Papillomas of the breast 15 mm or smaller: 4-year experience in a community-based dedicated breast imaging clinic.

PURPOSE: To determine the significance of small, often mammographically occult and asymptomatic papillomas of the breast 15 mm and smaller. METHODS: Four-year retrospective review of papillomas of the breast in a community-based dedicated breast imaging center, with a selected cohort of 179 papillomas 15 mm or smaller in 147 patients, all completing image-guided core biopsy followed by surgical excision. RESULTS: Of 179 papillomas 15 mm or smaller, 36 % were abnormal (24 % atypia; 12 % cancer). Twenty-one percent had a surgical upgrade diagnosis. One hundred forty-six benign papillomas by core biopsy yielded 7 (4.7 %) cancers and 25 (17 %) atypias (atypical ductal hyperplasia (ADH), atypical lobular hyperplasia (ALH), or lobular carcinoma-in situ) at surgical excision. Seven of 34 (14 %) of very small papillomas (5 mm or smaller) showed cancer. Twelve of 72 (11 %) and 8 of 36 (13 %) papillomas showed cancer in normal-risk and high-risk patients, respectively. Increasing age (70+ years) associated strongly with increasing risk of papillomas with cancer (10 of 35, 29 %). Thirteen unsuspected papillomas in 10 patients with new nonpapillary breast cancers yielded 3 atypias and 3 additional cancers, changing surgical management in half of these patients. Breast ultrasound identified 44 % of papillomas as incidental findings, all mammographically occult and asymptomatic. CONCLUSIONS: There is no size threshold below which a papilloma of the breast can be safely watched or ignored without risking a missed diagnosis of atypia or cancer. Identification of papillomas in patients with new nonpapillary breast cancers can change patient management in up to half of these patients. Finally, breast ultrasound significantly enhances identification of unsuspected papillomas.

Peritoneal washing cytologic analysis of ovarian serous tumors of low malignant potential to detect peritoneal implants and predict clinical outcome.

BACKGROUND: Patients with ovarian serous tumors of low malignant potential (OSLMP) who have peritoneal implants, especially invasive implants, are at an increased risk of developing tumor recurrence. To the best of the authors' knowledge, the ability of peritoneal washing (PW) cytology to detect the presence and type of peritoneal implants has not been adequately investigated, and its prognostic significance is unknown. METHODS: Records and PW specimens of 101 patients diagnosed with and treated for OSLMP between 1996 and 2010 at The University of Texas MD Anderson Cancer Center were retrospectively reviewed. Patients' staging biopsy findings were compared with the results of the authors' review of the PWs. Follow-up data were also analyzed. RESULTS: Of the 96 patients for whom staging biopsy results were available, 26 (27%) had peritoneal implants (17 noninvasive and 9 invasive), 19 (20%) had endosalpingiosis, and 51 (53%) had negative findings. The PW specimens of 18 of the 26 patients (69%) with peritoneal implants were positive for serous neoplasm, and a correlation was found between cytologic and histologic findings (P < .0001). The sensitivity, specificity, positive predictive value, and negative predictive value were 69%, 84%, 62%, and 88%, respectively. Four of 101 patients had disease recurrence; 3 of these patients had invasive implants and 1 patient had noninvasive implants. None of the patients who had negative staging biopsy findings or endosalpingiosis but did have PW specimens that were positive for serous neoplasm developed disease recurrence. CONCLUSIONS: PW cytology detects the presence of peritoneal implants with moderate accuracy. However, long-term studies are needed to determine whether positive PW cytologic findings are an independent predictor of tumor recurrence.

Vascular compromise as a cause of sudden death in a pediatric patient with widely metastatic testicular germ cell tumor.

During hospitalization for evaluation of a large testicular tumor with extensive metastatic disease, this 14-year-old boy collapsed while showering and could not be resuscitated. At autopsy, there was no evidence of thromboembolic phenomenon, a known cause of sudden death in metastatic testicular tumors and other large abdominal tumors. However, marked compression of the inferior vena cava by a large pelvicoabdominal tumor mass and findings suggestive of systemic-portal shunting were consistent with the death due to the impaired venous return via the inferior vena cava.

Functional outcome after treatment of lower-extremity nonunions.

BACKGROUND: The results for nonunion surgery usually have been judged in terms of bony union, time to union, infection rate, range of motion for the adjacent joints, and muscle strength. The goal of this study was to assess the improvement of patient-oriented physical and mental functional outcomes. METHODS: The functional status of 23 patients with nonunion of the lower extremity was assessed using the Short-Form Health Survey (SF-36) questionnaire. The SF-36 subscores were compared with preoperative values and with the average values for the U.S. population. RESULTS: Of the 23 patients, 21 healed. The functional status for nonunions of the lower extremity was greatly improved 1 year after operative intervention in this study. Nevertheless, the results show that it did not reach the level of the average U.S. population. CONCLUSION: The results of this study can be used to guide patients' expectations regarding the functional outcome of treatment for a nonunion of the lower extremity.
