Definition / general
- Cervical cancer precursor lesion (Int J Cancer 2006;119:888)
- Subcategory of LSIL
Terminology
- Also known as exophytic condyloma, mature exophytic LSIL
Epidemiology
- True prevalence unknown, up to 3.0% of Pap smears reported as SIL
- Incidence may decrease in younger women following HPV vaccine (Am J Public Health 2012;102:833)
Sites
- Transformation zone, exocervix
Etiology
- Strongly associated with HPV subtypes 6 and 11
Clinical features
- Commonly sexually transmitted, peaks second and third decade
- Tends to recur; enlarges during pregnancy; may regress without treatment
- May be diagnosed as ASC-US if all features are not present
Radiology description
- Raised polypoid or papillary lesion with prominent vasculature
Variants
- Giant Condyloma: uncommon but important variant, presents as large tumor of cervix and distal vagina, misdiagnosed as verrucous carcinoma (Am J Surg Pathol 2013;37:300)
- Immature condyloma / papillary immature metaplasia: metaplastic squamous cells with nuclear enlargement, occasional binucleation, uniform nuclear contours, minimal hyperchromasia (Diagn Cytopathol 1998;18:416)
Treatment
- Excisional biopsy, diathermy or laser vaporization
Gross description
- Typically multifocal, white and exophytic; may be papillary
Microscopic (histologic) description
- Characterized by verruciform growth pattern with blunt shaped papillae acanthosis, atypical parakeratosis and hyperkeratosis, koilocytosis in middle and upper epithelium, minor atypia is common
Cytology description
- See Cervix-Cytology
Positive stains
- KI67 stains basal to intermediate cells (Cancer 1991;68:1340)
Negative stains
- p16 usually weak or negative (Am J Surg Pathol 2001;25:884)
Electron microscopy description
- Viral particles contained in nuclei of superficial epithelial cells, most particles are single and either freely scattered throughout nucleoplasm or closely associated with chromatin clumps (J Clin Pathol 1981;34:532
Molecular / cytogenetics description
- PCR yields 100% detection rate of HPV 6 and HPV11 (Yi Chuan 2005;27:699)
Differential diagnosis
- Filiform mucosal excrescences of vagina: no prominent acanthosis, no nuclear atypia, no atypical parakeratosis
- Squamous papilloma: thick fibrovascular core, lacks hyperkeratosis and koilocytosis
