Linear and whorled nevoid hypermelanosis is a rare skin pigmentation disorder, characterized by linear streaks and whorls of hyperpigmented macules along Blaschko’s lines. Lesions are commonly restricted to the trunk, neck, and extremities, sparing the face, palms, soles, and mucosae. Associated with this, certain cardiovascular, musculoskeletal, neurological, and developmental anomalies have been reported in the literature. Herein, we present a rare case of linear and whorled nevoid hypermelanosis involving the face, with musculoskeletal, genital, aural, and ocular abnormalities.

Background. Freckles and solar lentigines are epidermal pigmentation disorders that affect the face and impact the quality of life of affected individuals. Aims. We aimed to observe and evaluate the clinical effectiveness of a 730 nm picosecond laser for the treatment of freckles and solar lentigines. Methods. We retrospectively collected patient information on freckles and solar lentigines and observed and evaluated the clinical outcome of a 730 nm picosecond laser. These included lesion clearance and recurrence rates, adverse reactions, and patient satisfaction. Results. Fifty cases of freckles and solar lentigines reported between January 1, 2022, and July 1, 2022, were included. All patients received two 730 nm picosecond laser treatments. The lesion clearance rates after one and two treatments were 53.1% and 78.4%, respectively, and the rates after one and six months of treatment were 78.7% and 78.4%, respectively. 90% of the patients reported ≥95% clearance of lesions after six months via a questionnaire survey. Among the patients, 86.0% were satisfied with their treatment. Postinflammatory hyperpigmentation occurred in two patients, both of whom had Fitzpatrick skin type IV. There was no recurrence of lesions. Conclusions. The 730 nm picosecond laser treatment for freckles and solar lentigines has the advantages of a high clearance rate, low recurrence rate, and high patient satisfaction. This trial is registered with ChiCTR2200058573.

Background and Objective: Unwanted hair growth is a discomforting issue affecting both genders. People have tried various methods to get rid of this situation. This study aims to evaluate the efficacy and safety of a combined Alexandrite and Nd:YAG laser treatment for permanent hair removal, drawing insights from existing literature. Materials and Methods: This study included a total of 2127 patients (302 males, 1825 females) aged 18 -65, with complete data, who underwent hair removal treatment between December 2018 and April 2021. These patients were treated using the Duetta laser system (Quanta system, Samarate, Italy), combining Alexandrite 755 nm and Nd:YAG 1064 nm wavelengths. The patients' skin types were classified according to the Fitzpatrick classification scale. Target area/areas for laser hair removal was/were determined. Laser parameters, pulse counts, pain levels assessed through the Visual Pain Scale (VPS), and patient satisfaction were documented based on skin types. Findings: Across various skin types, Types I -II exhibited the highest treatment success rates (87%), with the axillary region achieving the highest rate (83%) and the face region achieving the lowest rate (75%). Pain scale analysis indicated that 98% of patients tolerated the procedure well. Patient satisfaction levels exceeded 90%. Evaluation of complication rates revealed minimal occurrences. Conclusion: The combined Alexandrite and Nd:YAG laser system demonstrates both efficacy and safety across diverse skin types, attributed to its notable success rates, minimal adverse effects, and high patient tolerance.
