Extramammary Paget’s Disease (EMPD) is a rare skin cancer that primarily affects areas with high concentrations of sweat and sebaceous glands, such as the genital, perianal, and axillary regions. This guide provides a detailed overview of EMPD, including its definition, pathophysiology, types, causes, symptoms, diagnostic tests, treatments, prevention strategies, and frequently asked questions. Written in simple language, this article aims to enhance your understanding and improve visibility for those seeking information about EMPD.
Extramammary Paget’s Disease is a rare form of skin cancer that typically occurs in areas rich in apocrine glands, such as the genital, anal, and armpit regions. It resembles eczema or dermatitis, making it challenging to diagnose early. EMPD primarily affects older adults and may be associated with underlying malignancies in some cases.
Key Points:
- Rare skin cancer
- Commonly found in genital, perianal, and axillary areas
- Resembles skin conditions like eczema
- Often diagnosed in older adults
Pathophysiology
Understanding the pathophysiology of EMPD involves exploring its structure, blood supply, and nerve supply.
Structure
EMPD originates in the epidermis, the outermost layer of the skin. It involves malignant glandular cells called Paget cells, which spread within the epidermis and can invade deeper tissues.
Blood Supply
The blood supply to the affected areas is crucial for tumor growth. EMPD relies on local blood vessels to receive nutrients and oxygen, facilitating the spread of cancerous cells.
Nerve Supply
Nerve involvement in EMPD can lead to symptoms like itching or pain. The proximity of EMPD to nerve endings in sensitive areas contributes to these discomforting sensations.
Types of Extramammary Paget’s Disease
EMPD can be classified based on its association with underlying malignancies and its location.
- Primary EMPD: Occurs without an associated internal malignancy. It originates directly from the skin’s apocrine glands.
- Secondary EMPD: Associated with internal cancers, such as colorectal, bladder, or prostate cancer.
- Invasive EMPD: The cancer cells penetrate deeper into the skin layers or nearby tissues.
- Non-invasive EMPD: Cancer cells remain confined to the epidermis.
Causes of EMPD
While the exact cause of EMPD remains unclear, several factors may contribute to its development:
- Genetic mutations
- Chronic skin irritation
- Human papillomavirus (HPV) infection
- Hormonal imbalances
- Age-related changes in the skin
- Weakened immune system
- Exposure to carcinogens
- Family history of skin cancer
- Obesity
- Smoking
- Excessive sun exposure
- Poor hygiene
- Pre-existing skin conditions
- Radiation exposure
