Upon examination, a patient with adenomyosis is likely to show which characteristic of the uterus?

The characteristic of the uterus in a patient with adenomyosis is typically described as having a globular and boggy texture. Adenomyosis occurs when the endometrial tissue, which normally lines the uterus, grows into the muscular wall of the uterus, causing it to become enlarged and distorted.

As this condition progresses, the affected uterine wall becomes thickened and may feel softer or boggy upon palpation due to the presence of endometrial tissue within the myometrium. The "globular" aspect refers to the rounded shape and enlargement of the uterus, which is a common finding in adenomyosis.

In contrast, other options do not accurately represent the physical traits of the uterus in this condition. A normal-sized uterus would not suggest adenomyosis, as the condition typically results in enlargement. A firm consistency is more characteristic of a healthy uterus, and a smaller than normal size would be inconsistent with the proliferation of tissue associated with adenomyosis. Thus, the description of the uterus as globular and boggy is aligned with the clinical presentation of patients suffering from adenomyosis.
