Which type of breast lesion is characterized by a glandular tumor?

• A. Fibroadenoma
• B. Fat necrosis
• C. Abscess
• D. Duct ectasia

Answer: (A)

A fibroadenoma is characterized as a benign glandular tumor of the breast. This type of lesion is composed of both glandular tissue and stromal (connective) tissue, which gives it a distinct structure that is typically well-defined on imaging studies. Fibroadenomas are most common in younger women, often presenting as a painless lump that is mobile and firm to the touch.

The nature of a fibroadenoma allows it to be categorized as a glandular tumor, as it arises from the tissues that make up the ducts and lobules of the breast. Its benign nature, while important for treatment considerations, is a hallmark that sets it apart from other types of breast lesions.

Other types of lesions, like fat necrosis, abscess, and duct ectasia, do not primarily stem from glandular tissue and can have different underlying causes and treatments. Fat necrosis often results from trauma to the breast, abscesses are usually infections leading to pus formation, and duct ectasia involves the dilation and potential obstruction of milk ducts but does not represent a true glandular tumor. Thus, the classification and characteristics of a fibroadenoma distinctly align with the question’s focus on glandular tumors.
