“…The brown dots and globules are due to dried serum, necrotic keratinocytes and melanin retention. Scaling is due to hyperkeratosis [8,9]. The white linear folds / 'crumpled fabric' appearance were due to folding of superficial keratinocytes (roof) due to flaccidity was observed in late lesions of HZ.…”

“…Dermoscopy is a rapid, non-invasive tool which helps to visualize surface and sub surface features that are not visible to naked eyes [6]. Dermoscopy of BBD is explained in a single case report till date [7] and limited descriptions on dermoscopic patterns in HZ are present in the literature [8,9,10]. Furthermore, there is a hiatus in the dermoscopic distinction between the two.…”

Introduction: Blister beetle dermatitis (BBD) and herpes zoster (HZ) manifest suddenly with vesicular lesions mimicking each other and progress rapidly. But a lack of definite differentiating criteria yearns the need for better investigating modality. Though histopathology persuades the need, is an invasive procedure, commonly deferred. Thus, dermoscopy a non-invasive rapid diagnostic tool, can help in differentiating. Objectives: To evaluate different dermoscopic patterns of BBD and HZ to differentiate both and to study dermoscopic features in early and late stages of lesions. Methods: An observational cross-section study conducted in southern India. Nine patients with clinical features suggestive of BBD and HZ were recruited. Lesions were divided arbitrarily into early and late. Dermoscopic examination was performed with handheld dermoscope. Diagnosis was confirmed by skin biopsy and Tzanck smear wherever necessary. Statistical analysis performed using data in terms of frequencies and percentages. Results: Dermoscopy of early BBD lesions showed multiple discrete and confluent yellowish-white structures, brown dots, roundish white globules, gray structures, ‘targetoid pattern’, brown areas over intense reddish pink background. Late BBD lesions revealed pinkish-white area, reduced gray structures and, dotted and globular vessels. Early HZ lesions showed polylobular gray and brown globules, bright pink background, gray globules covered by grayish veil-like structure with gray rim. Late HZ lesions revealed ‘solar eclipse’ pattern and ‘crumpled fabric ‘patterns. The dermoscopic findings correlated with histopathology. Conclusions: Dermoscopic patterns show peculiar features consistently pertaining to BBD and HZ thus help in early diagnosis assisting in accurate treatment both conditions.

Background Leprosy is known to be a great mimicker. Its dermatoscopic evaluation may be of value in establishing diagnosis. Objective To study the dermatoscopic findings encountered across the leprosy spectrum. Methods This was a multi-centre cross-sectional study of leprosy patients, where after a thorough cutaneous and neurological evaluation, representative skin lesions from the study patients were photographed in standard settings, and the most representative skin lesions were chosen for dermatoscopic evaluation. Data was entered in a structured proforma and a descriptive analysis of dermatoscopic patterns was carried out. Results A total of 53 cases of ages between 14 and 80 years, ranging from tuberculoid to the lepromatous spectrum of disease, with active skin lesions in the form of patches and plaques were included. The spectrum of leprosy as per Ridley-Jopling classification at diagnosis was indeterminate in 1 (1.9%), tuberculoid in 1 (1.9%), borderline tuberculoid in 25 (21.5%), borderline lepromatous in 9 (17%), lepromatous in 14 (26.4%) and histoid in 3 (5.7%). Dermatoscopic features included distorted pigment network in 48 (90.6%), focal white areas in 40 (75.5%), reduced eccrine and follicular openings in 43 (81.1%), widened skin lines in 28 (52.8%), circle hairs in 15 (28.3%) and white shiny streaks in 17 (32.1%). Conclusion Dermatoscopy is a practical, non-invasive device to assess skin lesions of leprosy and provide cues to its diagnosis, spectral classification and differentiating it from other granulomatous disorders. However, dermatoscopy alone cannot reliably differentiate between the various types of leprosy and future large-scale studies are required. Limitations of the study The numbers for each subtype were variable and few in some spectrum of leprosy patients. A dermatoscopic-histologic correlation was not done.
