The inflammatory pseudotumor of the urinary bladder is rare, especially in children. It is a benign proliferative lesion of the submucosal stroma easily mistaken for a sarcoma clinically, so it should be differentiated from a malignant neoplasm. We report the case of bladder inflammatory pseudotumor in a 7-year-old girl.

[Show abstract][Hide abstract] ABSTRACT: Inflammatory pseudotumor (IPT) of the liver is rare benign tumor. When the diagnosis of IPT is established with biopsy, simple observation or conservative therapy is preferred because of the possibility of regression. But IPT is unresponsive to the conservative treatment, surgical resection should be considered. We experienced a 63-year-old male, who was suspected hepatocellular carcinoma in abdominal computed tomography (CT) and magnetic resonance image (MRI) scan, presented with 2-month history of intermittent fever and weight loss. Percutaneous ultrasound guided core biopsy confirmed IPT of the liver. Non-steroidal anti-inflammatory drugs and antibiotics were administered for 8 and 4 weeks, respectively, but fever continued. So, extended right hepatectomy was performed for IPT of the liver and then fever subsided. The patient remains well during a follow-up period of 12 months.

[Show abstract][Hide abstract] ABSTRACT: A young woman who presented with a recurrent bladder tumor was detected on follow up to be harboring a prolapsed bladder tumor at the external urinary meatus mimicking an anterior vaginal polyp. Excision and histopathological examination revealed an organized hematoma (pseudotumor). The literature regarding this clinical curiosity and its differential diagnosis is reviewed and discussed.

[Show abstract][Hide abstract] ABSTRACT: Many significant benign and malignant nonepithelial tumors and stromal tumor-like lesions arise in the prostate gland. Although such lesions are rare, their recognition by the pathologist is essential because their treatment and prognosis are quite variable. In this review, lesions of the specialized prostatic stroma, that is, lesions that can be seen in the stroma of the prostate but not in that of other organs, except for the phyllodes type of lesions, are discussed. Benign and malignant lesions of the soft tissues that occur in the stroma of other organs and are seen with some frequency in the prostate are also discussed. Few of the rarer soft tissue lesions are mentioned. Lesions and tumors with melanocytic differentiation, hematopoietic derivation, and germ cell tumors are described. It is hoped that this review will serve as a useful reference when encountering some of these lesions, all of which are referenced to their original and subsequent reports. Some non-English language references are also cited to reflect the international recognition of these lesions or to give credit to the author who first described the entity.
