BACKGROUND Eccrine porocarcinoma(EPC)is a rare skin tumor that mainly affects the elderly population.Tumors often present with slow growth and a good prognosis.EPCs are usually distinguished from other skin tumors using histopathology and immunohistochemistry.However,surgical management alone may be inadequate if the tumor has metastasized.However,currently,surgical resection is the most commonly used treatment modality.CASE SUMMARY A seventy-four-year-old woman presented with a slow-growing nodule in her left temporal area,with no obvious itching or pain,for more than four months.Histopathological examination showed small columnar and short spindle-shaped cells;thus,basal cell carcinoma was suspected.However,immunohistochemical analysis revealed the expression of cytokeratin 5/6,p63 protein,p16 protein,and Ki-67 antigen(40%),and EPC was taken into consideration.The skin biopsy was repeated,and hematoxylin and eosin staining revealed ductal differentiation in some cells.Finally,the patient was diagnosed with EPC,and Mohs micrographic surgery was performed.We adapted follow-up visits in a year and not found any recurrence of nodules.CONCLUSION This case report emphasizes the diagnosis and differentiation of EPC.

Objective: Elderly atopic dermatitis (AD) is a newly identified subtype of AD. Whether specific diagnostic criteria are needed for elderly AD has been debated. This study aimed to propose diagnostic criteria for elderly AD and evaluate the sensitivity.Methods: A hospital-based study was conducted. We screened the clinical features of 1,312 patients with AD of different ages in 1 cohort and proposed a set of diagnostic criteria for elderly AD. The criteria were then validated in another cohort of 223 patients clinically diagnosed with elderly AD by dermatologists specialized in AD to examine the diagnostic sensitivity compared with other criteria by chi-square test.Results: Based on the patients’ clinical features, a set of diagnostic criteria for elderly AD were proposed. The new diagnostic criteria showed significantly higher sensitivity than the classical diagnostic criteria (P dermatology Academy criteria, and the United Kingdom Working Party criteria, respectively.Conclusion: The newly proposed criteria for elderly AD yielded high diagnostic sensitivity, particularly for mild and moderate AD.

Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disease. The main initiating mechanisms of AD are disruptions in the skin microbiota, dysfunction of the skin barrier, and predominantly elevated type 2 immune responses.Cutibacterium acnes (C. acnes) is a commensal bacterium that is ubiquitous and predominant in healthy skin and shows intraspecific subtype diversity. The abundance ofC. acnes is closely related to the sebum secreted by sebaceous glands.C. acnes has long been considered a proinflammatory skin bacterium that drives the development of acne vulgaris. Growing evidence indicates thatC. acnes promotes skin microbiota homeostasis and skin barrier maintenance; however, the potential role ofC. acnes in AD remains largely unexamined. This review provides the latest information on the distribution ofC. acnes and its phylotypes in healthy skin and AD as well as an overview of the possible role ofC. acnes in the pathophysiological pathways underlying AD. Additionally, the review focuses on new evidence regarding the protective functions ofC. acnes and its metabolites in AD and discusses the potential for therapeutic applications.

Background:Pathological scars are a disorder that can lead to various cosmetic,psychological,and functional problems,and no effective assessment methods are currently available.Assessment and treatment of pathological scars are based on cutaneous manifestations.A two-photon microscope(TPM)with the potential for real-time non-invasive assessment may help determine the under-surface pathophysiological conditions in vivo.This study used a portable handheld TPM to image epidermal cells and dermal collagen structures in pathological scars and normal skin in vivo to evaluate the effectiveness of treatment in scar patients.Methods:Fifteen patients with pathological scars and three healthy controls were recruited.Imaging was performed using a portable handheld TPM.Five indexes were extracted from two dimensional(2D)and three dimensional(3D)perspectives,including collagen depth,dermo-epidermal junction(DEJ)contour ratio,thickness,orientation,and occupation(proportion of collagen fibers in the field of view)of collagen.Two depth-dependent indexes were computed through the 3D second harmonic generation image and three morphology-related indexes from the 2D images.We assessed index differences between scar and normal skin and changes before and after treatment.Results:Pathological scars and normal skin differed markedly regarding the epidermal morphological structure and the spectral characteristics of collagen fibers.Five indexes were employed to distinguish between normal skin and scar tissue.Statistically significant differences were found in average depth(t=9.917,P<0.001),thickness(t=4.037,P<0.001),occupation(t=2.169,P<0.050),orientation of collagen(t=3.669,P<0.001),and the DEJ contour ratio(t=5.105,P<0.001).Conclusions:Use of portable handheld TPM can distinguish collagen from skin tissues;thus,it is more suitable for scar imaging than reflectance confocal microscopy.Thus,a TPM may be an auxiliary tool for scar treatment selection and assessing treatment efficacy.
