Background: Dermoscopy is a non-invasive diagnostic technique that provides an added advantage to the routine clinical diagnostic exercise. Role of dermoscopy in cutaneous small vessel vasculitis has not been explored well. Objective: This study was intended to delineate the dermoscopic features of cutaneous small vessel vasculitis and to correlate them with histopathological findings of the disease. Materials and Methods: This was a cross-sectional study involving 30 patients with cutaneous small vessel vasculitis confirmed by histopathology and direct immunofluorescence. In each patient, dermoscopic features of early/evolving and established lesions were recorded. Dermoscopic-histopathological correlation was assessed for established lesions. Results: On dermoscopy, the early/evolving lesions showed a dull red background in all the 30 (100%) patients, red globules in 8 (26.7%), and red dots in 4 (13.30%) patients. The established lesions showed red background in 28 (93.3%) patients, white and yellow structureless areas in 19 (63.33%) patients each, red globules in 18 (60%), and red dots in 16 (53.3%) patients. A statistically significant association between red globules and red blood cell extravasation was noted (P-0.01). White and yellow structureless areas also showed a statistically significant association between sparse (P-0.023) and dense (P-0.007) perivascular infiltrates, respectively. Conclusion: Dermoscopy of cutaneous small vessel vasculitis exhibits fairly reliable and reproducible features correlating well with histopathological aspects of the disease. Hence, inclusion of dermoscopy in the clinical diagnostic protocol for cutaneous small vessel vasculitis is beneficial in complementing the clinical diagnosis and in differentiating from other inflammatory purpuras. |
