Abstract
Background: Dermoscopy is a non-invasive diagnostic procedure which allows evaluation of the features of skin lesions and reveals distinct patterns in different diseases that are diagnostically relevant. Seborrheic dermatitis is an inflammatory disorder which bears considerable clinical resemblance with other papulosquamous disorders like psoriasis. Histopathological examination of these skin lesions remains the standard diagnostic method, but it is an invasive procedure and might not always be feasible to perform.
Objective: To analyze the clinical, dermoscopic and histopathological features in seborrheic dermatitis (SD) patients presenting to our outpatient clinic and to compare and correlate the resulting dermoscopic diagnosis with the clinico-histopathological diagnosis, so as to establish the significance of dermoscopy in diagnosing this condition.
Methods: This is an observational, cross sectional study including 15 patients with classical seborrheic dermatitis lesions who attended outpatient clinic of Department of DVL over a course of 24 months and were willing to participate in the study. Patients were selected by the convenience sampling method.
Results: The predominant dermoscopic findings noted were red dots (46.66%) and linear branching vessels (53.33%) in a patchy arrangement (100%), on a dull red (60%), light red (20%) or yellow (20%) background, associated with yellow (66.66%)/white + yellow (33.33%) scales in a patchy (80%) or diffuse (20%) distribution. A positive correlation between clinico-dermoscopic and histopathological diagnoses could be made in 12 of 15 patients (80%).
Conclusion: Dermoscopy is a useful diagnostic option for identifying or conforming seborrheic dermatitis and is a good adjuvant to the clinical diagnosis.
