| Paget's disease of the breast | |
|---|---|
| Diagnosis in short | |
 Paget's disease. H&E stain. | |
|
| |
| LM | large epithelioid cells - nested or single - in the epidermis, clear/pale cytoplasm (occasionally eosinophilic), large nucleoli |
| LM DDx | benign Toker cell hyperplasia, malignant melanoma, Bowen's disease, apocrine carcinoma of the skin |
| IHC | CK7 +ve, CEA +ve, S-100 -ve, CK5/6 -ve, HER2 +ve |
| Gross | erythema, +/-weeping, +/-crusted |
| Site | breast |
|
| |
| Prognosis | usu. associated with invasive breast carcinoma |
| Clin. DDx | nipple adenoma, contact dermatitis |
Paget's disease of the breast, also Paget disease of the breast and Paget's disease of the nipple, is a lesion of the breast. It is abbreviated PDB.[1]
There is also a Paget's disease of the bone - just to make things confusing. This is dealt with in its own article and has nothing (from a pathologic perspective) to do with the Paget's disease discussed in this article; these two things just happened to be discovered by the same guy.
Non-bone Paget's disease is subdivided into:
- Mammary Paget's disease - dealt with in this article.
- Extramammary Paget's disease.
Histologically, i.e. under the microscope, the above are essentially identically; however, the associations (and prognosis) are quite different!
General
- Cells in the epithelium, i.e. skin, that look like they don't belong.
- Associated with underlying invasive breast carcinoma.[2]
Note:
- Extramammary Paget's disease is not usually associated with malignancy.
Gross
Features:[3]
- Erythematous, i.e. red.
- +/-Crusted.
- +/-Weeping (wet).
DDx - clinical:
Images:
Microscopic
Features:[2]
- Epitheliod morphology (round/ovoid).
- Cells nested or single.
- Clear/pale cytoplasm key feature - may also be eosinophilic.
- Large nucleoli.
Note:
- The neoplastic cells of Paget's disease may contain melanin.[7]
DDx
- Benign Toker cell hyperplasia.
- Malignant melanoma.
- Bowen disease.
- Nipple (duct) adenoma (clinical DDx).
- Apocrine carcinoma of the skin.[8]
Images
Paget disease - low mag. (WC/Nephron)
Paget disease - high mag. (WC/Nephron)
www:
- Paget disease of the breast - several good pictures (upmc.edu).
- Paget disease of the nipple (webpathology.com).
IHC
Panel:[2]
- S-100 -ve, HMB-45 -ve (both typically +ve in melanoma).
- CK7 +ve. (???)
- Toker cells CK7 +ve.[9]
- CEA +ve (-ve in Bowen's disease, -ve in Toker cells).
