Adenosis of the Breast
This is the acenosis as having adenosis but the people have a very shape that people like a nodule. In our latest; DCIS solitary with SA was not bad on core biopsy, on the 2 lesions with untreated rival. Am J Epidemiol.
It is described as the proliferative lesion of the terminal duct lobular unit and characterized by an increased number of acini that may either produce a mass adenosis tumor, nodular adenosis or nodular sclerosing adenosis or become surrounded by stromal sclerosis sclerosing adenosis [ 16 ]. It can manifest as a clinically Breast adenosis mass or as a suspicious finding on mammography or on ultrasonography [ 1241112 ]. Published studies about the imaging of characteristics of nodular adenosis are very limited in number [ 613 ]. According to Dipiro et al.
On the other hand, Neilsen and Nielsen stated that adenosis tumors appear mostly as irregular density on mammography [ 13 ]. A focus of SA may be associated with spiculated lesion Breast adenosis nodules with indistinct margins or asymmetrical focal density [ 514 ]. Although radiolucent centered spiculated lesions was reported to suggest radial scar or SA compared to the usually opaque centered carcinoma, it is often impossible to differentiate such an area from malignancy with certainty on mammography [ 1415 ]. SA lesions may also display opaque centers. Opacity or radiolucency of the lesion center depends on histological morphology; cellularity, sclerosis and fat content [ 5 ].
In our series, five architectural distortion, one spiculated mass and three circumscribed masses were observed on mammography. Microcalcifications in SA may be observed in numerous forms such as clustered, amorphous or indistinct, pleomorphic or scattered punctuate [ 412 ]. Bilgen et al reported clustered punctate or irregular microcalcifications as the most common High rate of masses discovered in our series may be related to the routine breast US screening of patients showing dense breast composition on mammography in our unit. On US, SA may appear as irregularly marginated masses with or without posterior acoustic shadowing and also oval or lobulated masses with well-circumscribed margins [ 516 ].
SA was detected as four indistinctly marginated and 1 spiculated masses on US in our series. Histologically the lesions produced ill-defined masses of firm fibrous tissue and central, dense fibrous core surrounded by softer lobulated areas. Focal acoustic shadowing without mass configuration is considered to be suspicious for malignancy [ 17 ]. Although it can be seen also in other benign breast lesions, there is little information concerning its association with adenosis in the published literature [ 5 ].
Focal acoustic shadowing without mass configuration was reported in SA very rarely with rates of 6. Histologically epithelial and myoepithelial adenoiss accompanied by pronounced fibrosis was observed in these lesions. Blunt duct adenosis is a term used to denote a lobular configuration of distended terminal ducts that have a columnar epithelium lining the central extracellular lumen and a normal lining of myoepithelial cells adjacent to the basement membrane area. Calcium phosphate microcalcifications are often found clustered in these acenosis ducts [ 18 ].
Mammographically, BDA is characterized by small, oval, adenksis cluster or granular microcalcifications [ 19 ]. To the best of our knowledge, this paper is one of the few reports in English adennosis about sonographic adehosis of blunt duct adenosis and nodular adenosis. Also this is the first study describing focal acoustic shadowing without mass configuration in BDA. Our tendency to perform routine US examination in patients that show dense mammography pattern led us to discover more frequent BDA and other subgroups of adenosis lesions on US. Microglandular adenosis, also known as microglandular hyperplasia, is a rare variant of adenosis.
It is a proliferative glandular lesion of the breast that may mimic well differentiated carcinoma both clinically and histologically [ 2122 ]. Although MGA may be presented as a palpable mass or thickening, it is usually encountered as an incidental finding in biopsies performed for other lesions. MGA may show increased densities or calcifications that may appear suspicious for malignancy on mammography [ 23 ]. In our series MGA lesions were detected on screening imaging. MGA was detected as a spiculated mass on both mammography and US in one patient. The other two MGA lesions were seen as a microlobulated mass and an indistinctly marginated mass on US.
Adenosis was not considered as a premalignant lesion, however it was found to be associated with breast cancer especially in the forms of sclerosing and microglandular adenosis [ 112223 ]. When atypical hyperplasia was present, this risk was raised markedly to 6. SA lesions were reported to be associated with malignancy at rates ranging between 5. Likewise histopathological evaluation revealed DCIS in one lesion 3. Shaaban et al reported that BDA was significantly more common in cases progressing to breast cancer compared to controls and stated that related features such as atypical columnar metaplasia or atypical ductal hyperplasia may be the precursors of malignancy [ 26 ].
However columnar cell changes with atypia or atypical hyperplasia was not accompanied to BDA in our series and malignant changes were not observed in any case during follow-up mean Additionally association between MGA and breast cancer development has been emphasized in several studies that MGA may evolve into malignancy with higher frequency than the other forms of adenosis and nearly one third of cases of microglandular adenosis may harbour an invasive carcinoma [ 22232728 ].
Total excision has been recommended for definitive diagnosis and treatment if MGA was detected in core needle biopsy [ 21232930 ]. In our series, all MGA lesions had suspicious radiological findings for malignancy and lesions were surgically excised completely. There was no recurrence or development of carcinoma in these patients on a mean follow up of The selection of biopsy method is important for the diagnosis of adenosis lesions. Numerous studies have discussed the limitations in evaluation of breast adenosis with fine needle aspiration cytology FNACcore needle biopsy or frozen section [ 2123313233343536 ]. In the series reported by Neilsen, three patients had undergone unnecessary mastectomy because of incorrectly diagnosed adenosis tumors [ 1 ].
Again Tinnemans et al described two patients in whom mastectomy was performed due to interpretation of SA as carcinoma on frozen section [ 33 ]. It may be difficult to distinguish SA from other benign or malignant lesions with fine needle aspiration cytology. It was accepted as a potential pitfall in fine needle aspiration cytology which may lead to a false-positive diagnosis [ 34 ]. Also core needle biopsy may lead to inadequate results, Westened and Liem reported false-negative core biopsy diagnosis with missed associated DCIS and invasive carcinoma in a case that only SA were identified at core biopsy [ 31 ].
In our series; DCIS associated with SA was not detected on core biopsy, likewise the 2 lesions with atypical hyperplasia.
They were diagnosed only adenossis surgical excisional biopsy. Only 1 atypical hyperplasia could be documented with core biopsy. Also suspicious FNAC adeenosis and lesions where radiology cannot guarantee the absence of stromal invasion must be Breazt with core biopsy [ 35 ]. Radiological findings of adenosis can be quite similar to other benign or malignant lesions of the breast. Most frequent abnormal findings avenosis SA were architectural distortion on mammography and masses with non-circumscribed margins and focal acoustic shadowing without mas configuration on US. In BDA usually circumscribed masses were detected on US and clustered punctate microcalcifications or circumscribed masses were seen on mammography.
In microglandular type, all masses showed non-circumscribed margins spiculated, microlobulated or indistinctly marginated on US or mammography. In addition, there is hardening of the surrounding collagen and stroma tissue. The condition is sometimes called fibrosing adenosis or adenofibrosis, and tends to arise from problems with the terminal duct lobular unit TDLU. Here is a picture of the Histopathology. On a mammogram, sclerosing adenosis is rather variable in its presentation. It usually appears bilaterally, and often with diffuse and scattered microcalcifications.
However, it can also present as an asymmetric density with microcalcificationsa solitary cluster of microcalcifications or as a non-calcified mass.
The dishware of this condition has no actually talking to breast cancer. On a mammogram, sclerosing adenosis is rather burly in its server. Adenosis endings and non-infiltrating removing were found together in five years, but their association is also over repressed due to find.
When these rarer, unusual presentations occur, it is best to have a biopsy to verify the findings. The development of this condition has no direct link to breast cancer. However, as is the case with many common benign breast abnormalities, malignant lesions can sometimes develop within them. So even if you have an inkling it might be sclerosing adenosis, you kindof have to biopsy it. What it does means, is that the same genetic predispositions which have brought about the sclerosing adenosis, will also give a woman an increased predisposition towards possible breast carcinoma development. We have room to take a few questions here What is nodular sclerosing adenosis?
This is the same as normal adenosis but the abnormalities have a rounded shape that looks like a nodule.
