[Giant perirenal lipoma. Apropos of a case].

Giant perirenal lipomas are rare pathological entities. Ultrasonographic, CT scan and angiographic findings are described for a case involving a 60 year old male patient. Once the diagnosis was made, primarily thanks to CT scans, the patient was followed-up for two years, until he decided to undergo surgery. Giant perirenal lipomas are one of the focal lipomatoses that can be followed-up with CT scans since surgery is rarely required, except in cases of giant tumors as in our patient (6 kg).

[27 cases of rare forms of cancer of the corpus uteri].

Based on 27 rare forms of carcinoma of the endometrium (adenoacanthomas, clear cell adenocarcinomas, mulleroblastomas, leiomyosarcomas), the authors discuss their observations and compare their findings with literature data. The only forms with a more favorable prognosis than cancer of the endometrium is pure adenoacanthoma. Delays in diagnosis remain all too frequent. Post-surgery treatment including chemotherapy appears preferable to surgery alone for these severe lesions which result more often in local recurrences than in pulmonary metastases. New chemotherapy associations (ADR-DTIC) have given results which justify their use, while radiotherapy and curietherapy reduce the number of recurrences, except for leiomyosarcomas.

[Lymph node involvement in 50 cases of thyroid cancer. Topographic and prognostic study].

From a series of 50 thyroid cancers with lymph node metastases, the authors have conducted a topographical study of lymph node dissemination in the neck according to the topography of the primary cancer and its anatomopathological form. The prognostic aspects drawn from this casuistic study concern the anatomopathological form, the type of lymph node extension in the neck, and the type of lymph node dissection carried out for curative purposes. This study's main findings are that the anatomopathological element predominates over lymph node dissemination, and that conservative lymph node removal remains preferable to the classical total excision.

[Cutaneous apudoma. Apropos of a case and review of the literature].

It has been suggested that Merkel Ranvier cells, generally considered as belonging to the Apud system, may be the origin of extremely rare skin tumors. The authors analyse the characteristics of an apudoma in connexion with a case, and compare their findings with those of 58 other cases reported in the literature. With light microscopy techniques, the differential diagnosis is essentially one of a non-differentiated primary or secondary carcinoma, or of a lymphosarcoma. Detection by electron microscopy of neurosecretory granules in the cell cytoplasm, the neuron-specific enolase activity, when this is detectable, the possibility of ectopic polypeptide secretions, and the evolution potential of the tumor, are all features warranting inclusion of this type of tumor in the category of apudomas.

[Chemotherapy associated with surgery in advanced breast cancer (author's transl)].

Fifty patients with advanced breast cancer inoperable from the outset were treated at the Centre Antoine Lacassagne, Nice, with primary chemotherapy (3 cycles) followed by surgery (mammectomy dissection or Halsted). At the time of writing, the minimal follow-up period is 36 months. Detailed study of the various parameters initially present, clinical observations after chemotherapy and before surgery, and examination of surgical specimens have demonstrated the effectiveness of primary chemotherapy. Chemotherapy may be continued after surgery following the usual consolidation regimen and associated with local irradiation if required. The value of surgery lies in the irreplaceable information it provides on the nature and degree of local extension; it allows for optimization of complementary treatments whilst avoiding systematic procedures, such as local irradiation and, possibly, modified chemotherapy. The therapeutic solution proposed appears to be preferable to other treatments, including radiotherapy alone, chemotherapy plus radiotherapy, or surgery followed by radio -- and chemotherapy.

[An other case of Ogilvie's syndrome (author's transl)].

The authors relate a case of acute functional obstruction, appearing after treatment of a cancer of rectum with extension to prevertebral plexus. The cause of the colic trouble appears to be neurological and due to a sympathetic and parasympathetic transmission block, while intrincic plexus was normal. Inefficacy of the contractions was established by radiology and endoscopy (electrical and pharmacodynamic stimulation and measure of pressure); it predominated in the left transverse colon. Caecal perforation has been avoided up till now after two years, without modification of clinical course, the patient evacuated his colon with the help of enemas. It seems probable that this case can be classified as Ogilvie's syndrome, the bibliography of which has been looked up and criticized.

A radiologic study of chronic radiation-induced injuries of the small intestine and colon.

On the basis of 144 radiation-induced intestinal and colorectal lesions seen in 109 patients, the authors review the radiologic aspects associated with such affections. Two points are emphasized: (1) the chronic and still active nature of radiation-induced injury which can explain the appearance of lesions more than 10 years after irradiation, and (2) the locoregional nature of the affection which warrants systematic exploration of the urinary tract by intravenous pyelography in addition to radiologic and endoscopic investigation of the digestive tract. The authors also advise an echography and/or CT scan to detect any neoplastic recurrence.

Echographic aspects of thyroid and parotid localizations in non-Hodgkin lymphomas.

The authors present four observations of rare localizations of non-Hodgkin lymphomas (3 cases of lymphoma of the thyroid, 1 case of lymphoma of the parotid), all of which were studied by echography. In two of the thyroid localizations, the echographic pattern was identical to that observed for nodes in non-Hodgkin lymphomas, and thus differs from that of cysts and necrotized or cystic tumors. In the one case of secondary lymphoma of the thyroid, accompanied by diffuse enlargement of the gland but no histological proof, echography revealed only diffuse enlargement, without any anomaly in the echostructure. In the one case of lymphoma of the parotid, the echographic image was similar to that of a lymphomatous node, but it cannot be formally differentiated from the structure which can be observed for a mixed tumor or a cystic lymphangioma.

Hepatic oil embolization following lymphangiography. A report of 12 cases.

The authors report on 12 personal observations of lymphoportal fistulas, which represented 0.24% of their series of lymphographies. This rare complication of lymphography has no clinical or biological liver manifestations. Review of 71 cases in the literature confirmed that hepatic oil embolization only occurs when there are lymphatic masses, with or without associated thrombosis of the inferior vena cava.

[Echography in tumor pathology of uterus (author's transl)].

Based on the study of 234 cases of uterine tumor pathology, the authors attempt to define the role and limits of echography. In the case of uterine cancers, the major role of echography concerns postoperative surveillance, except for cancers of the corpus uteri for which it allows exact measurement of the size of the uterus and thus the optimization of radiotherapy. Fibromas are easily detected by echography, but in the case of submucosal or subserosal forms this technique can give false negative (submucosal forms) or erroneous diagnosis of an ovarian tumor (subserosal fibroma). Only the tumoral forms of endometriosis uterina can be recognized using echography, generally showing up as small transsonic images; infiltrating forms cannot be visualized. Echographic diagnosis of uterine polyps is often difficult. Echography has become the foremost complementary procedure following clinical examination. However, a negative uterine echogram in the presence of warning signs and in particular menorrhagia systematically warrants obtention of a hysterography to detect a polyp, a submocusal fibroma, endometrial lesions or an infiltrating cancer of the corpus uteri.

[Study of 39 T1-T2 cervical stump cancers treated by a radio-surgical procedure (author's transl)].

The authors present a casuistic study of 39 cervical stump cancers treated by combined radio-surgery at the Cancer Center in Nice. The protocol is similar to that of the uterine cervix. The overall five years survival rate is 68 per cent. Lymph node involvement occurred in 15 per cent of cases; non-sterilized cervical stumps represented 24 per cent. Two recurrences and two metastases were observed.
