[Diagnosis and treatment of pulmonary histoplasmoma: report of 3 cases].

OBJECTIVE

To investigate the diagnosis and treatment of pulmonary histoplasmoma.

METHODS

The clinical data of 3 patients with pulmonary histoplasmoma. 2 males, both 49-years-old, and 1 female, 27-years-old, were analyzed.

RESULTS

Nodules in the lung, regardless solitary or multiple, with clear border and calcification, were the first radiological finding. All 3 patients were misdiagnosed as with tuberculosis or primary or metastatic lung neoplasm and underwent operation. The diagnosis was confirmed after surgery. Pathological examination showed caseous necrosis and a great amount of histoplasma in the multinuclear cells. Follow-up lasting 1, 2, and 3 years respectively showed no recurrence.

CONCLUSION

Pulmonary nodule, regardless solitary or multiple, with clear border and calcification, is the first radiological finding of pulmonary histoplasmoma Autopsy is necessary for diagnosis of pulmonary histoplasmoma, difficult to diagnose, however, with a good prognosis.
