    (2018) Moscarella, Elvira; Piana, Simonetta; Specchio, Francesca; Kyrgidis, Athanassios; Nazzaro, Gianluca; Eliceche, Maite L.; Savoia, Francesco; Bugatti, Leonardo; Filosa, Giorgio; Zalaudek, Iris; Scarfi, Federica; Inskip, Mike; Rosendahl, Cliff; Pyne, John H.; Siggs, Graeme; Cabo, Horatio; Drlik, Lubomir; Lallas, Aimilios; Longo, Caterina; Argenziano, Giuseppe; 29569417
    Background/Objectives Little is known about the dermoscopic features of atypical fibroxanthoma. Methods Results This was a case-control study. Atypical fibroxanthoma lesions were compared with a control group with non-melanoma skin cancer. Altogether 40 atypical fibroxanthoma were collected. Most developed in men (93%), appearing mainly as nodular (63%), amelanotic (93%) and ulcerated (78%) lesions. Most lesions were located on the scalp (55%) and the ears (13%). Dermoscopically, most atypical fibroxanthoma displayed red (83%) and white (70%) structureless areas and irregular linear vessels (43%). A series of features achieved statistical significance when comparing atypical fibroxanthoma with non-melanoma skin cancer. The presence of red and white structureless areas and white lines, and the absence of yellowish-white opaque scales, hairpin vessels and arborising vessels were predictive of atypical fibroxanthoma in univariate analysis. However, when squamous cell carcinoma was excluded from the analysis, none of the criteria achieved statistical significance. When basal cell carcinoma was excluded, three variables achieved statistical significance in predicting atypical fibroxanthoma: red, structureless areas, the absence of opaque yellowish-white scales and absence of white circles. Conclusions Atypical fibroxanthomas seem to be barely distinguishable from basal cell carcinoma dermoscopically, but they are more easily distinguishable from a well to moderately differentiated squamous cell carcinoma. A histopathological examination is needed for the final diagnosis.

    Strategies to improve the diagnosis and clinical treatment of dermatophyte infections
    (2023) Durdu, Murat; Ilkit, Macit; 36329574
    Introduction Significant problems are associated with the diagnosis and treatment of dermatophyte infections, which constitute the most common fungal infections of the skin. Although this is a common problem in the community, there are no adequate guidelines for the management of all forms of dermatophyte infections. Even if dermatophytes are correctly diagnosed, they sometimes exhibit poor susceptibility to several antifungal compounds. Therefore, long-term treatment may be needed, especially in immunosuppressed patients, for whom antifungal pharmacotherapy may be inconvenient owing to allergies and undesirable drug interaction-related effects. Areas covered In this review article, problems related to the diagnosis and treatment of dermatophyte infections have been discussed, and suggestions to resolve these problems have been presented. Expert opinion Pretreatment microscopic or mycological examinations should be performed for dermatophyte infections. In treatment-refractory cases, antifungal-resistant strains should be determined using antifungal susceptibility testing or via molecular methods. Natural herbal, laser, and photodynamic treatments can be used as alternative treatments in patients who cannot tolerate topical and systemic antifungal treatments.

    High accuracy of recognition of common forms of folliculitis by dermoscopy: An observational study
    (2019) Durdu, Murat; Errichetti, Enzo; Eskiocak, Ali Haydar; Ilkit, Macit; 0000-0003-1247-3932; 30914342; H-9068-2019
    Background: Clinical differentiation of folliculitis types is challenging. Dermoscopy supports the recognition of folliculitis etiology, but its diagnostic accuracy is not known. Objective: To assess the diagnostic accuracy of dermoscopy for folliculitis. Methods: This observational study included patients (N = 240) with folliculitis determined on the basis of clinical and dermoscopic assessments. A dermoscopic image of the most representative lesion was acquired for each patient. Etiology was determined on the basis of cytologic examination, culture, histologic examination, or manual hair removal (when ingrowing hair was detected) by dermatologist A. Dermoscopic images were evaluated according to predefined diagnostic criteria by dermatologist B, who was blinded to the clinical findings. Dermoscopic and definitive diagnoses were compared by dermatologist C. Results: Of the 240 folliculitis lesions examined, 90% were infections and 10% were noninfectious. Infectious folliculitis was caused by parasites (n = 71), fungi (n = 81), bacteria (n = 57), or 7 viruses (n = 7). Noninfectious folliculitis included pseudofolliculitis (n = 14), folliculitis decalvans (n = 7), and eosinophilic folliculitis (n = 3). The overall accuracy of dermoscopy was 73.7%. Dermoscopy showed good diagnostic accuracy for Demodex (88.1%), scabietic (89.7%), and dermatophytic folliculitis (100%), as well as for pseudofolliculitis (92.8%). Limitations: The diagnostic value of dermoscopy was calculated only for common folliculitis. Diagnostic reliability could not be calculated. Conclusion: Dermoscopy is a useful tool for assisting in the diagnosis of some forms of folliculitis.
