[Primary hepatic localization of the PPNET (primitive peripheral neuroectodermal tumors). Case report].

Our purpose is to study, through the case of a patient operated for right hepatic tumour, the clinical, radiological, anatomopathologic and therapeutic aspects of the peripheral primitive neuroectodermal tumours (PPNET). This tumour (PPNET) is a neoplasm belonging to the Ewing's family tumours, whose histology is similar. Its diagnosis requires the contribution of histopathology, immunohistochimy and cytogenetic studies. The primary hepatic localization of this rare tumour (our case), has never been reported. The treatment, in theory copied on that of the Ewing's sarcoma, is complex and not yet codified, which makes it another disappointing aspect of this disease whose prognosis remains dark.

[Tuberculosis of the thyroid. Diagnosis and treatment].

Thyroid tuberculosis is rare. We present the case of a 25 year-old woman with tuberculosis of the thyroid. Although seldom observed, tuberculosis should be considered in the differential diagnosis of nodular lesions of the thyroid. Diagnosis is made by histological examination and demonstration of the tubercle bacilli from biopsy or aspiration specimen. The efficacy of fine-needle aspiration cytology in diagnosis of tuberculosis of the thyroid is proved. Administration of antituberculous drugs is considered as the treatment of choice. Abscess drainage is sufficient. In rare cases surgery is necessary. The prognosis is good.

[Iterative surgery for goiter].

AIM: Identify and resolve problems related to iterative surgery for goiter. PATIENTS AND METHOD: Fifty-nine patients who underwent surgery for recurrent benign goiter between 1990 and 1999 were included in the study. RESULTS: Forty-two patients had lobectomy and isthmusectomy (71.2 and 17 patients had subtotal thyroidectomy (28.8%). The delay from initial surgery to recurrence was less than 5 years for 44% of the patients and was more than 10 years for 17.8%. There was no post-operative mortality and no recurrent laryngeal nerve injury. Early post-operative hypocalcemia occurred in 2 patients (3.3%). CONCLUSION: The goal of revision surgery for recurrent goiter is total thyroidectomy. Prevention is a rational management scheme for thyroid nodules.

Endoscopic ureteroneocystostomy: palliative urinary diversion in advanced prostatic cancer.

Distal ureteral obstruction is a common complication in advanced prostatic cancer, secondary to direct compression at the ureterovesical junction and/or invasion of the ureteral orifice and/or of the intramural ureter by the tumor. The ureteral orifice may not be readily visible to the trigone-infiltrating tumor, but remains superficial as it is pushed upward by the tumoral tissue. The indications for palliative diversion in patients with pelvic malignant disease and renal failure from ureteral obstruction remain controversial. We present the results of our endoscopic ureteroneocystostomy technique by which the trigone is resected to restore continuity of the ureteral orifice and to place a double pigtail ureteral stent. Of the 31 operations performed for obstructive prostate cancer, continuity was restored in 76% of cases. Length of hospital stay was gradually reduced to a few days. Median survival after surgery was 8 months (0.25 to 27.5 months). Palliative diversion may be considered a reasonable option for many patients, even in the case of an apparently unpassable obstruction of the pelvic ureter, thereby prolonging survival and improving quality of life.

[Retroperitoneal liposarcoma. Apropos of 2 cases].

We report two cases of retroperitoneal liposarcoma that required multiple surgical excisions for locoregional relapse diagnosed by surveillance based on CT-scan. One patient has had adjuvant radiotherapy. With the literature review, we discuss the pathologic and therapeutic aspects of these lesions.

[Cysts of the prostate. Apropos of 2 cases].

Two prostatic cysts have been diagnosed by us since 1993. The first patient presented with dysurial the second cyst was discovered incidentally. Transrectal ultrasound examination was useful for diagnosis. Treatment was a puncture--aspiration of the cyst in the first case, and abstention in the second one. A review, of the epidemiological, pathological and therapeutic aspects of the prostatic cysts is presented.

[Malignant adrenocortical tumors. Apropos of 9 cases].

The authors report 9 cases of adrenocortical carcinoma: 6 women and 3 men. 5 cases (55%) had a "nonfunctioning" tumor and 4 cases (45%) presented a clinical endocrinologic syndrome. According to the MacFarlane classification, patients were classified as: stage I: 1 case, stage III: 6 cases and stage IV: 2 patients. Adrenalectomy was performed in 7 cases. There was one postoperative death. 5 patients obtained clinical improvement.

[Results of endorectal MRI in local staging of prostatic cancer. Correlation with specimens from prostatectomy. Apropos of 47 cases].

Endorectal surface coil magnetic resonance imaging (MRI) was used in the local staging of prostate cancer in 47 patients. We used an 1.5 Tesla General Electric magnet. Fast spin echo sequences were acquired in all cases. All pathological specimen were reviewed by one pathologist. Pathological study showed that 19 patients had a locally confined cancer of the prostate (pT2), and 28 had an extraglandular extension (pT3). MRI correctly predicted a pT3 tumor in 15 of 28 cases, and a pT2 tumor in 18 of 19 patients. MRI was 70% accurate in the differenciation of stage pT2 from stage pT3 cancer. One case was overestimated and 13 cases were underestimated. The latter 13 patients had microscopic extracapsular invasion only.

[Herald's lesion with a localization in the bladder. Apropos of a case].

Herald's lesion located in the bladder is an non-specific extrinsic inflammatory lesion. This pseudotumoral neoformation often results from a pathologic process of the pelvis (95%). Recurrent cystitis is the main symptom. The diagnosis is difficult and cystoscopy and biopsy is the basic investigation. Surgical treatment must remove the original lesion with partial or total cystectomy. Epidemiologic, pathologic and therapeutic aspects of this disease are discussed.

[A rare variety of urothelial carcinoma. Apropos of 2 cases].

We report two cases of grade 1 papillary transitional cell carcinoma which have a distinct pathological. The tumor was infiltrating the lamina propria in the first case (pT1) and the superficial muscle in the second case (pT2). These tumors were composed by nests and tubules with few cytological atypias, making the diagnosis of cancer difficult. The prognosis of these tumors is not well defined.

[Severe algoneurodystrophy of the right foot associated with prostatic cancer].

The authors report 1 case of particularly severe reflex neurovascular dystrophy whose clinical course was marked by the discovery of a carcinoma of the prostate. There was improvement in the reflex neurovascular dystrophy despite hormonal therapy of the cancer. Reflex neurovascular dystrophy cannot be considered as a form of a paraneoplastic syndrome.

[Rare complications of the double-curved J ureteral stent].

The authors reported two cases of failure of the double-curved ureteral stent. The first is a spontaneous breakage and the second is migration downward and stone formation. The two polyurethane stend had been supported respectively 24 months and 15 months. The first case had been treated with endourology and the second with surgery.

[Xanthogranulomatous pyelonephritis. Apropos of 11 cases].

Xanthogranulomatous pyelonephritis is a rare manifestation of chronic pyelonephritis. 11 cases were treated between 1988 and 1993. Patients age ranged from 17 to 60 years (mean 34 j). A pseudotumoral form was documented in 3 patients and pyonephrosis was found in 8 cases. Urine culture was usually positive for a non specific germ. Imaging technics could differentiate pseudotumoral disease from diffuse disease. Treatment consisted in a nephrectomy.

[Treatment of stress urinary incontinence in women using the Goebell-Stoeckel surgical method. Study of 59 operated patients. Long-term review].

Stress urinary incontinence may be treated by different techniques. This study is based on a retrospective analysis of 59 patients treated between 1985 and 1993, by the Goebell-Stoeckel technique. 48 patients were questionned by phone in March 1995 to estimate the long term results. Two groups were defined; group A: follow-up between 15-60 months and group B: follow-up between 72-120 months (Total average follow-up: 68 months). The majority of patients were elderly, menopaused (88%) and had had one or more surgical procedure for incontinence (60%). Among 59 patients, 8 developped minor early complications. The mean length of hospital stay was 14 days and the mean duration of indwelling catheterization was 6.5 days. 60% of patients have had urinary retention after catheter ablation and have required intermittent catheterization at home for a mean duration of 14 days. Continence was achieved in 84% of cases at 3 months and had persisted in 96% of cases for group A and 91.5% of cases for group B. With a mean follow-up of 68 months, 37.5% of cases had irritative symptoms, 12.5% had minor urethral obstruction. 52% of patients obtained a very excellent result (normal continence, no urgency, no dysuria), 9% obtained an excellent result (normal continence, urgency with no leaked, and/or minor dysuria); 12 obtained a moderate result (normal continence, urgency with minor leakage without toilet set, and/or minor dysuria) and 27% obtained a poor result (incontinence, urgency with leakage necessitating toilet set, and/or dysuria).
