Which Tanner stage indicates the presence of a secondary mound in the areola?

The Tanner stages are a system used to assess the development of secondary sexual characteristics during puberty. Tanner Stage IV is specifically characterized by the development of a secondary mound of areolar tissue as the breast tissue matures. In this stage, the areola becomes raised and forms a distinct mound over the breast tissue, indicating that significant breast development has occurred.

Understanding the progression through Tanner stages is important for healthcare professionals to monitor normal growth and development in adolescents. During Tanner Stage II, there is some breast development, but it is not yet defined by a secondary mound. Tanner Stage III presents more pronounced breast tissue development, but again, it lacks the distinct secondary mound seen in Tanner Stage IV. Tanner Stage V represents full maturity of breast development, where the breast contour is more rounded and the areola is no longer elevated into a mound.

In summary, Tanner Stage IV is the stage that clearly indicates the presence of a secondary mound in the areola, making it the correct answer to the question.
