Pneumocystis carinii pneumonia in gastric cancer patients without acquired immune deficiency syndrome: 3 cases report and literature review
نویسندگان
چکیده
Pneumocystis carinii pneumonia (PCP) has rarely been reported in solid tumor patients. It is a well-known complication in immunosuppressed states including acquired immune deficiency syndrome and hematologic malignancy. PCP has been reported in solid tumor patients who received long-term steroid treatment due to brain or spinal cord metastases. We found 3 gastric cancer patients with PCP, who received only dexamethasone as an antiemetic during chemotherapy. The duration and cumulative dose of dexamethasone used in each patient was 384 mg/48 days, 588 mg/69 days, and 360 mg/42 days, respectively. These cases highlight that the PCP in gastric cancer patients can successfully be managed through clinical suspicion and prompt treatment. The cumulative dose and duration of dexamethasone used in these cases can be basic data for risk of PCP development in gastric cancer patients during chemotherapy.

Lung cavitation associated with Pneumocystis carinii infection in the acquired immunodeficiency syndrome: a report of six cases and review of the literature.
Lung cavitation in patients with the acquired immune deficiency syndrome (AIDS) and Pneumocystis carinii pneumonia (PCP) has mainly been reported as single case studies. Among 160 episodes of PCP seen in a 1,000 bed teaching hospital and a 600 bed teaching hospital from 1985-1992, we found six cases presenting with lung cavitation and documented Pneumocystis carinii infection. In the cases we r...

We report a case of endobronchial Pneumocystis carinii infection in a patient who most likely had the acquired immune deficiency syndrome (AIDS). Although many unusual manifestations of Pneumocystis pneumonia have been reported in patients with AIDS, this is the first case of P carinii presenting as an endobronchial mass.

Patients with acquired immune deficiency syndrome (AIDS) are at increased risk for pneumothorax, which usually occurs in the setting of Pneumocystis carinii pneumonia. The rationale of the present study was based on the hypothesis that the increased incidence of pulmonary tuberculosis in human immunodeficiency virus (HIV)-infected patients could favour the development of pneumothorax in such pa...

Pneumocystis carinii pneumonia is a frequent manifestation of the acquired immune deficiency syndrome (AIDS). It usually presents radiologically as diffuse bilateral infiltrates and histologically as a foamy, eosinophilic intra-alveolar exudate containing the organisms' cysts. We recently studied two rare cases of P carinii pneumonia presenting as pulmonary nodules on chest x-ray films in two p...
