Vulvar and vaginal lesions

Vulvar and Vaginal lesions

Dr.FBehnamfar MD


Introduction

Introduction

Most usful means of generating differential diagnosis is by morphological findings rather than symptomatology

Vulvar biopsy should be performed if the lesion is clinically suspicious or does not resolve after standard therapy


Vulvar symptoms

Vulvar Symptoms

  • Most often,primary vaginitis and secondary vulvitis

  • A number of skin conditions on other areas of the body


Neoplasia

Neoplasia

  • Vulvar intraepithelial neoplasia

    a precancerous lesion that may progress to invasive cancer

  • Most are raised multifocal white (may be red or pink) and/or verrucous lesions

  • Cancer presents with unifocal vulvar plaque,ulcer or mass

  • Lichen scerosus and erosive lichen planus predispose to cancer


Genital warts

Genital warts

  • Caused by human papillomavirus

  • Flat,filliform or verrucous,or giant

  • Flesh colored or pigmented

  • Biopsy is indicated if there is rapid growth,increased pigmentation,ulceration,pigmentation,fixation or poor response to therapy

  • Treatment : trichloroacetic acid, podophyllum,Cryo,laser

  • Not curative ,merely speed clinical resolution


White patch

White patch

  • Lichen sclerosus,well demarcated white finely wrinkled and atrophic patches

  • Vulvar itching and typical findings

  • Potent topical corticosteriod ointment

  • Close follow up for risk of malignancy


Other vulvar conditions

Other vulvar conditions

  • folliculitis

  • Fox.fordiyce disease

  • Acanthosis nigricans

  • Extramammary pagets disease,intraepithelial adenocarcinoma


Vulvar and vaginal lesions

  • Herpes simplex

  • Scabis


Vulvar cysts tumors and masses

Vulvar cysts, tumors and masses

  • Condylomata accuminata

  • duct cysts,Skenes duct cysts

  • Vulvar Ulcers: Behcet disease,lichen planus


Vaginal conditions

Vaginal Conditions

  • Retained foreign body

  • Ulceration

  • Malignancy


Vulvar cancer

Vulvar Cancer

  • 3870 new cases 2005

  • 870 deaths

  • Approximately 5% of Gynecologic Cancers

American Cancer Society. Cancer Facts & Figures. 2004. Atlanta, GA; 2005


Vulvar cancer1

Vulvar Cancer

  • 85% Squamous Cell Carcinoma

  • 5% Melanoma

  • 2% Sarcoma

  • 8% Others


Vulvar cancer2

Vulvar Cancer

  • Biphasic Distribution ,two distinct etiologies:

    • Age 70

    • type, unifocal,

    • in areas adjacent to lichen sclerosus or squamous hyperplasia (Chronic inflammatory conditions)

    • 20% in patients UNDER 40 and appears to be increasing,

    • multifocal,

    • basaloid or warty types,

    • HPV related,smoking and VIN


Vulvar cancer3

Vulvar Cancer

  • Paget’s Disease of Vulva

    • 10% will be invasive

    • 4-8% association with underlying Adenocarcinoma of the vulva


Symptoms

Symptoms

  • Most patients are treated for “other” conditions

  • 12 month or greater time from symptoms to diagnosis


Symptoms1

Symptoms

  • Pruritus

  • Mass

  • Pain

  • Bleeding

  • Ulceration

  • Dysuria

  • Discharge

  • Groin Mass


Symptoms2

Symptoms

  • May look like:

    • Raised

    • Erythematous

    • Ulcerated

    • Condylomatous

    • Nodular


Vulvar cancer4

Vulvar Cancer

  • IF IT LOOKS ABNORMAL ON THE VULVA

  • BIOPSY!

  • BIOPSY!

  • BIOPSY!


Tumor spread

Tumor Spread

  • Very Specific nodal spread pattern

  • Direct Spread

  • Hematogenous


Staging

Staging

  • Based on TNM Surgical Staging

    • Tumor size

    • Node Status

    • Metastatic Disease


Staging1

Staging

  • Stage I T1 N0 M0

    • Tumor ≤ 2cm

    • IA≤1 mm depth of stromal Invasion

    • IB1 mm or more depth of invasion


Staging2

Staging

  • Stage II T2 N0 M0

    • Tumor >2 cm

    • Confined to Vulva or Perineum


Staging3

Staging

  • Stage III

    • T3 N0 M0

    • T3 N1 M0

    • T1 N1 M0

    • T2 N1 M0

      • Tumor any size involving lower urethra, vagina, anus OR unilateral positive nodes


Staging4

Staging

  • Stage IVA

    • T1 N2 M0

    • T2 N2 M0

    • T3 N2 M0

    • T4 N any M0

      • Tumor invading upper urethra, bladder, rectum, pelvic bone or bilateral nodes


Staging5

Staging

  • Stage IVB

    • Any T Any N M1

      • Any distal mets including pelvic nodes


Treatment

Treatment

  • Primarily Surgical

    • Wide Local Excision

    • Radical Excision

    • Radical Vulvectomy with Inguinal Node Dissection

      • Unilateral

      • Bilateral

      • Possible Node Mapping, still investigational


Treatment1

Treatment

  • Local advanced may be treated with Radiation plus Chemosensitizer

  • Positive Nodal Status

    • 1 or 2 microscopic nodes < 5mm can be observed

    • 3 or more or >5mm post op radiation


New advances in treatment

New advances in treatment

  • Individualization of treatment,vulvar conservation for unifocal tumors

  • Elimination of routine pelvic lymphadenectomy

  • Omission of groin dissection for T1 tumors (<1mm stromal invasion)

  • Separate incisions improve wound healing


Treatment2

Treatment

  • Special Tumor

    • Verrucous Carcinoma

      • Indolent tumor with local disease, rare mets UNLESS given radiation, becomes Highly malignant and aggressive

      • Excision or Vulvectomy ONLY


Vulva 5 year survival

Vulva 5 year survival

  • Stage I90

  • Stage II77

  • Stage III51

  • Stage IV18

Recurrence

Recurrence

  • Local Recurrence in Vulva

    • Reexcision or radiation and good prognosis if not in original site of tumor

    • Poor prognosis if in original site


Recurrence1

Recurrence

  • Distal or Metastatic

    • Very poor prognosis, active agents include Cisplatin, mitomycin C, bleomycin, methotrexate and cyclophosphamide


Melanoma

Melanoma

  • 5% of Vulvar Cancers

  • Not UV related

  • Commonly periclitoral or labia minora


Melanoma1

Melanoma

  • Microstaged by one of 3 criteria

    • Clark’s Level

    • Chung’s Level

    • Breslow


Melanoma treatment

Melanoma Treatment

  • Wide local or Wide Radical excision with bilateral groin dissection

  • Interferon Alpha 2-b


Vaginal carcinoma

Vaginal Carcinoma

  • 2140 new cases projected 2005

  • 810 deaths projected 2005

  • Represents 2-3% of Pelvic Cancers

American Cancer Society. Cancer Facts & Figures. 2004. Atlanta, GA; 2005


Vaginal cancer

Vaginal Cancer

  • 84% of cancers in vaginal area are secondary

    • Cervical

    • Uterine

    • Colorectal

    • Ovary

    • Vagina

Vaginal carcinoma1

Vaginal Carcinoma

  • Squamous Cell80-85%

  • Clear Cell10%

  • Sarcoma3-4%

  • Melanoma2-3%


Clear cell carcinoma

Clear Cell Carcinoma

  • Associated with DES Exposure In Utero

    • DES used as anti abortifcant from 1949-1971

    • 500+ cases confirmed by DES Registry

    • Usually occurred late teens


Vaginal cancer etiology

Vaginal Cancer Etiology

  • Mimics Cervical Carcinoma

    • HPV 16 and 18


Staging6

Staging

  • Stage IConfined to Vaginal Wall

  • Stage IISubvaginal tissue but not to pelvic sidewall

  • Stage IIIExtended to pelvic sidewall

  • Stage IVABowel or Bladder

  • Stage IVBDistant mets


Treatment3

Treatment

  • Surgery with Radical Hysterectomy and pelvic lymph dissection in selected stage I tumors high in Vagina

  • All others treated with radiation with chemosensitization
