1/193. Human papillomavirus types 16 and 39 in a vulval carcinoma occurring in a woman with Hailey-Hailey disease.

    A woman with Hailey-Hailey disease, suffering from carcinoma of the vulva, was examined by histology and for the presence of human papillomavirus (HPV) DNA by polymerase chain reaction (PCR) and in situ hybridization. Our diagnosis by histological examination revealed the vulval carcinoma to be a squamous cell carcinoma (SCC), adjacent to lesions of Hailey-Hailey disease and severe dysplasia/carcinoma in situ [vulval intraepithelial neoplasia (VIN) III]. The PCR with consensus primers for the L1 region (L1-PCR) successfully amplified HPV DNA using total DNA extracted from formalin-fixed and paraffin-embedded tissue specimens. Restriction fragment length polymorphism analysis and sequencing of L1-PCR products revealed HPV types 16 and 39. HPV 16-specific primers for the E6 region identified HPV 16 DNA. in situ hybridization analysis with biotinylated HPV 16 and 39 dna probes revealed the presence of the HPV 39 genome in the nuclei of the tumour cells in the SCC. These results indicate that HPV 16 and 39 are associated with lesions in vulval carcinoma. Regarding the patient's susceptibility to infection in the case of Hailey-Hailey disease, there is a possibility that HPV was inoculated into the lesions of Hailey-Hailey disease and induced those of VIN III and SCC.

2/193. erythroplasia of Queyrat treated by topical aminolaevulinic acid photodynamic therapy.

    erythroplasia of Queyrat (EQ) is an intraepithelial carcinoma in situ affecting the mucosal surfaces of the penis, with a significant risk of invasion and metastasis. Treatment is often difficult and is associated with significant recurrence rates. Topical 5-aminolaevulinic acid (ALA) photodynamic therapy (PDT) combines a photosensitizer precursor and visible light to produce a photodynamic effect. It has been used successfully to treat benign, premalignant and malignant skin diseases. We present four patients with EQ who have been treated by topical ALA PDT. Of two patients with limited disease one has achieved a long-term complete response (36 months) and the other developed a recurrence at 18 months after a complete response. Two further patients with more extensive disease achieved a significant improvement, allowing easier treatment by laser vaporization. Although topical ALA PDT offers the advantages of tumour specificity, preservation of function and a good cosmetic result, more extensive EQ appears less responsive to this new therapeutic modality using current treatment parameters.

3/193. Squamous cell carcinoma of the penis arising on lichen sclerosus et atrophicus.

    Squamous cell carcinoma of the penis arising on lichen sclerosus et atrophicus is rarely reported. A case is described in a 63-year-old man who had been diagnosed of lichen sclerosus et atrophicus 3 years before. The previously reported cases, the association of these diseases in women and men, and the possible pathogenesis are discussed.

4/193. Discussing disease progression and end-of-life decisions.

    Because most patients now want to know the truth about their diagnosis and prognosis, the ability to discuss the cancer diagnosis, disease recurrence, or treatment failure, and to solicit patients' views about resuscitation or hospice care, are important verbal skills for oncologists and other oncology health care providers. Moreover, the ability to clearly articulate a treatment plan or elicit patient preferences for treatment are a prerequisite to informed consent. Despite these imperatives, clinicians do not routinely receive training in key communication skills that could enable them to accomplish these tasks. A body of literature is available, however, that identifies communication strategies that can (1) facilitate the establishment of a close rapport with the patient, (2) identify the patient's information preferences, (3) ensure comprehension of key knowledge and information, (4) address the patient's emotions in a supportive fashion, (5) elicit the patient's key concerns, and (6) involve the patient in the treatment plan. In this article, we use dialogues between a physician and a hypothetical patient with advanced ovarian cancer to illustrate how communication techniques can be applied to accomplish these goals. We identify important benefits of the use of these techniques for both the physician and patient, and pose several questions regarding the training of physicians in this area.

5/193. Positive impact on surgical treatment for asymptomatic patients with esophageal carcinoma.

    BACKGROUND/AIMS: The prognosis of patients with esophageal carcinoma remains unsatisfactory. The purpose of this study was to clarify the clinicopathologic characteristics of asymptomatic patients. METHODOLOGY: We retrospectively compared 78 cases of asymptomatic esophageal carcinoma (AEC) with 341 cases of symptomatic esophageal carcinoma (SEC). RESULTS: In 47 of 78 patients with AEC, the tumors were discovered by mass screening and in 31 patents by follow-up examination for other disease. Nearly 70% of the patients with AEC had a carcinoma in situ (Tis) or T1 tumor, whereas nearly 70% of the patients with SEC had T3 or T4 tumors. The incidences of lymph node metastasis, lymphatic invasion and vascular invasion were significantly lower in patients with AEC than in those with SEC. The 5-year survival rate in AEC and SEC were 59.3% and 22.9%, respectively. With regard to the cause of death, 26.8% (11/41) of patients with AEC and 59.9% (166/277) of patients with SEC died of esophageal carcinoma. CONCLUSIONS: In order to improve the prognosis of esophageal carcinoma, an effort should be made to detect early esophageal carcinoma among patients at risk for tumors when they are still asymptomatic.

6/193. Treatment of conjunctival intraepithelial neoplasia with topical drops of mitomycin C.

    PURPOSE: To evaluate the efficacy and risks of complications of topical mitomycin C (MMC) for small-size conjunctival intraepithelial neoplasia (CIN). methods: Eight patients with clinically diagnosed CIN <8 mm were included in the study. patients received topical drops of MMC, 0.02-0.04%, 4 times daily for 14 days. retreatment was done when lesions were not eliminated or recurred after the first treatment. RESULTS: Three patients remained disease free after one course of MMC application. retreatment was done in four patients because of lesions that decreased in size but were not eliminated, and for regrowth in one case. After retreatment, the lesions were eradicated in four patients, whereas in one patient, the treatment failed, and the lesion was surgically excised. The complications of MMC use included mild conjunctival hyperemia in two patients and mild allergy in one patient, which resolved after discontinuation of the treatment. CONCLUSION: Application of topical MMC is an effective treatment for most but not all cases of small-size CIN.

7/193. Sebaceous carcinoma of the breast.

    We report on a rare distinctive variant of infiltrating ductal carcinoma characterized by sebaceous differentiation of tumor cells. The neoplasm was identified in a lumpectomy specimen from a 45-year-old woman with extensive metastatic disease. In addition to conventional in situ and invasive ductal components, approximately half of the tumor cells exhibited a phenotype resembling tumors of the sebaceous skin appendage with coarsely vacuolated cytoplasm and peripherally displaced nuclei. The sebaceous moiety was also present in the distant metastatic deposits. There was no evidence of mucin production by tumor cells. Ultrastructurally, empty-appearing non-membrane bound vacuoles attested to the sebaceous cells' lipid content. The immunoprofile of the lesion included positivity for cytokeratin and epithelial membrane antigen. vimentin, S100 protein and carcinoembryonic antigen were not expressed. Most tumor cell nuclei reacted with antibodies to oestrogen and progesterone receptors but failed to show overexpression of the HER2/neu protein. The MIB-1 labeling index averaged 16%. At variance with sebaceous breast carcinomas on record, the present case is notable for its prolonged clinical course.

8/193. Squamous cell carcinoma arising in Hailey-Hailey disease of the vulva.

    A 61-year-old woman, who was known to have Hailey-Hailey disease, presented with increasing vulval soreness. biopsy showed vulval intraepithelial neoplasia (VIN) 3 and subsequent histology from a vulvectomy specimen showed extensive VIN with early invasive squamous cell carcinoma. This may be another example of chronic inflammation of the vulval area leading to the development of squamous cell carcinoma. However, in this case, chronic human papillomavirus may also have played a part, leading to VIN and reactivation of the Hailey-Hailey disease. We can find no previous reports of squamous cell carcinoma developing in the setting of Hailey-Hailey disease.

9/193. Recurrent invasive adenocarcinoma after hysterectomy for cervical adenocarcinoma in situ.

    BACKGROUND: Unlike its squamous counterpart, therapy for cervical adenocarcinoma in situ with positive endocervical cone margin remains controversial. CASE: A 52-year-old gravida 2, para 1,0,1,1, presented with vaginal bleeding. Gynecologic history was significant for cervical cold knife conization with a positive endocervical margin and endocervical curettage with atypical endocervical cells. Repeat cone biopsy was considered unsafe given the large initial cone specimen. An extrafascial hysterectomy was performed 5 weeks later and pathology confirmed a disease-free cervix. Pap smear performed 1 year later was interpreted as recurrent adenocarcinoma but later downgraded to inflammation. Inspection and random biopsies of the vaginal cuff revealed only inflammation. Two subsequent Pap smears also returned inflammation. Seventeen months after the hysterectomy physical examination revealed a 2 x 3-cm smooth mass at the vaginal cuff. biopsy revealed invasive adenocarcinoma. The patient underwent an upper vaginectomy followed by postoperative pelvic radiation. CONCLUSION: This case suggests that despite extrafascial hysterectomy for presumed adenocarcinoma in situ of the cervix, a residual focus could remain and present later as invasive adenocarcinoma.

10/193. Radical excision of multifocal anal intraepithelial neoplasia: report of a case.

    PURPOSE: The aim of this study was to describe the technique of radical excision of multifocal anal intraepithelial neoplasia and discuss controversial issues surrounding the management of this condition. METHOD: We describe the case of a 31-year-old female with previous vulval warts, vulval squamous carcinoma, and recent immunosuppression who had widespread anal intraepithelial neoplasia excised, and the resulting defect was split-skin grafted, including the anal canal. RESULTS: Excision and split-skin grafting was successful in removing the disease and left a satisfactory cosmetic and functional result. CONCLUSION: Diffuse, high-grade, anal intraepithelial neoplasia is rare. Excision of these lesions remains controversial but may be the best option.
