Verrucous carcinoma, because of its oftentimes unusual clinical appearance, may be misdiagnosed if there is not good communication between the surgeon and the pathologist. We have reviewed our series of 20 cases of verrucous carcinoma from 1964 through 1974 and have analyzed the results of our therapy. We have concluded that verrucous carcinoma is a slow-growing, locally invasive lesion that does not metastasize to the cervical lymph nodes. Radiation therapy does not seem to be an effective method of treatment; the recurrence rate is high. Conservative laryngeal surgery is the preferred method of treatment in these patients and should prevent loss of life and spare laryngeal function.

Twelve cases of verrucous carcinoma of the orofacial region were reviewed for their clinical and pathological characteristics. Verrucous carcinoma made 3.5% of all primary epidermoid carcinoma observed during the period of investigation. The tumour occurred chiefly in older patients (from 25 to 81 years, mean age 57.5) and more often in males than in females (9 males: 3 females). The most common site of occurrence was the vermilion surface of the lower lip (seven cases). Macroscopic appearance of lesions was reported as exophytic, warty, and white. Microscopically, the thickened epithelium was well differentiated and stratification was preserved. Rete pegs of carcinoma were broad and blunt; they also appeared to "puch" into underlying tissues. Basement membrane appeared to be intact. Cells of tumours were displayed, and histologic features of the spectrum were generally associated with viral modification. The prognosis in verrucous carcinoma is very good, because of the absence of metastases. Radiotherapy should not be used, since not only local recurrence is common, but also anaplastic changes may occur with corresponding aggressive behaviour and metastasis.

Verrucous squamous cell carcinoma is a rare type of well-differentiated squamous cell carcinoma with a characteristic morphologic appearance and specific clinical behavior. It has been claimed that this tumor may undergo dedifferentiation after radiotherapy; this will result in a more aggressive behavior. From 1968 to 1980, we have diagnosed and treated 569 squamous cell carcinomas of the larynx. Fourteen of them were reported to exhibit verrucous features macroscopically. These tumors were histopathologically reexamined. All 569 cases were stratified with regard to tumor stage (less than or equal to T2 N0 M0) and treatment (irradiation). Six patients of 340 were then diagnosed as having verrucous squamous cell carcinomas, according to the Ackerman criteria. The patients were followed for at least 5 years and regional metastases of poorly differentiated carcinoma developed in at least two patients in the verrucous carcinoma group within 2 1/2 years after full-dose irradiation. Among the patients with nonverrucous carcinoma, this frequency was estimated to be 3%. This study provides evidence that metastatic spread that occurs after irradiation is approximately 10 times more frequent (p less than 0.05) for T1-2 laryngeal verrucous carcinomas, as compared to the common type of squamous cell carcinoma.

Verrucous carcinoma of the esophagus is a rare variant of squamous cell carcinoma with a slow, non-invasive growth without formation of metastases. Until today, only 8 cases of verrucous carcinoma of the esophagus have been reported in the literature. All of these tumours showed infiltration of adjacent mediastinal structures or even lymph node metastases. In therefore seems doubtful, wether these tumours were really verrucous carcinomas rather than squamous cell carcinomas of the papillary type. Several authors have questioned the malignant nature of these tumors recently. We report a case of a verrucous lesion of the esophagus the course of which we were able to observe over a period of several years. Transhiatal esophagectomy without thoracotomy is recommended as treatment of choice for verrucous tumours of the esophagus.

Verrucous carcinoma (Ackerman's tumor) is a low-grade malignant lesion with distinct clinical and pathologic features, distinguishing it from other well-differentiated squamous cell carcinomas. Much of the confusion surrounding its natural history, response to therapy, and anaplastic transformation may be ascribed to the failure of critically reviewing accepted diagnostic criteria. A series of 44 patients with verrucous carcinoma of the larynx is presented, 18 of these being updated results of previously reported patients. Ackerman's tumor, although not radioresistant, seems less radiosensitive than ordinary squamous cell carcinoma. The tumor's rounded, pushing margins and inability to metastasize would seem to favor endoscopic removal, saving partial laryngectomy procedures for those lesions that cannot be managed endoscopically. Extensive lesions that would require total laryngectomy for complete removal of the tumor should be treated by primary radiotherapy. It is our belief that total laryngectomy should only be performed in large lesions that fail to respond to radiotherapy and whenever medical considerations preclude partial laryngectomy procedures.

Verrucous carcinoma is a variant of epidermoid carcinoma with distinctive clinical and pathological features. The diagnosis is often difficult. To date, 20 verrucous carcinomas involving the vulva have been reported in the literature. Metastases to the inguino-femoral lymph nodes have not been described. The treatment of choice is wide local excision. Clinical features, histological findings, and therapy are discussed.

Verrucous carcinoma of the bladder unassociated with bilharzial cystitis is rare with only 6 cases reported to date. Verrucous carcinoma of the bladder, like that involving the cervix, vagina, oral cavity, perineum and lower extremities, may invade surrounding structures but remain surgically curable. Although it is similar to condyloma acuminatum, verrucous carcinoma is considered malignant because of its invasive growth pattern and it should be treated accordingly. However, no evidence of metastases has been noted to date. To our knowledge we report the first case of extravesical extension of verrucous carcinoma of the bladder that was treated successfully by surgical removal.

Verrucous carcinoma of the penis (Buschke-Lowenstein tumor) is a rare variant of squamous cell carcinoma which has been reported to have limited potential for metastatic disease. We report on 2 patients who presented with locally advanced disease after prolonged intervals of neglect. In both cases, the disease was locally aggressive with extensive tissue destruction. In 1 patient, after failure to achieve tumor control with repeated aggressive surgical excision, systemic chemotherapy using bleomycin, cisplatin, methotrexate, and leucovorin led to a complete pathologic response. We believe this is the first reported case in which systemic chemotherapy has been used to successfully treat verrucous carcinoma of the penis. Surgical excision alone was successful in achieving local disease control in the second patient.

Verrucous carcinoma (VC) of the esophagus is a rare variant of squamous cell carcinoma and only 20 cases have so far been reported in the international literature. The neoplasm is usually highly differentiated, presents a slow growth pattern with invasion of surrounding organs rather than blood-borne metastases. Recently, a causative role of human papillomavirus (HPV) has been hypothesized. The case of a patient affected with locally advanced VC of the esophagus and treated by means of local antiviral therapy is reported. A 41-year-old male patient was admitted to our institution for persistent atypical thoracic pain. The imaging techniques (thoracic and abdominal CT scans; upper GI endoscopy; hydrosoluble contrast swallow; endoscopic US) revealed a cauliflower-like protruding esophageal mass, active mucosal mycosis, multiple ulcerations of the distal esophagus, as well as 2 broncho-esophageal fistulas. The neoplasm extended beyond the esophageal wall, infiltrating surrounding cervical and mediastinal organs and the patient presented with secondary esophageal achalasia and right bilobar pneumonia. The histologic specimen was consistent with VC of the esophagus and the presence of HPV infection was detected by means of qualitative PCR assay. The patient was deemed not fit for surgery and a local antiviral treatment with hydroxy-phosphonyl-methoxypropyl-cytosine 5 mg/kg a week was started. After initial response to treatment, the patient presented with sudden progression leading to further broncho-esophageal fistula treated with endoscopic stent placement and ultimate death 6 months after referral to our center. In keeping with international data, our case confirms that esophageal VC has a highly unfavorable outcome, despite its high degree of differentiation and slow growth pattern. The long natural history, the lack of specific symptoms and the presence of coexisting esophageal diseases delay the diagnosis and account for the local advancement of this malignancy. Surgery is the option of choice for early stage lesions and advanced VC does not seem to benefit from current chemotherapeutic regimens. The causative role of HPV and the advancements of molecular pharmacology might allow for effective treatment in high-risk patients.
