Epithelioid hemangioma of bone is a rare benign vascular lesion. Since its first description by Rosai in 1979 about thirty cases have been reported. We report two new cases diagnosed in patients aged 21 and 7 years. Both patients had multiple lesions on the legs. Bone pain was the main symptom. Routine laboratories studies were unremarkable.

Hemangiopericytoma (HPC) of the orbit is a rare tumor presenting with slowly progressive proptosis, ocular motility impairment and visual loss. In 1995, a newly variant of HPC termed lipomatous hemangiopericytoma (LHPC), was described. Only two cases arising in the orbit have been previously reported. The authors describe another case of orbital LHPC and(More)
UNLABELLED Mucormycosis is caused by a zygomycetes fungus in a vascular location. This fungus is a saprophytic organism which can become pathogenic in specific conditions, particularly in patients with diabetes mellitus. A rhinocerebral localization is common, leading to often fatal devastating sinusitis. Positive diagnosis requires histological proof with(More)
An extremely drug-resistant Enterobacteriaceae species emerged in Kasserine Hospital, Tunisia between 2009 and 2010 causing a local outbreak. We aimed to characterize extended-spectrum β-lactamase (ESBL) and metallo-β-lactamase (MBL)-producing Enterobacteriaceae from the hospital environment. Swabs were collected from ten different wards from Kasserine(More)
Gastrointestinal stromal tumors (GIST) are mesenchymal tumors that arise from the wall of the gastrointestinal tract expressing CD117 and/or the CD34. Similar tumors were described in the soft tissue of the abdomen and are so-called extragastrointestinal stromal tumors (EGIST). We report 4 new cases of EGIST. The tumors occurred in 2 women and 2 men, who(More)
Most hemangiopericytomas (HPC) are located in the musculoskeletal system and the skin, while the location in the central nervous system (CNS) is rare. The latter represents 2 to 4% in large series of meningeal tumors, thus accounting for less than 1% of all CNS tumors. In the central nervous system, tumors with a hemangiopericytomatous histolopathological(More)
AIMS To study the immunohistochemical expression of HHV8 in Kaposi's lesions and in other vascular lesions and to determine the utility of this technique in differentiating between Kaposi's disease (KD) and other vascular lesions. METHODS Fixed, paraffin-embedded tissue sections from 25 cases of KD, 9 cases of hemangioma, 2 cases of angiolymphoid(More)
