Challenging Diagnosis of Basal Cell Carcinoma: A Case Report Emphasizing the Clinical Utility of Dermoscopy.

Dermatological conditions often present diagnostic challenges due to their diverse manifestations and overlapping clinical features. In such cases, dermoscopy, a non-invasive imaging technique, has emerged as a valuable tool to enhance diagnostic accuracy and guide clinicians in reaching an appropriate differential diagnosis. By visualizing subsurface skin structures and microvascular patterns, dermoscopy provides additional information that complements clinical examination, aiding in the recognition of specific dermatoses and the differentiation between benign and malignant skin lesions. Herein, we present a case that demonstrates the utility of dermoscopy in distinguishing between an initial broad list of differential diagnoses, namely, basal cell carcinoma, squamous cell carcinoma in situ, and other inflammatory dermatitides, such as psoriasis and atopic dermatitis, and narrowing down the differential diagnosis to just one likely diagnosis, which was basal cell carcinoma in our case.
