1/5. Verruciform xanthoma in association with discoid lupus erythematosus.Verruciform xanthoma (VX) is an uncommon lesion occurring primarily in the oral cavity. Cutaneous lesions are much less common and they preferentially arise on anogenital skin. They are not necessarily associated with a pre-existing inflammatory process. We report a VX in association with a long-standing lesion of discoid lupus erythematosus (DLE) on the scalp of a 34-year-old black woman. This association, which to our knowledge has not been previously reported, is consistent with the proposed pathogenetic mechanism of entrapment and subsequent degeneration of epithelial cells in the papillary dermis of VX. Histological distinction of VX from squamous cell carcinoma, with which this lesion may be clinically confused, is straightforward.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/5. Verruca vulgaris of the larynx. Demonstration of human papillomavirus types 6/11 by in situ hybridization.Verruca vulgaris of the larynx (VVL) is a distinctly uncommon lesion related to the human papillomavirus (HPV). The clinical and pathologic features of a case involving the true vocal cords of a 37-year-old woman are presented and compared with the seven cases previously reported in the English language literature. Papillomavirus capsid antigen was detected in the excised tissue on immunostaining, and viral particles were seen by electron microscopy. in situ hybridization with biotinylated dna probes clearly demonstrated HPV types 6/11. To our knowledge, this is the first case of VVL in which the virus associated with VVL has been genotyped. The results were unexpected because verruca vulgaris of the skin, lips, and oral cavity is associated with HPV types 2 and 4. This implies that verruca vulgaris can be caused by HPV types other than 2 and 4. In addition, since HPV types 6 and 11 are also the same genotypes associated with multiple papillomatosis of the larynx, it further indicates that VVL is virologically more related to multiple papillomatosis of the larynx than to its counterpart on the skin, lips, and oral cavity. The clinical and pathologic features that distinguish VVL from other similar lesions of the larynx are also discussed.- - - - - - - - - - ranking = 2keywords = oral cavity, cavity (Clic here for more details about this article) |
3/5. Verruciform xanthoma of the vulva. Report of two cases.Two cases of verruciform xanthoma of the vulva are described. This rare lesion, previously reported to occur only in the oral cavity, is characterized by a verrucous epithelial proliferation accompanied by xanthoma cells distributed exclusively in the papillary dermis. The histologic features of the lesion are diagnostic and include (1) regular acanthosis in which the rete pegs extend to a uniform level into the dermis; (2) hyperkeratosis with parakeratosis often extending deep into the rete pegs and manifesting a massive neutrophilic infiltrate; (3) hyalinization of the collagen and infiltrates of xanthoma cells that are restricted to the papillary dermis between the rete pegs. Additionally, a lichenoid inflammatory infiltrate is seen at the periphery of the verrucous lesions, and in one case this has the pattern of classic lichen sclerosus. Verruciform xanthoma must be differentiated from verruca vulgaris, condyloma acuminatum, granular cell tumor with pseudoepitheliomatous hyperplasia, and verrucous carcinoma.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
4/5. The management of warts of the oral cavity.Heretofore most people affected by warts of the oral cavity were children, but during the past decade adults have become the most frequently seen patients with warts in the mouth. The popularity of fellatio among heterosexuals, teenagers, and adults has contributed to the spread of oral warts. Of epidemiologic interest is the observation that seldom are contacts of patients with oral warts found to have warts also. Seven cases are presented, and the methods of diagnosis and treatment are outlined.- - - - - - - - - - ranking = 5keywords = oral cavity, cavity (Clic here for more details about this article) |
5/5. Verruciform xanthoma of the skin.Verruciform xanthoma is an unusual lesion characterized by verrucous epithelial proliferation accompanied by a prominent replacement of the dermal papillae with large numbers of foamy histiocytes. Cases have been previously reported only as occurring in the oral cavity or, more rarely, on the vulva. A 16-year-old girl developed a verruciform xanthoma of the skin. The lesion appeared to arise within a large epithelia nevus involving the left inner thigh and inguinal area. This association supports the concept that verruciform xanthoma is a rare inflammatory reaction pattern that may be seen in a variety of squamous epithelial lesions characterized by verrucous hyperplasia.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
