[Diffuse large cell lymphoma with spontaneous regression in the lung and lymph nodes. Case report].

An 84-year-old woman was admitted to our hospital because of swelling of the cervical lymph nodes and multiple tumorous lesions observed on radiographic studies. Transcutaneous lung biopsy was performed, but necrosis of the tissue was too marked to make a diagnosis. The diagnosis of diffuse large-cell lymphoma was made based on a biopsy of the pretracheal lymph node. During the first two months after admission, the left cervical lymph nodes and most of the pulmonary lesions regressed not withstanding of special treatment for lymphoma. The patient eventually died of generalized peritonitis. At autopsy, metastasis of systemic organs by malignant lymphoma was observed. Most of the lung regions were cicatrized, but clusters of atypical lymphocytes were observed in the necrotic tissue. The tumor in the mucosa of the small intestine showed necrosis, which accounted for the intestinal perforation. The total clinical course after admission was about six months. Spontaneous regression of diffuse large cell lymphoma is rare, and this is the second reported case in Japan.

[A case of primary antiphospholipid syndrome with fever, pulmonary thromboembolism and endocardial lesion].

A previously healthy 16-year-old girl complaining of fever, hemosputum, chest pain and dyspnea was hospitalized. On admission, physical examination revealed mental confusion, holosystolic heart murmur, and swelling of the left foot. Laboratory investigations showed anemia, leukocytosis, thrombocytopenia, activation of inflammatory reactions, prolongation of PT and APTT, and hypoxia. Antinuclear antibody test was negative. There were no other findings suggestive of collagen diseases such as SLE. Chest X-ray showed consolidation in the left lower lung field and pleural effusion. Echocardiography disclosed a mass lesion in the left atrium in contact with the mitral valve, and mitral regurgitation. No findings indicative of an infectious etiology were present. The patient rapidly improved with high dose corticosteroid and anticoagulant therapy. A venogram of the lower extremity disclosed deep venous thrombosis. A lung ventilation-perfusion scan revealed multiple pulmonary thromboemboli. Elevation of anticardiolipin antibody was noted. Based on these findings, the diagnosis of primary antiphospholipid syndrome was made. Further administration of steroid and anticoagulant resulted in decrease of the titer of anticardiolipin antibody. This is the second report of primary antiphospholipid syndrome in Japan. The clinical significance of this disease is also discussed.

[A case of primary pulmonary sporotrichosis].

We report the first case of primary pulmonary sporotrichosis in Japan. A 53-year-old man was admitted to our hospital for further examination of the abnormal shadows on chest X-ray film. Six months before admission, he was admitted to another hospital because of alcoholic liver disease and diabetes mellitus. Since the initial chest film showed cavities with infiltration in the left upper lung field, he was treated with antituberculous drugs despite negative sputum cultures for mycobacterium. In spite of the medication, his chest X-ray film revealed another cavitary lesion, so he was referred to our hospital. He had been asymptomatic during this period. Chest X-ray on admission disclosed multiple cavities in the left upper lobe and a cavity in the right lower lobe. Repeated sputum specimens, bronchial washings and brushings for cytology and cultures were all negative. In an attempt to clarify the pathogen, percutaneous lung aspiration (PLA) was performed. The PLA sample yielded a positive culture of Sporothrix shenckii. After the diagnosis, S. schenckii was also cultured from sputa. A sporothrix skin test and yeast agglutination test for S. schenckii were positive. In the absence of a history for skin lesion, the patient was diagnosed as a primary pulmonary sporotrichosis. As iodide therapy was ineffective, he was started on a regimen of intravenous amphotericin B. However his renal function progressively deteriorated, so amphotericin B was discontinued. Now he receives miconazole intravenously and is still under careful observation. As far as we know, this is the first report of primary pulmonary sporotrichosis in Japan. The possibility of sporotrichosis should be considered in any cases of undiagnosed cavitary lung diseases.

[Two cases of Hermansky-Pudlak syndrome with interstitial pneumonia].

Two cases of Hermansky-Pudlak syndrome with interstitial pneumonia were reported. Both patients had evidence of pulmonary involvement characterized by diffuse bilateral infiltrates. They had oculocutaneous albinism. Case 1 was a 55 year-old female who had a history of easy bruising. Her two sisters were albino and had died of pulmonary fibrosis. One of them was diagnosed as Hermansky-Pudlak syndrome on autopsy. Bone marrow aspirate disclosed typical macrophages with ceroid-like pigment. Transbronchial lung biopsy showed alveolar wall thickening. Lumi-aggregometer showed a decrease of platelet aggregation and an absence of ATP release. Case 2 was a 43 year-old female and had a bleeding tendency during a surgical procedure. Lumi-aggregometer showed normal platelet aggregation but an absence of ATP release. BALF analysis did not disclose macrophages with ceroid-like pigment.

Deposits of mucosubstances on the cornea by topical chloramphenicol: an electron microscopic study.

Chloramphenicol was instilled into rabbit eyes and five days later the corneal surface was examined by scanning electron microscopy. The corneal surface was roughened and showed a proliferative appearance. Examination of thin sections of the cornea by transmission electron microscope showed that the corneal surface stained strongly with alcian blue. It was thus supposed to be a deposit of mucosubstances. Mucosubstances increase pathogenicity of bacteria and, therefore, this deposit may accelerate Pseudomonas keratitis after chloramphenicol application.
