Supplementation of grape seed and skin extract to orlistat therapy prevents high-fat diet-induced murine spleen lipotoxicity.

Spleen is the largest lymphoid organ and obesity is related to an elevated risk of immunity dysfunction. The mechanism whereby fat adversely affects the spleen is poorly understood. This study was designed to assess the effectiveness of grape seed and skin extract (GSSE) and orlistat (Xenical, Xe) on high-fat diet (HFD)-induced spleen lipotoxicity.

Intraosseous hibernoma: a case report and review of the literature.

Unlabelled: Intraosseous hibernoma is a rare benign bone tumor, with only 4 cases reported in English literature.

Case Report: In this report, we describe a 42-year-old man with  no past medical history and right chest pain. Imaging studies showed an osteolytic lesion with fat attenuation lesion in the right fourth rib.

Digestive neuroendocrine tumors: reclassifying of 26 cases according to 2010 who classification.

Background: The classification of digestive neuroendocrine tumors is difficult due to their heterogeneity and rareness.

Aims: Reclassify the digestive neuroendocrine tumors according  to  the  WHO-2010 classification .  Methods: A retrospective study included   26 patients having digestive neuroendocrine     tumors ,  is achieved  in our  Pathology  Laboratory  of the Military Hospital of  Tunis between 2000 and 2013.

Paratesticular Angiomyofibroblastoma-Like Tumor: Unusual Case of a Solidocystic Form.

The angiomyofibroblastoma-like tumor of the male genital tract is a rare benign tumor. A total of 34 cases have been reported in the literature. We herein report an exceptional case of solidocystic form in its paratesticular location, in a 79-year-old man.

Reclassification of gastrointestinal mesenchymal tumors.

Background: Gastrointestinal stromal tumors - commonly called GISTs - are rare; yet, they represent an important type of mensenchymal tumors arising within the gastrointestinal tract. The acronym GIST was introduced in 1998 to define a well established pathological entity which bears a highly specific marker called KIT (CD117). Scientific interest for these tumors in recent years is mainly due to the progress in identification by immunohistochemistry and the advent of targeted molecular therapy.

[Prognostic value of markers of aggressiveness of urinary bladder tumours evaluated by immunohistochemistry].

Background: The study of some immunohistochemical markers provides an objective and reproducible prognostic evaluation of urinary bladder tumour. aims: study the expression of the following immunohistochemical markers in Tumours of the bladder: Proliferating Cell Nuclear Antigen (PCNA), Ki67 antigen (MIB1), the C-erbB2 proto- antigene, the tumor suppressor gene p53, the receptor for epidermal growth factor (EGF-R), the apoptosis suppressor gene bcl2, the carcinoembryonic antigen (CEA) and epithelial membrane antigen (EMA). methods: Study of retrospective series of 30 patients having tumours of the urinary bladder.

A rare cause of a scrotal mass: primary leiomyosarcoma of epididymis.

Most masses encountered within the scrotal sac are neoplastic and occur within the testis; however a subset (2-3%) of these tumours is extra-testicular and usually arises from paratesticular tissue. Although uncommon, these tumours have a high incidence of malignancy reaching 30%, mainly represented by sarcomas (90%). Tumours occurring in the paratesticular region may be clinically indistinguishable from testicular tumours, thus resulting in initial misdiagnosis.

Giant condyloma (Buschke-Löwenstein tumor). A case report.

Buschke-Löwenstein tumor (BLT), or giant condyloma acuminatum, is a rare sexually transmitted disease. The virus responsible for condyloma is human papillomavirus, usually serotype 6 or 11. A BLT is always preceded by condyloma acuminatum and may occur at any age after puberty.

[Inflammatory pseudotumor of the spleen: two case reports].

Inflammatory pseudotumor (IPT) of the spleen is an uncommon entity with debated etiology, characterized by a mixture of inflammatory cells and a component of myofibroblastic spindle cells. This lesion needs to be distinguished from the follicular dendritic cell tumor and the inflammatory myofibroblastic tumor. We report two cases of splenic PTI in a 69-year old and a 62-year old women.

Acute renal failure due to lymphomatous infiltration: an unusual presentation.

Renal lymphoma occurs most often as a part of a multi-systemic disseminated lymphoma or as a recurrence of the tumor. Renal involvement usually occurs late in the course of the disease and is clinically silent. Acute renal failure (ARF) from lymphomatous infiltration has been described but is quite rare.
