Carcinoma arising in the pleural cavity following pneumonectomy for hydatid disease.

We report a case of carcinoma following 42 years of chronic empyema in a patient who underwent surgery for a hydatid cyst at the age of 3. At the time of diagnosis, an esophageal fistula was observed and treated with cyanoacrylate. We hypothesize that chronic inflammation of the pleura, caused by decades of empyema, associated with the presence of heterotopic squamous epithelium due to a long-standing esophago-pleural fistula, led to neoplastic transformation.

[Inappropriate antidiuretic hormone secretion syndrome associated with a pleuropulmonary infection]. / Síndrome de secreción de hormona antidiurética asociado a infección pleuropulmonar.

A case of pleuropulmonary infection without a demonstrable causal agent associated to inappropriate secretion of antidiuretic hormone is reported. Although antidiuretic hormone levels were not measured, unequivocal indirect proof of elevated levels was present as evidenced by characteristic serum and urinary electrolyte abnormalities, other possible causes having been carefully ruled out. The hyposmolar clinical picture was refractory to conservative measures, and it was corrected only when a loculated empyema was surgically drained by way of thoracotomy. The literature on inappropriate secretion of antidiuretic hormone related to pleuropulmonary pathology is briefly reviewed. Particular emphasis is made on the pleural encapsulation in the present case as the factor responsible for perpetuation of pulmonary infection and origin of the hormonal disturbance.
