[Case of broncholithiasis lithoptysis occurring spontaneously after repeated pneumonia].

An abnormal chest shadow was pointed out in a 56-year-old woman in a health check in 2001. She had pulmonary tuberculosis at age 11. Because of repeated fever for the previous 2 years, she visited our hospital in 2003 and right upper lobe pneumonia was detected with a calcified nodule that completely obstructed the right upper lobe bronchus on CT. After admission, she spontaneously expectorated a stone. The composition of the stone was 57% calcium phosphate and 43% calcium carbonate. Radiological findings and the composition of the stone suggested that this broncholith was calcified bronchial mucus rather than a calcified lymph node that might have perforated into the airway. Bronchiectasis of the right B3 broncus was observed on CT scan after lithoptysis. Although the bronchiectasis was unchanged 2 years later, she had no symptoms, such as fever or cough.

[A case of atypical pulmonary carcinoid accompanying skin metastasis].

A 73-year-old woman underwent cranial surgery in 1999 after receiving a diagnosis of suspected malignant meningioma. She began complaining of headache 2 years postoperatively, and around the same time, she noticed a painful skin tumor. She was then transferred to our hospital for further evaluation. The skin tumor was diagnosed by skin biopsy as an atypical metastatic carcinoid tumor. Systemic examination demonstrated a primary lesion in the left lung. Pulmonary, skin and bone biopsy samples exhibited the same pathological findings as those of the atypical pulmonary carcinoid tumor. She did not show any carcinoid symptoms. EP therapy (etoposide + carboplatin) and CAV therapy (cyclophosphamide + doxorubicin + vincristin) were administered, but there was no clinical response. The patient is currently doing well without chemotherapy and is being followed by the Outpatient Department.
