A Case of Spontaneous Remission Organizing Pneumonia after Resection of Thymoma / 대한내과학회지

Thymoma is a rare neoplasm associated with a number of autoimmune disorders and tumors. Organizing pneumonia is a reaction of the lung to various injuries. A feature of organizing pneumonia is plugs of granulation tissue within the lumens of small airways, or alveoli. Causes of organizing pneumonia include various disorders and conditions; however, thymoma with organizing pneumonia located in both lungs is very rare. We report a case of resolving organizing pneumonia after thymoma resection. Our case is the first to demonstrate that resolving organizing pneumonia can occur after thymoma resection, as has been speculated by many researchers.

Desmoplastic Fibroma of the Skull

Desmoplastic fibromas are rare intraosseous bone tumors. They are benign but locally aggressive and frequently found in the long bones and mandible. We report radiographic and histopathologic finding of a case desmoplastic fibroma involving right temporal skull bone. A 53-year-old woman presented at our hospital complaining of continuous right side headaches for a year. Simple skull X-ray film showed 3 x 2.5 cm lytic lesion with mild sclerotic margin on right temporal area. A large craniectomy 1cm lateral to margin was fashioned. The resected mass showed encapsulated mass colored white gray. Histologic diagnosis was compatible with that of a the desmoplastic fibroma. There was no evidence of recurrence during the 15months of follow-up period.
