11 in situ, with a Breslow thickness of less than 1 mm. The highest Breslow scores belong to patients who missed their appointments or did not receive follow-up care previously. Conclusion: It was observed that regular full-body skin examinations, whole-body photography, and dermoscopic monitoring performed at 3-month intervals in XP patients are helpful in detecting skin malignancies at an early stage and preventing unnecessary excisions.

    In vivo reflectance confocal microscopy for detecting cutaneous metastasis in breast cancer
    (Mattioli 1885, 2025) Duman, Nilay; Yaman, Banu; Oraloğlu, Göktürk; Kararaslan, Işıl
    A 45-year-old female with a history of invasive ductal breast carcinoma (IDBC) presented with an asymptomatic erythematous nodule on the right mastectomy scar. Dermos copy revealed erythematous peripheral border, polymor phous and atypical vessels, focal scaling, and multiple white structureless areas appearing as white clods and strands. Reflectance confocal microscopy (RCM) revealed a normal epidermis with a preserved honeycombed pattern, with der mal tumoral clusters of varying sizes consisting of highly polymorphous hyporeflective cells with different sizes and shapes.

    Staphylococcus aureus as a signature species of skin microbiome in actinic keratosis and squamous cell carcinoma: A narrative review
    (Wolters Kluwer, 2025) Duman, Nilay; Oraloğlu, Göktürk; Ece, Deniz; Caner, Ayşe
    Cutaneous squamous cell carcinoma (cSCC) is a common type of skin cancer and the second most common type of nonmelanoma skin cancer. Actinic keratosis (AK) is a premalignant lesion that can progress to cSCC over time. AK and cSCC are associated with microbial dysbiosis and an increased abundance of the bacterium Staphylococcus aureus. Although AK and cSCC are highly colonized with S. aureus, a bacterium of the skin microbiota, it is not yet known whether this bacterium is associated with cancer development. Here, we analyze the studies on the relationship between S. aureus and keratinocytic skin neoplasia, evaluating the contribution of S. aureus to the development and prognosis of cSCC and AK lesions. The overabundance of S. aureus and the compounds secreted by this bacterium can induce cancer‑promoting changes in skin cells. The presence of high amounts of certain S. aureus strains in premalignant skin lesions may constitute a protumorigenic stimulus by inducing oxidative stress and DNA damage and downregulating DNA repair mechanisms. S. aureus associated with AK and cSCC can trigger keratinocytes to produce inflammatory cytokines typically upregulated in cSCC. These circumstances also suggest a potential specific involvement of S. aureus in the progression from AK to cSCC.
