OBJECTIVE To determine a paradigm that will be helpful for urologists to manage fibrous pseudotumors, which are a very rare condition of the testis. MATERIAL AND METHODS We retrospectively evaluated the patients with fibrous pseudotumors in our uropathological database from 1995 to 2013. Patients who had tumor markers and ultrosonography (USG) screening before surgery and a final pathology re...

Inflammatory myofibroblastic tumor (IMT), also called "inflammatory pseudotumor", is a rare benign tumor composed of spindle cells with a variable infiltrate of inflammatory cells and fibrous tissue. There have been many reported cases of IMT in every organ system; however, IMT in the mediastinum is rare. We report a rare, proven case of spontaneous regression of IMT in the right cardiophrenic ...

INTRODUCTION Inflammatory pseudotumor is rare benign mass composed of chronic inflammatory cell infiltration and proliferating fibrous tissue. Some cases of inflammatory pseudotumor show abundant infiltrating IgG4-positive plasma cells and obliterative phlebitis, which are the pathologic hallmarks of autoimmune pancreatitis. CASE PRESENTATION A 77-year-old Japanese man was admitted to our hos...

Nodular fasciitis falls within the benign spectrum of fibrous soft-tissue tumors. We present a case of nodular fasciitis in the supraclavicular fossa in which an unusual angiographic presence of neovascularity is shown.

An inflammatory pseudotumor is a rare benign lesion consisting of fibrous tissue and inflammatory cells. Although it can appear anywhere in the body, the most common site for this lesion is the lung.1 The hepatic counterpart was first described in 1953 by Pack and Baker.2 Since then only about 50 cases have been reported in the literature.3 The clinical and pathologic features have been well de...

Calcifying fibrous pseudotumors are rare soft-tissue lesions pathologically characterized by hyalinized collagen, psammomatous or dystrophic calcification, and lympho-plasmacyte infiltration. They are clinically benign with an extremely low rate of recurrence and complete surgical resection is known to be the treatment of choice. We performed the resection of a calcifying fibrous pseudotumors i...

A female patient developed persistent facial pain beginning at age 19 years. Intermittent motor and sensory disturbances referable to one hemisphere began nine years later and by the age of 41 she had developed signs of increased intracranial pressure. Exploratory craniotomy revealed replacement of the leptomeninges by thick, fibrous tissue. The histological appearance was that of a chronic, be...
