Introduction: Ultraviolet-based dermoscopy may support the recognition of scabies, yet neither accuracy analyses nor data on skin of colour are available. The aim of this multicentric observational retrospective was to investigate the diagnostic accuracy of polarised and ultraviolet-induced fluorescence (UVF) dermoscopic examination in both fair and dark skin, also assessing possible differences according to the skin tone.
Methods: Consecutive patients with a diagnosis of scabies were eligible.
Article Synopsis
- The research focuses on practices related to changing scalpel blades when excising multiple skin lesions during the same appointment, particularly how beliefs about the risk of iatrogenic seeding (spreading cancer cells) influence these practices.* -
- A survey conducted with 173 medical specialists showed that surgeons tend to change blades more often than non-surgeons, with most citing concerns about seeding and training as reasons for their practices.* -
- The study concludes that while there's no strong scientific backing for regularly changing blades, significant differences in blade-changing practices exist among medical specialties, highlighting the need for standardizing evidence-based methods to improve patient care.*
The rising incidence of Basal Cell Carcinoma (BCC), especially among individuals with significant sun exposure, underscores the need for effective and minimally invasive treatment alternatives. Traditional surgical approaches, while effective, often result in notable cosmetic and functional limitations, particularly for lesions located on the face. This study explores High-Intensity Focused Ultrasound (HIFU) as a promising, non-invasive treatment option that aims to overcome these challenges, potentially revolutionizing BCC treatment by offering a balance between efficacy and cosmetic outcomes.

- Dermatoscopy is a non-invasive technique that improves skin examination for both cancerous and non-cancerous skin conditions, with new methods involving UV imaging emerging recently.
- A systematic review analyzed the principles and categorizations of these new UV techniques, examining their clinical applications, safety measures, and limitations.
- While UV dermatoscopy can enhance early detection and visualization of various skin issues, it also faces challenges like distinguishing between pigments and issues with uneven surfaces, necessitating careful use by clinicians.
Article Synopsis
- Amyloidosis is a condition where misfolded proteins deposit in the body, notably affecting the skin of individuals from the Asian subcontinent, leading to a subtype known as Primary Cutaneous Amyloidosis (PCA).
- This study focuses on identifying and confirming the dermoscopic features of two types of PCA—Macular Amyloidosis (MA) and Papular Amyloidosis (PA)—in 42 patients, primarily of skin color from a government hospital in Southeast Asia.
- Using a specialized dermoscope, researchers documented the typical characteristics of PCA to aid in accurate diagnosis without resorting to invasive biopsies, which is especially important in settings with limited healthcare resources.
Article Synopsis
- The study aimed to assess the diagnostic accuracy of ultraviolet-induced fluorescence (UVF) dermoscopy for various non-cancerous skin conditions compared to traditional polarized light dermoscopy.
- Researchers evaluated 208 patients with different dermatoses that might show UV-induced signs, applying standardized comparisons of both UVF and polarized dermoscopic findings.
- Significant UVF responses were observed in several conditions, linking specific fluorescence colors to particular skin issues, helping to improve clinical diagnosis and understanding of dermatoses.
Porokeratosis is a heterogeneous group of keratinising disorders characterised by the presence of particular microscopic structural changes, namely the presence of the cornoid lamella. This structure develops as a consequence of a defective isoprenoid pathway, critical for cholesterol synthesis. Commonly recognised variants include disseminated superficial actinic porokeratosis, disseminated superficial porokeratosis, porokeratosis of Mibelli, palmoplantar porokeratosis (including porokeratosis palmaris et plantaris disseminata and punctate porokeratosis), linear porokeratosis, verrucous porokeratosis (also known as genitogluteal porokeratosis), follicular porokeratosis and porokeratoma.

This study aims to describe the dermoscopic features of scalp LM and assess the diagnostic accuracy of dermoscopy to discriminate them from equivocal benign pigmented macules.
Methods: Consecutive cases of scalp LM and histopathology-proven benign but clinically equivocal pigmented macules (actinic keratoses, solar lentigos, seborrhoeic keratoses, and lichen planus-like keratoses) from four referral centres were included.
Article Synopsis
- This review covers pityriasis versicolor (PV), a common fungal skin infection caused by the yeast Malassezia, which leads to scaly patches on the skin.
- Diagnosis of PV mainly relies on identifying its unique clinical features, with various diagnostic techniques discussed, such as microscopy and fluorescence dermatoscopy.
- Treatment primarily involves topical antifungal agents, and patient education on hygiene is crucial to prevent recurring infections, especially in humid conditions where PV is more prevalent.
Background: Grey perifollicular circles are a dermatoscopic clue to melanoma, especially in facial skin. So far, no other adnexal clues than follicular have been investigated in this diagnosis.
Objectives: The study aimed to analyse the prevalence of hyperpigmented periadnexal microcircles (HMs) in melanoma and its common simulators at non-facial non-acral sites, analyse the relation between the presence of HM, regression and hypopigmentation, and evaluate the diagnostic accuracy of this structure in melanoma.
Fordyce spots (FS) are heterotopic sebaceous glands affecting mostly oral and genital mucosa, commonly misdiagnosed with sexually transmitted infections. In a single-center retrospective study, we aimed to assess the ultraviolet-induced fluorescencedermatoscopy (UVFD) clues of Fordyce spots and their common clinical simulants: molluscum contagiosum, penile pearly papules, human papillomavirus warts, genital lichen planus, and genital porokeratosis. Analyzed documentation included patients' medical records (1 September-30 October 2022) and photodocumentation, which included clinical images as well as polarized, non-polarized, and UVFD images.

Machine learning (ML) is a subfield of AI involving statistical models and algorithms that can progressively learn from data to predict the characteristics of new samples and perform a desired task. Although it has a significant role in the detection of skin cancer, dermatology skill lags behind radiology in terms of AI acceptance.

Material And Methods: The examination was performed in 63 patients aged 20-79, including 28 women aged 20-72 and 35 men aged 23-79, divided into two groups: Group I (study group) - 33 patients with mixed cause vertigo (on the basis of the Fitzgerald-Hallpike caloric test during the VNG examination), and Group II (reference group) - 30 healthy patients. After the ENT interview and physical examination, exclusion of pathological lesions in the external acoustic meatus and middle ear, each patient was subjected to a Fitzgerald-Hallpike caloric test during VNG examination, as well as a VHIT test and Dix-Hallpike test, with the evaluation of eyeball reaction during head rotation.
