    Temporal Triangular Alopecia: Significance of Trichoscopy in Differential Diagnosis
    (2015) Kose, O. Karadag; Gulec, A. T.; 0000-0002-4355-958X; 25187354; R-8431-2019
    BackgroundThere are only two case reports in literature regarding the trichoscopic features of temporal triangular alopecia (TTA). Differential diagnosis of other types of localized alopecia such as alopecia areata is necessary in some cases. ObjectiveTo evaluate the potential benefit of trichoscopy in the clinical diagnosis of TTA. MethodsNine patients with a clinical diagnosis of TTA were included in the study. Trichoscopic examination was performed by a polarized-light handheld dermatoscope with a 10-fold magnification. The images were obtained by a digital camera that produced imagery with a 3-fold optical zoom. ResultsShort vellus hairs, vellus hair length diversity and white hairs were encountered in all subjects, while white dots, honeycomb pigment pattern, arborising red lines and epidermal scale were noted in 22%-33% of them. None of the cases showed trichoscopic features such as tapering hairs, yellow dots or loss of follicular openings. ConclusionWe suggest that it seems possible to differentiate TTA by a handheld dermatoscope. Short vellus hairs with length diversity and white hairs in the absence of diagnostic features of other types of localized alopecia should be considered in favour of TTA.

    Tzanck Smear as An Accurate and Rapid Diagnostic Tool for Cutaneous Alternariosis in A Renal Transplant Recipient
    (2016) Togral, A. Karatas; Gulec, A. T.; 27663148
    Alternaria species are becoming increasingly important opportunistic pathogens in recipients of solid organ transplant, as it has been shown that dissemination with systemic involvement is not as rare as previously reported. Therefore, rapid and accurate diagnosis is necessary for appropriate patient management. We report a patient with renal transplant who developed recurrent cutaneous alternariosis. Tzanck smear successfully and very rapidly revealed hyphae and spores in both the primary and subsequent lesions. Furthermore, Tzanck smear provided guidance for histopathological examination of the second lesion, which failed to disclose the fungal elements until additional deeper serial sections were performed. The present case emphasizes that the Tzanck smear is a useful clinical tool leading to the immediate correct diagnosis even in deep fungal infections.
