OBJECTIVE To elucidate the cut off levels of serum KL-6 indicating patients with interstitial pneumonitis (IP) and patients with active IP associated with connective tissue diseases (CTDs). METHODS CTD patients whose serum KL-6 level was measured were included. IP was diagnosed on the basis of medical records including XP/CT findings, and active IP was(More)
Seventy-two cases of idiopathic pulmonary fibrosis (IPF) were examined from 2856 consecutive autopsy cases at the Japanese Red Cross Medical Center in Tokyo from 1973-1996. Primary lung cancer had arisen in 31 of 72 cases of IPF (43%), significantly higher than the incidence in cases without IPF (8.1%) and in the cases with non-IPF chronic lung diseases(More)
A 70-year-old woman with a 6-year history of seropositive rheumatoid arthritis (RA) and asymptomatic interstitial lung disease (ILD) began taking etanercept for ongoing arthritis despite treatment with methotrexate (MTX) and bucillamine.

To evaluate the occurrence of granulomatous angiitis and microangiopathy in the lung with sarcoidosis, transbronchial lung biopsy specimens were examined from 174 cases with sarcoidosis. Granulomatous angiitis was seen in 72 cases, which corresponded to 53% of the cases with granulomata. Granulomatous angiitis showed venous involvement (65%), both venous(More)
Sarcoidosis is a systemic granulomatous disease with systemic vascular involvement, that is, granulomatous angiitis and microangiopathy. To determine if there is vascular involvement in cutaneous sarcoidosis, we examined 42 skin specimens taken from 32 patients with cutaneous lesions of sarcoidosis. Cutaneous sarcoidosis was prevalent in older females with(More)
A 45-year-old female developed mild dysesthesia and swelling, followed by ptosisand trigeminal pain, in the right side of the face. Her past medical history was unremarkable, and she had not been aware of any infectious sign. A local otolaryngologist administered glucocorticoid therapy that resolved the face pain, but the ptosis persisted. Neurological(More)
A case of "sclerosing hemangioma" (pneumocytoma) of the lung with lymph node metastasis is reported. A 22-year-old Japanese man was found to have a well-defined round lesion in the right lung (S7), which increased in size slightly during a 2-year follow-up period. He underwent right lower lobectomy with a preoperative diagnosis of a benign lung tumor. The(More)
A 27-year-old man who had a history of bronchial asthma, eosinophilic enteritis, and eosinophilic pneumonia presented with fever, skin eruptions, cervical lymphadenopathy, hepatosplenomegaly, atypical lymphocytosis, and eosinophilia two weeks after receiving trimethoprim (TMP)-sulfamethoxazole (SMX) treatment. After the withdrawal of TMP-SMX and the(More)
We present a case of sarcoidosis acutely aggravated with high fever and diffuse interstitial pulmonary infiltrates in a female patient at the age of 64. Sarcoidosis was diagnosed in another hospital as a result of iritis, chest radiography findings, and a negative reaction in a tuberculin skin test. She was admitted to our hospital because of dyspnea and a(More)
