• pleomorphic adenoma with extensive squamous metaplasia

  23 April

  Synopsis
  pleomorphic adenoma with extensive squamous metaplasia +/- keratin cyst formations squamous metaplasia, sometimes with the formation of keratin pearls, can be present. possible formation of extensive keratin-filled cysts lined by squamous epithelium. Extensive squamous metaplasia can be mistaken for malignancy, including mucoepidermoid carcinoma and squamous cell carcinoma.

  salivary mucoepidermoid carcinoma (of the salivary glands)
  squamous cell carcinoma of salivary glands The squamous cell carcinoma of submandibular salivary gland is a malignant epithelial tumor of major salivary glands composed of epidermoid cells / squamous cells. squamous cell carcinoma of salivary glands accounts for about 0.9-4.7% of all salivary gland tumors with a predilection to occur in parotid gland due to perinodal involvement. Primary squamous cell carcinoma of (...)

  Vaginal intraepithelial neoplasia (VAIN) PO
  Definition: Vaginal intraepithelial neoplasia (VAIN) is defined as presence of squamous cell dysplasia without invasion.
  VAIN is classified in a similar manner to CIN:
  VAIN 1: mild dysplasia
  VAIN 2: moderate dysplasia
  VAIN 3: severe dysplasia / carcinoma in situ
  It is classified according to the depth of epithelial involvement:
  VAIN 1 involves lower one third of epithelium
  VAIN 2 involves lower two thirds of epithelium
  VAIN 3 (...)

• differentiated vulvar intraepithelial neoplasia

  19 April

  differentiated vulvar intraepithelial neoplasia p16- "simplex" or "differentiated type", negative for HPV and affecting elderly women. Premenopausal women are more likely to get usual type VIN, associated with HPV. Postmenopausal women are more likely to get differentiated (aka simplex) type VIN, associated with vulvar dermatoses. VIN, differentiated type is associated with vulvar dermatoses such as lichen sclerosus, and is HPV negative, p16 (INK4A) negative. It tends to have high p53 (...)

  uVIN; usual type VIN WKP PO
  Definition : Vulvar intraepithelial neoplasia (VIN) is "usual type" or "classic type", related to human papillomavirus (HPV) infection and affecting relatively young women.
  The usual type includes warty type, basaloid type and mixed (warty and basaloid) type.
  The usual type is HPV associated - it is positive for p16, negative or has low indices for p53, and MIB-1 is strongly positive above the basal layer.
  VIN, usual type (including the (...)
