Question

A 35-year-old woman, a chronic smoker, presents with recurrent painful periareolar swelling and purulent nipple discharge for the past 6 months. She has undergone incision and drainage twice, but the symptoms recur after a short period. Which of the following statements about the most likely diagnosis is true?

• A. Recurrent retroareolar abscesses
• B. Cord-like swelling on the side of the breast
• C. Recurrent costochondral pain
• D. Bloody nipple discharge

Hint:

Smoking cessation is the single most critical lifestyle modification for patients with periductal mastitis. Remember that simple I&D is never curative for this condition; definitive management requires total duct excision (Hadfield's procedure).

Answer 1

The Correct Option is A

Concept:
A young female patient with a history of chronic smoking presents with a highly characteristic clinical picture of recurrent periareolar swelling and purulent discharge despite multiple previous surgical incision and drainage (I&D) procedures.
The clinical task is to identify this specific benign breast disease, understand its strong association with smoking, and recognize its tendency for frustrating recurrence without definitive ductal surgery.
Explanation:
• The clinical scenario perfectly describes Zuska's disease, also medically known as periductal mastitis or recurrent subareolar/retroareolar abscess.

• There is an extremely strong, well-documented epidemiological association between cigarette smoking and the development of periductal mastitis; over $90\%$ of patients diagnosed with this condition are chronic smokers.

• Pathophysiologically, the toxic compounds in cigarette smoke induce squamous metaplasia of the normally cuboidal epithelial lining of the major lactiferous ducts behind the nipple. This metaplasia leads to the shedding of keratin, which obstructs the ducts (keratin plugs), leading to stasis, ductal dilatation, and inevitably, secondary bacterial infection, often involving mixed aerobic and anaerobic flora.

• Clinically, the condition presents as a painful, erythematous subareolar mass or frank abscess. If the abscess spontaneously ruptures or is simply surgically drained, it frequently leads to the formation of a chronic, discharging mammillary fistula at the edge of the areola.

• Simple Incision and Drainage (I&D) is notoriously associated with an extremely high recurrence rate because it only treats the acute infection but leaves the underlying diseased, plugged, and metaplastic duct in place.

• Definitive surgical treatment requires a total central duct excision (Hadfield's operation) after the acute inflammatory phase has resolved with antibiotics, coupled with absolute, strict smoking cessation by the patient.

• Option B describes Mondor's disease (superficial thrombophlebitis). Option C describes Tietze syndrome. Option D describes Intraductal papilloma.
Final Answer:
The most likely diagnosis is Zuska's disease, which accurately features recurrent retroareolar abscesses due to underlying ductal squamous metaplasia.
