1/19. Infusion port dislodgement of bilateral breast tissue expanders after MRI.Tissue expanders are placed routinely for breast reconstruction, and magnetic resonance imaging (MRI) is a common diagnostic procedure. Many studies have reported on the safety of MRI in patients with nonferromagnetic implants; however, many tissue expanders contain ferromagnetic components. The authors present a case of bilateral tissue expander infusion port dislodgment after MRI. A 56-year-old woman underwent bilateral mastectomy and immediate reconstruction with McGhan BIOSPAN tissue expanders. These implants contain integral nonferromagnetic infusion ports, as well as small, powerful Magna-Site magnets. Several weeks postoperatively the patient underwent MRI of her spine, which was ordered by her primary physician for back pain. Subsequently, the infusion ports could not be located with the finder magnet. A chest radiograph was obtained, which demonstrated bilateral dislodgment of the infusion ports. Surgical removal and replacement of the tissue expanders were required. safety considerations of MRI have been discussed extensively in the literature, and data on MRI with various implanted devices have been obtained. The potential risks of performing MRI on patients with metallic implants include conduction of electrical currents, heating of the implant, misinterpretation resulting from artifact, and the possibility of movement or dislodgment of the implant. The small magnet integral to many tissue expanders may be overlooked by patients and physicians during pre-MRI screening. All patients undergoing tissue expansion with implants that contain integral ports should be thoroughly warned about the potential hazards of MRI.- - - - - - - - - - ranking = 1keywords = back, chest (Clic here for more details about this article) |
2/19. Intravascular lymphomatosis presenting within angiolipomas.This report presents a case of intravascular lymphomatosis identified within an angiolipoma. The patient was a 73-year-old woman with a history of lobular carcinoma of the breast who presented with a chest wall nodule near the site of prior mastectomy. Microscopically, the nodule was composed of encapsulated adipose tissue with an associated vascular proliferation. Many of the vascular lumina were expanded by collections of large pleomorphic cells with vesicular nuclei and prominent nucleoli. These atypical cells displayed immunoreactivity for CD45RB (leukocyte common antigen) and the pan-B cell marker CD20 (L26). The patient subsequently developed multiple lesions of the extremities and died soon after developing symptoms referable to the central nervous system. Intravascular lymphomatosis most commonly presents with central nervous system and dermatologic involvement although any organ system may be affected. Intravascular lymphomatosis is an aggressive neoplasm that is generally diagnosed at postmortem examination. This case shows the protean manifestations of intravascular lymphomatosis and highlights the necessity of considering this malignancy in the differential diagnosis when entertaining the diagnosis of vascular invasion by carcinoma.

3/19. Fine needle aspiration cytology of sclerosing lobular hyperplasia of the breast: a case report.BACKGROUND: Sclerosing lobular hyperplasia presenting as a palpable, circumscribed nodular mass in a young female's breast is characterized histologically by prominent hyperplasia of the lobules and sclerosis of the intralobular connective tissue. The cytomorphologic features and differential diagnosis of the lesion are presented. CASE: A 14-year-old female presented with a painless, progressively increasing, nodular, firm, mobile lump measuring 5 x 5 cm in the right breast. The clinical and radiologic diagnosis was fibroadenoma. Fine needle aspiration smears showed a clean background with uniform, round to oval epithelial cells in flat sheets, round clusters and rosettelike (acinar) arrangements. A few naked nuclei were present, while stromal fragments were not seen. CONCLUSION: When analyzed in the context of the clinical findings, the cytologic features of sclerosing lobular hyperplasia help to differentiate it from other benign palpable nodular lesions of the juvenile breast.- - - - - - - - - - ranking = 0.54134917860888keywords = back (Clic here for more details about this article) |
4/19. Pectus excavatum complicating breast cancer surgery.breast cancer surgery in the presence of previous reconstruction for pectus excavatum has not been reported. Such a case is described where simultaneous chest wall resection was undertaken because of fibrous tissue distortion mimicking malignant infiltration. Furthermore, postoperative adhesions necessitated opening the pleural lining during rib resection. This resulted in recurrent pleural effusion from axillary lymphatic leakage that required thoracocentesis. breast surgery in these circumstances has to be performed with care.- - - - - - - - - - ranking = 0.45865082139112keywords = chest (Clic here for more details about this article) |
5/19. Metastatic breast cancer to 4 eyelids: a clinicopathologic report.A 47-year-old woman presented complaining of progressive, painless swelling of all 4 eyelids for 6 weeks. Her medical history was significant for breast cancer 14 months prior. Examination results showed a diffuse, firm thickening of all 4 eyelids with mild erythema of the overlying skin. Orbital computer tomography revealed extensive preseptal infiltration of soft tissue of all 4 eyelids, which enhanced with contrast. Results of a bilateral biopsy of the upper eyelids demonstrated extensive infiltration of the orbicularis muscle. Histologic features were consistent with metastatic breast cancer. Results of both the primary breast cancer biopsy taken 14 months previously and the eyelid biopsies were the same histologic type. Presentation of metastatic breast cancer to the eyelids is rare, but a recurrence must be considered in any patient with a history of breast cancer, despite the length of tumor-free survival. Bilateral involvement should not exclude metastases from diagnostic consideration, but rather, the diagnosis requires a high degree of clinical suspicion and recognition of the various cutaneous forms.- - - - - - - - - - ranking = 0.22184162491747keywords = upper (Clic here for more details about this article) |
6/19. duodenal obstruction from isolated breast cancer metastasis: a case report.Metastatic involvement of the upper gastrointestinal tract from breast cancer has been reported in autopsy series as occurring in more than 15% of patients, usually associated with extensive systemic spread; clinical manifestations from such metastases have been described in less than 1% of cases. Lobular infiltrating carcinoma seems to have a different metastatic pattern than the ductal type, with an apparent predilection for the gastrointestinal tract. Metastatic presentation as an isolated intestinal obstruction without other signs of metastatic spread is extremely rare. We present a case of isolated duodenal metastasis from breast cancer, associated with intestinal obstruction, as the first sign of metastatic spread.- - - - - - - - - - ranking = 0.22184162491747keywords = upper (Clic here for more details about this article) |
7/19. Metastatic breast carcinoma to bone disguised by osteopoikilosis.A case of metastatic lobular carcinoma of the breast in conjunction with osteopoikilosis is described. Widespread diffuse sclerotic bone lesions were identified on radiographs in a patient with breast carcinoma. In addition computed tomography demonstrated discrete spherical areas of increased density throughout the skeleton manifest typically by osteopoikilosis. No systemic symptoms were evident, blood parameters were normal and the lesions did not demonstrate any increased uptake of technetium on bone scan. An iliac crest bone biopsy, however, revealed metastatic disease in addition to osteopoikilosis. Conventional radiological investigations may not delineate metastasis on a background of bone dysplasia.- - - - - - - - - - ranking = 0.54134917860888keywords = back (Clic here for more details about this article) |
8/19. Clinicopathologic analysis of breast lesions associated with multiple papillomas.We performed a retrospective clinicopathologic study of 28 patients with breast lesions characterized by the presence of multiple (at least 5) papillomas (MPs) in at least 2 nonconsecutive blocks. All histologic sections were assessed for the presence of coexisting fibrocystic lesions, including atypical hyperplasia (atypical ductal hyperplasia [ADH] or atypical lobular hyperplasia [ALH]), lobular carcinoma in situ (LCIS), and papillary atypia (defined as nuclear hyperchromatism, stratification, and architectural complexity of a lesser degree than in papillary carcinoma). All of the lesions were compared with a set of cases in which ductal carcinoma in situ (DCIS) (n = 20) or invasive carcinoma (INV)(n = 13) was accompanied by MPs. The MP cases had a characteristic morphologic appearance, typically presenting as a mass comprising multiple adjacent ducts filled by papillomas, accompanied by dense fibrosis and intermingled with various proliferative fibrocystic lesions, particularly florid adenosis. Atypical hyperplasia was a frequent finding (in 12 of 28 cases; 43%), particularly in cases with atypical papillomas (7 of 11; 63.6%). Although contralateral lesions occurred in 4 of 28 patients (14.2%; 3 MPs and 1 INV), only 1 patient (4%) has developed ipsilateral breast carcinoma (mean follow-up, 47 months). DCIS associated with MP was typically low grade (17 of 20; 85%) and arose from areas within or immediately adjacent to preexisting benign lesions. None has recurred (mean follow-up, 41 months), although 1 patient has contralateral MP and 3 patients (23%) have developed carcinomas in the opposite breast. INVs developing in a background of (ipsilateral) MPs were mostly small (8 of 11 <2.0 cm), node negative (7 of 10), and estrogen receptor (ER) positive (8 of 8). Only 1 of 13 patients (8%) has died from disease (mean follow-up, 59 months), but 5 (38%) have developed contralateral breast lesions (including 1 MP, 1 MP-DCIS, 1 DCIS, 1 LCIS, and 1 INV). We conclude that the frequent associations with ADH, ALH/LCIS, malignant lesions, and bilaterality imply that MP may represent a marker of constitutionally increased breast cancer risk. Because carcinomas arose within or close to areas involved by preexisting benign MP lesions, it may also be appropriate to excise segments of tissue involved by MP, particularly cases with atypia, and closely monitor for contralateral disease.- - - - - - - - - - ranking = 0.54134917860888keywords = back (Clic here for more details about this article) |
9/19. Cytology of pleomorphic lobular carcinoma with apocrine cell differentiation of the breast. A case report.BACKGROUND: Pleomorphic lobular carcinoma (PLC) with apocrine differentiation is a rare breast carcinoma, and its cytologic findings have not been reported before. CASE: A 75-year-old woman had a mass in and skin rash on the left breast. Apocrine carcinoma was suggested on aspiration cytology of the mass. The cytologic smears showed a small number of rounded to oval, atypical cells that were poorly cohesive and individually scattered. The cytoplasm was relatively abundant and contained coarse granules and dropletlike, orange granules (Lendrum's granules). The cell border was distinct. Some atypical cells had intracytoplasmic lumina. The nucleoli were round and prominent, and nuclear chromatin was finely granular. The background was clean. Histologically, the tumor cells proliferated mainly in an Indian file pattern and showed a concentric, targetoid pattern around the non-neoplastic ducts. The cytoplasm was abundant, eosinophilic, granular, positive for the periodic acid-schiff reaction and diastase resistant. Immunohistochemically the tumor cells were positive for gross cystic disease fluid protein-15 (GCDFP-15) and negative for E-cadherin. Lendrum's granules showed positive expression of GCDFP-15 and lysozyme. CONCLUSION: PLC with apocrine differentiation and apocrine carcinoma may be cytologically confused. Poor cellularity, less cohesiveness, finely granular chromatin, a nonpolyhedral cellular outline and clean background indicate the former rather than the latter. It is important to be aware that PLC presents a variety of cytologic configurations.- - - - - - - - - - ranking = 1.0826983572178keywords = back (Clic here for more details about this article) |
10/19. Biphenotypic acute leukemia following intensive adjuvant chemotherapy for breast cancer: case report and review of the literature.The risk of secondary leukemia in breast cancer patients who receive adjuvant chemotherapy is an open question. We describe the case a 38-year-old woman who developed acute leukemia 18 months after completion of intense adjuvant chemotherapy with prophylactic granulocyte colony-stimulating factor (G-CSF) support and chest wall irradiation. The diagnosis of biphenotypic T-cell acute myeloid leukemia (AML) was based on morphologic and immunophenotypic criteria. Chromosomal analysis of blasts revealed multiple trisomies and tetrasomies. The patient failed to respond to induction and salvage chemotherapy and died 4 months later. This case of acute leukemia occurred in a cohort of 65 high-risk breast cancer patients who were given intense adjuvant chemotherapy during the last 5 years in our hospital. This is the first case reported in the literature of acute leukemia following intense adjuvant chemotherapy with continuous prophylactic G-CSF, which is an actively investigated therapeutic strategy. Vigilance and investigation are needed to determine the leukemogenic potential of intense adjuvant chemotherapy plus radiotherapy in breast cancer patients. A brief review of the literature that deals with acute leukemia that develops after adjuvant chemotherapy for breast cancer and with secondary biphenotypic acute leukemia is presented.- - - - - - - - - - ranking = 0.45865082139112keywords = chest (Clic here for more details about this article) |
