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 [1]. PDB constitutes only about 1-4% of reported cases of breast cancer in females [2]. About 40% of those associated with invasive cancer are associated with ductal carcinoma in situ [3]. 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 [1]. PDB often presents as unilateral disease. It can occur in accessory nipples, as well as non-breast tissue after mastectomy [4] [5]. Furthermore, it has been reported to occur in the breast tissue in the axilla [6].

PDB affects the skin and causes lesions that may resemble eczema [7]. 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.

• Nipple Discharge

  Nipple discharge: About 50% of papillary carcinomas occur beneath the nipple, resulting in bloody nipple discharge. 7 Answers A The only way to determine if a lump is cancerous or benign is through a medical examination. [sharecare.com]

  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]

  During a biopsy, your doctor obtains a small sample of tissue from the skin of your nipple for examination under a microscope. If you have nipple discharge, a sample of the discharge might also be collected for microscopic examination. [web.archive.org]

• Ulcer of Nipple

  […] an ulcer 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]

  which may later progress to ulceration, erosion and frank destruction, bloody nipple discharge, nipple retraction, or a palpable mass. [indianjcancer.com]

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 [8].

Imaging studies include mammography, ultrasound and magnetic resonance imaging (MRI) [1]. These are useful in detecting nonpalpable breast masses [9]. 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 [10].

These studies are designed to find new treatments and better ways to use current treatments. As new and improved treatments are found for breast cancer, the treatment options for Paget disease of the nipple will also improve ( 2, 5 ). [web.archive.org]

As you have alluded to, Paget's disease of bone (osteitis deformans) is a disease of uncertain etiology, which is characterized by excessive bone resorption accompanied by abnormal new bone formation. [oncolink.org]

Etiology The disease is caused by a mutation in the gene encoding 3-beta-hydroxy-delta-5-C27 steroid oxidoreductase (HSD3B7, 16p12-p11.2). Transmission is autosomal recessive. [orpha.net]

Furthermore, the breast examination reveals no untoward findings (such as a palpable mass, axillary lymphadenopathy, or nipple discharge), making a benign etiology even more likely. [prognosisapp.com]
