We report the case of a 53-year-old man who presented with obstructive pneumonitis and broncholithiasis. We attempted to remove the broncholith with forceps through a flexible endoscope, but the potential for bleeding due to partial synechia did not allow this. We succeeded in removing it with cryotherapy. The histopathological diagnosis was thoracic actinomycosis associated with broncholithiasis. Endobronchial actinomycosis with a broncholith is very rare. We successfully treated a patient with endobronchial actinomycosis with a broncholith by administering short-term antibiotics after broncholithectomy via cryotherapy through a flexible bronchoscope.

A few cases of severe pulmonary hypertension with right heart failure associated with Graves’ disease were reported in the literature. However, cases of pulmonary hypertension with right heart failure recurred by Graves’ disease is very rare. We describe the case of a 60-year old woman who had been treated pulmonary hypertension caused by right pulmonary artery thromboembolism seven years ago. Recently, her pulmonary hypertension with right heart failure was recurred by Graves’ disease. The patient’s symptoms of pulmonary hypertension was resolved after treatment of Graves’ disease.

Thyrotoxic periodic paralysis is an acute muscle weakness of the limbs associated with hypokalemia. It can occur with any form of thyrotoxicosis. Thyrotoxic periodic paralysis associated with transient thyrotoxicosis due to thyroiditis is very rare. We experienced a case of thyrotoxic periodic paralysis associated with transient thyrotoxicosis. A 39-yr-old man was referred to our hospital because of paralysis of upper and lower extremity. The laboratory results were hypokalemia and mild thyrotoxicosis. A thyroid scan with Tc-99m revealed decreased uptake in the thyroid area compatible with destructive thyroiditis. The paralytic attack did not recur after the patient recovered to euthyroid state.
