Background: Cutaneous pustular disorders include generalized pustular psoriasis (GPP) and acute generalized exanthematous pustulosis (AGEP).
Objective: To identify differences between GPP and AGEP, here we immunohistochemically evaluated interleukin (IL)-36 and the IL-23/Th17 axis.
Methods: This retrospective comparative immunohistochemical study was completed using 11 biopsies of 11 cases of GPP and 11 biopsies of 11 cases of AGEP.
Background: Abnormal wound-healing after thyroidectomy with a resulting scar is a common dermatologic consultation. Despite many medical and surgical approaches, prevention of postoperative scars is challenging.
Objective: This study validated the efficacy and safety of low-level light therapy (LLLT) using an 830/590 nm light-emitting diode (LED)-based device for prevention of thyroidectomy scars.
Fractional carbon dioxide laser-assisted photodynamic therapy for patients with actinic keratosis.

Background/purpose: A relatively long incubation time is needed for photosensitizer absorption in conventional photodynamic therapy (PDT) for actinic keratosis (AK). The use of ablative CO2 fractional lasers (AFXLs) to increase drug delivery could shorten the incubation time. Here, we aimed to compare the efficacy between AFXL-assisted PDT with a short incubation time and conventional PDT for AK.

- * Researchers conducted a retrospective analysis of 100 folliculitis patients, identifying 20 with MF and 80 with NMF through tissue sampling and staining techniques.
- * Findings suggest that MF is more prevalent on the trunk and more common in males, highlighting the importance of using serial sectioning and d-PAS staining for accurate diagnosis, even if initial tests are negative.
Nipple eczema exhibits as a minor manifestation of atopic dermatitis (AD) or occurs as a single skin symptom on the nipple. To characterize the relationship between nipple eczema and AD, a clinical evaluation and an immunohistochemical study were performed. All cases of nipple eczema were confirmed histopathologically.

Objective: We evaluated the efficacy and safety of PDT with a short incubation time of ablative CO2 fractional laser pretreatment for treating Bowen disease.
