Dysphagia and stenosis secondary to intramural esophageal pseudodiverticulosis.

We present the case of a patient with smoking, alcoholism, cirrhosis and HIV who was endoscopically diagnosed with esophageal candidiasis due to an episode of dysphagia. After treatment with antifungals and PPIs, the patient remained asymptomatic for almost 3 years. He presented an event of food impaction that was resolved by an upper endoscopy in which an esophageal stenosis and multiple esophageal pseudodiverticulosis were visualized. The biopsies only showed chronic nonspecific esophagitis. The stenosis was dilated with a balloon and PPIs were continued, with good response. Esophageal intramural pseudodiverticulosis is rare and can lead to motor disorders and strictures. It has a doubtful association with HIV and a clearer relationship with alcoholism, smoking, diabetes, reflux and candidiasis. The endoscopic diagnosis can be difficult so in order to make an accurate diagnosis is necessary an esophagram or CT. Treatment is based on controlling risk factors and dilating stenosis. The prognosis is usually favorable.

Colocación de prótesis esofágica para el fracaso del tratamiento endoscópico / Esophageal stent placement for endoscopic treatment failure

Up until approximately 10 years ago, the treatment for acute refractory esophageal variceal bleeding was balloon tamponading. Esophageal fully covered self-expanding stents are considered as effective as balloons and also much safer. They are kept in situ for longer periods, what eases the access to more definitive treatments with a low complication rate. We present 6 cases of patients with cirrhosis and massive bleeding due to esophageal varices refractory to conventional treatment, successfully treated with an esophageal fully covered self-expanding stent. There were no major complications, achieving an effective bleeding control in all cases.(AU)

A rare endoscopic finding: primary esophageal melanoma.

We report a case of a patient accidentally diagnosed with an esophageal lesion compatible (histologically and immunohistochemically) with epithelioid melanoma. The skin examination did not reveal any evidence of melanoma and the patient was diagnosed with primary malignant melanoma of the esophagus. It's a very rare tumour. The majority of melanocytic lesions of the gastrointestinal tract are presumably secondary to a cutaneous melanoma and in order to discard this, a thorough skin examination is needed. Diagnosis is based on endoscopic image, histological data and especially on immunohistochemical evaluation. Primary malignant melanoma has a very poor prognosis as it usually presents distant metastasis when diagnosed. Surgery (with or without associated immunotherapy) remains the base of treatment in absence of advanced disease.
