    Differentiating Fordyce Spots from Their Common Simulators Using Ultraviolet-Induced Fluorescence Dermatoscopy-Retrospective Study
    (2023) Pietkiewicz, Pawel; Navarrete-Dechent, Cristian; Goldust, Mohamad; Korecka, Katarzyna; Todorovska, Verce; Errichetti, Enzo
    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. Twelve FS patients were included in the study group and fourteen patients in the control group. A novel and seemingly specific UVFD pattern of FS was described: regularly distributed bright dots over yellowish-greenish clods. Even though, in the majority of instances, the diagnosis of FS does not require more than naked eye examination, UVFD is a fast, easy-to-apply, and low-cost modality that can further increase the diagnostic confidence and rule out selected infectious and non-infectious differential diagnoses if added to conventional dermatoscopic diagnosis.

    "One blade, two cuts?" A multidisciplinary survey investigating practice variability of scalpel blade change for simultaneous excision of multiple skin lesions in the same patient
    (WILEY, 2024) Pietkiewicz, Pawel; Stefaniak, Aleksandra; Giedziun, Piotr; Calik, Jacek; Lewandowicz, Michal; Mazur, Ewelina; Cantisani, Carmen; Navarrete Dechent, Cristian Patricio; Akay, Bengue N.; Szepietowski, Jacek C.; Rosendahl, Cliff
    Background: Skin cancer incidence increases globally, requiring effective preventive measures and evidence-based treatment strategies. Current guidelines advocate for surgical excision as a first-line treatment for most early skin cancers. The study investigated practices regarding changing scalpel blades when excising multiple skin lesions in the same patient during the same visit (CSB) and explored how beliefs about iatrogenic seeding influence individual norms of practice.MethodsA multidisciplinary survey was conducted among 173 medical specialists involved in skin cancer care. Participants provided demographic information, years of experience, and practices regarding CSB in four clinical scenarios (first excised tumor: basal cell carcinoma, squamous cell carcinoma, melanoma suspect, and evident melanoma). Practice variations based on specialty, experience, and beliefs about seeding risk were statistically assessed.ResultsSurgeons exhibited a significantly higher tendency to change blades compared to non-surgeons across all diagnoses. Iatrogenic seeding (56.52%) and clinical training (18.84%) were the main reasons provided for CSB. Beliefs about seeding risk did not differ significantly between specialties.ConclusionsAlthough the practice of CSB lacks strong scientific rationale, the approach to this practice significantly varies among different medical specialties. Healthcare professionals should critically evaluate and standardize evidence-based practices to ensure optimal patient care and mitigate potential harm.

    Pityriasis Versicolor-A Narrative Review on the Diagnosis and Management
    (MDPI, 2023) Labedz, Nina; Navarrete Dechent, Cristian Patricio; Kubisiak-Rzepczyk, Honorata; Bowszyc-Dmochowska, Monika; Pogorzelska-Antkowiak, Anna; Pietkiewicz, Pawel
    This narrative review presents a comprehensive overview of the diagnosis and management of pityriasis versicolor (PV), a common superficial fungal infection caused by the yeast Malassezia. PV is characterised by scaly hypopigmented or hyperpigmented patches, primarily affecting the upper trunk, neck, and upper arms. Regarding commensal interactions, Malassezia utilises nutrient sources without affecting the human host. In cases of pathogenicity, Malassezia can directly harm the host via virulence factors or toxins, or indirectly by triggering damaging host responses. The diagnosis typically relies on recognising characteristic clinical features. Due to the wide variability in its clinical presentation, recognising the differential diagnosis is critical. In this paper, we discuss the clinical differentials, with their dermatoscopic presentation, but also describe a range of helpful diagnostic techniques (microscopy, conventional and ultraviolet-induced fluorescence dermatoscopy, and confocal microscopy). Topical therapies are the primary treatment for PV, encompassing non-specific antifungal agents like sulphur with salicylic acid, selenium sulphide 2.5%, and zinc pyrithione. Additionally, specific topical antifungal medications with either fungicidal or fungistatic properties may also be incorporated into the topical treatment regimen, such as imidazoles, allylamines, and ciclopirox olamine. Systemic therapies might occasionally be used. Patient education and the promotion of good personal hygiene are pivotal to reduce the risk of recurrence. In recurrent cases, particularly during warmer and more humid periods, prolonged prophylaxis with topical agents should be considered.
