Invasive Squamous Cell Carcinoma of the Oral Mucosa Associated with HPV Type 53

A 77-year old man presented with a fungating mass on the oral mucosa and lip, which had an irregular margin. An incisional biopsy of the mass revealed an invasive squamous cell carcinoma. PCR analysis detected HPV DNA in the biopsy specimen. The HPV type was determined as HPV-53 by direct cycle sequencing. This is the first report of HPV-53 in an oral malignant tumor.

Expression of p63 and p53 Proteins in Premalignant Lesions and Invasive Squamous Cell Carcinomas of the Uterine Cervix / 대한산부인과학회잡지

OBJECTIVE: p63 is a member of the p53 gene family. The main aim of this study was to compare p63 and p53 expression in precancerous lesions and invasive squamous cell carcinoma of the uterine cervix. METHODS: Total 81 formalin-fixed, paraffin-embedded sections of low-grade squamous intraepithelial lesion (22 cases), high-grade squamous intraepithelial lesion (42 cases) and invasive squamous cell carcinomas (17 cases) in the uterine cervix were stained by immunohistochemistry for expression of p63, p53 and topoisomerase II-alpha. RESULTS: p63 was statistically significant higher immunoreactivity according to progression of uterine cervical squamous lesions, but p53 was not significant. No statistical correlation was found between p63 and p53. Topoisomerase II-alpha index was statistically significant higher according to increase of p63 expression. CONCLUSION: These findings suggest that the expression of p63 protein may play a roles in progression and proliferative activities of the uterine cervical squamous lesions.

Expression of c-erbB-2 Oncoprotein and DNA Topoisomerase II-alpha in Premalignant Lesions and Invasive Squamous Cell Carcinomas of the Uterine Cervix / 대한산부인과학회잡지

OBJECTIVE: The relationship was studied between expression of c-erbB-2 oncoprotein and topoisomerase II-alpha as proliferating marker in precancerous lesions and invasive squamous carcinomas of the uterine cervix. METHODS: Total 81 formalin-fixed, paraffin-embedded sections of low-grade intrasquamous lesion (22 cases), high-grade intraepithelial lesions (42 cases) and invasive squamous cell carcinomas (17 cases) in the uterine cervix were stained by immunohistochemistry for expression of the c-erbB-2 oncoprotein and topoisomerase II-alpha. RESULTS: The expression of c-erbB-2 oncoprotein and staining index (mean+/-S.D) of topoisomerase II-alpha were statistically significant between precancerous lesions and invasive carcinoma. The expression of c-erbB-2 oncoprotein has correlation with staining index (mean+/-S.D) of topoisomerase II-alpha. CONCLUSION: There results suggest that the expression of c-erbB-2 protein has relationship with progression of squamous lesions and topoisomerase II-alpha is an useful proliferating marker in the uterine cervix. And, the expression of c-erbB-2 protein has correlation with expression of topoisomerase II-alpha.

Adenoid Basal Carcinoma Associated with Invasive Squamous Cell Carcinoma of Uterine Cervix: A case report

Adenoid basal carcinoma of the uterine cervix is a rare neoplasm that accounts for less than 1% of cervical adenocarcinomas. Though it has been confused with adenoid cystic carcinoma, it is now distinctly recognized by better prognosis and different histologic and immunohistochemical findings. We have experienced a case of adenoid basal carcinoma associated with invasive squamous cell carcinoma of the uterine cervix in a 52-year-old woman. The tumor was composed of small, round to oval nests of basaloid cells with peripheral palisading. Some of the nests showed central cystic spaces, or cribriform pattern, and central squamous differentiation with cytological atypia. Invasive squamous cell carcinoma was located adjacent to the adenoid basal carcinoma without any transition between these two lesions. Immunohistochemically, the tumor cells disclosed positive staining for cytokeratin, but negative reaction for CEA, EMA, and S-100 protein.
