Vulvar Sweat Gland Cancer: An Obsolete Entity

Vulvar sweat gland cancer, also known as mucinous adenocarcinoma of the sweat glands, is a rare and obsolete form of cancer that primarily affects the vulva. This type of cancer originates from the sweat glands in the vulvar region.

Characteristics and Symptoms

• Rare occurrence: Vulvar sweat gland cancer is an exceedingly rare entity, with only a few reported cases in medical literature.
• Age and gender: It mainly affects older women, typically those aged 70-79 years.
• Symptoms: The symptoms of this cancer are not well-documented, but it's believed to be asymptomatic in its early stages.

Historical Context

The case described in [3] by KY Yeung in 1977 is one of the earliest recorded instances of vulvar sweat gland cancer. This case highlights the rarity and unusual nature of this type of cancer.

Comparison with Other Vulvar Cancers

Vulvar sweat gland cancer should not be confused with other types of vulvar cancers, such as squamous cell carcinoma or Paget's disease, which are more common and have distinct characteristics.

Current Status

Due to its rarity and lack of documented cases, vulvar sweat gland cancer is considered an obsolete entity in modern medical literature. However, it serves as a reminder of the complexities and nuances of human anatomy and the importance of continued research into rare and unusual conditions.

Vulvar Sweat Gland Cancer (Adenocarcinoma) Signs and Symptoms

Vulvar sweat gland cancer, also known as adenocarcinoma, is a rare type of cancer that affects the vulvar sweat glands or Bartholin's glands on the side of the vaginal opening. The early warning signs and symptoms of this condition can be subtle and may be misattributed to more common inflammatory skin conditions.

Common Signs and Symptoms:

• A distinct mass or lump on the vulva, which can be flesh-colored, white, red, or pink in color [3][5]
• Moles on the vulva that are unusual in shape or size [3]
• Lumps or bumps on the vulva that do not go away [6][7]
• Color changes on the vulva, such as skin looking darker or lighter than usual, or patches of white skin [13][14]
• Itching, burning, or pain in the vulvar area [7]

Rare Signs and Symptoms:

• An ulcer or open wound for a prolonged period [6]
• A lump or enlarged lymph node in the groin area [5]
• Abnormalities in the Bartholin's glands, such as a lump on either side of the vaginal opening [14]

It is essential to note that these symptoms can also be indicative of other conditions, and only a medical professional can accurately diagnose vulvar sweat gland cancer. If you are experiencing any unusual symptoms or changes in your body, it is crucial to consult with a healthcare provider for proper evaluation and treatment.

Diagnostic Tests for Obsolete Vulvar Sweat Gland Cancer

Vulvar sweat gland cancer, also known as adenocarcinoma of the vulva, is a rare type of cancer that affects the vulvar sweat glands or Bartholin's glands. While it is considered obsolete in modern medical practice, there are still some diagnostic tests that can be used to detect this condition.

• Physical Exam: A thorough physical examination by a healthcare provider is often the first step in diagnosing vulvar sweat gland cancer. This may involve a pelvic exam and a visual inspection of the vulva.
• Biopsy: The only definitive test for vulvar sweat gland cancer is a biopsy, which involves removing a sample of tissue from the affected area for laboratory testing. A pathologist will examine the tissue sample under a microscope to determine if cancer or pre-cancer cells are present.
• Imaging Tests: Imaging tests such as MRI (magnetic resonance imaging) or PET (positron emission tomography) scans may be recommended prior to treatment to determine if any cancer cells have spread. These tests can help identify the extent of the disease and guide further treatment decisions.

It's worth noting that vulvar sweat gland cancer is a rare condition, and most cases are diagnosed in older women. The five-year survival rate for this type of cancer is relatively high, at around 71% [6]. However, early detection and diagnosis are crucial for effective treatment and improved outcomes.

• A pathologist (a doctor specially trained to diagnose diseases with laboratory tests) will look at the tissue sample with a microscope to see if cancer or pre-cancer cells are present and, if so, what type it is. [10]
• Some advanced cases of vulvar cancer can spread to the bladder, so any suspicious areas noted during this exam are biopsied. This may involve removing a sample of skin for testing in a lab. [10]
• MRI or PET scan may be recommended prior to treatment to determine if any cancer cells have spread. These tests are performed as an outpatient and require placement of an IV during the test. [13]

The differential diagnosis for vulvar sweat gland cancers, particularly those considered obsolete, involves a range of conditions that can mimic the symptoms and characteristics of these rare tumors.

• Squamous cell carcinoma: This is the most common type of vulvar cancer, accounting for 75% of cases. It can present with similar symptoms to sweat gland carcinomas, such as a vulvar mass or lesion.
• Adenocarcinoma: Arising from the Bartholin glands or sweat glands in the vulva, adenocarcinomas are another type of vulvar cancer that can be considered in the differential diagnosis.
• Extramammary Paget's disease: This is a rare cancer that starts near sweat glands in the skin and most often affects the skin of the vulva. It can present with similar symptoms to sweat gland carcinomas, such as a vulvar mass or lesion.
• Syringoid eccrine carcinoma: A rare but distinctive sweat gland tumor with an indolent disease course, syringoid eccrine carcinoma should be considered in the differential diagnosis of vulvar cancers.
• Adnexal tumors: These are tumors that arise from the skin and subcutaneous tissue surrounding the vulva. They can present with similar symptoms to sweat gland carcinomas, such as a vulvar mass or lesion.

According to [10], when a vulvar mass is present, the diagnosis of AMGT (apocrine mixed gland tumor) should be suspected, especially if a history of breast malignancy or other adnexal tumors is present.
