Paget's disease of the breast is a form of cancer that primarily affects the skin of the nipple and sometimes the areola as well. It is a rare ailment that was first described in 1874 by Sir James Paget. Many cases of Paget's disease are associated with an underlying breast carcinoma.
Paget's disease of the breast (PDB) is a carcinoma of the breast that involves the nipple and the areola. It is a rare disease and is usually linked to carcinoma in situ, or an invasive carcinoma in the breast, which may be evidenced by a palpable mass on examination of the breast . PDB constitutes only about 1-4% of reported cases of breast cancer in females . About 40% of those associated with invasive cancer are associated with ductal carcinoma in situ . PDB can occur in both men and women, however, it predominantly affects the latter. The disease is often diagnosed in the 5th decade, although cases of younger and older-onset have been reported . PDB often presents as unilateral disease. It can occur in accessory nipples, as well as non-breast tissue after mastectomy  . Furthermore, it has been reported to occur in the breast tissue in the axilla .
PDB affects the skin and causes lesions that may resemble eczema . For this reason, it may be misdiagnosed as a dermatological condition. The nipple and areola are often erythematous, itchy, flaky, and sometimes there is an erosion of the nipple. A nipple discharge is not uncommon and may range from serosanguineous to purulent. Other reported findings are ulceration, bleeding, thick plaque formation, and pain that is often burning in nature.

Abstract Paget's disease of the breast nipple and areola complex represents a cutaneous manifestation of an underlying breast malignancy. [ncbi.nlm.nih.gov]
There are several clinical cutaneous manifestations of psoriasis but most commonly the disease presents as chronic, symmetrical, erythematous, scaling papules and plaques. [farethrea.duckdns.org]

The other theory suggests that skin cells of the nipple spontaneously become Paget cells. [web.archive.org]
Your doctor will do a physical exam and should suggest having a mammogram of both breasts done immediately. [truthorfiction.com]
The areola lesion was highly suggestive of a dermatologic malignancy such as malignant melanoma. As such, a biopsy was performed with initial findings suggestive of cutaneous melanoma. [ncbi.nlm.nih.gov]
Prolonged stress may lead to frustration, anger, hopelessness, and -- at times -- depression. The person with the illness is not the only one affected. Family members are also influenced by the health changes of a loved one. [web.archive.org]
You may have many different emotions, including anger, resentment, guilt, anxiety and fear. These are all normal reactions and are part of the process many people go through in trying to come to terms with their condition. [macmillan.org.uk]
Paget Disease of the Breast Nipple Discharge Breast discharge is the spontaneous flow of fluid from the nipple at any time other than during nursing. [medicinenet.com]
The symptoms include: Itching, tingling, redness, and/or a burning sensation in the affected nipple Sensitivity and pain Flaking of scales and skin thickening of the affected nipple Flattening or turning inwards (inversion) of the nipple Discharge (yellowish [news-medical.net]
The most common presenting symptoms were nipple discharge and eczematous changes of the nipple/areola complex. Ninety-seven patients (93.2%) had an underlying invasive or noninvasive cancer associated with Paget's disease. [ncbi.nlm.nih.gov]
If you have nipple discharge, a sample of the discharge might also be collected for microscopic examination. If cancer cells are detected in the samples collected, you may be referred to a breast surgeon to discuss treatment options. [web.archive.org]
Ulcer of Nipple
[…] the nipple might flatten out or turn inwards (invert) there may be a discharge or bleeding from the nipple the area might feel itchy or sore there may be a lump in the same breast. [breast-cancer.canceraustralia.gov.au]
Paget's disease of the breast has four stages, stage zero describing malignancy that only involves the epidermis, and stage four being PDB that is associated with invasive ductal carcinoma. There are several modalities that are used in the diagnosis of PDB. Clinical breast examination is of particular importance as up to 50% of those with PDB will have a palpable breast lump. Subsequent diagnostic techniques involve both invasive and noninvasive strategies.
Breast tissue from the affected area should be analyzed histologically, thus necessitating a biopsy. The choice of what type of biopsy to carry out ranges between wedge, punch, shave and surface biopsy. Immunochemistry is also carried out on biopsy samples. Together, the above laboratory techniques (immunohistochemistry) form the definitive diagnostic measure for PDB .
Imaging studies include mammography, ultrasound and magnetic resonance imaging (MRI) . These are useful in detecting nonpalpable breast masses . On mammography, PDB may cause distortion of the breast architecture, calcifications, edema, and nipple changes. Negative findings on mammography do not rule out the possibility of PDB, as about 70% of cases with histological evidence of the disease also have positive findings on mammography. Therefore there is a proportion of cases of PDB without mammographic features of the disease. MRI is useful in detecting PDB that otherwise goes undetected by the former .
In some instances, women who show signs of Paget's disease of the nipple will also have an abnormal mammogram or present a breast lump upon physical examination. [imaginis.com]
Radiation without Surgery The possibility of radiation treatment alone for patients with Paget's disease without a palpable mass or abnormal mammogram has been reported. [aboutcancer.com]
