Management of Papule on Nipple Tip

Immediate Diagnostic Steps

The National Comprehensive Cancer Network recommends examining for specific features of Paget's disease, including eczema-like appearance, erosion, ulceration, bleeding, itching, or burning sensation of the nipple-areola complex 1
The presence of a palpable breast mass or lymphadenopathy increases malignancy risk to 61.5% in patients with a papule on the nipple tip, according to the American College of Radiology 2
A full-thickness surgical biopsy of the nipple skin is the diagnostic standard and must include the full thickness of epidermis and underlying tissue, as recommended by the National Comprehensive Cancer Network 1

The American College of Radiology recommends obtaining diagnostic mammography as first-line imaging for patients with a papule on the nipple tip aged 40 years or older 3
Targeted ultrasound of the affected breast is more sensitive than mammography for detecting underlying lesions, according to the American College of Radiology 3
Breast MRI is recommended to define the extent of disease and identify additional lesions not visible on conventional imaging, with a sensitivity of 86-100% for invasive cancer, as reported by the American College of Radiology 1, 4

The National Comprehensive Cancer Network recommends breast-conserving surgery with complete excision of nipple-areola complex plus negative margin of underlying breast tissue, followed by whole-breast radiation therapy, for patients with Paget's disease without underlying breast cancer 1
Total mastectomy remains a reasonable alternative for patients with Paget's disease without underlying breast cancer, according to the National Comprehensive Cancer Network 1
For patients with associated breast cancer, the National Comprehensive Cancer Network recommends removing the nipple-areola complex with negative margins and the peripheral cancer, as well as whole-breast radiation therapy if a breast-conserving approach is used 1

In male patients, nipple lesions carry a 23-57% malignancy risk and warrant the same aggressive evaluation, according to the American College of Radiology 2, 5
The American College of Radiology notes that 4-20% of Paget's disease cases have no underlying breast malignancy on imaging or even final pathology, but biopsy is still mandatory 2
