Breast reductions: what to do with all the tissue specimens?

In order to find some guidelines for adequate examination of the often very large amount of tissue removed at reduction mammoplasties, a thorough macro- and microscopic study of a total of 400 specimens from 200 consecutive cases of bilateral breast reductions was done. The majority of patients were younger than 30 years of age. In these cases no abnormalities were found and a thorough macroscopic examination performed by an experienced pathologist is believed to be sufficient in this age group. In older women we encountered diverse findings, the most noteworthy being lobular carcinoma in situ in 8% of patients in this series who were over 40 years of age. This indicates the need for generous histological sampling in this age group. The potential value of roentgenological examination is also discussed.

Clinically unrecognised renal carcinoma: aspects of tumor morphology, lymphatic and haematogenous metastatic spread.

In a series comprising 235 clinically unrecognised renal carcinoma, metastatic spread was found in 56 cases (24%). In 82% of cases with metastases the spread involved more than one site. Lymphatic spread was diagnosed in 37 patients. Lymph node metastases were usually multiple and multifocal and were almost as common in the mediastinum as in the retroperitoneal space. In cases with involvement of these sites and/or supraclavicular nodes, concomitant metastases in the lungs were observed in 86% and in other organs in 11%. Since lymph node invasion is a strong indicator of systemic spread, the therapeutic benefit of radical lymphadenectomy seems very low, whereas a limited unilateral dissection is justified mainly for its value as a staging procedure.

Clustered breast calcifications.

In a consecutive series, clustered breast calcifications were classified according to their radiographic appearance. Rounded and 'cloudy' calcifications, and calcifications showing sedimentation were virtually always associated with benign disorders. All other types of clustered calcifications implied a substantial risk of carcinoma. Furthermore, calcifications appearing or increasing during an observation period (median 24 months) implied a larger risk than those remaining unchanged. Guidelines for the management of patients with clustered breast calcifications are given.

The contralateral breast at reconstructive surgery after breast cancer operation--a histopathological study.

The present study concerns 73 patients with known unilateral breast carcinoma. Thirty of the patients had a primary invasive carcinoma removed and at a later operation contralateral subcutaneous mastectomy with implantation of a prosthesis. This was performed with or without ipsilateral breast reconstruction. Forty-three of the cases had an in situ carcinoma found by local excision, whereafter bilateral subcutaneous mastectomy was performed in 38 cases. Five cases had already had an ipsilateral mastectomy and contralateral subcutaneous mastectomy was performed. The histological examination of the subcutaneous mastectomy specimens was extensive with breasts cut into 3-5 mm slices, which were embedded and cut in large sections and cut in large sections allowing us to map all lesions. 42.5 per cent of the contralateral breasts contained invasive or in situ carcinoma. In about 70 per cent of the cases other histological lesions, considered more or less precancerous, were found in the contralateral breast. Our results speak in favor of an active approach to the contralateral breast at reconstruction, especially in cases with a long life expectancy after the first carcinoma. It is psychologically comforting to the patient to know that most of the breast gland, which could be the future origin of a new carcinoma, has been removed.

Breast carcinoma. Progression of tubular carcinoma and a new classification.

On histologic and statistic basis a new classification of ductal breast carcinoma is proposed. One group consists of five types, representing different stages in a continuous progression from tubular carcinoma to pure "ductal" type. Another group is comprised by invasive "comedo" carcinoma which is derived from intraductal carcinoma. The development of tubular carcinoma from sclerosing lesions is stressed.

Breast hamartomas. An important entity in mammary pathology.

1. Fifteen cases of a rather distinct entity of tumour-like lesion in the breast are presented. 2. They have a distinct mammographic appearance and can be easily shelled out at surgery, leaving symmetrical breasts. 3. They are well-circumscribed lumps of varying size with a smooth surface. 4. Microscopically they show normal or dysplastic glandular structures of lobules and ducts, without neoplastic features, within a prominent fibrous stroma. The lesions appear to be closely related to adenolipomas.

Extreme duct papillomatosis of the juvenile breast.

Three cases of peculiar and very severe ductal papillomatosis of the breast are reported. This ductal papillomatosis was unusual, both in its histological architecture and in occurring in juveniles, viz. girls aged 11, 14, and 17 years. In two of the patients breast cancer was diagnosed 27 and 11 years later. In one of them the ductal papillomatosis must be presumed to have been precancerosis, while in the other patient there was possibly from the outset an unusually papilliferous, intraductal carcinoma of low malignancy.

Breast cancer screening with mammography: a population-based, randomized trial with mammography as the only screening mode.

A population-based, randomized breast cancer screening project was undertaken using mammography alone. Of 17,447 invited women aged 50-69, 12,765 (73%) attended the screening. On the basis of the screening films, malignancy was suspected in 405 women (3.2%) who were recalled for complete mammography. Additional films showed that the suspicion of malignancy was false in 194 women. The remaining 211 women (1.7%) were referred for clinical and cytological examination. Of these, 159 had surgery. Breast cancer was proved in 97 women, corresponding to a prevalence rate of 7.6/1000. Fifty-three (55%) of the carcinomas were either in situ or invasive with a diameter of less than or equal to 1 cm. Axillary metastases were found in 19 patients (19.6%). Cancers detected at screening were significantly less advanced than those in the control group. There was a remarkably high frequency of tubular carcinoma among cancers detected at screening.

Lesions of the dorsal renal artery in surgery for renal pelvic calculus. A potential cause of renovascular hypertension.

2 cases of lesions of the dorsal renal artery in surgery for renal pelvic calculus are described. In 1 of the cases hypertension developed. Anatomic factors and previous operations predispose to this complication. An arterial complication should be suspected when hypertension develops postoperatively. The blood pressure of patients with known renal vascular complications should be checked repeatedly for several months postoperatively. The diagnosis is radiological, renal angiography being the definite procedure although a reduction of kidney size observed at urography may indicate the vascular lesion.

Mammary hamartomas.

Five cases of mammary hamartoma are described, with special reference to the radiographic features. Hamartomas are well circumscribed lesions composed of normal or dysplastic mammary tissue. They are probably more common than has been anticipated from the literature and are important because they may be confused with other well circumscribed tumors, such as cystosarcoma phyllodes. The radiographic characteristics of hamartoma allows a tentative diagnosis in most cases.

Correlations between clinical and postmortem findings in listeriosis.

Clinical data were correlated with postmortem findings in 14 cases of fatal listeriosis in adults and 23 cases of listeriosis during pregnancy and the neonatal period. Most children born with congenital listeriosis showed the typical morphological picture of granulomatosis infantiseptica. Occasionally no pathological changes were demonstrable. In adult patients the morphological lesions were those of non-specific purulent meningoencephalitis or septicemia. Sometimes encephalitis with abscesses in the brain was found.
