Pentastomiasis in Canada.

We report a case of human pentastomiasis in a 28-year-old man who emigrated to Canada from Nigeria in 1982 and died as a result of a motor vehicle accident in 1989. At autopsy, in addition to trauma, numerous small cystic nodules (3 to 9 mm in diameter) were discovered in the liver, pleura, lungs, and mesentery and under the intestinal and parietal peritoneum. The parasites were diagnosed as well-preserved, encysted Armillifer armillatus nymphs. Neither degenerative nor inflammatory granulomatous reactions were observed in the adjacent tissue. To our knowledge, this is the first reported case of human infection with encysted nymphs of A armillatus and the eighth reported case of pentastomiasis in North America.

Calcification in bronchopulmonary sequestration.

We report an unusual complication in a patient with intralobar bronchopulmonary sequestration. Chest tomography, computed tomography, and specimen radiography showed a mass containing numerous round calcifications in the posterior basal segment of the left lower lobe. Pathologic examination disclosed an Exophiala fungus infection and broncholiths within bronchiectatic cavities in the sequestered segment.

Skeletal lymphoma.

The records of forty-two patients with lymphoma of bone [.11 with Hodgkin disease (HD), 31 with non-Hodgkin lymphoma (NHL)] were retrospectively reviewed to correlate histologic type with sites of osseous involvement, radiographic patterns of bone destruction, and prognosis. The vertebral column was the most frequent site of axial involvement and the femur was the commonest site overall. In HD, the most frequent radiographic pattern was vertebral sclerosis, while periosteal reaction was noted in two focal femoral lesions and hypertrophic pulmonary osteoarthropathy in one patient. In NHL, permeative destruction predominated, while unusual layered periosteal reaction and eccentric cortical destruction were each seen in two patients. Radiographic patterns of bone involvement alone cannot be used to predict histologic type or prognosis. Staging remains the most important prognostic indicator. For skeletal lymphoma, instead of the traditional Ann Arbor Staging System, we prefer the more specific Mayo Staging System which relates the temporal appearance of osseous disease to nodal or soft-tissue disease or both.
