multiple choice

Explanation:

Analyze the question stem

The question asks for the most common noncancerous (benign) neoplasms. A neoplasm is an abnormal growth of tissue.

Evaluate the options

• callus: A callus is a thickened area of skin caused by repeated friction or pressure, not a true neoplasm.
• keratosis: Keratosis (such as seborrheic keratosis) refers to a benign, noncancerous growth of keratinocytes. It is one of the most common noncancerous skin neoplasms.
• basil cell carcinoma: This is a misspelling of basal cell carcinoma, which is a malignant (cancerous) skin tumor, not a noncancerous one.
• alopecia areata: Using the Alopecia Terminology knowledge point, we know this is an autoimmune condition causing patchy hair loss, not a neoplasm.
