1/104. Verrucous carcinoma of the vulva in a patient infected with the human immunodeficiency virus.

    Verrucous carcinomas of the vulva are rare and have not been reported in women infected with the human immunodeficiency virus. We present such a case in a 32-year-old woman characterized by bladder involvement that failed therapy with 13-cis-retinoic acid and interferon-alpha and required anterior exenteration. ( info)

2/104. Pelvic abscess with fistula to the abdominal wall due to verrucous carcinoma.

    The case report of a 38-year-old woman with a pelvic abscess resulting from verrucous carcinoma of the uterine cervix is presented. This case is remarkable because the abscess formed a fistula through the anterior abdominal wall and because there was no visible lesion on the cervix. The patient underwent a total abdominal hysterectomy, left salpingectomy, fistulectomy, and removal of the abscess. diagnosis was made on pathologic examination of the extirpated specimen. Genital tract verrucous carcinoma and genitocutaneous fistulae are reviewed. ( info)

3/104. Cervical verrucous carcinoma involving endometrium. Case report.

    A case report of verrucous carcinoma of the cervix is presented. Verrucous carcinoma is a rare variant of squamous cell carcinoma with distinct clinical and histopathologic features, with a favorable prognosis. A 32-year-old woman had an abdominal hysterectomy with bilateral ovary transposition. Intravaginal brachytherapy using cesium 137 in a total dose of 60 Gy 0.5 cm from the vaginal layer was performed. Five year disease-free follow-up was observed. Macro- and microscopic examination of the tissue after hysterectomy was performed. The full thickness of the tumor is necessary for histopathological assessment. The cytology or superficial and simple biopsy may be misdiagnosed. The differentiating diagnosis among condyloma acuminata, verrucous carcinoma and invasive squamous cell carcinoma was analysed. ( info)

4/104. Proliferative verrucous leukoplakia: report of two cases and a discussion of clinicopathology.

    Proliferative verrucous leukoplakia (PVL) is a recently delineated but poorly recognized form of multifocal leukoplakia that is premalignant and of unproven origin. PVL generally presents as a simple benign form of hyperkeratosis that tends to spread and become diffuse. Although slow-growing, the disease is persistent and irreversible. Clinically, PVL often presents as an exophytic wart-like form of leukoplakia that appears to be resistant to nearly all forms of therapy. PVL of the oral cavity is best-defined as a continuum of oral epithelial disease with hyperkeratosis at one end of a clinical and microscopic spectrum and verrucous carcinoma or squamous cell carcinoma at the other. The microscopic findings associated with PVL are dependent on the stage of the disease and the adequacy of the biopsy. Microscopic findings can be markedly variable. PVL is a clinicopathologic disorder that includes the microscopic entity known as verrucous hyperplasia as a component of its histopathologic progression. This article reports on two cases of PVL, describes the clinicopathology of the disease process, and presents therapeutic and etiologic considerations. ( info)

5/104. Verrucous carcinoma of the female breast.

    Verrucous carcinoma is a rare skin malignancy of squamous cell origin. It is characterised by negligible cellular atypia and a low mitotic rate. These are reflected in slow locally invasive behaviour and very infrequent metastatic spread. The tumour is also recognised in oral and anogenital sites. Cutaneous lesions present most commonly on the sole of the foot. We report a unique case occurring in the female breast. ( info)

6/104. Invasive verrucous carcinoma: a temporal bone histopathology report.

    Only nine cases of primary verrucous carcinoma of the temporal bone have been reported in the English literature. We describe histopathologic findings in a 78-year-old man dying of intracranial complications of primary verrucous carcinoma of the external auditory canal. Following autopsy the temporal bone was prepared for light microscopic examination. The temporal bone was serially sectioned horizontally after fixation, decalcification, and embedding, and each 10th section was stained with hematoxylin and eosin and examined by light microscopy. The carcinoma originated from the external auditory canal, infiltrating the mastoid cavity, the middle ear, tissue adjacent to the internal carotid artery, and the posterior cranial fossa, where it invaded the right cerebellum and produced an abscess. The labyrinth and internal auditory canal were not infiltrated. Metastasis to lymph nodes or distant sites was not identified. In the present case, the verrucous carcinoma originating from the external auditory canal extended into the posterior cranial fossa, while it did not invade the membranous labyrinth. ( info)

7/104. Metachronous carcinoma of the vulva and fallopian tube.

    BACKGROUND: Metachronous carcinoma of the vulva and fallopian tube is an unusual co-occurrence of gynecological malignancies. A report of such a case that developed and recurred over a 7-year period is presented. CASE: A 53-year-old G3P3 female presented with a verrucous carcinoma of the vulva and a serous papillary adenocarcinoma of the left fallopian tube metachronously. To investigate a possible association between the co-occurrence of the rare neoplasms and factors associated with multiple gynecological malignancies, we analyzed the status of human papillomavirus infection and dna mismatch repair deficiency as indicated by microsatellite instability. All samples analyzed were negative for these factors. CONCLUSION: The present results support the possibility that metachronous carcinomas of the vulva and fallopian tube involve unknown etiological factors or arise independently. ( info)

8/104. Warty (condylomatous) squamous cell carcinoma of the penis: a report of 11 cases and proposed classification of 'verruciform' penile tumors.

    Within the spectrum of penile squamous cell carcinomas, those that we descriptively refer to collectively as the "verruciform" lesions are particularly difficult to subclassify. In a review of 50 such tumors, we found 11 distinctive neoplasms with condylomatous features conforming to the appearance of so-called "warty (condylomatous) carcinoma." The average patient age was 55 years and the average duration of disease was 19 months. The primary tumor involved multiple anatomic sites (glans, coronal sulcus, and foreskin) in seven cases and a single site (glans or foreskin) in four cases. Grossly, white to gray cauliflower-like tumors typically measuring approximately 5 cm were noted. Histologically the tumors were mainly papillomatous with acanthosis and hyperkeratosis. The papillae had prominent fibrovascular cores. The most conspicuous microscopic findings were striking nuclear atypia of koilocytotic type and clear cytoplasm. The interface between tumor and stroma was irregular in the majority of cases; deep invasion of corpus cavernosum was noted in five cases. The differential diagnosis included verrucous carcinoma, low-grade papillary squamous cell carcinoma, not otherwise specified, and giant condyloma acuminatum. Among other differences, the first two lesions show no koilocytotic changes and the last lacks malignant features and irregular stromal invasion. Metastatic spread occurred in two patients; both are alive with evidence of recurrent disease 12 and 72 months after initial diagnosis. A third patient was alive with recurrent disease 12 months after diagnosis. Five patients were free of disease 8, 12, 24, 52, and 108 months after diagnosis. Three patients were lost to follow up. Warty (condylomatous) carcinomas of the penis are morphologically distinctive verruciform neoplasms with features of human papillomavirus-related lesions and should be distinguished from other verruciform tumors so that differences in behavior, if any, between these tumors will become established.

9/104. Verrucous carcinoma of the esophagus completely resected by endoscopy.

    Verrucous carcinoma of the esophagus is a very rare esophageal cancer. We present a case of verrucous carcinoma of the esophagus, the 14th such case reported. In contrast to the previous cases, our patient had no symptoms and did not have a history of severe or repeated injury of the esophagus. The patient was completely resected by endoscopy and was well after 3 yr of follow-up, without recurrence of the disease. ( info)

10/104. Verrucous carcinoma occurring in a lesion of oral lichen planus.

    Verrucous carcinoma of the oral cavity is relatively rare. Well-documented associations include human papillomavirus and carcinogens such as tobacco. Less well understood is the association with chronic inflammation, such as seen in lichen planus. Verrucous carcinoma has previously been described occurring in lesions of lichen planus of the foot and penis. We report the first case, to our knowledge, of verrucous carcinoma occurring in a lesion of oral lichen planus. ( info)
