Microlobulated Question

[Galsal59]

Has anyone had a breast mass with a microlobulated margin that turned out to be benign?

Thanks!

Well, I haven't. But I have found some info that might help you:

One has to rely upon an array of findings to evaluate solid breast lesions and call it benign or malignant. No characteristics are absolutely specific and it is impossible to distinguish all benign from all solid breast nodules using sonographic criteria. However sonographic criteria to be looked for are :

Shape and margin of the lesion : The shape of a mass can be described as round, oval, lobulated or irregular. Round and oval shapes are suggestive of benign masses. As long as there are fewer than three lobulations, the chances of malignancy is very less. The presence of greater than three lobulations is an indeterminate feature. Irregular shape is suspicious of malignancy. The margin of the lesion reflects the demarcation of the mass with surrounding tissue. It can be smooth, microlobulated, irregular or spiculated. Gentle bilobulated or trilobulated margins are considered smooth. Presence of 2 or 3 gentle smooth, circumscribed and well-encapsulated lobulation strongly favours a benign etiology over cancer. The presence of many small lobulations, that is microlobulations, on surface of solid breast lesion is suspicious of malignancy. Numerous lobulations give the lesion a pleomorphic shape. Microlobulations are frequently associated with angular margins.

and this one:

Invasive breast carcinoma

According to the study of Rahbar (3) 2D US features that characterize lesions as malignant are irregular shape (61% malignant), microlobulated (67% malignant), spiculated (67% malignant) and a width-to-depth (anteroposterior dimension) ratio of 1.4 or less (40% malignant). Most of the time the tumor center is characterized by a homogenous echo-poor fibrohyalinosis followed by a dorsal shadowing due to ultrasound energy absorption. The echo-rich margins are the expression of many different tissue components of tumor cells, fibrous strands, fatty tissue and surrounding glandular parenchyma indicating the tumorous growth and infiltration zone. Mammography clearly shows this stellate infiltration pattern with the architectural distortion of the neighbouring structures.

What I'm finding is that a microlobulated margin of a breast lesion seems to show a two thirds likelihood of malignancy. Benign findings occur about 1/3 of the time. I'm hoping you are in the 1/3 category, sal.

Thanks! That's pretty much what I've been finding myself. Just wanted to get some other perspectives.

My biopsy is scheduled for the 20th. The only ones that get in sooner are those that have had b/c previously or have large masses, etc. Fwiw, my Birad was a 4 and the radiologist was calling my Dr within approximately 1/2 hour upon my departure from the ultrasound. I was scheduled to see a surgeon the next day. Sure seems bizarre to be placed on such a rushed track to have to wait for so long for the biopsy.

St. Joseph Womens Hospital Breast Center here in Tampa has a "Fast Track". I was placed on that soon as the BIRAD was known.

Toodles,

Still waiting to find out the biopsy results. It was done on Tuesday this past week and the appointment to review the results is set for this coming Wednesday.

It REALLY irks me that the hospital said the Dr would have the results in 2-3 days. When I scheduled the appointment and it was set for over a week after the biopsy, I questioned that. I was told that usually even then they still don't have the results and have to call for it.

Hmmmmm
