Abstract
OBJECTIVES Reported cytologic alterations associated with high-risk human papillomavirus (HR-HPV) in oral epithelial dysplasia (HPV-OED) need further characterization. STUDY DESIGN Archival cases of high-grade oral epithelial dysplasia (hgOED) (N = 38) were assigned a cytologic score (CS) based on the average number of mitotic, karyorrhectic, and apoptotic cells per high-power field. Three groups were then generated on the basis of increasing CS: Focal (group 1, N = 14), Intermediate (group 2, N = 12), and Diffuse (group 3, N = 12). Polymerase chain reaction-based HPV genotyping and p16 immunohistochemistry were performed. RESULTS HR-HPV was found significantly more in group 3 (83.3%) compared with groups 1 and 2 (group 1&2; 42.9% and 41.7%, respectively; P = .047). HPV16 predominated in HR-HPV-positive cases (90.5%). By location, the tongue or the floor of mouth was associated with all groups (P = .04). Increasing CS was associated with a slightly younger age (P = .04) and increased expression of p16 (P = .005). CS and p16 expression were not sensitive but were highly specific predictors for HR-HPV presence. Based on limited follow-up information, HPV-OED does not differ in clinical aggressiveness compared with conventional OED. CONCLUSIONS Increased CS in hgOED is strongly associated with HR-HPV (mostly HPV16) and p16 expression. CS and p16 expression are specific predictors of HR-HPV presence. Further molecular study and long-term follow-up of HPV-OED are needed.

Abstract
BACKGROUND Bowen's disease is a well-established in situ malignancy of the epidermis. The keratin expression in Bowen's disease has been studied in many reports. However, the patterns of keratin (K) 14 expression in each case have not been closely examined. OBJECTIVES To investigate if the pattern of expression of K14 has a relationship with tumour progression, we analysed the expression patterns of K14 in relation to the nature of tumour cells, comparing tumour cells in direct contact with the dermis, tumour cells separated from the dermis, and tumour cells invading into the dermis. METHODS Twenty-seven tissue sections from 22 patients were stained with anti-K14 antibody, as well as with antilaminin and periodic acid-Schiff (PAS) staining to evaluate the conditions of the basement membrane. Staining patterns of K10 and integrin beta1, and their relationships with proliferating cell nuclear antigen (PCNA) and Ki-67 staining patterns, were also examined. RESULTS Tumour cells with no, or with obscured, basement membranes always showed positive staining for K14, while those with continuous (intact) basement membranes usually did not. Of 10 sections showing dermal involvement of Bowen's disease, five were K14 positive and five were K14 negative. All of these K14-positive sections with dermal involvement showed negative or obscured laminin and PAS staining. Most of the sections having K14-negative tumour cells with dermal involvement showed K14-positive lining cells with continuous staining with laminin and PAS-positive basement membranes. K10 was reciprocally expressed with K14 in most of the sections. Integrin beta1 was expressed in the basal layers of non-tumour epidermal cells, but not in tumour cells. Ki-67 and PCNA were expressed at high frequencies in tumour cells, clearly demarcating tumour cells from non-tumour cells. CONCLUSIONS Tumour cells separated from the dermis by lining cells were K14 negative with PAS- and laminin-positive basement membranes around them; tumour cells without lining cells were K14 positive with or without continuous basement membranes. K14 expression may be a marker of tumour progression in Bowen's disease.

Abstract
BACKGROUND/AIMS Image analysis in dermatopathology has been used for DNA ploidy analysis, morphometry, stereology, and quantitative immunohistochemistry. The object is to review image analysis in dermatopathology and evaluate these modalities and their application in pigmented lesion pathology, for elucidation of tumor behaviour and architecture and as an aid in tumor identification and prognostication. CONCLUSION Image analysis in dermapathology has a huge potential. The techniques are difficult and at present mainly used in specialized centres.

Abstract
Transplant recipient develop multiple cutaneous lesions. We have identified human papillomavirus (HPV) DNA in these lesions using three different techniques, namely polymerase chain reaction (PCR), in situ hybridization, and Southern blotting. By PCR, HPV DNA was detected in 43 of 62 samples: warts, actinic keratoses, Bowen's disease, and squamous cell carcinomas. Surprisingly, HPV 6/11, usually associated with mucosa, were frequently found in benign, premalignant, and malignant cutaneous lesions (30/43 cases). Some of these biopsies were simultaneously tested by in situ hybridization and/or Southern blotting. By in situ hybridization, HPV 6/11 were identified in two warts and one squamous cell carcinoma among 29 tissue specimens tested. Of the three samples examined by Southern blotting, HPV 6/11 were detected in one squamous cell carcinoma. In patients from a control population cutaneous biopsies did not exhibit HPV types 6/11 except in Bowen's disease; HPV types 1 or 2 were mainly found in benign warts. These findings suggest that in transplant recipients, HPV can lose their specificity towards mucosa or cutaneous epithelium. The significance of the presence of HPV 6/11 in skin lesions remains unknown.

Abstract
Cutaneous Bowen's disease (BD) and genital bowenoid papulosis (BP) are considered as precancerous or cancerous lesions that are sometimes infected with human papillomavirus (HPV). We studied retrospectively paraffin-embedded sections of 11 samples of cutaneous BD and 6 samples of genital BP from the general population for HPV infection and filaggrin expression. Using in situ hybridization with biotinylated probes of HPV types 1, 2, 5, 6, 11, 16, and 18, under stringent and/or non-stringent conditions and a streptavidin-alkaline-phosphatase complex for hybrid detection, HPV DNA was detected in 6/17 cases (5 BD and 1 BP). Positive nuclei were located in intermediate or upper epithelial cell layers. HPV 16 was found in 2 cases of BD but associated either with HPV 2 or 18. Three additional lesions reacted only under non-stringent conditions; HPV could not be typed with the probes used. The positive case of BP reacted with the four probe types 1, 2, 16, 18 and was negative with HPV 6 or 11. Viral antigen was not detected by indirect immunofluorescence with a rabbit antiserum directed to group-specific viral capsid antigen. Differentiation disorders were observed in the intermediate and upper cell layers of these specimens, as shown by a reduced expression of filaggrin/profilaggrin, a marker of terminal differentiation, in extragenital BD (7/11 cases), and an increased expression in genital BP (4/5 cases) although viral DNA was not always detectable. This study shows that in situ hybridization is a valuable technique for HPV DNA detection and its typing in BD and BP lesions on deparaffinized sections. The positive nuclei were located in the cell layers that exhibited abnormal expression of differentiation. There is no relation between the HPV infecting type and the filaggrin expression.

Abstract
In situ hybridization was mainly used for typing human papillomavirus (HPV) in paraffin-embedded or frozen sections under stringent conditions (SC). We tested 5 different conditions of stringency with biotinylated HPV 1, 2, 16 and 18 probes on 3 cell lines (Sihà and CaSki with HPV16, HeLa with HPV18) by varying the concentration of formamide in the hybridization mixture and washings in order to determine the stringency conditions to be used to assess the presence of HPV and its typing: A-low stringency, hybridization at 35 degrees C below the melting temperature of DNA (Tm-35 degrees C) and washings without formamide; B-low stringency, hybridization and washings at Tm-35 degrees C; C-medium stringency, hybridization at Tm-35 degrees C and washings at Tm-12 degrees C; D-high stringency, hybridization at Tm-12 degrees C and washing without formamide; E-very high stringency, hybridization and washings at -12 degrees C. This study showed that HPV typing required a high stringency. On the contrary, under non stringent conditions (NSC), each cell line was positive with the heterologous probes. When 3 to 5 stringency conditions were assayed on 4 frozen samples, similar results were obtained. Typing required high stringency conditions whereas NSC allowed HPV detection. Furthermore, this study demonstrated the specificity of the reaction in lesions positive with more than one type. Stringent (Tm-12 degrees C) and non stringent (Tm-35 degrees C) conditions of hybridization were further applied to 57 biopsy sections (17 frozen and 40 paraffin-embedded specimens) from typical wart lesions and lesions suspected of HPV.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We compared nine different techniques for the detection of biotinylated DNA-DNA HPV hybrids on HeLa cells with 10-50 copies of HPV 18 DNA per cell. CaSki cells with 600 copies of HPV 16 DNA per cell and tissue sections from frozen or paraffin-embedded biopsy specimens. The cell samples were either cell deposits or cytocentrifuged or cultured slides. In most cases, the samples (cell deposits and tissue sections) were denatured with hybridization mixture prepared under stringent conditions (Tm = -17 degrees C) containing biotinylated DNA probes (cloned HPV types 1, 2, 6, 11, 16 and 18), at 90 degrees C for 10 min. In other cases (cytocentrifuged or cultured cells), the denaturation was performed by HCl hydrolysis and mild heating at 50 degrees C; the probes were denatured separately by heating. All the samples were further incubated overnight at 37 degrees C. For HPV DNA detection, three amplification levels were used on cell deposits. Only the techniques involving a three-step reaction (a rabbit anti-biotin antibody - a biotinylated goat anti-rabbit antibody - a complex of streptavidin-alkaline phosphatase or streptavidin-gold or streptavidin-fluorescein) gave satisfactory results, on both cell lines. With the one step reaction (an avidin-horseradish peroxidase, or streptavidin-alkaline phosphatase or streptavidin-fluorescein complex), no labeling of HeLa cells was observed with any of the HPV probes, including HPV 18. The techniques involving four steps (avidin or streptavidin - anti-avidin goat antibody or anti-streptavidin rabbit antibody - a biotinylated anti-goat (or anti-rabbit) antibody - a complex of avidin-biotin-peroxidase or streptavidin-biotin-alkaline phosphatase or streptavidin-biotin-horseradish peroxidase) resulted in high background on both cell lines. For the reproducible detection of low copy number of HPV DNA (less than 50 copies) such as occur in HeLa cells our data suggested that the three-step technique with the streptavidin-alkaline phosphatase complex was the method of choice. The most intense labeling was always obtained with cell deposits and the technique was successfully applied to frozen and paraffin-embedded tissue sections from typical warts.
