Orbital inflammatory pseudotumor is a rare complication of systemic lupus erythematosus. It may present a challenge for differential diagnosis, especially in the context of treatment with hydroxychloroquine, although dosage and duration of the treatment may guide us. Although high antibody titers can be found, this is not specific.

IgG4-related systemic sclerosing disease (IRSSD) is a new clinical entity that is characterized by elevated levels of serum IgG4; plasma cell infiltrates in tissues, including the pancreas, lung, liver, kidney and breast; and a good response to corticosteroid therapy. We report a case of a patient with sclerosing cholangitis and pulmonary inflammatory pseudotumors. The diagnosis was made twelve...

BACKGROUND Inflammatory pseudotumors can affect any organ, whereas primary omental tumors are very rare. A few cases have been reported in the literature, all affecting adult patients. They are usually difficult to diagnose preoperatively and pathology remains the criterion standard for diagnosis. Surgical resection is considered the first-line treatment in limited disease, whereas recurrent or...

Gallbladder polyps are seen on as many as 7% of gallbladder ultrasonographic images. The differential diagnosis for a polypoid gallbladder mass is wide and includes pseudotumors, as well as benign and malignant tumors. Tumefactive sludge may be mistaken for a gallbladder polyp. Pseudotumors include cholesterol polyps, adenomyomatosis, and inflammatory polyps, and they occur in that order of fre...

Inflammatory pseudotumors (IPT) are soft tissue tumors that include a diverse group of lesions characterized by inflammatory cell infiltration and variable fibrotic responses. Idiopathic orbital inflammatory pseudotumors (IOIP) are IPTs of unknown etiology that develop in the orbit. Due to the lack of well-defined pathogenic mechanisms, diagnosis and treatment of this disease remain a significa...

OBJECTIVE To describe the clinical manifestations and types of, and our surgical experience with, neoplasms in the region of the temporomandibular joint (TMJ) in pediatric patients. MATERIALS AND METHODS From September 1997 to December 2013, a total of 18 patients with neoplasms in the region of the TMJ were treated at our department. They all underwent open surgeries. The clinical manifestat...

INTRODUCTION It has been reported that immunoglobulin G4-related systemic disease can spread to nearly every organ, and often presents as an inflammatory mass or masses at those sites. In the kidney, this disease is often diagnosed after a radical or partial nephrectomy following the discovery of an inflammatory mass which is often suspected to be a malignant tumor. Here, we present a rare case...

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...

The aim here was to report a case of a young adult patient who evolved with tumor formation in the left thigh, 14 years after revision surgery on hip arthroplasty. Davies in 2005 made the first description of this disease in patients undergoing metal-on-metal hip arthroplasty. Over the last decade, however, pseudotumors around metal-on-polyethylene surfaces have become more prevalent. Our patie...
