Canine cardiac mesothelioma with granular cell morphology.

Cardiac mesothelioma with granular cell features was diagnosed in a 10-year-old Golden Retriever presenting with pericardial and abdominal effusions. The diagnosis was based on gross, morphologic, and immunohistochemical features. The immunohistochemical profile of the neoplasm was pancytokeratin positive, vimentin positive, and S-100 negative; most gross and morphologic features were consistent with both mesothelioma and granular cell tumor. To the authors' knowledge, the prognosis for either primary cardiac mesothelioma or granular cell tumor in the dog is unknown. At 4 months after thoracotomy, pericardectomy, and mass excision, this dog was alive and without clinical evidence of pericardial or abdominal effusions. We describe a granular morphologic variant of cardiac mesothelioma in a dog.

Unilateral limb enlargement in a dog with a malignant peripheral nerve sheath tumor.

A 3- to 4-month-old female Golden Retriever dog presented with right hind limb enlargement. Physical examination of the limb and radiographic findings initially included soft tissue swelling with elongation, bowing, and cortical irregularity of the femur and tibia. During a period of approximately 7 months, pathology in the limb progressed to include tarsal laxity, muscle atrophy, avulsion of the gastrocnemius muscle, and luxation of the patella. During surgical intervention to shorten the limb and repair the patellar luxation, a large soft tissue cyst was identified along the caudal aspect of the femur and stifle. The limb was later amputated, and a final diagnosis of malignant peripheral nerve sheath (PNS) tumor of the sciatic nerve and surrounding soft tissues was made. The unilateral limb enlargement in this dog appears to have been because of the development and progression of a malignant PNS tumor. The presentation and associated pathologic changes in the limb are unusual for canine PNS tumor but have similarities with neurofibromatosis in the limbs of humans.

Prediction of early-onset asthma in genetically at-risk children.

The W.T. Grant Foundation Asthma Risk Study was designed to prospectively examine children who were considered at a genetically increased risk for the development of asthma. The respective contributions of 11 potential risk factors, both environmental and biological, were assessed in order to determine their relative roles in affecting the early onset of asthma. This is a report of an inception cohort of children born to asthmatic mothers and followed for a 3-year period. All 150 families were recruited from the general community and living within 2 h of the National Jewish Center for Immunology and Respiratory Medicine (Denver, CO). Mothers in the index risk sample had been previously diagnosed with asthma and were recruited during their pregnancy through physician referrals and media solicitation. The index sample of 150 families was 92% Caucasian and predominantly middle class. The mean age of mothers was 29.3 years, and of fathers, 31.1 years. The main outcome was the determination of the early onset of asthma and its association with quantified risk factors. By age 3 years, 14 of the 150 children had developed asthma. Frequent illness, IgE levels at age 6 months, parenting difficulties, and early eczema were significantly associated with the onset of asthma (P = 0.003, P = 0.006, P = 0.01, and P = 0.03, respectively). Only frequent illness, elevated serum IgE levels, and parenting difficulties entered a predictive model where they were independently related to the development of asthma.

Wegener's granulomatosis presenting with erosive arthritis.

We describe a patient with Wegener's granulomatosis who presented with erosive arthritis. The patient's multisystem disease responded to cyclophosphamide treatment, and the erosions healed. Our findings suggest that Wegener's granulomatosis should be added to the differential diagnosis of diseases associated with erosive arthritis.
