Primary vaginal cancers are malignant tumors that originate from cells in the vagina Vagina The vagina is the female genital canal, extending from the vulva externally to the cervix uteri internally. The structures have sexual, reproductive, and urinary functions and a rich blood supply, mainly arising from the internal iliac artery. Vagina, Vulva, and Pelvic Floor: Anatomy. Squamous cell carcinoma Squamous cell carcinoma Cutaneous squamous cell carcinoma (cSCC) is caused by malignant proliferation of atypical keratinocytes. This condition is the 2nd most common skin malignancy and usually affects sun-exposed areas of fair-skinned patients. The cancer presents as a firm, erythematous, keratotic plaque or papule. Squamous Cell Carcinoma (SCC) (SCC) is by far the most common (80%–85%); other histologic types include adenocarcinomas, sarcomas (including sarcoma botryoides, typically seen in children), and melanomas. Vaginal SCC is most commonly associated with HPV HPV Human papillomavirus (HPV) is a nonenveloped, circular, double-stranded DNA virus belonging to the Papillomaviridae family. Humans are the only reservoir, and transmission occurs through close skin-to-skin or sexual contact. Human papillomaviruses infect basal epithelial cells and can affect cell-regulatory proteins to result in cell proliferation. Papillomavirus (HPV) infections Infections Invasion of the host organism by microorganisms or their toxins or by parasites that can cause pathological conditions or diseases. Chronic Granulomatous Disease, while clear cell adenocarcinomas are associated with in utero exposure to diethylstilbestrol Diethylstilbestrol A synthetic nonsteroidal estrogen used in the treatment of menopausal and postmenopausal disorders. It was also used formerly as a growth promoter in animals. According to the fourth annual report on carcinogens, diethylstilbestrol has been listed as a known carcinogen. Noncontraceptive Estrogen and Progestins (DES). Individuals typically present with vaginal bleeding and/or an irregular mass Mass Three-dimensional lesion that occupies a space within the breast Imaging of the Breast or lesion on exam; other symptoms may include abnormal discharge, pain Pain An unpleasant sensation induced by noxious stimuli which are detected by nerve endings of nociceptive neurons. Pain: Types and Pathways, and urinary or defecatory symptoms. A biopsy Biopsy Removal and pathologic examination of specimens from the living body. Ewing Sarcoma is required for diagnosis. Staging Staging Methods which attempt to express in replicable terms the extent of the neoplasm in the patient. Grading, Staging, and Metastasis is based on tumor Tumor Inflammation size, extent of local invasion, and metastasis Metastasis The transfer of a neoplasm from one organ or part of the body to another remote from the primary site. Grading, Staging, and Metastasis. Management may be surgical for stage I disease, but surgery is typically avoided in advanced disease, which is instead managed with radiation Radiation Emission or propagation of acoustic waves (sound), electromagnetic energy waves (such as light; radio waves; gamma rays; or x-rays), or a stream of subatomic particles (such as electrons; neutrons; protons; or alpha particles). Osteosarcoma and chemotherapy Chemotherapy Osteosarcoma.

Primary vaginal cancer is a malignant tumor Tumor Inflammation arising from tissue of the vagina Vagina The vagina is the female genital canal, extending from the vulva externally to the cervix uteri internally. The structures have sexual, reproductive, and urinary functions and a rich blood supply, mainly arising from the internal iliac artery. Vagina, Vulva, and Pelvic Floor: Anatomy.
The vagina Vagina The vagina is the female genital canal, extending from the vulva externally to the cervix uteri internally. The structures have sexual, reproductive, and urinary functions and a rich blood supply, mainly arising from the internal iliac artery. Vagina, Vulva, and Pelvic Floor: Anatomy is:
Vaginal malignancies may be either primary (originating from the vagina Vagina The vagina is the female genital canal, extending from the vulva externally to the cervix uteri internally. The structures have sexual, reproductive, and urinary functions and a rich blood supply, mainly arising from the internal iliac artery. Vagina, Vulva, and Pelvic Floor: Anatomy itself) or metastatic to the vagina Vagina The vagina is the female genital canal, extending from the vulva externally to the cervix uteri internally. The structures have sexual, reproductive, and urinary functions and a rich blood supply, mainly arising from the internal iliac artery.

The most common subtypes of primary vaginal cancer (originating in the vagina Vagina The vagina is the female genital canal, extending from the vulva externally to the cervix uteri internally.

Primary vaginal cancer:
The pathogenesis of SCC is usually related to HPV HPV Human papillomavirus (HPV) is a nonenveloped, circular, double-stranded DNA virus belonging to the Papillomaviridae family. Humans are the only reservoir, and transmission occurs through close skin-to-skin or sexual contact. Human papillomaviruses infect basal epithelial cells and can affect cell-regulatory proteins to result in cell proliferation. Papillomavirus (HPV) infections Infections Invasion of the host organism by microorganisms or their toxins or by parasites that can cause pathological conditions or diseases. Chronic Granulomatous Disease. The pathogenesis of other types is less well characterized.
Histologic examination of a biopsy Biopsy Removal and pathologic examination of specimens from the living body. Ewing Sarcoma is required for a formal diagnosis of vaginal cancer. Imaging findings help with staging Staging Methods which attempt to express in replicable terms the extent of the neoplasm in the patient. Grading, Staging, and Metastasis and surgical planning. Lab assessment (aside from cytology/histology) is generally not helpful.
Imaging of the abdominopelvic and/or thoracic cavities is indicated to complement the physical exam and assist in staging Staging Methods which attempt to express in replicable terms the extent of the neoplasm in the patient. Grading, Staging, and Metastasis and surgical planning.
Vaginal cancer is staged using the TNM staging system TNM staging system Grading, Staging, and Metastasis. There are 4 major stages.
Individuals are staged based on their “highest” findings. For example, tumor Tumor Inflammation in an individual with a tumor Tumor Inflammation confined to the vagina Vagina The vagina is the female genital canal, extending from the vulva externally to the cervix uteri internally. The structures have sexual, reproductive, and urinary functions and a rich blood supply, mainly arising from the internal iliac artery. Vagina, Vulva, and Pelvic Floor: Anatomy but with positive lymph nodes Lymph Nodes They are oval or bean shaped bodies (1 – 30 mm in diameter) located along the lymphatic system. Lymphatic Drainage System: Anatomy is classified as stage III. Similarly, direct tumor Tumor Inflammation invasion into the bladder Bladder A musculomembranous sac along the urinary tract. Urine flows from the kidneys into the bladder via the ureters, and is held there until urination. Pyelonephritis and Perinephric Abscess mucosa is stage IV even if there is no lymph Lymph The interstitial fluid that is in the lymphatic system. Secondary Lymphatic Organs node involvement or distant metastasis Metastasis The transfer of a neoplasm from one organ or part of the body to another remote from the primary site. Grading, Staging, and Metastasis.

Vaginal cancer is rare, so evidence on optimal treatment approaches is lacking. Treatment recommendations are generally adopted from similar cervical and anal cancers (which are more common).
The presenting symptom in vaginal cancer is typically postcoital or postemenopausal bleeding. The differential diagnosis for these presenting symptoms includes:
Benign Benign Fibroadenoma vaginal masses may include:
