It is a special type of carcinoma of the breast with low malignancy and slow progression. The primary lesion is located in the large ducts of the nipple area, gradually infiltrating into the deep layers of the epidermis of the nipple and areola.

1. At the onset of the disease, the nipple may itch or feel intensely itchy, accompanied by burning pain. Subsequently, the skin of the nipple and areola becomes red, with yellowish-brown scaly crusts. Removing the crusts reveals grade I skin erosion, presenting as chronic eczema-like changes.
2. The affected skin becomes hardened with clearly defined borders. As the condition progresses, the nipple may exhibit inward invasion and damage, and a mass may be palpable deep within the areola.
3. Lymphatic metastasis occurs relatively late.
4. For cases where diagnosis is difficult, a biopsy may be performed.
