Benign perivascular epithelioid cell tumor (PEComa) of the lung is a rare benign neoplasm, a sclerosing variant of which is even rarer. We present a case of 51-year-old man who was diagnosed with benign sclerosing PEComa by percutaneous fine needle aspiration cytology and biopsy. The aspirate revealed a few cell clusters composed of bland-looking polygonal or spindle cells with fine granular or...

We describe the case of an 18-year-old female with Cowden syndrome in whom a simple x-ray detected a solitary pulmonary nodule that was identified as a sclerosing hemangioma. Pulmonary sclerosing hemangioma is an unusual lung neoplasm which typically presents as a solitary peripheral nodule in asymptomatic women. Although the histology of this entity is well defined, its origin and treatment is...

It has been well documented that autoimmune pancreatitis (AIP) [1], also known as sclerosing pancreatitis [2], is frequently associated with fibrosclerotic diseases, such as Sjögren’s syndrome [3,4], primary biliary cirrhosis [5], primary sclerosing cholangitis [3–5] or retroperitoneal fibrosis [6]. However, as yet, there have been no reports on renal complications of AIP, except for hydronephr...

Sclerosing hemangiomas of the lung are benign neoplasms of uncertain histogenesis. We analysed two cases of sclerosing hemangiomas of the lung with histochemistry and electron microscopy. They had a variegated histologic appearance characterized by an admixture of solid, hemorrhagic, papillary and sclerotic lesions. Characteristic uniform round cells, unique to this tumor, were found within the...

Sclerosing cholangitis and cholestatic jaundice secondary to metastatic disease is a rare complication. We report a rare case of secondary sclerosing cholangitis (SSC) due to lymphatic spread from ovarian cancer with complete resolution after chemotherapy. The diagnosis of SSC from metastatic ovarian cancer was clinically challenging, as endoscopic retrograde cholangiopancreatography revealed i...

Primary sclerosing cholangitis is a chronic progressive disorder which involves the medium size and large ducts in the intrahepatic and extrahepatic biliary tree. The great majority of cases have underlying inflammatory bowel disease, mainly ulcerative colitis. A higher risk of colorectal cancer has been described among ulcerative colitis patients with primary sclerosing cholangitis. Here we re...

Sclerosing stromal tumor (SST) is an extremely rare and distinctive sex cord stromal tumor which occurs predominantly in the second and third decades of life. We report a case of a 32-year-old woman who developed a sclerosing stromal tumor of ovary and presented with irregular menstruation and pelvic pain. Her hormonal status was normal but CA-125 was raised. She was suspected to have a maligna...

conclusions a comparison of our results with those obtained from other centers in both western and asian countries (which reported cca in 3.6% - 36.5% of patients with psc), shows that the incidence of cca in the patients we studied is intermediate. results of the 181 patients, 16 were found to have cca, two of whom had been diagnosed after pathologic study of the explanted livers. therefore it...

osteomyelitis is an inflammatory infectious condition of bones, occurring either acutely or chronically. the clinical course of the disease leads to destructive or sclerosing patterns of the involved bone. this report presents a case of chronic focal sclerosing osteomyelitis in a 19-year-old male with a history of an uncontrolled convulsive condition. the lesion was first diagnosed as an osteob...
