1/43. heparin-induced thrombocytopenia and fat necrosis of the breast.fat necrosis of the breast is a well-known complication following trauma, surgery, or radiotherapy. The present paper describes a rare case of fat necrosis after heparin-induced thrombocytopenia. The mammographic, sonographic, and MR evaluation and pathologic correlation after a 1-year follow-up period are reported.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
2/43. Muscular hamartoma of the breast: a rare breast lesion containing smooth muscle.hamartoma of the breast is an uncommon entity, usually presenting as a well-demarcated breast mass. Microscopically, the lesion is composed of mammary glandular component, fibrous stroma, adipose tissue, and smooth muscle in variable proportions. Among the variants of breast hamartoma, muscular hamartoma is rare. This lesion should be differentiated from other breast tumors that contain smooth muscle element. We report a breast lesion of a 36-year-old woman diagnosed as a muscular hamartoma in which the muscular component is cellular and some mitotic figures are present. The criteria to distinguish between benign and malignant smooth muscle lesions in the breast, emphasizing mitotic count, are also discussed.- - - - - - - - - - ranking = 0.58072114389322keywords = adipose (Clic here for more details about this article) |
3/43. A case of muscular hamartoma of the breast.We describe a 74-year-old female presenting with a right breast mass. She had found the mass on self-examination. physical examination revealed a 2.2 x 2.5 cm, firm, smooth, and mobile lump in the upper medial portion of the right breast. mammography revealed a well marginated, oval-shaped, and isodense nodule. Calcification was not evident. On ultrasonography, the lesion was 17 x 18 x 9 mm and located 5 mm below the overlying skin. Excisional biopsy under local anesthesia was performed. The tumor was easily excised. Histopathologically, the lesion was composed of intersecting bundles of spindle-shaped smooth muscle cells, and involved peripheral ducts and fat tissue. Immunohistochemical staining showed positivity for alpha-smooth muscle actin (SMA), but was negative for S-100 protein, myoglobin, keratin, and vimentin. From these findings a muscular hamartoma of the breast, a rare subtype of hamartoma, was diagnosed.- - - - - - - - - - ranking = 0.2keywords = fat (Clic here for more details about this article) |
4/43. hamartoma of the breast in a man: first case report.Mammary hamartomas were reported in 0.7% of all benign tumors of the female breast. Histologically breast hamartomas contain lobular breast tissue with various degrees of fibrous, fibrocystic, and adipose tissue. Rare types include muscular (myoid) and cartilage (chondroid) hamartomas. We report a case of muscular hamartoma in a man. A 36-year-old man was admitted to the psychiatric unit with the diagnosis of schizophrenia. The patient complained of a slowly growing mass in his left breast. He denied any discharge from the nipple, but he complained of itching. A 2 cm x 3 cm nontender mass was palpable. There was no evidence of axillary lymphadenopathy. A needle aspiration was nondiagnostic. The excisional biopsy specimen revealed fatty tissue which was edematous and hemorrhagic. Microscopically it showed multiple bundles of muscles organized randomly. Myoid hamartoma was the diagnosis. Mammary hamartoma is considered a female tumor exclusively. Myoid hamartoma has been reported previously in 25 women. We report a myoid hamartoma in a man and, to our knowledge, it is the first and only such case to be reported.- - - - - - - - - - ranking = 0.78072114389322keywords = adipose, fat (Clic here for more details about this article) |
5/43. Localized scleroderma of the breast.We report a 44-year-old patient with right-breast morphea. mammography, MRI and needle biopsy were used for assessment of the case. mammography demonstrated thickening of the skin and the subcutaneous tissue. The MRI showed replacement of the subcutaneous and breast fat by a low signal intensity, non-enhancing tissue. skin biopsy confirmed the histological features of scleroderma.- - - - - - - - - - ranking = 0.2keywords = fat (Clic here for more details about this article) |
6/43. pathology of the breast associated with hiv/AIDS.Breast pathology that is characteristic of patients infected with human immunodeficiency virus (hiv) has not been addressed in the literature. hiv may directly and indirectly affect the glandular, mesenchymal, and intramammary lymphoid tissue in seropositive patients. Likely infections in this setting include tuberculous mastitis and pyogenic abscesses that may lead to fatal septicemia. Benign stromal changes include gynecomastia, adipose tissue deposition as part of the fat maldistribution syndrome, and pseudoangiomatous stromal hyperplasia. Breast carcinoma in hiv-infected patients occurs at a relatively early age, with increased bilateral disease, unusual histology, and early metastatic spread with a poor outcome. However, the link between breast cancer and hiv remains controversial. Kaposi's sarcoma and non-Hodgkin's lymphoma may also be localized to the breast in patients with acquired immunodeficiency syndrome (AIDS). This article reviews benign and malignant breast diseases that are likely to be encountered in patients with hiv/AIDS.- - - - - - - - - - ranking = 0.98072114389322keywords = adipose, fat (Clic here for more details about this article) |
7/43. MRI of muscular hamartoma of the breast.Muscular hamartoma is a well-demarcated tumour composed of smooth muscle and adipose tissue. We report the MRI findings of a patient with benign breast neoplasm. To the best of our knowledge, its appearance has not been previously reported.- - - - - - - - - - ranking = 0.58072114389322keywords = adipose (Clic here for more details about this article) |
8/43. A case of breast sparganosis.A 29-year-old Korean woman visited the Department of Surgery in MizMedi Hospital with a palpable itching mass on the right breast that had existed for the past 7 months. She had no history to eat either frogs or snakes, but had the history of drinking impure water. Sonography revealed a serpiginous hypoechoic tubular structure associated with partial fat necrosis in breast parenchymal layer and subcutaneous fat layer. It also revealed oval cystic lesions. At operation, an ivory white opaque ribbon-like worm that measured 16.5 cm in length and 0.5 cm in width was extracted. Anti-sparganum specific serum IgG level in the patient's serum (absorbance = 0.71), measured by ELISA, was found to be significantly higher than those of normal controls (cut off point = 0.21). Sonography and ELISA appear to be helpful to diagnose sparganosis. Breast sparganosis is rarely found throughout the world.- - - - - - - - - - ranking = 0.4keywords = fat (Clic here for more details about this article) |
9/43. sarcoidosis of the breast.We report a case of sarcoidosis of the breast in a 31-year-old woman who presented with a palpable breast mass. The mammography showed a spiculated mass without any microcalcifications. Ultrasonogram showed a hypoechoic mass. Computed tomography showed a spiculated nodule. T2-weighted MR images with fat-suppression technique showed a mass with irregular border that appeared to be an accumulation of small nodules. gadolinium-enhanced dynamic study showed gradually increasing signal intensity. She underwent excisional biopsy and the pathological findings were consistent with that of sarcoidosis. The MRI findings were well correlated with histopathological appearance.- - - - - - - - - - ranking = 0.2keywords = fat (Clic here for more details about this article) |
10/43. Imaging findings in Mondor's disease.Mondor's disease, or acute thrombophlebitis of superficial veins of the breast, occurs rarely, and little information is available in the medical literature on imaging findings in this disease. We present the case of a 59-year-old woman who underwent evaluation of a palpable, painful cord in her left breast associated with discoloration of the overlying skin. mammography revealed a 10-cm-long linear density in her left breast. Gray-scale sonography showed a noncompressible, hypoechoic, undulating tubular structure in the subcutaneous fat. color Doppler imaging revealed no flow signal in this structure, although we observed arterial flow signals adjacent to it. We diagnosed Mondor's disease and treated the patient symptomatically; 6-week follow-up examinations demonstrated resolution of the venous thrombosis. The use of sonography, particularly color Doppler imaging, can aid in diagnosing Mondor's disease and in monitoring its resolution.- - - - - - - - - - ranking = 0.2keywords = fat (Clic here for more details about this article) |
