Extramammary Paget's disease is a rare malignant neoplasm characterized by changes in the skin and underlying tissues that are outside the nipples of the mammary gland. The disease is usually associated with invasive breast cancer, but unlike classic Paget's disease, its manifestations can develop in various areas of the body, including the genitals, anal area, and other areas of the skin. The extramammary form has its own diagnostic and treatment features, which requires attention from medical specialists.
History of the disease and interesting historical facts
Extramammary Paget's disease was first described in the late 19th century. It was named after the French physician Edmond Paget, who in 1874 reported his observations of skin lesions in the nipple area associated with carcinoma. In the following years, cases of the extramammary form, known as "extramammary Paget's disease", were reported. Research continued for decades, but it was not until the 20th century that the disease was found to have specific clinical and pathogenetic characteristics. For example, in 2005, a number of studies were conducted that allowed a better understanding of the molecular biology of this pathology and its relationship with other malignancies.
Epidemiology
Extramammary Paget's disease is a rare disease. Statistics show that there are only 1-3 new cases per 100,000 people per year. The gender ratio shows a higher incidence in women than in men, but cases in men have also been recorded. According to studies, most patients are elderly, and the average age at diagnosis is about 60-70 years.
Genetic predisposition to this disease
Although the genetic predisposition to extramammary Paget's disease remains unknown, research suggests that certain genes may play a role in the development of the disease. In particular, changes in the TP53 and HER2 genes have been associated with an increased risk of malignancies, including Paget's disease. Genetic mutations such as BRCA1 and BRCA2 may also increase the likelihood of developing cancers in women and, to some extent, in men, highlighting the importance of genetic screening for susceptible populations.
Risk factors for the development of this disease
Risk factors that contribute to the development of extramammary Paget's disease include:
- Age - the risk increases with age.
- Genetic predisposition - having a family history of cancer.
- Smoking can contribute to the pathogenesis of various malignant tumors.
- Chemical exposure - long-term exposure to carcinogens.
- Human papillomavirus infection - some strains are associated with the development of skin cancer.
Diagnosis of this disease
Diagnosis of extramammary Paget's disease requires careful consideration because symptoms may resemble other skin conditions. Key symptoms include:
- Redness and itching in the affected area.
- Peeling and erosion of the skin.
- Compaction of underlying tissues.
Laboratory tests, such as biopsy, are needed to confirm the diagnosis. Radiological examinations, including ultrasound and MRI, can be used to assess the extent of the disease. It is important to differentiate the disease from other forms of skin disease, including eczema and psoriasis.
Treatment
Treatment for extramammary Paget's disease depends on the stage of the disease and may include:
- General treatment - aimed at improving the quality of life and symptomatic treatment.
- Pharmacological treatment - includes antitumor drugs such as taxol and anthracyclines.
- Surgical treatment - may include resection of the affected area of skin.
- Other treatments, such as immunotherapy and radiotherapy, may be used depending on clinical findings.
List of medications used to treat this disease
Medications recommended for the treatment of extramammary Paget's disease include:
- Cisplatin
- Doxorubicin
- Paclitaxel
- Imitozan
- Fluorouracil
Disease monitoring
Monitoring of patients with extramammary Paget's disease includes regular examinations, clinical assessments, and laboratory monitoring. The recurrence rate is approximately 30%, highlighting the importance of long-term follow-up. Prognosis depends on the stage at presentation and the presence of metastases. Potential complications may include recurrence and lymph node metastases.
Age-related features of the disease
Different age groups exhibit different disease patterns. Older patients may have more aggressive disease, while younger patients may have less severe symptoms. Patients over 70 years of age are also more likely to have underlying medical conditions, which can complicate diagnosis and treatment.

Advice from Dr. Oleg Korzhikov on this disease
Dr. Oleg Korzhikov recommends that patients with extramammary Paget's disease not ignore any changes in the skin condition and be sure to undergo regular examinations. "The disease indicators can be very changeable, and rapid intervention provides the best prognosis," he emphasizes. The doctor also advises maintaining a healthy lifestyle, including proper nutrition and physical activity, which can help maintain overall health and prevent relapses.
