A case of spinal immature teratoma.

We report a rare case of intradural immature teratoma in 2-year-old girl, interesting conus medullaris to sacrum, worsening neurological deficits. The neoplasm discovered by magnetic resonance imaging, was completely resected. We describe the clinical, radiological and pathological findings of this tumor with a review of the Literature and we insist in the difficulty of treatment.

Primary invasive micropapillary carcinoma of the colon: case report and review of the literature.

Invasive micropapillary carcinoma is associated with frequent lymph node metastases and adverse clinical outcome. It has been reported in breast, urinary bladder, lung and the parotid gland, but very rarely in the colon. We report a new case in a 63-year-old man involving the colon, and discuss the clinicopathologic features of this rare and particularly aggressive tumour.

A history of partial complex seizures in a 30-year-old woman.

Dysembryoplastic neuroepithelial tumour is an uncommon lesion of the brain characterised by a heterogeneous population of neurons, astrocytes and oligodendroglia-like cells. Most patients are young adults with a long history of drug-resistant seizures. We report a case of a 31 year-old woman with a history of severe epileptic attacks.

[Solitary fibrous tumor of the nasal cavity: an observation report].

Solitary fibrous tumour is a rare mesenchymal tumour first described in the pleura, but can involve other serosal surfaces and viscera. In the nasal cavity, it is extremely rare. We report a new case in 90-year-old man and discuss the morphologic and evolutive features.

Renal mucinous tubular and spindle cell carcinoma.

We report a case of mucinous tubular and spindle cell carcinoma in a 66-year-old woman. The tumour, located on the left kidney, was well circumscribed. Microscopically, the tumour was composed of cuboidal cells arranged in tubules and making abrupt transitions to spindle cell morphology in a myxoid stroma.

Malignant proliferating trichilemmal tumor of the scalp: a case report.

Background: Malignant proliferating trichilemmal tumor is a rare skin tumor that affects mainly older women. It mimicks differential squamous cell carcinoma and its biological behavior is unpredictable.

Objective: To report on a new case of malignant proliferating trichilemmal tumor of the scalp and to describe the clinical and histopathologic findings.

Micropapillary carcinoma of the urinary bladder: a case report and review of the literature.

Micropapillary carcinoma is an uncommon variant of urothelial carcinoma with high metastatic potential. The presence of micropapillary carcinoma component in bladder biopsies should alert urologists to its aggressive behaviour. We report the case of a 70-year-old man who presented with macroscopic hematuria lasting 2 weeks.

Collision epithelial and stromal tumours of the stomach: a case report.

Collision epithelial and stromal tumours of the stomach are uncommon, and only a few cases have been reported in the literature. We describe a new case of a 54-year-old man who presented with bloody emesis. An oesophagogastroduodenoscopy revealed a stomach induration, and preoperative histological diagnosis was signet ring carcinoma.

[Detection of Epstein-Barr virus in breast cancers with lymphoid stroma].

Objective: the purpose of our work is to detect Epstein-Barr virus (EBV) in 2 types of breast cancer: medullary carcinoma and high grade invasive ductal carcinoma with lymphoid stroma.

Patients And Methods: we proceeded to a retrospective study of 18 medullary carcinoma and 18 high grade invasive ductal carcinoma with lymphoid stroma. The detection of the virus was carried out by immunohistochemistry with anti-LMP2 antibody and by hybridization in situ by oligonucleotides EBER1 and EBER1.

Primary mesenteric sertoli-leydig cell tumor: a case report and review of the literature.

The occurrence of primary sex cord-stromal tumors at extraovarian sites is exceedingly rare. We report a new case of Sertoli-Leydig cell tumor in the mesentery of a 78-year-old woman who presented with occlusive syndrome and reviewed the previously reported cases of extraovarian sex cord-stromal tumors in the English literature.

Metastatic liposarcoma to the parotid.

Distant metastases of the parotid gland are uncommon. They arise from primary tumors located in the head and neck, mainly melanoma and epidermoid carcinoma. Other histological types of metastasis are very rare.

[Myoepithelial carcinoma ex-pleomorphic adenoma of the parotid gland].

Introduction: Myoepithelial carcinoma accounts for less than 1% of salivary gland malignant tumors. It may develop de novo or, in approximately 50% of the cases, from a pleomorphic adenoma.

Observation: A 57-year-old man with a history of a pleomorphic adenoma of the parotid treated surgically 6 years earlier, presented with a 2 cm tumor mass, palpable in the scar region.

[Mesenchymal tumors of the digestive tract, immunohistochemistry contribution].

Unlabelled: Mesenchymal tumors of the digestive tract are rare and display variable morphological appearances. Thanks to immunohistochemistry and molecular biology, these tumors are now better classified and dominated by stromal tumors.

Aims: the aim of this article is to study morphological characteristics of mesenchymal tumors of the digestive tract and to insist on immunohistochemistry contribution to diagnosis, especially the c-Kit.

[Extra-thoracic solitary fibrous tumor. Report of 2 cases].

The solitary fibrous tumor (SFT), is an unusual entity, first described in the pleura, but can involve other serosal surfaces and viscera. We report two cases of extra-thoracic SFT involving the retro-peritoneum and the upper arm. Extra-thoracic TFS is a rarily wide morphologic and evolutive spectrum.
