Condyloma acuminatum
Condyloma acuminatum, also genital wart, is a common benign pathology of the genital region (vulva, penis, perineum).
The Bethesda system includes condyloma acuminatum in LSIL.[1]
General
- Due to human papillomavirus (HPV).
- Transmission: sexual, non-sexual, horizontal (mother to child).[2]
- Should raise the suspicion of child abuse.
- Transmission: sexual, non-sexual, horizontal (mother to child).[2]
Note:
- Related to verruca vulgaris (common wart).
Clinical DDx:
Microscopic
Features:
- Koilocytes.[4]
- Cells with an enlarged nucleus and perinuclear clearing.
- Papillomatosis.[5]
- Papillomatosis = surface elevation due to dermal papillae enlargement.[6]
- +/-Parakeratosis.
DDx:
- Classic vulvar intraepithelial neoplasia - architecture different.

Micro
The sections show a polypoid fragment of skin with epithelium on three sides, acanthosis, hyperkeratosis and parakeratosis. Koilocytic changes (mild nuclear enlargement, perinuclear clearing) are seen focally. There is mild basilar nuclear enlargement and hyperchromasia. The epithelium shows maturation to the surface and a granular layer is present.
Seborrheic keratosis-like
The sections show skin with acanthosis with papillomatous features (round bulbous rete ridges, acanthosis with penetrating fibrovascular cores) pseudohorn cysts, parakeratosis and hyperkeratosis. There is no significant basal nuclear atypia. There are no mitoses and no melanocytic nests. There is mild dermal inflammation. There is no solar elastosis. Pigment incontinence is present focally.
