“…The only tumor in our series which was histopathologically diagnosed as mucinous carcinoma had regular margins at mammography and simulated a benign lesion. This finding is in accordance with the literature (3,5,6).…”

Aim: The aim of this study is to determine the diagnostic value of mammography and ultrasonography for differentiating benign and malignant breast masses.Material and Methods: Fifty-one patients who had palpable breast masses were evaluated with both mammography and US. The detected lesions were classified as benign or malignant according to their imaging features and these results were evaluated according to the histopathological reports.Results: Histopathologically, 28 of the 51 breast masses (54.9%) were reported as benign and 23 (45.1%) as malignant. The sensitivity and specificity of mammography were 81.4% and 90.4% for benign masses. The sensitivity and specificity of US for benign masses were 85.7% and 82.6%. The sensitivity and specificity of mammography for malign masses were 90.9% and 81.4%. The sensitivity and specificity of US for malignant masses were 78.2% and 85.7%.Conclusion: Although ultrasonography is a valuable imaging method for the differentiation of solid -cystic breast masses, mammography is superior to ultrasonography for benignmalignant differentiation.Key Words: Mammography, Ultrasonography, Breast mass Amaç: Mammografi ve ultrasonografinin, meme kitlelerinde benign-malign ayrımı yapmaktaki değerini belirlemektir.Gereç ve Yöntem: Palpabl meme kitlesi olan ve bu nedenle ultrasonografi ve mammografi incelemesi yapılan 51 olgu çalıșmaya dahil edilmiștir. İzlenen kitleler özelliklerine göre benignmalign olarak ayrılmıș, bu sonuçlar histopatoloji raporları ile karșılaștırılmıștır. Bulgular: Histopatoloji sonuçlarında 51 meme kitlesinin 28'i (%54.9) benign, 23'ü (%45.1) malign olarak raporlanmıștır. Benign kitlelerde mamografinin sensitivite ve spesifisitesi %81.4 ve %90.4 olarak belirlenmiștir. Benign kitlelerde US'nin sensitivite ve spesifisitesi ise %85.7 ve %82.6 olarak hesaplanmıștır. Malign kitlelerde mamografinin sensitivite ve spesifisitesi %90.9 ve %81.4 olarak belirlenmiștir. Malign kitlelerde US'nin sensitivite ve spesifisitesi ise %78.2 ve %85.7 olarak hesaplanmıștır.

“…Mammographic features -low density, oval or round shape, and circumscribed or slightly 3). An association between poorly differentiated margins on mammograms and a decreasing volume of mucin has previously been suggested by Conant et al (10), which was later supported by the finding of more irregular margins in mixedtype mucinous carcinoma in comparison with pure ones and a correlation of poorly-defined margins with histologic grade (2,7,9,17). Previous articles have reported sonographic appearances of mucinous carcinoma in a relatively small patient series.…”

Imaging findings and accuracy of core needle biopsy in mucinous carcinoma of the breast

CNB was found to be a highly reliable diagnostic tool for diagnosing mucinous carcinoma in this selected material. US findings of pure mucinous carcinoma were variable, however, all reached BI-RADS 4 category. The presence of posterior acoustic enhancement beneath a solid breast lesion should raise suspicion of mucinous carcinoma. Most of the tumors appeared as BI-RADS 4 lesions in US and in mammography thus making both a useful tool for raising a suspicion of malignancy in mucinous cancers.

“…Cardenosa et al [8] reported ten cases of mucinous breast cancer whose main mammographic features consisted of poorly defined, lobulated masses. Later, Conant et al [9] found a correlation between the quantity of mucin and the mammographic findings in their 37 cases: The higher the percentages of extracellular mucin, the less aggressive was its appearance on mammograms. Wilson et al [10] studied the mammographic characteristics of 15 pure and 5 mixed mucinous carcinomas, and found that pure mucinous tumors usually showed circumscribed or lobulated margins on mammograms, as the result of their microscopically circumscribed margins.…”

“…Previous articles have reported normal mammograms in 5.4 % [9] to 17 % [11] of cases. It has even been suggested that tumors that produce profuse extracellular mucin may be less dense radiologically than more scirrhous tumors [9]. Nevertheless, it is well known that breast neoplasms may be invisible on mammography.…”

Mucinous breast carcinoma showing as a cluster of suspicious microcalcifications on mammography

We report a case of mucinous breast carcinoma whose mammographic features consisted of a suspicious cluster of microcalcifications as the unique sign of malignancy. The lesion was non-palpable and measured approximately 2 cm at the greatest diameter. The microcalcifications showed several morphologies: round, pleomorphic, and fine shapes were identified. The total number of microcalcifications was > 30 and the number per square centimeter varied from 10 to 20. The histological calcifications showed good correlation with the mammographic ones and were localized predominantly at the periphery of the tumor inside ducts with ductal carcinoma in situ or in the acellular mucin. Two types were observed: psammomatous and gross-irregular calcifications. To our knowledge, only one case with similar findings has been reported previously.
