Malignant neoplasms of the vulva
Overview
Most common malignancies of vulva:
Invasive squamous cell carcinoma.
Malignant melanoma.
Vulvar squamous cell carcinoma
===General===
Most common vulvar malignancy.
Precursor lesions for SCC
Vulvar intraepithelial neoplasia (VIN).
VIN can be divided into:
Classic VIN, and
Differentiated VIN.
Differentiated VIN is mostly irrelevant as it is basically never seen alone, i.e. it usually accompanies cancer.
Low grade pre-cancerous lesions (VIN) are typically HPV positive, while high grade pre-cancerous lesions and cancer are less often HPV positive.[13]
===Microscopic===
Like SCC elsewhere.
Microinvasion: <=1 mm stromal invasion, tumour size <=2 cm (T1a).[14]
Depth from DE junction.
Note:
Tumour thickness != depth of invasion.
Thickness = granular layer or surface (no granular layer present) to deepest tumour.
Depth of invasion = epithelial-stromal junction in "valley" of papillae.
DDx:
Classic vulvar intraepithelial neoplasia - esp. tangential sections.
Differentiated vulvar intraepithelial neoplasia.
Sign out
VULVA, LEFT SIDE, (INCISIONAL) BIOPSY:
- INVASIVE SQUAMOUS CELL CARCINOMA.
-- PLEASE SEE TUMOUR SUMMARY.
TUMOUR SUMMARY - VULVA
Specimen Size: multiple fragments - up to 2.5 cm in aggregate.
Tumour site: left vulva - around Bartholin's gland.
Tumour size: at least 10 mm, cannot be determined due to fragmentation.
Tumour focality: cannot be determined.
Histologic type: squamous cell carcinoma with focal keratinization.
Histologic Grade: G2 - moderately differentiated.
Microscopic tumour extension: greater than 2 mm, assessment limited by
fragmentation and tissue orientation.
Tumour border: infiltrating.
Lymph-Vascular Invasion: present.
Additional findings:
Vulvar intraepithelial neoplasia (VIN) 3 (severe dysplasia/carcinoma in situ).
