Myxoid Liposarcoma of the Parotid Gland.

Liposarcoma is extremely rare in the parotid gland. In this article, we report the case of an 87-year-old man who presented to our department with swelling in the left parotid region. Magnetic resonance imaging (MRI) revealed a tumor in the superficial lobe of the parotid gland. Total parotidectomy and ipsilateral lymph node dissection were performed. Histologic examination confirmed the diagnosis of myxoid liposarcoma of the parotid gland. On imaging, there was no evidence of nodal or distant metastasis. Radiation therapy was planned, but the patient refused to receive treatment. After a follow-up of 3 years, MRI showed no sign of tumor recurrence and the patient remained symptom-free. The case is original by the tumor's location. Only 8 cases of primary parotid liposarcoma have been reported in the literature. The purpose of this article was to discuss, through our case, clinical and anatomopathological features of parotid gland liposarcomas as well as its treatment options and prognosis.

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. Clinical examination objectified a right testicular induration. Macroscopic examination of the orchidectomy objectified a paratesticular solidocystic tumor formation. Microscopically, the solid area was composed of vessels with small caliber and turgidity of endothelial cells. These vessels were surrounded by clusters of epithelioid cells, sometimes having the appearance of giant cells. They were associated with spindle cells. The cystic area was uncoated. Immunohistochemically, the fusiform cells expressed Desmin and Smooth Muscle Actin. Endothelial cells and clusters of cells surrounding large vessels expressed CD34. The expression of receptors for estrogen and progesterone was negative. To our knowledge, this is the second solidocystic case of angiomyofibroblastoma-like tumor of male genital tract.

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

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. The lesion was completely resected and microscopic study showed mildly thickened bone trabeculae and multivacuolated brown fat cells replacing the normal white fat and hematopoietic elements. The diagnostic of intraosseous hibernoma was made. CONCLUSION: Although it is rare, hibernoma should be included in the differential diagnosis of lipomatous  tumors.

[Prognostic value of markers of aggressiveness of urinary bladder tumours evaluated by immunohistochemistry]. / Valeur pronostique des marqueurs d'agressivité des tumeurs vésicales évalués par immunohistochimie.

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. results: The expression of PCNA with a cut-off value of 14% is correlated with recurrence (P = 0.010). The expression of PCNA with a cut-off value of 1% is correlated with tumour stage (P = 0.003). The expression of MIB1 with a cut-off value of 47% is correlated with recurrence (P = 0.010). The expression of MIB1 with a cut-off value of 47% is correlated with the tumour progression in stage and\or in grade (P = 0.007). The expression of C-erbB2 with a cutoff value of 28% is correlated in the tumour grade (P = 0.007). The other antibodies didn't demonstrate a prognostic value. CONCLUSION: MIb1 and PCNA being correlated with recurrence, they can be useful with the decision of the rhythm of the endoscopy. The correlation of C-erbB2 with the tumour grade could serve to better graduating bladder tumours.

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. In addition, the clinical findings are by no means specific to a tumour type and cannot distinguish between a benign and a malignant tumour, which results in difficulty in diagnosis and management. All paratesticular tumours are amenable to adequate surgical resection. Definite diagnosis is determined by histological evaluation.Leiomyosarcoma, the second most common paratesticular sarcoma after liposarcoma, is represented in the literature primarily as case reports. We report a case of LMS arising from the epididymis and focus on clinical presentation and differential diagnosis of such tumours.

[Idiopathic portal hypertension associated with celiac disease: one case]. / Hypertension portale idiopathique associée à une maladie coeliaque: à propos d'un cas.

We describe for the first time a case of idiopathic portal hypertension (IPH) in a 31 year old patient with coeliac disease (CD). She had splenomegaly, pancytopenia and an unexplained portal hypertension in the absence of any histological abnormalities of the liver. The diagnosis of coeliac disease was based on histological and serological data. Treatment included a splenectomy and a splenorenal shunt.
