Case Clinical history Requester

Case 1


Breast biopsy for architectural distortion. Please compare and contrast the circled epithelial proliferations (cell size polarity monotony). How would each stain for Keratin 5/6 and ER? Tlr28

Case 2


Breast tissue adjacent to a low-grade IDC. Classify the circled proliferation and describe the spectrum of cytologic features. (bonus: what is going on with that mucin near the single black line?) Tlr28

Case 3


Identify the anatomic structure and classify/describe the epithelial proliferation. Tlr28

Case 4


Identify the anatomic structure and underlying process. Describe the cellular proliferation. Final diagnosis? Tlr28

Case 5


Section from a 10 cm palpable breast mass. Super busy slide -- what histologic features differentiate true invasive carcinoma from mimics such as biopsy tract displacement and radial scars? Tlr28

Case 6


35-y/o with 4cm breast mass. Describe the tissue. Is it concordant? Tlr28

Case 7


70-y/o-female with a small mass. Tlr28

Case 8


50-y/o-female with new left breast calcifications. History of grade 1 DCIS. Tlr28

Case 9


Describe the proliferation. Final diagnosis? Tlr28
