1/7. Diagnostic difficulties in spontaneous infarction of a fibroadenoma in an adolescent: case report.Spontaneous infarction is an uncommon complication occurring in fibroadenoma of the breast. Although infarction following fine-needle aspiration has been reported in the literature, to the best of our knowledge this is the first reported case where infarction was encountered on first-time aspiration. It is necessary to distinguish infarcted fibroadenoma from mastitis, duct ectasia, mammary tuberculosis, and carcinoma on cytology smears. Lack of knowledge of this entity may lead to an erroneous diagnosis of inflammatory lesion or carcinoma. We report the first case of cytological and histological findings in spontaneous infarction of fibroadenoma in 13-yr-old female.- - - - - - - - - - ranking = 1keywords = mastitis (Clic here for more details about this article) |
2/7. A case of granulomatous mastitis mimicking breast carcinoma.A 58-year-old woman presenting with idiopathic granulomatous mastitis mimicking breast carcinoma is described. The mass was elastic, hard and painless, and located in the upper outer quadrant of the right breast. Fine needle aspiration cytology did not provide any diagnostic information. mammography, ultrasonography and magnetic resonance imaging (MRI) strongly suggested malignancy. Excisional biopsy was performed for definitive diagnosis, and idiopathic granulomatous mastitis was demonstrated histopathologically. Neither wound complication nor recurrence has been identified in the patient, although corticosteroids were not used post operatively. We reviewed the literature, and found that our present case is rare in older patients, and that mammography, ultrasonography and MRI provide little information for differentiating between granulomatous mastitis and carcinoma.- - - - - - - - - - ranking = 7keywords = mastitis (Clic here for more details about this article) |
3/7. Histopathology of tumour associated sarcoid-like stromal reaction in breast cancer. An analysis of 5 cases with immunohistochemical investigations.In 5 cases of invasive ductal and lobular carcinoma of the breast multiple epithelioid and giant cell containing granulomas were detected, localized mainly in circumferential regions, but also in the center of the carcinomas. These granulomas were interpreted as sarcoid-like stromal reactions, occurring as sarcoid-like lesions in uni- and bilateral primaries, in a recurrent tumour, and also in axillary lymph nodes. Histopathologically, these granulomas were not quite uniform, some of them corresponding to typical sarcoidosis, others showing marked proliferations of epithelioid or giant cells or containing fibrinoid exudate or necroses. The granulomas were surrounded by dense infiltrates of mononuclear cells. tuberculosis and mycosis was excluded. There were no hints of generalized sarcoidosis. Pathogenetically, these are reactions in the tumour stroma of varying intensity, and are not caused by necroses of the tumour tissue nor by microbial infections. Such tumour-associated sarcoid-like stroma reactions are interpreted as a T-cell mediated immune response to an antigen expression of the carcinoma acting as the local trigger; in 2 cases they were connected with sarcoid-like lesions of the axillary lymph nodes. Their occurrence in bilateral carcinoma of the breast points to an immunological disposition for this special kind of host-versus-tumour response. The intensity of these changes in a recurrent tumour reflects an immunological hypersensitivity reaction. The pathogenetic and differential diagnostic aspects of epithelioid granulomas of the female breast in chronic granulomatous mastitis, panniculitis, foreign body reaction, rare infections, and in therapeutically induced sarcoidosis are described and discussed.- - - - - - - - - - ranking = 1keywords = mastitis (Clic here for more details about this article) |
4/7. granulomatous mastitis caused by histoplasma and mimicking inflammatory breast carcinoma.Two cases of a lobular, necrotizing granulomatous process causing a unilateral painful breast mass mimicking carcinoma are presented for comparison. While the morphologic appearance in each case was that of lobular granulomatous mastitis, the etiologic agent in one case appeared to be histoplasma capsulatum, based on Grocott methenamine silver staining, and represents the second reported case of histoplasmosis involving only breast parenchyma. awareness of the rare entity, granulomatous mastitis, is important for the pathologist because the definitive diagnosis is made microscopically. Thorough evaluation of the breast tissue is essential for its management and should eventually contribute to the clarification of its etiology.- - - - - - - - - - ranking = 6keywords = mastitis (Clic here for more details about this article) |
5/7. tuberculosis of the breast: rare but still extant. review of the literature and report of an additional case.tuberculosis of the breast is a rare malady that is usually manifested by a unilateral mass suggestive of carcinoma or sometimes of abscess. mammography also suggests carcinoma in most instances. However, at operation, the discovery of necrotic tissue or abscess may lead to the suspicion of infectious or inflammatory disease rather than neoplasm. The diagnosis of tuberculosis may be established by the demonstration of acid-fast bacilli in excised tissue, by culture studies, or by guinea pig inoculation; however, the diagnosis is usually not suspected. In the past, mastectomy was the usual treatment. Today, successful treatment combines antituberculous drug therapy with the removal of infected breast tissue. The prognosis for complete cure is excellent. One case of secondary tuberculous mastitis has been reported herein. The patient, an Egyptian woman residing in the united states since 1973, was treated in egypt for pulmonary tuberculosis at age 17. She presented in 1982 with a breast mass that mimicked carcinoma on physical examination and mammograms, but excisional biopsy and histologic examination revealed a breast abscess that contained caseous material and a solitary acid-fast bacillus. The patient was cured of her disease after appropriate operation and a course of antituberculous drugs. This has been the only documented case of mammary tuberculosis at our institution. Despite its rarity, tuberculosis of the breast should not be forgotten in this age of world travel.- - - - - - - - - - ranking = 1keywords = mastitis (Clic here for more details about this article) |
6/7. breast tumour. An unusual manifestation of a carcinoma of the stomach.A 59-year-old woman presented with an infiltration in the left breast and a large mass of enlarged lymph nodes on the left side of the neck. Radiological and histological examinations showed that the breast involvement was a mastitis carcinomatosa secondary to a carcinoma of the stomach. A review of the literature revealed ten earlier cases of metastases to the breast from a primary carcinoma of the stomach. The cases are discussed especially concerning the way of tumour spread.- - - - - - - - - - ranking = 1keywords = mastitis (Clic here for more details about this article) |
7/7. Idiopathic granulomatous mastitis: case report and review of the literature.We report a case of idiopathic granulomatous mastitis in a 35-year-old Japanese woman, who came to our hospital complaining of a tender mass in her right breast. Because the results of initial aspiration cytology were considered highly suspicious for carcinoma, modified radical mastectomy was performed. However, the final histological diagnosis was granulomatous lobular mastitis with no evidence of malignancy. Idiopathic granulomatous mastitis is a rare inflammatory breast disease of unknown etiology. Since the clinical manifestations are similar to those of mammary carcinoma, this condition has been misdiagnosed as carcinoma and treated as such. A review of the literature revealed that idiopathic granulomatous mastitis has tended to occur in young patients with a history of childbirth or oral contraceptive usage. Clinical or imaging diagnosis has often been difficult. Complete resection or corticosteroid therapy can be recommended as the optimal treatment. Since 38% of patients experience recurrence, long-term follow-up is indicated.- - - - - - - - - - ranking = 8keywords = mastitis (Clic here for more details about this article) |
