[Endometriosis with massive hemorrhagic ascites: a case report and review of the literature].

Endometriosis is defined as the presence of endometrial tissue outside the uterine cavity. It generally involves the peritoneum, ovaries and rectovaginal septum. Its characteristic symptoms include dysmenorrhea, pelvic pain, deep dyspareunia and infertility.

Hashimoto's thyroiditis associated with Riedel's thyroiditis and retroperitoneal fibrosis.

This article describe the case of a 38-year-old woman with simultaneous involvement of the thyroid by Hashimoto's thyroiditis and Riedels's disease, associated with retroperitoneal fibrosis and lipidic endarteritis. According to a large review of the literature on the occurrence of this rare condition the difficulty in sharply defining the two thyroid processes is discussed. The chronology of the events is analyzed, and etiopathogenic hypotheses are listed with emphasis on the relationship between the vascular lesions and the onset of the fibrosing process.

[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.

[Tumor of the spermatic cord and the gonadal stroma of the testis. Apropos of a case in a 19-year old man].

A Sertoli cell mesenchymal tumour was observed in a 19-year-old male. The prognosis of this rare tumour is good.

[Epidermoid cyst of the testis. Apropos of a case].

The epidermoid cyst of the testis, a rare and benign tumour, continues to create problems. Its definitive diagnosis remains a histopathological one and alters the prognosis and therapy. Based on their case report and a literature review, the authors discuss the different diagnostic, prognostic and therapeutic aspects of this lesion.

[Retroperitoneal benign schwannoma].

The authors report about one case of retroperitoneal benign schwannoma located near the right kidney and causing renovascular arterial hypertension. The diagnosis of benign schwannoma, which is unfrequent in the absence of Recklinghausen's disease, was established after the pathological study of the complete specimen including the right kidney.

[Clear cell unilocular and multilocular cystic renal tumors and in situ clear cell intratubular carcinoma].

Clear cell cyst can present as: multilocular cyst (mimicking a cystic nephroma), which is just a multicystic variant of clear cell carcinoma, the right diagnosis often being very difficult to make before final pathological examination; unilocular cyst with atypical clinical features, pathological diagnosis often being very difficult by cytology and on frozen sections; unilocular cyst resembling a simple renal cyst, that is usually small, found incidentally in kidneys removed for renal cell carcinoma (mostly clear cell carcinoma) or sometimes for another pathology. The discovery of this not infrequent type of clear cell cystic tumor was made possible only by systematic histological examination of all ordinary-looking renal cysts. A four year experience with a series of 255 kidneys is presented here.

[Unusual renal tumor in a young woman: cellular or atypical mesoblastic nephroma with partially cystic form].

A case of partially cystic atypical or cellular variant of mesoblastic nephroma in a 27-year old woman is reported. Nephrectomy was the only treatment. Since her operation, our patient has become pregnant and given birth to a healthy daughter.

[Cellular or atypical mesoblastic nephroma of partially cystic form. Apropos of a case in a 27 year old woman].

A case of partially cystic atypical or cellular variant of mesoblastic nephroma in a 27 year old woman is reported herein. Some of the cysts were like those seen in a cystic nephroma (solitary multilocular cyst) and others resembled ectasic vascular channels. Nephrectomy was the only treatment used.

[Cystic clear cell tumors of the kidney].

Renal clear cell carcinoma can sometimes present as: unilocular cyst; necrotic pseudocyst; multilocular cyst, resembling cystic nephroma. Diagnosis by cytology and on frozen sections is often difficult, or even impossible.

[Conservative treatment of a recurring retroperitoneal liposarcoma. Apropos of a case followed over 27 years].

We report about the case of a patient who, over 27 years, presented with seven local recurrences of a retroperitoneal liposarcoma. This evolution seems to characterize differentiated (adult and myxoid) forms of liposarcoma, for which metastatic expansion is less frequent that in the undifferentiated, pleiomorphic or round-cell forms. The treatment of these tumors is mainly surgical.

Genitourinary tumors and HIV1 infection.

4 patients with solid genitourinary tumors and HIV1 infection have been treated in our institution over the last 2 years. Two patients had seminoma, 1 renal adenocarcinoma and 1 renal angiosarcoma. All had deeply impaired immunity with a low CD4 level.

Immunohistochemical markers defined by monoclonal antibodies and response to bacillus Calmette-Guérin endovesical immunotherapy for superficial bladder tumors.

As bacillus Calmette-Guérin (BCG) immunotherapy is highly effective for most but not all superficial bladder tumors, there is a need to define predictors of response to this mode of treatment. We have investigated a panel of markers defined by monoclonal antibodies, directed against tumor-associated transitional cell carcinoma antigen (G4 and E7), epidermal growth factor receptor, cytokeratin (CK) 18 and blood group antigens A, B and H, using an indirect immunoperoxidase staining on paraffin sections. Twenty superficial bladder tumors (T1) treated with intravesical BCG therapy (10 responders and 10 nonresponders) were tested with this panel.

[Treatment of epidermoid carcinoma of the penis].

Epidermoid carcinoma of the penis is a rare type of cancer. Treatment of the primary lesion consists of amputation, although curietherapy can be effective in some cases as a conservative treatment. The prognosis is determined by the presence of absence of lymph node invasion, but the therapeutic strategy to be used when invaded lymph nodes are present remains controversial.

[Urogenital tumors and HIV-1 infection].

Four patients with solid genito-urinary tumors and HIV 1 infection have been treated in our institution over the last 2 years, including 2 with seminoma, 1 with renal adenocarcinoma and 1 with renal angiosarcoma. All had severely impaired immunity with a low CD4 level. Three had or developed a true AIDS syndrome according to the WHO and CDC criteria (1988).

[Pathological anatomy of adenocarcinoma of the prostate in 1988].

After going through gross and microscopic features of prostatic adenocarcinoma, the author stresses upon cytological diagnosis on fine-needle (Franzén) aspiration biopsies. Histological or cytological diagnosis may be difficult. And prostatic dysplasia is an especially difficult subject.

[Ultrasonic diagnosis of non-palpable germinal tumors of the testis. Apropos of 2 cases].

The germ cell tumors are the most common type of testicular malignant tumors (90%). About 30% are revealed by metastasis usually into the retroperitoneum, with clinically normal testis. Ultrasound reveals a bright echogenic focus into the testis which is typical, considering the clinical presentation, for a regressed germ-cell tumor and guides the side of the orchidectomy which allows to suppress a still active tumoral tissue which will not be eradicated by chemotherapy.

Bladder tumors: when to do and what to expect from random mucosal biopsies with reference to blood group cell surface antigens.

Routine random biopsies of normal looking bladder mucosa in the evaluation of bladder tumors demonstrated a high occurrence of anomalies ranging from dysplasia to carcinoma in situ (CIS). 75 patients with a urothelial bladder tumor were submitted to 165 endoscopic procedures under anesthesia including transurethral resection of any bladder tumor and random mucosal biopsies in the 4 quadrants of the bladder. The frequency and severity of mucosal anomalies rise with the tumor grade and stage: in stage 0.

[Bladder tumors. Indications for and results of routine biopsies of the macroscopically healthy mucosa (with a study of surface antigens)].

The routine biopsy of macroscopically normal mucosa has demonstrated the frequency of anomalies (hyperplasia, dysplasia or carcinoma in situ) associated with bladder tumours. 75 patients with urothelial bladder cancer were investigated by a total of 163 endoscopic examinations which, apart from resection of the tumour, included biopsies of macroscopically healthy mucosa. The frequency and severity of the lesions increased with the grade and the stage of the tumour: in cases with stage O/Ta lesions, the percentage of anomalies increased from 15% with grade 1 to 53% with grade 3.
