344 Calcifying fibrous pseudotumor (CFP) is an unusual benign lesion of the soft tissue. CFP is regarded as related to inflammatory pseudotumor and it may sometimes represent a late stage of inflammatory pseudotumor, in that a CFP appears to be arising within an inflammatory pseudotumor. 1 This entity occurs predominantly in young adult patients and has a good prognosis. 2 CFPs are found mostly...

We present a case of fibrous pseudotumor of the epididymis and tunica vaginalis which is one of the rarest paratesticular tumors. Fibrous pseudotumor presents as a solid scrotal mass with normal serum markers. Pathological examination is the only reliable way to make the diagnosis with these tumors exhibiting characteristic macroscopic and microscopic features. It is important to recognize this...

Calcifying fibrous pseudotumor is a rare, benign, hypocellular tumor-like lesion that is characterized by the presence of dense hyalinized collagenous tissue interspersed with small spindle cells, dystrophic calcifications, or psammomatous and variable lymphoplasmacytic infiltrations. We report the case of a 37-year-old woman with a posterior mediastinal mass, in close contact with the distal t...

We describe a 16-year-old male with ultrasound evidence of a 1.3 cm right paratesticular nodule, which was managed by intraoperative frozen section and excisional biopsy. The pathologic findings were consistent with benign fibrous pseudotumor of the tunica vaginalis testis, which is a very rare lesion in the pediatric population. Consideration of fibrous pseudotumor in the differential diagnosi...

Although the majority of mesenchymal lesions of the gastrointestinal tract are neoplastic in nature, but nonneoplastic reactive processes may also involve the gastrointestinal tract and mesentery. Some more aggressive neoplasms located in same area, such as fibromatosis or gastrointestinal stromal tumors may be cause of diagnostic confusion. Reactive nodular fibrous pseudo tumor (RNFP) of the g...

Calcifying fibrous pseudotumor is an uncommon lesion and has recently been recognized as a distinctive fibrous lesion. Esophageal calcifying fibrous pseudotumor is extremely rare and, to the best of our knowledge, has never been reported before. A 54-year-old woman underwent upper gastrointestinal endoscopy and endoscopic ultrasound because of intermittent dysphagia. The results showed 1 isoech...

Tumors arising in the spermatic cord are very rare. The common benign tumors of the spermatic cord include adenomatoid tumor, lipoma, neurofibroma, and leiomyoma. We report a rare case of fibrous pseudotumor of the spermatic cord presenting clinically as a hydrocele. A 28-year-old male presented with the complaint of swelling in the left scrotum, which gradually progressed in size over four yea...

OBJECTIVES The stroma-rich variant of hyaline-vascular type of Castleman's disease (SR-HVCD) should be differentiated from vascular or follicular dendritic reticulum cell neoplasms. In this paper, we present a rare case of HVCD. We also suspect a possible association between SR-HVCD and calcifying fibrous pseudotumor. METHODS A 34-year-old man was found an abdominal mass by computed tomograph...
