Introduction: Seborrheic dermatitis (SD) is a chronic-recidive inflammatory skin disorder with predilection in areas rich of sebaceous gland. The most common clinical manifestations are pruritus and scales. Although SD can be diagnosed without special tools, other examinations may be needed to determine additional specific therapy. Trichoscopy is one of the noninvasive tools which can help to diagnose SD as it can provide the microstructure view of the scalp. Materials and Methods: This descriptive study was conducted to explore the trichoscopic features of SD and its characteristics. There were 96 SD patients enrolled in this study. The scalp was divided into four areas, and each area was scored based on Seborrheic Area Severity Index, comprising erythema, desquamation, number of papules, and percentage of lesion area. The most severe area was examined with a trichoscopy to observe the characteristics of hair and scalp. The association between trichoscopic findings and SD severity was analyzed with Fisher's exact test. Results: Overall, the participants were 36% males and 64% females with the mean age of 30 (13–70) years old. Based on the trichoscopic examination, the most common findings were thick hair shafts (72%), white scales (69%), arborizing thin vessels (38%), yellowish area (36%), and structureless red area (19%). These findings were not significantly different between mild and moderate SD ( P > 0.05). Conclusion: Considering the merits and demerits of trichoscopic examination, it can be helpful to aid the diagnosis of SD. Further studies in Asian population with greater sample size are needed to demonstrate more significant result.
Skin cancer is a global health concern due to its growing incidence and high mortality rate. The most common therapeutic modalities in skin cancer include surgery, radiotherapy, and chemotherapy. However, those therapies do not specifically target cancer cells and may damage healthy tissues. Cancer induces immune response by releasing soluble antigens and danger signals caused by tumor cellular stress or death, while the immune system continuously monitor and control malignant proliferation through cancer immunoediting. Therefore, targeting this mechanism is a promising approach to manage cancer, especially those unresponsive to conventional therapies. Immunotherapy is a specific therapy that manipulates the immune system to fight the disease. Previous studies have shown promising results in its clinical use in melanoma and non-melanoma skin cancer (NMSC). However, its potential toxicity and tolerability may pose significant obstacles in developing effective cancer immunotherapy. Biomedical, immunological, and clinical research in skin cancer is still needed to elaborate further on its pathogenesis and design safe and effective therapy for each skin cancer.

Seiring dengan bertambahnya usia seseorang, kulit sebagai jaringan terluar dari tubuh manusia akan memberikan gambaran paling terlihat dari proses penuaan. Penuaan kulit dipengaruhi oleh dua faktor yaitu faktor intrinsik dan faktor ekstrinsik. Faktor intrinsik terjadi secara alamiah dan berkaitan dengan proses degenerasi seluler. Faktor ekstrinsik berkaitan dengan pajanan sinar matahari, rokok, dan polusi udara. Penyebab utama penuaan kulit akibat faktor ekstrinsik berupa pajanan kronik sinar ultraviolet dikenal sebagai photoaging. Tanda klinis photoaging dapat bervariasi, namun yang sering ditemukan berupa perubahan pigmentasi dan keriput. Saat ini telah tersedia lebih dari 100 instrumen penilaian penuaan kulit menggunakan fotografi, dermoskopi, dan alat diagnostik multifungsi namun masih belum ada yang dianggap sebagai baku emas. Tinjauan pustaka ini bertujuan untuk membahas berbagai instrumen penilaian photoaging yang sering digunakan dalam praktik klinis sehari-hari dan karakteristik dari masing-masing instrumen tersebut.
