The Areola: Characteristics and Related Conditions
Also known as: areolar conditions, nipple and areola changes
Anatomy and normal variations
The areola is the circular pigmented area surrounding the nipple, present in both women and men. Its color ranges from pale pink to dark brown depending on skin tone, age, and hormonal changes. In adult women, the areola is round with a varying size, on average about 1 to 2.5 inches (3 to 6 cm) across. Conditions affecting the areola are a common reason for dermatology and breast health visits in the United States, especially during pregnancy or when a suspicious finding needs further evaluation.
Causes and risk factors
Changes affecting the areola can be hormonal, infectious, inflammatory, or tumor-related in origin. Main risk factors include:
- Hormonal changes: pregnancy, breastfeeding, menopause, oral contraceptives, hyperprolactinemia
- Skin conditions: eczema, psoriasis, Paget disease of the breast (a rare form of breast cancer affecting the nipple and areola)
- Infections: subareolar abscess, mastitis, yeast infections
- Genetic factors: breast cancer predisposition, family history
- Smoking: a contributing factor to recurring periareolar infections
Symptoms
Clinical signs affecting the areola, in rough order of frequency:
- Changes in pigmentation: lightening or darkening, asymmetric patches
- Itching and localized irritation, often from eczema
- Scaling or skin thickening, which can suggest psoriasis or Paget disease
- Pain and tenderness, especially before a period or while breastfeeding
- Nipple discharge: clear, milky, bloody, or pus-like
- Ulceration or a persistent scab, a warning sign that should always raise concern for a tumor
- Retraction of the nipple or distortion of the areola
Diagnosis
The doctor asks about personal and family history, then performs a thorough clinical exam of the areola and breast. If there is any concern, a breast ultrasound or mammogram is ordered. Cytology of any discharge may be performed. When a suspicious lesion is present, a skin biopsy is essential to rule out Paget disease or carcinoma. Hormone testing rounds out the workup if an endocrine disorder is suspected.
Treatments
Treatment depends on the underlying cause:
- Eczema: appropriate-strength topical corticosteroids, emollients, and identifying and avoiding triggering allergens
- Bacterial infections: oral antibiotics (such as amoxicillin-clavulanate or a macrolide); surgical drainage for an established abscess
- Yeast infections: topical antifungals (miconazole, clotrimazole) on the areola and nipple
- Hormonal causes: correcting the underlying hormonal imbalance and adjusting contraception if needed
- Cancer: surgery for confirmed Paget disease or carcinoma, often combined with radiation therapy
- Symptom relief: topical pain relief and gentle skin care without harsh soaps
Prevention
Several measures can help reduce the risk of areolar conditions:
- Practice gentle hygiene: cleanse with lukewarm water and no harsh soap, and dry carefully after breastfeeding
- Avoid smoking, a contributing factor to recurring periareolar infections
- Know how your breasts normally look and feel, and report any change in the skin, color, or shape of the areola to a doctor right away
- See a doctor for any unusual change that lasts more than two weeks
- Follow recommended screening guidelines: the U.S. Preventive Services Task Force (USPSTF) recommends a mammogram every two years for women ages 40 to 74
- Protect areolar skin from the sun with appropriate sunscreen when it is exposed
When should you see a doctor?
See a doctor promptly for persistent ulceration or scabbing, unexplained bloody discharge, sudden retraction of the nipple, or an associated palpable lump. Any asymmetric change in areolar pigmentation, itching that does not respond to topical treatment, or a sore that will not heal should prompt a visit without delay.
