Usually identified during histologic examination for other diseases, they have to date been identified virtually only in adults, where they are more common in females and overweight\/obese individuals.

Five underwent biopsy and 1 underwent autopsy. One was obese, 2 underweight, and 3 within normal weight range. Underlying diseases included immune-mediated interstitial disease, chronic airway disease, metastatic osteosarcoma, and fatal cerebrovascular accident. Thoracic CT showed diverse findings including small nodules in 3 patients. Lesional cells showed round-to-ovoid nuclei and moderate amounts of pink cytoplasm; they were disposed in vaguely whorled clusters surrounding\/abutting small blood vessels. Size ranged from 165 to 343\u2009\u00b5m.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Our findings confirm MPMN are not exclusive to adults; within pediatrics, susceptibility occurs in the second decade.
