The Vulvar Extramammary Pagets Disease
The Vulvar Extramammary Pagets Disease Vulvar Extramammary Paget’s Disease (EMPD) is a rare, slow-growing skin cancer that primarily affects the vulvar area, which includes the external female genitalia. Although it shares similarities with Paget’s disease of the breast, EMPD occurs outside the mammary glands, making it an extramammary manifestation. Its rarity and subtle presentation often lead to delayed diagnosis, emphasizing the importance of awareness among clinicians and patients alike.
The Vulvar Extramammary Pagets Disease Typically, EMPD presents as a persistent, red, or eczematous lesion on the vulva that may be itchy, burning, or irritated. These symptoms are often mistaken for common dermatological conditions such as dermatitis, eczema, or fungal infections, which can delay appropriate diagnosis. The lesions tend to be well-demarcated, solitary or multiple, and may sometimes ulcerate or develop crusts. The disease predominantly affects women over the age of 50, although cases in younger women are also reported.
The exact cause of vulvar EMPD remains unclear, but it is believed to originate either from epidermal cells or as a manifestation of underlying malignancies. In some cases, EMPD is associated with intraepithelial carcinoma or invasive vulvar cancer. Moreover, there is a subset of cases where the disease results from a primary intraepithelial lesion, while in others, it reflects a secondary extension from an underlying visceral malignancy such as gastrointestinal or urological cancers. Therefore, comprehensive evaluation for associated malignancies is crucial when EMPD is diagnosed.
Diagnosis typically requires a biopsy of the lesion, which reveals characteristic histopathological features. Under the microscope, Paget’s cells—large, round cells with abundant pale cytoplasm—are seen scattered within the epidermis. Immunohistochemistry stains further assist in diagnosis, with markers such as cytokeratin 7 (CK7) positivity indicating glandular origin, while negativity for other markers helps differentiate EMPD from other skin conditions.

The Vulvar Extramammary Pagets Disease Treatment primarily involves surgical excision with clear margins to remove all diseased tissue. Due to the often ill-defined borders of the lesion, wide local excision is recommended. However, recurrence rates can be high, partly because of the difficulty in achieving complete removal. Alternative or adjunctive treatments include laser therapy, topical imiquimod, radiotherapy, and Mohs micrographic surgery, especially in recurrent or difficult-to-resect cases. Regular follow-up is essential to monitor for recurrence or the development of new lesions.
The Vulvar Extramammary Pagets Disease The prognosis for vulvar EMPD varies depending on whether the disease is localized or associated with invasive carcinoma. When confined to the epidermis, the outcome is generally favorable with appropriate treatment. However, the presence of invasive disease or associated malignancies worsens the prognosis, underscoring the importance of early detection and comprehensive management.
In summary, vulvar extramammary Paget’s disease is a rare, often misdiagnosed condition that requires heightened clinical suspicion. Accurate diagnosis through biopsy and histopathology is vital for effective treatment. While surgical excision remains the cornerstone of therapy, ongoing research seeks less invasive options to improve patient outcomes and reduce recurrence rates. Awareness among healthcare providers can facilitate earlier diagnosis, better management, and ultimately, improved quality of life for affected women. The Vulvar Extramammary Pagets Disease
