Introduction: Multinucleated giant cells (MGC) are a rare finding when evaluating axillary sentinel lymph nodes. Some are described as foreign body-type MGC accompanied by foamy macrophages. They have been rarely reported in nodes from patients in which a previous breast biopsy was performed. The tissue damage induced by biopsy results in secondary changes including fat necrosis and hemorrhage that can migrate to axillary nodes. In this report, we illustrate a lipogranulomatous reaction in cytologic samples obtained during a sentinel lymph node examination of a woman previously biopsied because of breast carcinoma. We have found no previous cytologic descriptions and consider it an interesting finding that should be known to avoid diagnostic misinterpretations. Case: A 51-year-old woman underwent mastectomy of the right breast with a sentinel lymph node biopsy at our medical center. One month before, a control mammography revealed suspicious microcalcifications and a vacuum-assisted breast biopsy resulted in a diagnosis of high-grade intraductal carcinoma with comedonecrosis. Surgery with a sentinel lymph node biopsy was performed. The sentinel node was processed as an intraoperative consultation. Frozen sections and air-dried Diff-Quik stained samples were obtained. They showed abundant lymphocytes with MGC and tumoral cells. MGC showed ample cytoplasm with evident vacuoles of variable size. Occasional hemosiderin-laden macrophages were also present. The complete histologic analysis and immunohistochemical studies revealed no malignant cells. Histologic analysis showed, in subcapsular location, occasional MGC phagocyting lipid droplets. Hemosiderin-laden macrophages were a common finding. Conclusion: Lipogranulomas may appear at axillary sentinel lymph nodes because of fat necrosis induced by previous breast biopsy. The most important consideration is not confounding MGC with epithelial cell clusters. This can occur with not well-processed samples, especially if unmounted.

Aims and Background Lymphatic mapping and sentinel lymph node biopsy provide important prognostic data in patients with early stage melanoma and are crucial in guiding the management of the tumor. We report our experience with lymphatic mapping and sentinel lymph node biopsy in a group of patients with primary cutaneous melanoma and discuss recent concepts and controversies on its use. Patients and Methods A total of 111 patients with stage I-II AJCC primary cutaneous melanoma underwent lymphatic mapping and sentinel lymph node biopsy from December 1999 through December 2004 using a standardized technique of preoperative lymphoscintigraphy and biopsy guided by blue dye injection in addition to a hand-held gamma probe. After removal, sentinel lymph nodes were submitted to serial sectioning and permanent preparations for histological and immunohistochemical examination. Complete lymph node dissection was performed only in patients with tumor-positive sentinel lymph nodes. Results Sentinel lymph nodes were identified and removed in all patients (detection rate of 100%), and metastases were found in 17 cases (15.3%). The incidence of metastasis in sentinel lymph nodes was 2.1%, 15.9%, 35.2%, and 41.6% for melanomas < or 1.0, 1.01-2.0, 2.01-4.0, and > 4.0 mm in thickness, respectively. Complete lymph node dissection was performed in 15 of 17 patients with positive sentinel lymph nodes, and metastases in non-sentinel lymph nodes were detected in only 2 cases (11.7%). Recurrences were more frequently observed in patients with a positive than in those with negative sentinel lymph node (41.1% vs 5.3% at a median follow-up of 31.5 months, P<0.001). The false-negative rate was 2.1%. Conclusions Our study confirms that lymphatic mapping and sentinel lymph node biopsy allow accurate staging and yield relevant prognostic information in patients with early stage melanoma.

e11605 Background: Sentinel lymph node biopsy is widely accepted method to determine nodal stage of breast cancer. There are several reported method for detecting sentinel lymph node. The aim of this study was to show the new detection method of sentinel lymph node and show the effectiveness of this method. Methods: We did prospective study and enrolled 25 patients who underwent partial mastectomy and sentinel lymph node biopsy. We injected indigocyanine green (green dye) at peritumoral lesion, indigocarmine dye (blue dye) in subareolar area and radioisotope (Tc-99m) injection. Sentinel lymph nodes are identified by color change or radioisotope uptake, and classified by each color (blue or green) and radioisotope uptake. We compared the detection rate from our study with that from the previous studies. Results: Sentinel lymph nodes were detected in all patients (25/25). Green color stained sentinel lymph nodes were identified in 18 patients (18/25), blue color stained sentinel lymph nodes were identified in 15 patients (15/25) and radioactive lymph nodes were identified in 19 patients (19/25). Conclusions: The triple mapping method showed higher detection rate than the previous studies and this method is recommendable to detect sentinel lymph node. No significant financial relationships to disclose.

PURPOSE: To assess the importance of sentinel lymph node biopsy in patients with cutaneous melanoma. METHODS: Ninety consecutive non-randomized patients with stages I and II melanoma who underwent sentinel lymph node biopsy were followed up prospectively for six years. RESULTS: Patients were followed up for a mean period of 30 months. Their mean age was 53.3 years, ranging from 12 to 83 years. Thirty patients were male (37.5%) and 50, female (62.5%). Sentinel lymph node was positive in 32.5% and negative in 67.5%. It was found that the thicker the tumor, the greater the incidence of positive sentinel lymph nodes. In the group of patients with positive sentinel lymph nodes, recurrence occurred in 43.5%, but in those with negative sentinel lymph nodes, in only 7%, what points out to the association of tumor recurrence and positive sentinel lymph nodes. There were no major postoperative complications. CONCLUSION: Sentinel lymph node biopsy was demonstrated to be a safe method for selecting patients who need therapeutic lymphadenectomy.
