Abstract
We report 2 cases of basal cell carcinoma with difficulty in clinical diagnosis. Case 1: A 71-year-old female noticed a brownish erythema on her right leg 3 months ago. The lesion was 16×14mm in diameter with crusts and scales. Case 2: A 63-year-old male noticed a brownish erythema on his right leg 3 years ago. The lesion was 15×15mm in diameter with crusts and scales. Dermoscopy showed no pigment network in both cases. Leaf-like areas, multiple blue-gray dots/globules, small ulcers, arborizing vessels in case 1 and multiple blue-gray dots/globules, small ulcers, arborizing vessels in case2 suggested these tumors are basal cell carcinoma. Histologically, the tumors in both cases showed typical features of superficial basal cell carcinoma. We were very impressed that dermoscopy was such a useful tool for the diagnosis of basal cell carcinoma. [Skin Cancer (Japan) 2006; 21: 336-339]
