Read a breast fine needle aspirate
Nine units and a capstone, on real patches from 13 hospitals, taught by the International Academy of Cytology Yokohama criteria. You commit to an answer before anything is revealed, and the measurements answer second.
New to the microscope
You have never looked at a smear. Start at the beginning: what an aspirate is, what the stains show, and how big a cell is at this scale.
You already read slides
Twenty classification items from a held out pool, balanced across the categories and both stains. It sets your baseline and opens the drills at your level.

The units
Each unit is a teaching page and a drill set. A family of items counts as mastered after three correct answers in a row, each inside the target response time.
- U0The smear
Read the smear itself: what an aspirate is, what each stain shows, how big things are at this scale, and what makes a smear adequate.
Not started - U1Architecture and cohesion
Read the low power pattern: cohesive fragments and flat sheets against crowded fragments and dispersed single cells.
Not started - U2The second population
Find the second, smaller, darker population inside the fragments and in the background, and notice when it has gone.
Not started - U3Nuclear size and anisonucleosis
Judge nuclear size against the scale bar and against this library's own bands, and see what the three largest nuclei carry.
Not started - U4The nuclear membrane
Read the edge of the nucleus, and see what smoothness, concavity and concave points measure on the traced outline.
Not started - U5Chromatin and nucleoli
Read the inside of the nucleus, and see what a texture number can carry and what it cannot.
Not started - U6The background
Name the lesion from what lies between the cells: stroma, apocrine sheets, cyst fluid, inflammation, fat and mucin.
Not started - U7The categories
Place a patch in C1 to C5, and say the risk of malignancy and the management that follows.
Not started - U8The machine as a second reader
See which criteria the eight inputs touch, where the model and the expert disagree, and which criterion decides it.

The rest of the course
- AtlasEvery case in the library, browsed by category, stain and report line. The one place a picture is labelled before you answer.
- Screen a slideThe capstone. Screen a whole slide at low power, click where you would go high, and reach a category.
- ProgressAccuracy, median response time, false negatives on their own line, and your data to export, import or delete.
- AboutThe objectives, the sources, the dataset and the sites it came from, and how the schedule works.
