1/100. Diagnosing invasive cystic hypersecretory duct carcinoma of the breast with fine needle aspiration cytology. A case report.BACKGROUND: Cystic hypersecretory duct carcinoma (CHC) of the breast, first described in 1984, is a rare variant of duct carcinoma. Histologically it is characterized by the formation of dilated ducts and cysts containing an eosinophilic secretory product resembling thyroid colloid. The lining epithelium of the cysts atypically proliferates to form intraductal carcinoma. Only four cases of invasive cystic hypersecretory carcinoma have been reported. CASE: We present a case of invasive CHC with tumor emboli in many lymphatic spaces and axillary nodal metastases. The lesion was also evaluated by fine needle aspiration. Direct smears with Papanicolaou stain were highly cellular and had abundant, intensely staining, orange-to-gray-green thyroid colloid-like material. epithelial cells, showing a variety of cellular patterns, were indistinguishable from usual ductal carcinoma cells. These cytologic findings may be characteristic enough to suggest cystic hypersecretory carcinoma. CONCLUSION: The cytologic features of CHC are distinctive and correlate with histology. This was the first presentation of colloidlike secretory material in cytologic material with Papanicolaou stain in such a case. Invasive CHC tends to have aggressive behavior. Cystic hypersecretory hyperplasia coexisted in this case.- - - - - - - - - - ranking = 1keywords = lymphatic (Clic here for more details about this article) |
2/100. Myxoid variant of follicular dendritic cell sarcoma arising in the breast.Follicular dendritic cell sarcoma is a malignant tumor of the follicular dendritic cell which can arise in extranodal sites. We present here a case arising as a mass in the breast of a 41-year-old woman. The tumor was composed of mildly pleomorphic spindly cells with pale ovoid nuclei and cell processes intimately admixed with mature lymphocytes. In much of the lesion the cells were dispersed in cords in a myxoid stroma, and elsewhere there were solid sheets. The neoplastic cells were immunoreactive for CD21, CD35, EMA, and S100 protein, but not for other lymphoid markers or cytokeratin. Electron microscopy showed interdigitating cytoplasmic processes with junctions but no external lamina. The differential diagnosis includes carcinoma, lymphomas, and a variety of myxoid sarcomas. The tumor recurred within a few months and displayed increased nuclear pleomorphism and lymphatic invasion but the patient appears free of disease 3 years after the further excision. This case extends the spectrum of follicular dendritic cell sarcoma in soft tissue sites.- - - - - - - - - - ranking = 1keywords = lymphatic (Clic here for more details about this article) |

4/100. Benign lymphangiomatous papules of the skin following radiotherapy: a report of five new cases and review of the literature.AIMS: The aim of this report is to summarize the clinicopathological findings of five cases of a pseudosarcomatous vascular proliferation of the skin at the site of radiotherapy following surgery for carcinoma of the breast and carcinoma of the endometrium. To our knowledge, only five cases of this presumably rare pseudomalignant proliferation have been reported previously. methods AND RESULTS: All patients were females ranging in age from 44 to 70 years. The lesions appeared as solitary or multiple papules or vesicles localized to the field of radiation. Microscopically, they were composed of vascular spaces that exhibited atypical features without qualifying for a diagnosis of angiosarcoma. CONCLUSIONS: Our cases provide additional evidence supporting the benign nature of this atypical vascular proliferation, not recurring, never developing metastases and being cured readily by local excision. Clinical, histopathological and ultrastructural findings suggest a lymphatic origin. Whether these lesions represent a neoplastic or a reactive condition secondary to radiotherapy is unclear. The name 'benign lymphangiomatous papules of the skin following radiotherapy' is proposed.- - - - - - - - - - ranking = 1keywords = lymphatic (Clic here for more details about this article) |
5/100. yellow nail syndrome: resolution of yellow nails after successful treatment of breast cancer.yellow nail syndrome (YNS) is a rare entity of unknown cause in which congenitally hypoplastic lymphatics play a major role in the clinical manifestations of the disease. YNS has been associated with many malignancies and immune disorders. We report a case of new-onset YNS associated with breast cancer and dramatic improvement in the yellow nails with cancer treatment.- - - - - - - - - - ranking = 1keywords = lymphatic (Clic here for more details about this article) |
6/100. Supermicrosurgical lymphaticovenular anastomosis for the treatment of lymphedema in the upper extremities.Over the last eight years, the authors analyzed obstructive lymphedema of a unilateral upper extremity in a total of 27 females, comparing the use of supramicrosurgical lymphaticovenule anastomoses and/or conservative treatment. The most common cause of edema was mastectomy, with or without subsequent radiation therapy for breast cancer. As an objective assessment of the extent of edema, the circumferences of the affected and opposite normal forearms were measured at 10 cm below the olecranon of the arm. Twelve of these patients received continual bandaging. In these patients, the average excess circumference of the affected arm was 6.4 cm over that of the normal forearm; the average duration of edema before treatment was 3.5 years; the average period for conservative treatment was 10.6 months; and the average decrease in circumference was 0.8 cm (11.7 percent of the preoperative excess). Twelve patients underwent surgery and postoperative continual bandaging. In these patients, the average excess circumference was 8.9 cm; the average duration of edema before surgery was 8.2 years; the average follow-up after surgery was 2.2 years; and the average decrease in circumference was 4.1 cm (47.3 percent of the preoperative excess). These results indicated that supermicrolymphaticovenular anastomoses with postoperative bandaging have a valuable place in the treatment of obstructive lymphedema.- - - - - - - - - - ranking = 6keywords = lymphatic (Clic here for more details about this article) |
7/100. A case of inflammatory breast cancer following augmentation mammoplasty with silicone gel implants.A 54-year-old-woman who underwent augmentation mammoplasty with silicone gel implants 30 years previously, visited our hospital with complaints of bloody nipple discharge, redness and itching of her right breast. Cancer of the right breast was diagnosed by dynamic magnetic resonance imaging (MRI) examination with gadolinium (Gd)-DTPA enhancement. Radical mastectomy was subsequently performed. The histopathological findings demonstrated scirrhous and inflammatory breast cancer with invasion of dermal lymphatics.- - - - - - - - - - ranking = 1keywords = lymphatic (Clic here for more details about this article) |
8/100. Metastases to breast simulating ductal carcinoma in situ: report of two cases and review of the literature.The breast is an uncommon site for metastases. Nevertheless, it is important to differentiate primary from secondary tumors of the breast, because clinical management and expected outcomes are vastly different. We report two examples of tumors with a papillary histologic pattern metastasizing to the breast. One of the cases occurred in a 31-year-old woman with a primary renal cell carcinoma, the other was in a 42-year-old woman with an ovarian papillary serous adenocarcinoma. In the first case, the patient's previous history of cancer was not known to the pathologist. The cases highlight the difficulty in distinguishing primary from metastatic tumors in the breast. In both cases the tumors infiltrated in a pattern that mimicked in situ ductal carcinoma changes. Additionally, in both cases, the metastasizing tumor was unusual with the tumor cells diffusely permeating the lymphatic spaces, not in a solid mass. These cases and a review of the literature indicated that breast metastases, although rare, must be recognized and differentiated from primary breast tumors to avoid unnecessary radical surgery to the breast. Moreover, the presence of changes similar to in situ carcinoma of the breast are not conclusive evidence that one is evaluating a primary breast carcinoma. When there is any unusual histomorphology, a good degree of suspicion is necessary.

9/100. Excellent response to gemcitabine in a massively pre-treated woman with extensive cutaneous involvement after recurrence of breast cancer.A 50-year-old woman presented with local relapse of breast cancer 6 years after partial mastectomy. Relapse was accompanied by extended skin induration due to tumor cell embolization of dermal lymphatics. During the following years the patient was exposed to 11 different anti-tumor regimens including 13 cytotoxic drugs (including alkylating agents, antitumor antibiotics, vinca alcaloids, epipodophyllotoxins, and taxanes), 4 anti-hormonal, and 2 immunologic attempts. paclitaxel achieved a prolonged local improvement for some 7 months, but further various treatments were ineffective. At that time gemcitabine therapy was initiated and tumor infiltration of the skin was visibly diminished only 2 weeks later. After that tumor regressed further for 5 months and remained stable with continued doses of gemcitabine during much of the woman's last year. The patient died of acute myeloid leukemia (AML) 4 years after the local recurrence of breast cancer. Since multiple treatments using a plethora of aggressive cytotoxic drugs may render several classes of chemotherapy agents ineffective due to cross-resistance, it seems advisable to select mild agents that are not subject to multidrug resistance mechanisms and display a unique mode of action as demonstrated in this case by gemcitabine.- - - - - - - - - - ranking = 1keywords = lymphatic (Clic here for more details about this article) |
10/100. lymphoscintigraphy in breast cancer: the value of breast lymphoscintigraphy in breast sentinel node staging.A 28-year-old woman with an infiltrating ductal carcinoma in the upper outer quadrant of the left breast diagnosed by excisional biopsy underwent lumpectomy, intraoperative lymphatic mapping, and sentinel node dissection. This was followed by an immediate completion axillary node dissection using a hand-held gamma probe and isosulfan blue to map the lymphatics. Preoperative breast lymphoscintigraphy showed drainage into the axilla and an apparent area of radiocolloid accumulation in the inferior hemisphere of the left breast. Because our protocol called only for removal of axillary sentinel nodes, the inferior hemisphere radiocolloid accumulation was not removed. The patient did not complete local regional therapy with breast irradiation and developed a mass in the inferior hemisphere of the left breast, which on biopsy was shown to be metastatic breast cancer in an intramammary lymph node. This case illustrates the potential value of breast lymphoscintograms to identify unusual sites of lymphatic drainage that may prove to be clinically relevant.- - - - - - - - - - ranking = 3keywords = lymphatic (Clic here for more details about this article) |
