Extramammary Paget's disease (EMPD) is a rare and slow-growing cancer, which occurs within the epithelial tissues [1] and accounts for 6.5% of all Paget's disease. [2] This disease presents similarly to the more conventional form of mammary Paget's disease (MPD). [ 3 ]
Paget's disease of the breast (also known as mammary Paget's disease) is a rare skin change at the nipple nearly always associated with underlying breast cancer. [2] Paget's disease of the breast was first described by Sir James Paget in 1874. [3] The condition is an uncommon disease accounting for 1 to 4% of all breast cancers cases.

Squamous cell carcinoma, melanoma in situ, Pagetoid Bowen's disease, ocular sebaceous carcinoma, and other carcinomas can all display pagetoid growth. The term pagetoid (i.e., 'Paget-like') is derived from the extramammary Paget's disease, wherein the large tumour cells are arranged singly or in small clusters within the epidermis and its ...
Extramammary Paget's disease; Tumors of melanocytes, noninvasive; Invasive disease (vulvar carcinoma) The ISSVD further revised this classification in 2004, replacing the three-grade system with a single-grade system in which only the high-grade disease is classified as VIN. VIN is subdivided into: (Robbins Pathological Basis of Disease, 9th Ed)
Paget's disease may refer to several conditions described by Sir James Paget, surgeon and pathologist: Paget's disease of bone (most common use of the term "Paget's disease") Paget's disease of the breast; Paget–Schroetter disease; Paget's abscess; Extramammary Paget's disease (EMPD)
Rarely, papillary hidradenomas have progressed to what appear to be 1) in situ malignancies (i.e. malignancies that have neither metastasized nor invaded beyond the layer of tissue where they arose); 2) locally invasive malignancies; [10] [11] or 3) complex tumors intermixed with other malignancies such as extramammary Paget disease, melanoma ...
Five-year survival is greater than 90% for patients with stage I lesions but decreases to 20% when pelvic lymph nodes are involved. Lymph node involvement is the most important predictor of prognosis. [38] Prognosis depends on the stage of cancer, which refers the amount and spread of cancer in the body. [39] The stages are broken into four ...
