Respiratory tract infections with mycoplasma can cause severe infiltrating pneumonia (with pleuritis), associated with marked inflammatory reactions (maximal E.S.R., high leucocytosis with shift to the left and marked alpha 2-proteinaemia). Serial measurements of cold-agglutinin titres as well as complement-fixation reaction to Mycoplasma pneumoniae will confirm the diagnosis. Atypical forms of pneumonia can also be documented in that they respond only to erythromycin and extrapulmonary complications accompany the disease, giving them a protean character. In two such patients there was the clinical picture of pneumonia with high fever and marked inflammatory reaction, associated with anicteric hepatitis. In one there was also thoracic lymphadenitis, myositis and rash, in the other a meta- and post-infectious polyarthritis.

Systemic pathological alterations were studied in thirty-seven autopsied patients with Kawasaki disease. Systemic vasculitis was the most characteristic pathological finding and was present in all the patients. In addition to the vasculitis, there was a high incidence of inflammatory lesions in various organs and tissues: in the heart, endocarditis, myocarditis, and pericarditis; in the digestive system, stomatitis, sialoduct-adenitis, catarrhal enteritis, hepatitis, cholangitis, pancreatitis, and pancreas ductitis; in the respiratory system, bronchitis and segmental interstitial pneumonia; in the urinary system, focal interstitial nephritis, cystitis, and prostatitis; in the nervous system, aseptic leptomeningitis, choriomeningitis, gangliontis, and neuritis; in the hematopoietic system, lymphadenitis, splenitis, and thymitis. Dermatitis, panniculitis or myositis were also observed in some patients. Therefore, Kawasaki disease is a systemic inflammatory disease which mainly affects the cardiovascular system. These systemic inflammatory lesions are considered to correspond to the variegated clinical manifestaitions. The relationship between Kawasaki disease and infantile polyarteritis nodosa (IPN) were discussed, based on the clinicopathological characteristics.

A naturally occurring case of Tyzzer's disease due to infection with Bacillus piliformis in a wolf-dog hybrid resulted in widely disseminated lesions, including severe myocarditis, hepatitis, enterocolitis, intestinal leiomyositis, and adrenal cortical adenitis. Previously reported lesions for canine Tyzzer's disease have been limited to hepatic necrosis and a necrotizing enterocolitis.

A 3-year-old female Basset Hound was examined because of fever and lameness of 2 months' duration. Physical examination revealed a small cranial abdominal mass, which had an ultrasonographic appearance of a large abdominal lymph node. Cytologic examination of an ultrasound-guided fine-needle aspirate of the mass revealed a few macrophages that contained numerous linear unstained structures consistent with mycobacteria. Intracellular acid-fast bacilli were identified in an aspirate that was stained with modified Ziehl-Neelsen. Exploratory laparotomy revealed wide-spread abdominal lymphadenopathy. Histologic examination of hepatic and lymph node biopsy specimens revealed chronic granulomatous hepatitis and lymphadenitis. Acid-fast organisms isolated after bacteriologic culturing of a mesenteric lymph node specimen were identified as Mycobacterium smegmatis. Because the prognosis was poor, the dog was euthanatized.

We describe the first case of an Epstein-Barr virus (EBV)-associated natural killer-large granular lymphocyte (NK-LGL) leukemia in the United States to the best of our knowledge. A 29-year-old woman of Japanese descent developed EBV infection after a blood transfusion as indicated by a rise in serum antibody titers. Peripheral blood and bone marrow aspirate smears demonstrated increased LGLs. Flow cytometry showed that these cells expressed NK-associated surface antigens. Cytogenetic analysis of the bone marrow aspirate showed two distinct but related clones with multiple copies of a modified 7 marker chromosome. Death followed colonic perforation. Findings at necropsy included bone marrow lymphocytosis and erythrophagocytosis, a mononucleosis-like lymphadenitis, atypical hepatitis with a mixed, predominantly T-cell infiltrate, interstitial pneumonitis, and multiorgan system vasculitis with perforation of the transverse colon. Epstein-Barr virus transcripts were identified in lymphocytes infiltrating liver and peripheral nerve by in situ hybridization. In addition, Southern blot analyses showed monoclonal bands superimposed on oligoclonal ladders of EBV termini in liver and lymph node. The identical episomal form of EBV was found in the bone marrow, lymph node, and liver. No immunoglobulin (Ig), T-cell receptor beta, or T-cell receptor gamma chain gene rearrangements were identified. These studies support the hypothesis that the LGL population was a neoplastic EBV-related clonal proliferation of NK cells.

Disseminated infection with Mycobacterium avium complex is described in 3 adult Siamese cats. All cats were the result of father-daughter matings. Clinical signs included anorexia, weight loss, and lethargy. Physical examination revealed pale mucous membranes, lymphadenopathy, splenomegaly, and pyrexia. Nonregenerative anemia was detected in all 3 cats, and macrocytosis was observed in 2. An antemortem diagnosis of mycobacterial infection was made on the basis of identification of acid-fast bacilli in tissue aspirates. The cats died or were euthanatized owing to clinical deterioration, despite antibiotic treatment. Necropsy findings included granulomatous lymphadenitis, enterocolitis, pneumonia, cellulitis, myelitis, and hepatitis. Organisms from the Mycobacterium avium complex were identified in bacteriologic cultures of tissue samples.

Five pregnant queens were inoculated orally with Toxoplasma gondii tissue cysts. Twenty-two live and three dead kittens were born 16 to 31 days after inoculation. Four kittens were eaten by queens and, thus, were not available for histologic examination. Twenty-one kittens that died or were euthanatized on day 2 (two kittens), 4 (one kitten), 5 (five kittens), 6 (five kittens), 7 (one kitten), 8 (four kittens), 16 (two kittens), and 29 (one kitten) after birth were studied histologically. T gondii was detected by bioassay and was seen in histologic sections of tissues from all 21 kittens. The histologic lesions associated with neonatal toxoplasmosis were widely disseminated infiltrates of macrophages and neutrophils often accompanied by necrosis; lymphocytes and plasma cells were occasionally present. The most consistent lesions were proliferative interstitial pneumonia (21/21); necrotizing hepatitis (20/21); myocarditis (21/21); skeletal myositis (21/21); glossal myositis (19/19); nonsuppurative encephalitis affecting the cerebrum (18/18), brain stem (15/15), and spinal cord (9/9); uveitis (19/19); necrotizing adrenal adenitis (18/18); and interstitial nephritis (16/21). Placental lesions (2/2) consisted of grossly visible areas of necrosis and mineralization.

Disseminated Mycobacterium scrofulaceum infection has rarely been reported, and the majority of infections have been associated with AIDS or other immunocompromising diseases. We describe a previously healthy man with M. scrofulaceum infection whose clinical manifestations included miliary lung lesions, mediastinal lymphadenitis, granulomatous hepatitis, osteomyelitis, subcutaneous abscesses, and probable renal involvement. M. scrofulaceum was isolated from multiple specimens of sputum, urine, and the abscesses. The patient was treated successfully with the combination of isoniazid, ethambutol, rifampin, and ofloxacin. To our knowledge, this is the first detailed description of an extensively disseminated infection due to M. scrofulaceum in an immunocompetent host since the advent of AIDS.

Primary hepatobiliary tuberculosis is difficult to diagnose and treat. We describe a woman with obstructive jaundice, a common hepatic duct stricture, and granulomatous hepatitis diagnosed with biliary tract tuberculosis when acid-fast bacilli were found in bile aspirated during endoscopic retrograde cholangiopancreatography (ERCP). The hilar stricture resulted from either primary biliary tuberculosis or secondary inflammation related to tuberculous periportal adenitis and persisted despite adequate medical treatment for tuberculosis, apparently the result of postinflammatory stenosis. After 20 months, the patient had persistently elevated bilirubin due to the stricture, and liver biopsy revealed early secondary biliary cirrhosis. Placement of a permanent metal biliary stent produced excellent results. Both diagnosis of hepatobiliary tuberculosis by bile aspirate and treatment of a biliary stricture with a permanent metal biliary stent are newly described advances in the management of biliary tuberculosis made possible by ERCP.

Cat-scratch disease is a subacute, regional lymphadenitis syndrome that occurs mainly in children. The causative agent is Bartonella henselae. After an incubation period ranging usually between 1 and 2 weeks, red papules develop at the site of cutaneous inoculation and persist until the development of lymphadenopathy with some malaise. Cases with complications have been observed including Parinaud oculoglandular syndrome, encephalopathy, a variety of exanthems and granumatous hepatitis. Diagnosis is based on serologic tests and, when necessary, antimicrobial treatment can be considered. Incision and drainage should not be done.
