1/6. Malignant phyllodes tumor in the right breast and invasive lobular carcinoma within fibroadenoma in the other: case report.CONTEXT: The malignant variety of the phyllodes tumor is rare. The occurrence of invasive lobular carcinoma within fibroadenoma is rare as well. DESIGN: Case report. CASE REPORT: A 58-year-old black female patient was referred to the Mastology unit of the Department of gynecology, Federal University of Sao Paulo / Escola Paulista de Medicina, in February 1990, presenting an ulcerated tumor in the right breast with fast growth over the preceding six months. She was a virgin, with meno-pause at the age of 45 years and had not undergone hormone replacement treatment. The physical examination showed, in her right breast, an ulcerated tumor of 20 x 30 cm which was not adher-ent to the muscle level, multilobular and with fibroelastic consistency. The axillary lymph nodes were not palpable. The left breast showed a 2 x 3 cm painless, movable nodule, with well-defined edges, and fibroelastic consistency. We performed left-breast mammography, which showed several nodules with well-defined edges, the largest being 2 x 3 cm and exhibiting rough calcification and grouped microcalcifications within it. The patient underwent a frozen biopsy that showed a malignant variant of the phyllodes tumor in the right breast and fibroadenoma in the left one. After that, we performed a total mastectomy in the right breast and an excision biopsy in the left one. paraffin study confirmed the frozen biopsy result from the right breast, yet we observed that in the interior of the fibroadenoma that was removed on the left, there was a focal area of invasive lobular carcinoma measuring 0.4 cm. The patient then underwent a modi-fied radical mastectomy with total axillary lymphadenectomy. None of the 21 dissected lymph nodes showed evidence of metastasis. In the follow-up, the patient evolved asymptomatically and with normal physical and laboratory examination results up to July 1997.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/6. Non-invasive lobular carcinoma within a fibroadenoma, a preoperatively diagnosed case.breast cancer within a fibroadenoma is rare and usually diagnosed postoperatively from pathological specimens. This paper reports a 54-year-old female with non-invasive carcinoma within a fibroadenoma, diagnosed preoperatively. She underwent a medical examination and mastopathy was suspected. On physical examination a mass 2 cm in diameter was palpated in the left breast. ultrasonography showed a mass with smooth margins and uniform internal echoes, but cytology showed malignancy. mammography showed a round mass with distinct margins and no calcification. As fibroadenoma, diagnosed by ultrasonography and mammography, and breast cancer, diagnosed by cytology, were not consistent results several core biopsies were performed. Needle biopsy showed proliferation of atypical epithelial cells; breast cancer within a fibroadenoma was diagnosed. MRI showed a circular mass with distinct, smooth margins and in a dynamic study, the mass showed irregular staining and the presence of early staining. Left lumpectomy and dissection of the left axillary lymph nodes was performed. Histological examination showed non-invasive lobular carcinoma occurring within a fibroadenoma.- - - - - - - - - - ranking = 0.5keywords = physical (Clic here for more details about this article) |
3/6. Typical and atypical Carney's triad presenting with malignant hypertension and papilledema.This report encourages clinicians to consider a diagnosis of Carney's triad in patients with multifocal gastric stromal sarcoma, extraadrenal paraganglioma (predominantly mediastinal), or pulmonary chondroma. The authors conducted a retrospective 20-year survey at the Hospital for Sick Children and identified two children with Carney's triad. One child, presenting atypically with papilledema and fundal hemorrhages from malignant hypertension and benign intracranial hypertension from chronic iron-deficiency anemia, is the second patient ever to date be described with the complete Carney's triad of neoplasms at diagnosis. Another child presented more typically with gastric stromal sarcoma and pulmonary chondroma without paraganglioma. Carney's triad is a rare differential diagnosis for "idiopathic" hypertension or iron-deficiency anemia from chronic gastrointestinal bleeding. If missed, patients with Carney's triad may have the debilitating physical and mental consequences of chronic iron deficiency and may die of untreated prolonged hypertension and metastatic leiomyosarcoma.- - - - - - - - - - ranking = 0.5keywords = physical (Clic here for more details about this article) |
4/6. Unexpected prolonged neuromuscular block after mivacurium: a case report.OBJECTIVE: To present a case of unexpected prolonged apnoea following the administration of mivacurium, a short-acting muscle relaxant and to identify the factors for early diagnosis and management. CLINICAL PRESENTATION AND INTERVENTION: A 19-year-old physically fit lady without personal or family history suggestive of anaesthetic problems had an excision of fibro-adenoma from the breast. She did not recover as quickly as was expected from the anaesthetic, which included the administration of mivacurium. She had prolonged neuromuscular blockade. She was kept ventilated and sedated. Five hours after the last dose of mivacurium, she showed signs of spontaneous respiration and at 6 h she was extubated and fully recovered. It was shown later that the patient had a pseudocholinesterase deficiency. CONCLUSION: pseudocholinesterase deficiency is an uncommon occurrence but should be highly suspected in cases of prolonged paralysis following the administration of a short-acting muscle relaxant. The use of a nerve stimulator is recommended whenever muscle relaxants are used. Muscle relaxants should be used only when facilities for prolonged ventilation are available.- - - - - - - - - - ranking = 0.5keywords = physical (Clic here for more details about this article) |
5/6. fibroadenoma in axillary supernumerary breast: case report.CONTEXT: Supernumerary breast tissue may be affected by the same diseases and alterations that compromise topical breast tissue. Nevertheless, reports of fibroadenoma in supernumerary breast tissue in the axillae are rare. OBJECTIVE: To describe a case of fibroadenoma in an axillary supernumerary breast. DESIGN: Case report. CASE REPORT: A 39-year-old woman was referred to the gynecology and obstetrics outpatient clinic at Hospital Estadual Sumare, complaining of bilateral axillary masses. The patient reported cosmetic problems and local pain and discomfort. On physical examination, alterations compatible with bilateral axillary accessory breasts, without palpable nodules, were observed. Supplementary examinations (mammography and ultrasonography) revealed a 1.1 cm mass in the right axillary breast. The patient underwent resection of the supernumerary breasts and histopathological examination revealed fibroadenoma of the right axillary breast tissue.- - - - - - - - - - ranking = 0.5keywords = physical (Clic here for more details about this article) |
6/6. melanoma metastasis to the breast masquerading as fibroadenoma.BACKGROUND: Although primary malignant breast lesions are common, tumor metastasis to the breast is rare. melanoma metastasis to the breast occurs even more rarely. CASE: In the present case report, we describe an adolescent girl with malignant melanoma metastasis to the breast masquerading as fibroadenoma, in which it was impossible to perform differential diagnosis based only on the physical examination and ultrasonographic evaluation. The definitive diagnosis both of the primary and of the metastatic lesion was reached by immunohistochemistry, which revealed positivity to Mart-1 antibody. CONCLUSION: melanoma metastasizing to the breast is occasionally indistinguishable from a benign lesion at ultrasonographic evaluation. Emphasis should be made on the importance of a correct diagnosis prior to therapeutic management.- - - - - - - - - - ranking = 0.5keywords = physical (Clic here for more details about this article) |
