A Rare Case of Chest Wall Castleman's Disease with Calcification.

Castleman's disease with calcification of the chest wall is very rare, and there have been few reports of such cases to date. A 57-year-old woman was referred to our hospital for a tumor with calcification on her left lateral chest wall, which was detected on chest computed tomography. Findings of her chest magnetic resonance imaging suggested schwannoma or a solitary fibrous tumor, and therefore, we performed surgery for diagnostic and therapeutic purposes. Pathologically, the tumor with calcification was diagnosed as Castleman's disease of the hyaline-vascular type. After the surgery, the patient has had no obvious symptoms and continues to undergo regular follow-up examinations.
