ABSTRACT: Accessory breast tissue development frequently
occurs in addition to physiologic breast development and is a common congenital
condition with an occurrence of 0.4% to 6% in women and 1% - 3% in men. A 31-year-old G1P0 female presented to our
triage at 20 + 4 weeks gestation with a one-week history of painful
bilateral axillary lumps. Her last menstrual period was consistent with an
estimated gestational age of 39 + 3 weeks by LMP. She had emigrated from Bengal
three years earlier with no other gynecological complaints and knew of no
abnormalities on physical exam. The painful axillary lumps were found to be
accessory breast tissue. This entity is presented as a palpable thickening that is most prevalent along the milk line in
the region immediately below the breasts, along the abdomen, in the axilla and in the groin region adjacent to the vulva. Affected individuals may undergo
premenstrual changes such as tenderness, swelling, and difficulty with shoulder range of motion and irritation. The onset of
pregnancy stimulates the tissue and makes it more evident as it did with our
patient.
