From: A case of invasive micropapillary carcinoma of the breast involving extensive lymph node metastasis
Pathological findings of H & E staining. (a,b) The primary lesion had a micropapillary component and clusters of carcinoma cells floating in extracellular mucin pools. The histological diagnosis was IMPC with mucin production. (a) × 40 and (b) × 100 and × 400 (in the square) magnification. (c,d) The metastatic lymph nodes showed similar pathological features as the primary lesion. (c) × 40 and (d) × 100 magnification. H & E, hematoxylin and eosin; IMPC, invasive micropapillary carcinoma.
