A hard-to-reach bleeding lesion

The history and exam were all suspicious for basal cell carcinoma (BCC), the most common of all cancers in the United States. (In African Americans, the most common skin cancer is squamous cell carcinoma). The suspicious lesion in this case was in a crevice, making it difficult to obtain a shave or punch biopsy.

As a result, a 4-mm disposable sterile curette was used (Figure). After informed consent was obtained, the lesion was cleansed with alcohol and marked with a surgical marker. Then, buffered lidocaine 1% with epinephrine was injected with a small syringe. Using a firm scraping motion with gentle rotation, a 4-mm sample of the lesion was quickly obtained and placed in standard formalin. Hemostasis was immediately obtained with firm application of 70% aluminum chloride in water using a cotton-tipped applicator. Heavy petrolatum was applied as a dressing.

The patient was confirmed to have a BCC and underwent Mohs surgery with clear margins after 1 stage. This case demonstrates the utility of a curette as a biopsy instrument for patients presenting with suspicious lesions in hard-to-reach places.
