Peripheral slit-like spaces and a glomeruloid architecture are indicative of usual ductal hyperplasia, until they're not.

Here's some glomeruloid intermediate-grade ductal carcinoma in situ for your eyes to feast on.

Large nests of tumor cells at the leading edge of a tumor with in situ-like morphology are not in situ if they follow the stellate configuration of the infiltrating mass.

This is especially true if a small duct-person is recoiling in fear at the sight of the incoming hordes of…

To you, what makes a human being suffer the most?

Two lobular units. What's the difference between them?

Two examples of breast cancer with such bland neoplastic elements it would be almost impossible to diagnose them as malignant out of context. The second image is particularly interesting to me as it shows a unique case of mucinous carcinoma with an epithelial component consisting…

When I was young and hadn't decided yet what I wanted to do with myself, I took a liking to modern physics. I read a few books and enjoyed every second of undergraduate modern physics courses, so much so that I would not have hesitated on a career in astrophysics had I been smart…

Benign morphology, almost benign biology in the breast, often deadly biology in the salivary gland.

The conundrums of neoplasia will never be resolved.

Needless to say, women's contributions to pathology and medicine are immense, especially in the face of centuries of oppressive patriarchy and relegation to the backseat of science and progress.

Here's a short list of eponymous women in pathology, one that barely scratches the…

It is wise to remember (and remind clinicians) that morphologic overlap in pathology is a rule that cannot be broken. Keeping an open mind about unconventional patterns of disease and recalling them for future reference is the very essence of expertise.

Behold the gynecomastoid…
