Persistence of immunological alterations after thymectomy in Good's syndrome: a clue to its pathogenesis.

Analyzing the phenotypic characterization of the immune system cells involved in the pathogenesis of immunodeficiency with thymoma (Good's syndrome) is difficult due to the low number of studies on that subject. We describe the immunological alterations observed in a case of Good's syndrome, and we summarize the pathogenic explanations found in the literature.

[Acute pancreatitis and obstructive jaundice secondary to metastases from lung cancer]. / Pancreatitis aguda e ictericia obstructiva secundaria a metástasis de cáncer de pulmón.

Lung cancer is one of the most frequent neoplasms. The symptoms are due to the cancer itself, its extension, and associated paraneoplastic syndromes. Although biliopancreatic metastases are common, biliopancreatic involvement as the initial symptom of lung cancer--whether as pancreatitis or obstructive jaundice--is rare. We describe our clinical experience, reporting two patients with acute pancreatitis and one patient with obstructive jaundice as the clinical presentation of advanced lung cancer. We also provide a brief review that highlights the absence of guidelines in this situation.
