Answer :

Answer:Perform a thorough physical examination of the lesion, noting its size, shape, color, and any other distinguishing characteristics.

Dermatoscopic examination to look for specific features of BCC.

Biopsy of the lesion for histopathological examination to confirm the diagnosis.

Other potential differential diagnoses to consider could include:

Squamous cell carcinoma (SCC): Another type of skin cancer that can present similarly but usually has a different growth pattern and may have a more scaly or keratotic surface.

Actinic keratosis: A precancerous lesion that can evolve into SCC and may present as a crusting or scaling lesion.

Seborrheic keratosis: A benign skin growth that can sometimes mimic the appearance of BCC but usually has a more waxy, stuck-on appearance.
