Calcifying fibrous pseudotumor of the adrenal gland: A rare case report.

Calcifying fibrous pseudotumor (CFP) is a rare benign soft tissue lesion. We herein present an extremely rare case of CFP of the adrenal gland. A 32-year-old male patient presented to our hospital with a tumor-like lesion in the area of the left adrenal gland detected by ultrasound during a routine check-up several days prior. Contrast-enhanced magnetic resonance imaging examination revealed a solitary, well-circumscribed mass, in close proximity to the medial arterial branch of the left adrenal gland. Histological examination revealed that the tumor consisted of sheets of varying amount of inflammatory cell infiltration; interstitial fibrosis and psammomatous calcifications were also observed. To the best of our knowledge, this is the third case of CFP occurring in the adrenal gland in the published literature. We herein report the findings of this case and review the two previously reported cases of CFP of the adrenal gland with valuable information.
