[Adrenal pheochromocytoma. Report of six cases].

The authors report 6 cases of adrenal pheochromocytoma seen over a period of 3 years (1993-1995). All patients were females, aged between 17 and 43 years with a mean of 35 years. Clinical manifestations consisted of either sustained hypertension, with episodes of hypersudation and palpitations, or paroxysmal hypertension which was revealed during surgery ; the disease was sometimes discovered incidentally. C.T and ultrasound showed in every cases adrenal mass as 3 to 6 cm usually located on the left side (5 cases). All patients were operated via lumbotomy and adrenalectomy was performed. In one case an associated thrombus within the vena cava was removed. Postoperative follow-up was uneventful except for one patient who developed a recurrent episode of hypertension.

[Renal needle biopsy in children. Technical aspects and results].

Renal needle biopsy is still irreplaceable in children. The objectives of this retrospective study were to specify the technical aspects and the main nephropathies encountered. 152 children under the age of 16 years (13 +/- 3), 79 boys and 73 girls, underwent renal biopsy. The biopsy was performed after radiographic detection in 71 cases, and under continuous ultrasound guidance in 81 cases. The comparative study of these 2 techniques revealed the superiority of continuous ultrasound guidance, allowing biopsy of an essentially cortical fragment, rich in glomeruli with a limited number of punctures. Histological examination showed a predominance of glomerular nephropathy with, especially, visually normal kidney and membranoproliferative glomerulonephritis. These data encourage us to perform ultrasound-guided RNB in children and to eradicate sites of infection, particularly involving the upper respiratory tract.

[Cancer of the testis in cryptorchidism. Apropos of 5 cases].

Five cases of cancer of the testicle in patients with cryptorchidism are presented. In one case the tumour occurred 16 years after cure for cryptorchidism at 15 years of age. In the other cases, the tumour developed on a testicle in an inguinal or intra-abdominal position. In two cases, it was impossible to remove the tumour which had developed on an intra-abdominal position. These patients died. These cases emphasize the importance of surgical cure in all cases of cryptorchidism, preferable before the age of 2 years, in order to improve functional prognosis and reduce the risk of cancerization. The gravity of cancer of the testicle in cases of cryptorchidism is often discovered too late.

[Male internal pseudohermaphroditism or a man with a uterus].

Mullerian structures were discovered during cure of bilateral ectopic testes in a 14-year-old boy. The original feature of this case was the presence of both testes on the same side. The Mullerian structures were left in place as they were intimately adherent to the vas deferens. This attitude was adopted as no degeneration of these structures has been described and because of the possibility of reproduction of these patients during adulthood.

[Bone hydatidosis. 12 cases].

The hydatic cyst is a parasitic disease caused by the development in man of the larval form of echinococcus granulosus. All parts of the body may be involved, but the liver and lungs are the main locations of the disease. The bone site is rare, accounting for 0.9 to 2% of all hydatic lesions. Between 1982 and 1988, we have compiled 12 cases of hydatic disease of bone. They were located in the skull (4 cases), the iliac bone (4 cases), the omoplate (1 case), the ribs (1 case), the femur (1 case) and the fibula (1 case). These lesions are generally considered as primary, but association with visceral locations was noted in 3 cases in our series.

[Hemangioma of the renal calyx].

A case of renal hemangioma in a child is reported. The patient presented with severe painless hematuria. Intravenous pyelography showed a filling defect in the middle calyx of the right kidney. Ultrasonography showed a hypoechoic zone in the renal sinus. Hematuria was unilateral on right side at cystoscopy. Total nephrectomy was performed. The diagnosis was confirmed by histology.

[Carcinosarcoma of the urinary bladder and renal metastasis].

A 74 year-old woman developed a polypoid tumor of the bladder which was discovered by hematuria. Upon histological examination, the tumor was shown to be a carcinosarcoma with a weak epithelial composition confirmed by immunolabelling with keratin and was composed essentially of chondrosarcomatous material. Six months later, the patient developed metastases in the kidney, in the paravertebral muscles, and in the right para-ureteral lymph nodes. There are 55 cases of carcinosarcoma of the bladder described in the literature [3, 20, 22]. It is a tumor found more frequently in men than in women, between the ages of 33 to 83. The prognosis is very gloomy .70% death rate within 2 years), but it seems to be improved by radical cystectomy and adjuvant therapy.

[Bilateral brown tumor of the jaw. Apropos of a case].

A 42 years old woman was seen October 1987 because of tumor on the left maxilla. Removal of the lesion and histologic examination conclude at myeloplaxe tumor. A second giant cell lesion appears in the right maxilla 2 years later. The diagnosis of brown tumor was confirmed by the discovery of a parathyroid adenoma. We discuss about this case diagnosis difficulty of brown tumor from the others giant cell lesions of the jaws.

[Extra-adrenal pheochromocytoma. Report of two cases].

Paraganglioma is rare neoplasm. The authors report two new cases. The first case was a 36 year-old woman who presented with post-micturitional episodes of hypertension. Radiologic and endoscopic investigations showed a left submucosal bladder neck tumor. A partial cystectomy was performed under neuroleptanalgesia. The postoperative course was uneventful is simple. The second case was a 61 year-old woman who presented with a non secreting para-aortic paraganglioma.

[Confluent tuberculomas of the vermis cerebelli associated with an occipital localization. Report of a case and review of the literature].

An unusual case of multiple cerebral tuberculomas is reported. The patient, a 19-year-old woman, presented with a 6-month history of raised intracranial pressure and cerebellar symptoms. CT scan disclosed a conglomerate of several ring-enhancing lesions within the cerebellar vermis and another homogeneously enhancing mass against the right occipital horn. Solid and ring-enhancing lesions are the main mode of presentation of cerebral tuberculomas. Although the patient had no history of systemic tuberculosis, this diagnosis was considered highly probable in this geographic area and was confirmed by pathological examination of the cerebellar mass, the excision of which was considered necessary. Antitubercular medications led to complete regression of the associated occipital lesion, as demonstrated by sequential CT scan examinations.

Collagenous colitis: histologic, morphometric, immunohistochemical and ultrastructural studies. Report of 21 cases.

We examined 129 colonic biopsies from 21 patients with collagenous colitis, most of whom presented with diarrhoea. Morphometric measurements gave a mean thickness of the subepithelial collagen deposit of 19.5 mu +/- 5.1. The trapped fusiform and/or stellate cells within the deposits were identified immunohistochemically as myoid cells, being positive with antibody against smooth muscle cell alpha-actin. Ultrastructurally, these cells have all the characteristic features of myofibroblasts. Similar cells are also present along the crypts, where they were formerly referred to as pericryptal fibroblasts. Although there is still much debate as to the pathogenesis of this condition, we would like to suggest that collagenous colitis is a disease of pericryptal myofibroblasts. During their migration and maturation into the subepithelial region they may synthesize an excess of collagen, under some yet unknown or undefined stimulus/stimuli.

[Histological study of a case of chondrocostal aspergillosis].

Histological study of biopsy specimens successively taken from the 7th, 5th and 6th right chondrocostal regions in a 33 year-old man; the patient was under chemotherapy for a diffuse lymphoma and has been operated for an aspergilloma of the right lung superior lobe. Non-specific chronic osteomyelitis was observed as well as Aspergillus fumigatus perichondritis (acute and chronic) which had lead to cartilage fragmentation. Cartilage fragmentation could be attributed to an enzymatic chondrolysis induced by polymorphonuclears inflammation. Such matrix degradation seems to favour the penetration of aspergillus into the cartilage surface. This case report recalls that fungi (including Aspergillus despite it appears exceptional) must be considered as a possible cause of osteomyelitis, particularly in immunosuppressed patients.
