Dermoscopy And 30% Potassium Hydroxide Direct Examination As Diagnostic Tools For Distal Lateral Subungual Onychomycosis, Evangelina Lumban Gaol, Eliza Miranda, Sondang Pandjaitan Sirait

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Culture and histopathological examination are gold standards for diagnosing onychomycosis. However, these examinations are subject to several limitations. Dermoscopy has the potential to become a promising diagnostic tool for onychomycosis. Direct examination of potassium hydroxide (KOH) also has advantages similar to dermoscopy. Knowing the accuracy of both examinations can help clinical decision-making. Our objectives are to assess the diagnostic value of dermoscopy, KOH examination, and their combination for distal lateral subungual onychomycosis compared to culture or histopathology.

Methods: This was a cross-sectional diagnostic study of nails with suspected distal lateral subungual onychomycosis. Sixty nails were included in this study. …

Dermoscopic And Histopathologic Findings In Diagnosing Postpartum Pemphigoid Gestationis, Rudi Chandra, Irma Damayanti Roesyanto-Mahadi

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Pemphigoid gestationis (PG) is an uncommon autoimmune vesiculobullous skin disorder associated with pregnancy, that occurs during mid-to-late pregnancy and immediate postpartum period. The diagnosis of PG is based on histopathology and direct immunofluorescence. Dermoscopy is a non-invasive diagnostic tool that provides a connection between macroscopic clinical dermatology and microscopic dermatopathology.

Case Illustration: We reported a case of a 22-year-old primigravida woman with postpartum PG. This PG case was diagnosed clinically, dermoscopically, and histopathologically.

Discussion: Since PG is thought to be a variation of the bullous pemphigoid (BP), the two resemble each other clinically and immunologically. The well-defined structures with …

Presentations Of Cutaneous Disease In Various Skin Pigmentations: Porokeratosis, Henry Lim, Christopher M. Wong, Christian J. Scheufele, Daniel A. Nguyen, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Porokeratosis was first described in 1893. It is a relatively rare disorder with over 9 subtypes. Lesions are clinically characterized as well-demarcated, erythematous papules (raised, <1 cm) or plaques (raised, >1 cm), with an atrophic center, and raised scaly border. Porokeratosis is an important diagnosis to identify because it may undergo malignant transformation and mimics many commonly encountered diagnoses. These commonly mimicked diagnoses include squamous cell carcinoma, tinea corporis, nummular dermatitis, and psoriasis vulgaris, to name a few. The clinical images in this review focus on identifying porokeratosis along the full spectrum of skin tones.

The Role Of Dermoscopy In Non-Pigmented Skin Disorders, Hafiza Fathan, Wresti Indriatmi, Rahadi Rihatmadja, Inge Ade Krisanti

Journal of General - Procedural Dermatology and Venereology Indonesia

The use of dermoscopy in non-pigmented skin disorders includes dermoscopy as a diagnostic tool for non- pigmented skin tumors, inflammatory diseases (inflammoscopy) and/or infectious disease (entomodermoscopy), lesions on nail fold and as a tool to monitor skin reaction as a response to treatment and/or side effect. The diagnosis becomes easier, faster and less expensive with dermoscopy without the need for invasive procedures. Knowledge on vascular pattern and its architectural arrangement; which is coupled with additional dermoscopic features, can aid clinicians to the diagnosis. Dermatoscopy can also predict, monitor and evaluate therapeutical response and/or side effect of skin disorders. Nonetheless, dermoscopy …
