title: Spontaneous resolution of a plasma cell granuloma in a 9-year-old.
abstract: A previously healthy 9-year-old white boy presented with a 13-lb weight loss over a period of 4 weeks and a 4.5-cm mass in the right lung. Histology was compatible with a plasma cell granuloma, which is the most common benign childhood lung tumor. Surgical management with segmental or wedge resection is the usual standard of care in this situation. However, it has been suggested that with a confirmed histologic diagnosis surgical resection is not warranted. This patient was managed conservatively. Repeat computed tomography scan 6 weeks later revealed significant resolution of the lesion, and at 7 months the lesion had totally resolved. Spontaneous resolution of this lesion has been rarely described in pediatric populations.
