| verrucous carcinoma | <tumour> A well differentiated papillary squamous cell carcinoma, especially of the oral cavity or penis, that may invade locally but rarely metastasizes; the usual cytologic features of malignancy are absent. (05 Mar 2000) |
|---|
| carcinoma, verrucous | A variant of well-differentiated epidermoid carcinoma that is most common in the oral cavity, but also occurs in the larynx, nasal cavity, oesophagus, penis, anorectal region, vulva, vagina, uterine cervix, and skin, especially on the sole of the foot. Most intraoral cases occur in elderly male abusers of smokeless tobacco. The treatment is surgical resection. Radiotherapy is not indicated, as up to 30% treated with radiation become highly aggressive within six months. (12 Dec 1998) |

| verrucous haemangioma | A variant of the angiomatous nevus, appearing at birth or in early childhood, situated on the lower extremities with bluish-red nodules and warty surface; they enlarge and sometimes have satellite lesions. (05 Mar 2000) |
| verrucous hyperplasia | A non-invasive precursor of verrucous or squamous carcinoma of the oral mucosa, occurring in the elderly, characterised by sharp or blunt upward papillary projections of squamous epithelium. (05 Mar 2000) |
| verrucous nevus | A skin-coloured or darker wartlike, often linear, lesion appearing at birth or early in childhood, and occurring in various sizes and locations, single or multiple. (05 Mar 2000) |
| verrucous scrofuloderma | A tuberculous skin lesion having a warty surface with a chronic inflammatory base seen on the hands in adults and lower extremities in children, with marked hypersensitivity to tuberculous antigens. See: postmortem wart. Synonym: lupus papillomatosus, lupus verrucosus, tuberculous wart, verrucous scrofuloderma. (05 Mar 2000) |
| verrucous vegetations | Wart-like vegetations sometimes due to endocarditis, also related to degenerative changes on the valves and amyloidosis. (05 Mar 2000) |
| verrucous xanthoma | A papilloma of the oral mucosa and skin in which squamous epithelium covers connective tissue papillae filled with large foamy histiocytes. Synonym: histiocytosis Y. (05 Mar 2000) |
| nonbacterial verrucous endocarditis | Verrucous endocarditis sometimes associated with disseminated lupus erythematosus. Synonym: atypical verrucous endocarditis, Libman-Sacks syndrome, nonbacterial verrucous endocarditis. (05 Mar 2000) |

| adenoid cystic carcinoma | <tumour> A histologic type of carcinoma characterised by large epithelial masses containing round, glandlike spaces or cysts which frequently contain mucus or collagen and are bordered by a few or many layers of epithelial cells without intervening stroma, forming a cribriform pattern like a slice of Swiss cheese; perineural invasion and haematogenous metastasis are common; occurs most commonly in salivary glands. Synonym: cylindromatous carcinoma. (05 Mar 2000) |
| adenoid squamous cell carcinoma | <tumour> A malignant neoplasm consisting chiefly of glandular epithelium (adenocarcinoma), usually well differentiated, with foci of metaplasia to squamous (or epidermoid) neoplastic cells. Synonym: adenoid squamous cell carcinoma. (05 Mar 2000) |
