![]() In-Service Exam Breast Reduction - 2003 A 16-year-old girl has had rapid, asymmetric enlargement of the left breast over the past year. On physical examination, an 18-cm mass can be palpated; there is ptosis and stretching of the nipple-areola complex. The veins are prominent and dilated, and there is ulceration of the skin superolateral to the nipple. Mammography shows a dense, circumscribed, homogeneous mass that encompasses the entire breast. Which of the following is the most appropriate management? (A) Hormone therapy
This 16-year-old girl
has fibroadenoma, which is the most common neoplasm of the breast in adolescents.
Giant fibroadenomas are typically solitary, firm, nontender, benign lesions
that develop at or soon after the onset of puberty. They are larger than
5 cm in diameter and double in size within a short time. Rapid enlargement
of one breast is characteristic. Prominent veins are noted over the arc
of the tumor; some patients develop skin ulcerations because of the pressure
caused by the fibroadenoma. Enucleation is curative, and the risk for
local recurrence is minimal. Mastectomy is excessive and unnecessary in patients with giant fibroadenoma. Reduction mammaplasty is indicated for management of juvenile breast hypertrophy, which is characterized by diffuse enlargement of the breast without a palpable mass or nodes.
Sensation to the nipple-areola complex is provided primarily by which of the following nerves? (A) Anterior cutaneous
nerve from T3
Sensation to the nipple-areola complex is primarily provided by the lateral cutaneous nerve from T4. The innervation of the skin of the breast is segmental and is derived from the dermatomes associated with breast development. Knowledge of this innervation is crucial before performing breast surgery. The upper breast receives its sensation from the supraclavicular nerves that originate from the third and fourth branches of the cervical plexus. The medial and inferior aspects of the breast are innervated by small medial branches of the anterior cutaneous nerves. The lateral cutaneous branches course subcutaneously to provide sensation to the midclavicular region and contribute to the innervation of the areola.
A 40-year-old woman has cyanosis of the right nipple one hour after undergoing bilateral breast reduction with removal of 1500 g of tissue on each side. Which of the following is the most appropriate management? (A) Observation
The findings seen in this patient are consistent with necrosis of the nipple-areola complex. This condition can be caused by direct devascularization of the breast mound, torsion, or direct pressure on the nipple and areola. Appropriate management includes immediate decompression with release of the sutures and operative exploration. Excision of the nipple-areola complex with subsequent defatting and conversion to a full-thickness skin graft is indicated for those patients who have ischemia of the breast mound identified on operative exploration. Free nipple grafting may be considered to decrease the risk for necrosis of the nipple-areola complex in women undergoing breast reduction with an estimated volume of resection of more than 1500 g on each side, a nipple transposition length of 25 cm or greater, or associated risk factors such as smoking or diabetes mellitus. Although leeches can be used to relieve venous insufficiency, this process would need to be undertaken over several days to be effective. Hyperbaric oxygen therapy increases the oxygen content of the tissue but is also a lengthy process. References Gynecomastia is an adverse effect of administration of each of the following agents EXCEPT (A) cimetidine (Tagamet)
Many agents have been linked to gynecomastia, such as amphetamines, cimetidine, digitalis, haloperidol, isoniazid, methyldopa, opiates, progestins, spironolactone, and tricyclic antidepressants. Associated conditions include obesity, liver disease, kidney failure, adrenal tumors, hyperthyroidism, and hypothyroidism. Gynecomastia can also be caused by increased estrogen levels (men with testicular tumors or who use androgen-based agents) or decreased estrogen levels (men with Klinefelter syndrome or who undergo orchiectomy). Zolpidem has not been shown to be a cause of gynecomastia.
