Linfoma no Hodgkin primario de esófago: Reporte de un caso

El Linfoma esofágico primario es un tumor muy raro, representa menos del 1% de los tumores esofágicos. Se reporta el caso un paciente con linfoma no Hodgkin localizado en esófago medio e inferior, que consulta por disfagia, siendo diagnosticado y tratado exitosamente con quimioterapia, con sobrevida de 12 meses, hasta la actualidad asintomático y sin evidencia de tumor.

SUMMARY Primary esophageal lymphoma is a very rare tumor; represents less than 1 % of all esophageal tumors. We report a case of a patient with no-Hodgkin lymphoma involving the medial and lower esophagus, presenting with dysphagia, he was treated successfully with chemotherapy, with an over all survival of 12 months. He is at the moment, asymptomatic and without evidence of tumor.

Primary Non-Hodgkin T-Cell Lymphoma of the Esophagus / 대한혈액학회지

Esophageal involvement of non-Hodgkin lymphoma is extremely unusual; primary lymphoma is even less common. When lymphoma is found in the esophagus, generally it is the case with contiguous involvement of the gastric fundus, the cervical node, secondary to mediastinal lymph node compression, or late manifestation of advanced disease. Such cases cannot be labeled as primary esophageal lymphoma. We describe a case of primary esophageal non-Hodgkin T-cell lymphoma diagnosed by endoscopy and CT scan with the review of literatures.

Spontaneous Regression of Primary Malignant Lymphoma of the Esophagus / 대한소화기내시경학회지

Gastrointestinal involvement has been reported to occur in about 5 to l0% of patients with lymphoma. The most common gastrointestinal site for a lymphoma is the stomach, followed by the small intestine and ileocecal region. When lymphoma is found in the esap us, generally it is with contiguous involvement of the gastric fundus, the cervical node, secondary to mediastinal lymph node compression, or a late manifestation of advanced desease. Such cases cannot be labeled as primary esophageal lymphoma. A search of the literature reveals that there have been about 20 or more published cases classified as esophageal lymphoma. However, more than ten cases are indistingishable from the case of distal esophageal involvement by gastric lymphoma. In 1935, Chiolero described a case of midesophageal stricture, which at autopsy was consistent with Hodgkin's disease for the first time. Berman reported an authentic case of primary histiocytic lymphoma confined to the lower esophagus. Only six or more cases were reported in literature until the present time. Here, a 30-year-old man with substernal discomfort was shown to have a mass lesion on the esophagus. The mass was proved to be malignant lymphoma on the histologic examination. This may be the first report dealing with spontaneous regression of maligant lymphoma of the esophagus possibly associated with the use of cimetidine.
