1/31. Squamous cell papillomatosis of esophagus following placement of a self-expanding metal stent.

    The esophageal self-expanding metal stent has gained widespread acceptance for the management of tracheoesophageal fistulas and the palliative management of malignant esophageal strictures. The complications associated with its use can be classified as either immediate or delayed. The most frequent delayed complications include tumor ingrowth, stent migration, reflux of gastric contents, bleeding, and perforation. This case report illustrates an otherwise unrecognized delayed complication of a self-expanding metal stent. Near complete ingrowth of the stent by squamous mucosal hyperplasia occurred within six weeks of the metal stent's placement. This finding supports the hypothesis that mucosal injury and regeneration underlies the etiology of esophageal squamous cell papilloma formation.

3/31. Squamous papilloma of the esophagus associated with the human papillomavirus.

    Squamous cell papilloma of the esophagus is a rare lesion involving less than 60 case reports worldwide. These lesions are generally asymptomatic but may at times grow and spread rapidly. One fatality, a result of massive dissemination, has been reported. Until recently, human papillomavirus had not been identified in association with esophageal papillomas. A second case, to the authors' knowledge, of esophageal papillomas associated with human papillomavirus is reported. The virus has been previously shown to be associated with abnormal squamous epithelium in and adjacent to esophageal carcinoma. The virus was identified from biopsy specimens obtained at endoscopy using dna in situ hybridization techniques. The strain of human papillomavirus identified is similar to those found in the oropharynx and genital tract, raising the possibility of sexual transmission. This case also differs from the previous case report involving the human papillomavirus because of the patient's benign clinical course. Our case serves to highlight differences that are perhaps unique to the human papillomavirus. Multiple papillomas found in a proximal location within the esophagus seem to favor involvement of the human papillomavirus. Isolated lesions located distally appear more characteristic of chronic gastroesophageal reflux as an etiology. The syndrome of squamous cell papillomas involving the esophagus is reviewed in the article.

4/31. Photodynamic therapy and endoscopic metal stent placement for esophageal papillomatosis associated with squamous cell carcinoma.

    Esophageal squamous papillomatosis is a rare condition associated with human papilloma virus infection and has been complicated by the development of squamous cell carcinoma. Photodynamic therapy using porfimer sodium has been used for the treatment of esophageal cancer but has not been utilized in the treatment of esophageal squamous papillomatosis. We report here the first case of papillomatosis and obstructing squamous cell carcinoma of the esophagus palliated with porfimer sodium photodynamic therapy indicating successful photosensitizer uptake in papilloma-laden tissue. Extensive debulking of papilloma and tumor allowed esophageal recanalization and placement of a self-expanding metal stent for long-term dysphagia palliation. This unique case highlights the combined use of endoscopic techniques for optimal treatment results.

5/31. Carcinoma cuniculatum of the esophagus.

    AIMS: Extremely well-differentiated squamous cell carcinoma with the features of so-called carcinoma cuniculatum (CC) is a rare neoplasm. We describe the clinicopathologic findings of the first 2 cases of CC of the esophagus. methods AND RESULTS: Two elderly men presented with symptoms and clinical signs of esophageal malignancy. Repeated endoscopic biopsies of their esophageal tumors were inconclusive. Resection revealed CC of the esophagogastric junction in both cases. The tumors extended into the adventitia but no lymph node metastases were present. in situ hybridization for human papillomavirus HPV subtypes was negative. CONCLUSION: Carcinoma cuniculatum is reported for the first time in the esophagus. The diagnosis of this tumor variant is difficult by means of cytological examination or by endoscopic biopsies alone. Carcinoma cuniculatum in this location shows biologic features similar to verrucous carcinoma (deep penetration, no lymph nodes metastases, and location at one end of the esophagus). No evidence of human papillomavirus could be demonstrated.

6/31. Primary glomangioma of the esophagus mimicking esophageal papilloma.

    We report a case of glomangioma of the esophagus in a 28-year-old woman who presented with a 3-year history of vague discomfort, pain and heat in the neck. At initial gross examination, the tumor mimicked an esophageal papilloma. The resected esophageal specimen contained a polypoid, whitish-gray mass, which measured 3 cm in maximum diameter. Microscopically the tumor consisted of loose fibrovascular stroma heavily infiltrated with mononuclear inflammatory cells and covered with focally hyperkeratotic, parakeratotic and acanthotic squamous epithelium without atypia. In the deeper area immediately above the true muscular layer of the esophageal wall, microscopical examination revealed the neoplasm consisting of numerous, small-to-medium branched vessels covered by regular endothelium and filled with erythrocytes. The loose stroma around the vessels contained poorly circumscribed nests of small, round to oval cells with a uniform appearance. Immunohistochemically, the tumor cells were immunoreactive for smooth muscle actin and vimentin and non-immunoreactive for CD34, CD117, desmin, pan-cytokeratin, synaptophisin, neuron-specific enolase and S-100 protein. Despite its bland histology, the infiltrative growth pattern was suggestive of aggressive behavior; thus, an appropriate clinical follow-up was recommended. An accurate diagnosis and an understanding of the behavior of these rare tumors, especially in an unusual location, are crucial to their management and clinical outcome.

7/31. Human papilloma virus type 11 in a fatal case of esophageal and bronchial papillomatosis.

    We report a case of an apparently healthy 27-year-old man with a fatal course of papillomatosis, originating in the distal part of the esophagus and spreading into the main and intermediate bronchus. Human papillomavirus type 11, usually associated with juvenile laryngeal papillomatosis and genital condyloma acuminatum, was detected in the papillomas. In spite of treatment with CO2-laser evaporation of the papillomas, and with systemic as well as topical interferon, VP-16 and bleomycin, the papillomatosis progressed relentlessly during almost 2 years, and finally caused the death of the patient. We have no explanation for the malignant course of wart virus infection in this young man.

8/31. Squamous papilloma of the esophagus: a case report and review of the literature.

    A case of squamous cell papilloma of the esophagus in a 70-yr-old white woman is reported. The literature is reviewed, summarized, and tabulated. This study found that the average age of a person with a squamous cell papilloma of the esophagus was 51.5 yr, with an associated male:female ratio of 1.8:1 (39M:22F). Additionally, most squamous papillomas were single (52) rather than multiple (9), most were located in the distal one-third of the esophagus (41), and symptoms at presentation were diverse, although epigastric pain was the chief complaint in 27 patients.

9/31. Squamous papilloma of the esophagus diagnosed by cytology. Report of a case with concurrent occult epidermoid carcinoma.

    Esophageal material for cytologic smears was obtained by the gel-foam technique from an 84-year-old man with dysphagia and symptoms of obstruction in whom initial attempts at endoscopic biopsy were nondiagnostic. The smears contained cells with koilocytotic atypia, similar to those described in smears from uterine cervix lesions produced by human papilloma virus. The cytologic diagnosis of an esophageal papilloma of viral origin was confirmed by the second biopsy. A third biopsy, from a lower level of the esophagus following dilatation procedures, revealed an epidermoid carcinoma in situ contiguous with the papilloma.

10/31. Multiple squamous papillomas of the esophagus associated with Goltz syndrome.

    A 30-yr-old white female with a history of focal dermal hypoplasia (Goltz syndrome), chronic gastroesophageal reflux, and dysphagia was found to have, by barium esophagram and esophagogastroduodenoscopy, multiple 2- to 3-mm papillary projections in the distal esophagus and an esophageal stricture. biopsy of these lesions revealed squamous papillomas and a benign stricture. Although chronic irritation from gastroesophageal reflux has been suggested as a possible etiology of acquired esophageal papillomas, the previous association of congenital papillomas of the oral mucosa in Goltz syndrome suggests that the multiple papillomas in this patient are congenital in origin.
