Individuals with Fitzpatrick skin types IV to VI are becoming a larger proportion of our patient base. Although acne scarring can be difficult to treat in all skin types, it presents a greater challenge in darker skin types due to an increased risk for scarring and postinflammatory hyperpigmentation (PIH). Few studies have focused on infrared laser treatment of acne scarring in darker skin types. In this study, we assess the efficacy and side-effect profile of a 1450-nm diode laser for the treatment of acne scars in participants with Fitzpatrick skin types IV to VI. Our findings show the nonablative 1450-nm diode laser to be safe and effective in improving the appearance of atrophic acne scars in darker skin types. Postinflammatory hyperpigmentation was a common occurrence.

Background: Keloid is a benign skin tumor that result from abnormal wound healing and excessive collagen deposition. The pathogenesis is believed to be linked to genetic predisposition and immune imbalance, although the precise mechanisms remain poorly understood. Current therapeutic approaches may not consistently yield satisfactory outcomes and are often accompanied by potential side effects and risks.

Background: In data-sparse areas such as health care, computer scientists aim to leverage as much available information as possible to increase the accuracy of their machine learning models' outputs. As a standard, categorical data, such as patients' gender, socioeconomic status, or skin color, are used to train models in fusion with other data types, such as medical images and text-based medical information. However, the effects of including categorical data features for model training in such data-scarce areas are underexamined, particularly regarding models intended to serve individuals equitably in a diverse population.

Objectives: There is no consensus on elective lymphatic dissection of the parotid and neck for nonmelanoma skin cancer (NMSC) due to challenges in detecting occult spread to these regions. This study aimed to summarize clinical data and evaluate correlations between risk factors, nodular metastasis, and the need for elective parotidectomy in patients with cutaneous squamous cell carcinoma (CSCC), Merkel cell carcinoma (MCC), and apocrine carcinoma (AC) of the head and neck, all with clear surgical margins and negative imaging results for regional metastases.
Study Design: We retrospectively reviewed 166 patients with CSCC, one with MCC, and one with AC of the head and neck, all treated surgically between September 2006 and July 2022.

Recently, photodynamic therapy (PDT) which involves a photosensitizer (PS), a special drug activated by light, and light irradiation has been widely used in treating various skin diseases such as port-wine stain as well as cancers such as melanoma and non-melanoma skin cancers. PDT comprises two general steps: the introduction of PS into the body or a specific spot to be treated, and the irradiation process using a light source with a specific wavelength to excite the PS. Although PDT is gaining great attention owing to its potential as a targeted approach in the treatment of skin cancers, several limitations still exist for practical use.
