Lichen Sclerosis
thin epidermiscollagenized dermishyperkeratosis - thickening stratum corneumatrophy in stromashrinkage of introitusinflammation (autoimmune) - responds to steriodsKraurosis vulvaepainful intercourse, itching, irritationsquamous carcinoma 1-4%
Squamous Hyperplasia
lichenification (thickening or hardening) process of squamous epitheliumopposite of lichen sclerosisleukoplakia = white discolorationhyperkeratosis present above THICKENED epidermis (acanthosis)chronic inflammatory statepink-white lesion, thicker than lichen sclerosisitching - it itches, they rub on it and the epithelium thickensbiopsy to r/o neoplasm
LSIL Characteristics
low NC ratioAbnormally shaped nucleusNuclear enlargementHyperchromoplasiaIrregularityperinuclear halo with distinct borders - koilocytes
HSIL Characteristics
Less cytoplasmHigh N:C ratiosmaller cellsif you can see the nucleolus, worry about invasion
Cervical Squamous Cancer Characteristics
irregular shapeprominent macronucleusgranular chromatinsimilar to HSILnucleoli may be presentinflammatory/necrotic background - tumor diathesis
