Pulmonary Langerhans Cell Histiocytosis Accompanied by Active Pulmonary Tuberculosis / 대한흉부외과학회지

ABSTRACT

Pulmonary Langerhans cell histiocytosis is very rare, especially when accompanied by active pulmonary tuberculosis. A patient was hospitalized due to excessive dyspnea and she was diagnosed with active pulmonary tuberculosis by a sputum AFB smear. The HRCT taken after hospitalization showed multiple micronodules and tiny cysts. An open lung biopsy confirmed the coexistence of pulmonary Langerhans cell histiocytosis.
