A peculiar case of Paget’s disease of the breast

Mammary Paget’s disease is a disorder of the nipple-areola complex of the breast that, while rare, is often associated with an underlying carcinoma. The typical aspect is usually an eczematoid change of the nipple or a red and ulcerative nipple’s lesion or erythematous and crusted lesion, with or without mass-like lesion and infiltration and inversion of the nipple. It was described at first by Sir James Paget in 1874, [1] who classified the disease in mammary and extramammary type. The mammary type (Paget’ s Breast Cancer: PBC) has rare frequency. PBC occurs in 0.5-5% of all cases of breast cancer, it affects the mouth of the excretory ducts of the nipple, which is characterized by lesion of nipple’s large ducts. PBC can be a superficial lesion or a nodule-tumor and it can be associated with underlying carcinoma in situ (DCIS) in more than 95% of cases, especially in postmenopausal women. In a small percentage of cases, PBC can also be associated with an invasive breast cancer. Accuracy in the diagnostic phase, in order to distinguish PBC from others diseases is paramount and histological examination of lesion’s biopsy has a crucial role. Prognosis and treatment depend on the type of underlying breast cancer and are based on the stage of cancer, but more importantly, on the prompt of an adequate multidisciplinary diagnostic pathway.
