Unilateral, primarily intraductal adenocarcinoma penetrating the epidermis with eczema-like changes in the area of the nipple and areola. S.a. extramammary Paget's disease.

EtiopathogenesisThis section has been translated automatically.
It is discussed whether Paget's cells are derived from Toker cells (clear cell epithelia) which are physiologically present in the nipple and vulva epithelium.
ManifestationThis section has been translated automatically.
Mainly occurring in women after the 4th decade of life; the average age in larger studies is 54 years.
LocalizationThis section has been translated automatically.
nipple, areola and beyond. Unilateral, not symmetrical.
Clinical featuresThis section has been translated automatically.
- Slowly growing from an inconspicuous red papule or plaque, not very symptomatic (important: nipple eczema itches!), usually sharply defined, reddened and scaly (eczema-like) plaque (the most important differential diagnosis is atopic nipple eczema). Continuous surface growth leads to plaques up to 5.0-8.0 cm in diameter. It is not uncommon for them to be weeping, scaling or scaly crusts. In case of invasive growth development of nodules. Painful ulcer formation can occur with advanced findings.
HistologyThis section has been translated automatically.
In a mostly hyperplastic and parakeratotic epidermis there are single or numerous, shot-blasted, scattered, large, bright cells with large pleomorphic nuclei (Paget cells). These are CEA- and PAS-positive and also stain with low-molecular cytokeratins.

TherapyThis section has been translated automatically.
Notice!In case of chronic, therapy-resistant "nipple eczema" always remember M. Paget's nipple! After 3 months of treatment at the latest without success, histological confirmation!
