[Computed tomography-guided transthoracic biopsy after negative fiber-optic endoscopy; apropos of 134 patients].

PURPOSE: To evaluate the diagnostic accuracy of transthoracic needle biopsy (TNB) in patients being treated for cancer in order to compare results from small and large pulmonary nodules and to study the efficiency of pathology versus cytology analysis. PATIENTS AND METHODS: 141 consecutive CT-guided TNBs were performed in 134 patients. Cancer had been diagnosed in all cases. From the CT images, nodules were classified as small (< or = 15 mm) (n = 63; 47%) or large (> 15 mm) (n = 71; 53%). RESULTS: There were 16 benign and 118 malignant lesions (92 metastasis, 18 primary, 8 unspecified). There was no statistically significant difference for sensitivity and for prevalence of pneumothorax between small or large nodules. For the 107 true-positive and 16 true-negative results, the cytology examination was positive alone in 41 cases (33.3%), the pathology examination in 24 cases (19.5%) and both in 58 cases (47.2%). CONCLUSION: The diagnostic efficiency of CT-guided transthoracic needle biopsy is as good for small pulmonary nodules (> or = 15 mm) as for larger lesions. This technique is particularly useful in the diagnosis of secondary lesions and does not increase the risk of complications, even in case of small nodules. Ordering both pathology and cytology examinations improves the efficacy of TNB.

Epithelioid sarcoma of the tongue.

A case of epithelioid sarcoma in the tongue is reported. The patient, a 35 year old woman, presented with a non-ulcerated painful lesion of the tongue. Microscopically, the tumour was characterised by multiple coalescent nodules with central geographic necrosis infiltrating the lingual muscle. The tumour cells were epithelioid with abundant eosinophilic cytoplasm and atypical nuclei. Immunohistochemically, the tumour cells stained for vimentin, keratin, and epithelial membrane antigen. These morphological and immunohistochemical appearances led to the diagnosis of epithelioid sarcoma of the tongue. Seven years later, the patient died with metastatic dissemination to the scalp, lungs, and brain. No case of epithelioid sarcoma arising in the tongue has been described previously.

[Pseudomyxoma peritonei secondary to a teratoma of the omentum with a mucinous component of borderline malignancy].

A mature cystic teratoma of the omentum occurred in a 37 years old woman who had an appendicectomy at the age of 8. This extragonadal teratoma contained a predominant mucinous glandular pattern of borderline malignancy, responsible for pseudomyxoma peritonei. Ovarian biopsies had only shown surface mucinous deposits at the time of the first laparotomy but two years later ovarian mucinous cystadenomas of borderline malignancy appeared. The patient developed intestinal obstruction, surround by mucinous retractile material and died four years and an half after initial diagnosis. This case is, to our knowledge, the first pseudomyxoma peritonei occurring from an extragonadal teratoma, the events chronology suggesting the secondary nature of the ovarian tumors.

[Phyllodes tumors].

A review of mammary phyllodes tumors is presented. Clinical, radiological and cytological features are treated, with special emphasis on the histopathological grading system and prognostic indicators. Other analytical methods are described: immunohistochemistry, hormonal receptors study, flow cytometry and electron microscopy. A large place is also given to differential diagnosis, clinical course, histogenesis and originality of some phyllodes tumors. The authors stress the importance of wide excision and the contribution of frozen sections in surgical treatment.

[Lymphatic metastasis revealing a calcitonin-secreting extrathyroid carcinoma].

We report a case of right sus-clavicular lymph nodes metastasis which revealed a calcitonin secreting carcinoma in a 36 years old woman. Any tumor has been noted in the completely included thyroid gland. There was many lymph nodes metastasis in the right mediastinal removal. A pulmonary origin neuroendocrine carcinoma hyposthesis has been evoked. The outcome proved to be quickly fatal with cerebral metastasis occurrence. Extrathyroid calcitonin secreting carcinomas are rare. Then the discussion was founded on the diagnosis process in the face of hypercalcitoninemia, and on the calcitonin secretion by neuroendocrine cells and neoplasms of the lung.

[Immunohistochemical demonstration of ceruloplasmin and lactoferrin in a series of 59 thyroid tumors].

Fifty-nine thyroid tumors were re-examined and studied using immunohistochemistry to detect the presence of ceruloplasmin (CP), lactoferrin (LF), thyroglobulin, thyrocalcitonin, carcinoembryonic antigen and ferritin. In an attempt to study the contribution of the immunodetection of CP and LF in the diagnosis of malignant versus benign tumors, specially in follicular tumors, we compared our results of immunodetection with those of Tuccari and Barresi, and carried out our own studies on the usefulness of these immunolabelling. Concerning CP and LF staining, we have found the following data: 1) little (in contrast to Tuccari and Barresi) or no staining in normal thyroid and benign adenomas; 2) diffuse and intense staining in papillary and follicular carcinomas (as noted by the previous authors); 3) diffuse and weak staining for medullary carcinomas (in contrast to Tuccari and Barresi who found none). Our findings suggest that a diffuse and intense cytoplasmic staining with CP and LF concerning more than one third of all cells is a criterion of malignancy, whereas a weak paranuclear staining of a few cells is more in favor of a benign process.

[Stromal luteoma of the ovary. Differential diagnosis of steroid cell tumors].

An observation of a stromal luteoma of the ovary is reported. It is a rare tumor (only about thirty cases of it have been published yet), occurring mostly in post menopausal women. Endocrine symptoms and sometimes virilizing signs may be observed. Abnormal vaginal bleeding is the most frequent clinical manifestation. This macroscopically observed tumor is surrounded by ovarian stroma and entirely composed of luteinized cells devoid of crystals of Reinke. Hyperthecosis of ovarian stroma is often observed. Its evolution is always benign. The authors recalled the place of stromal luteoma of the ovary among steroid (lipid) cell tumors and the elements of a differential diagnosis. These tumor might derive from ovarian stromal cells.

[Primary lymphomas of the breast. 9 case reports].

Between the 1st of January 1974 and the 30th of June 1989, we saw 9 cases of primary lymphoma of the breast at the Oscar Lambret Centre, all occurring in women. This comprised 0.27% of the malignant tumours of the breast and 3.2% of all non-Hodgkin lymphomas. 8 occurred on the right side and 1 on the left. There were multiple tumours in 5 cases. The clinical findings were always suggestive of a malignant condition and so were the mammography findings in 6 cases. Two patients had total mastectomy. In the other cases, the diagnosis was made (twice) by biopsy or by lumpectomy (5 cases). Using Kiel-Lennert's classification: 5 were highly malignant and 4 of low grade malignancy (using the Working Formulation, three were moderate and 4 were intermediate; 1 was very high grade and 1 intermediate or high). Treatment changed a lot during the period under consideration. Five patients are still alive without any recurrence. One died of lymphoma and two died of intercurrent causes and one died of unknown causes.
