[Endometrial adenofibroma].

We report a case of papillary adenofibroma of the uterine corpus in a 31 year-old woman who was initially examined for vaginal bleeding. Pelvic examination showed a large polypoid mass protruding through the cervix canal. A pelvic ultrasound revealed a polypoid cystic mass apparently arising from the uterus. A polypectomy was performed. The tumor was composed histologically by begin epithelial and mesenchymal components. Uterine adenofibroma is a extremely rare tumor which considered to be a mixed tumor of Müllerian origin. This lesion appears to be clinically and histologically benign but must be differentiated from other malignant lesions of the uterus, particularly from the adenosarcoma.

[Intestinal lymphoma associated with Behçet disease].

The association of Behçet's disease and non-Hodgkin's lymphoma is very rare. The first case of primary intestinal lymphoma with intestinal Behçet's disease is reported. A 37 year-old woman had been treated for Behçet's disease with colchicine for 2 years. In July 1997, she developed uveitis and was treated by monthly intravenous pulses of cyclophosphamide for 6 months, but uveitis persisted; so cyclophosphamide was replaced by cyclosporin 300 mg/day. One month later, she suffered from diarrhea. Colonoscopy showed ileocoecal ulcerations. Histological examination of surgical biopsy revealed B large cell type lympocytic malignant lymphoma and vasculitis lesions compatible with intestinal Behçet's disease. Cyclosporin was stopped and treatment with prednisone was instituted. The relationship between non-Hodgkin's lymphoma and immunosuppressive drugs in Behçet's disease is discussed.

[Behçet's disease associated with Crohn's disease].

INTRODUCTION: The association of Behçet's disease and of Crohn's disease is exceptional, and raises a nosological problem. CASE REPORT: A 24 year-old female developed since 1996 chronic diarrhea, abdominal pain, recurrent oral and genital ulcer and polyarthralgia. Endoscopic colonoscopy examination showed a diffuse colitis. Histological examination revealed epitheloid granuloma without vasculitis compatible with a Crohn's disease. The patient was treated with oral prednisone (1mg/kg/day). In November 1998, she was admitted for diarrhea. Many pseudofolliculitis lesions, uveitis and positive pathergy test were noted. The HLA was B 51. The diagnosis of Crohn's disease associated with Behçet's disease was made. She was treated with high doses of prednisone (1mg/kg/day and 6 monthly intravenous pulses of cyclophosphamide). Skin lesions and diarrhea improved within few days, and cleared completely within five months. Presently, the patient remains clinically free of disease. CONCLUSION: While being of different pathogenic origin, Behçet's disease and Crohn's disease may coexist within one and the same patient and cause diagnostic and therapeutic problems.

Mesenchymal extraskeletal chondrosarcoma of the orbit. Report of a case and review of the literature.

BACKGROUND: Extraskeletal mesenchymal chondrosarcoma (MCS) is relatively uncommon. Orbital location is extremely rare: only 16 cases have been reported until now. We report a case of extraskeletal mesenchymal chondrosarcoma in a 27-year-old man and review the literature on its manifestations and management. CASE REPORT: This patient had a 2-year history of progressive proptosis of the right eye. Skull X-ray and CT scan showed intraorbital calcification and a large lesion in the upper right orbit. He was operated three times because of recurrence of the tumor. The last recurrence was observed to have extension to the intracranial region, detected on MRI and CT scan. This secondary extension of the tumor to the intracranial region has not been previously reported. Immunohistochemical analysis for S-100 protein showed focal positivity. CONCLUSION: Mesenchymal chondrosarcoma of the orbit is rare, and secondary extension to the intracranial region has not previously been reported.

[Primary gastric MALT lymphoma in children. Report of 2 cases].

Primary gastric MALT non-Hodgkin's lymphoma is rare in immunocompetent children. To our knowledge, only two cases have been previously described. We report two cases of gastric MALT lymphoma associated with Helicobacter pylori. Clinico-pathological features are similar to those observed in adults. The relationship between the microbial infection and non-Hodgkin's lymphoma development is discussed.

[Testicular non-Hodgkin's lymphoma. Report of 2 cases].

We report two cases of non Hodgkin malignant lymphoma of the testis observed in two patients 36 and 32 years old. Diagnosis was made on pathological examination after orchiectomy. One patient had an involvement of the lung and Waldeyer's ring and the other presented cerebral involvement. Despite combination chemotherapy and external beam radiation therapy, the disease progression was rapid and fatal in the first patient (19 months) while the second had multiple cerebral relapses and died by disease progression 21 months after orchiectomy.

[Paraganglioma of the cauda equina. Apropos of a case with review of the literature].

Paragangliomas are unusual neuroendocrine tumors. The most common anatomical site is within head and neck (90%). It has rarely been described in the region of the cauda equina. We report the case of a 49 years-old white woman who presented with a slow, progressive cauda equina syndrome over a 20-years period. Radiological examination showed erosion of the vertebral laminae of L4, L5 and S1 and disclosed an intra-dural mass lesion occupying the entire spinal canal between L4 and S1. The patient underwent sub-total excision and adjuvant radiation therapy. Histological examination concluded to a paraganglioma. This diagnosis was confirmed by immunohistochemical studies.

[Synovial lipoma arborescens].

The synovial lipoma are uncommon articular tumors of unknown origin. We report two cases of synovial lipoma arborescens arisen in a man and a woman respectively 41 and 27 years old. Both had already consulted for a tumefaction progressively increasing in volume. It was accompanied in the first case by a laxity in the knee joint. Radiography and arthroscopy showed an important hyperplasia of the articular synovia. A total synovectomy was performed in both cases. The synovia had a hairy aspect and was extremely thickened. It weighted 1.5 kg in the first case and its section had a fatty aspect. The histological examination confirmed the diagnosis of synovial lipoma arborescens. The observed aspect of the two tumors and particularly their volume, which was very important in the first case are arguments in favor of their tumoral nature.

[Pseudotumoral abdominal cysto-steato-necrosis: an unusual etiology].

We report an unusual case of subcutaneous pseudo-neoplastic focal fat necrosis in a woman with a Mersilen plate placed outside the abdominal wall muscles. To our knowledge, this association has not been previously reported in the radiologic literature. The differential diagnosis using ultrasound and computerized tomography is discussed.

[Tumors of the ceruminous glands].

Tumors of ceruminous glands, called "ceruminoma" are rare. They arise from the ceruminous glands of the external auditory canal. They realise a group of glandular tumors diversified in histologic pattern and prognosis. Three patients with ceruminous gland tumors are reported: one case of ceruminous adenoma, one case of adenocarcinoma and adenoid cystic carcinoma in the third one.

[Fibrous inflammatory polyp of the digestive tract. Apropos of 5 cases].

Inflammatory fibroid polyp is a rare benign tumor of the digestive tract. The authors report three cases: two intestinal and one gastric. These cases are of particular interest because of the association ill one case of an intestinal submucosal lipoma with the inflammatory fibroid polyp, and the existence in the gastric case of an inflammatory reaction caused by food debris. This offers, further evidence in support of the theory implicating a chronic inflammatory reaction.

[Collagenous enterocolitis. Apropos of a case and review of the literature].

Collagenous enterocolitis is a recent entity of which only two cases have been published. The authors report the association of collagenous colitis and collagenous sprue in a 67-year-old woman. The diagnosis of collagenous enterocolitis is based on the presence of a duodenal collagen deposit with partial villous atrophy associated with collagenous colitis. The symptom appeared one month after non-steroidal antiinflammatory treatment. The authors discuss the role of drug toxicity in the pathogenesis of collagenous enterocolitis.

[Total septate uterus with hemi-vagina and homolateral renal dysplasia].

We report a rare case of uro-genital malformation in 18 years old girl. The malformation associate total septus uteri, hemivagina atretica dextra and homolateral dysplastic kidney. Dysmenorrhea, purulent discharges from cervix and vaginal tumor evocated the diagnosis, which was confirmed by ultrasonography, hysteroscopy and coelioscopy. Therapeutic attitude was total resection of vaginal septus and right nephrectomy. At today, seven cases were published in international literature. In all cases, renal aplasia was reported. Embryologic acknowlegements can't explain this malformation.
