6 FAQs about [Solid nodules containing scattered fibrovascular cores]

What does solid papillary carcinoma look like?

Solid papillary carcinoma. Portions of two circumscribed nodules of solid papillary carcinoma are seen. The nodules are composed of a uniform population of ovoid to spindle-shaped epithelial cells growing in a solid pattern. Fibrovascular cores are evident. Absence of myoepithelial cells within the cellular proliferation is characteristic.

What is a fibrovascular scaffold (SPC)?

Histologically, SPC is composed of expansile solid nodules with interspersed delicate fibrovascular cores that appear to form the scaffold on which a monotonous population of epithelial cells proliferate (Fig. 14). The epithelial cells show round to spindled nuclei of low to at most intermediate grade atypia.

What is a rosette-like structure in fibrovascular nodules?

Extracellular mucin, microcystic/microglandular spaces, clusters of foamy macrophages, and microcalcifications may also be present within the solid nodules [69, 75]. Often, the epithelial cells palisade around fibrovascular cores forming rosette-like structures (Fig. 16).

What causes cellular palisading around fibrovascular cores?

Cellular palisading around fibrovascular cores is common. Streaming growth pattern is frequently seen in cases with spindle cells. Microcystic spaces are occasionally present. Frequently, the solid cellular nodules lack surrounding myoepithelial cells.

What are solitary encapsulated papillary hyperplastic nodules (papillary adenoma)?

Solitary encapsulated papillary hyperplastic nodules (“papillary adenoma”) occur frequently in children and teenagers, and some are hyperfunctioning on radionuclide scan (18,19). Cystic change is common in these lesions, and on light microscopy the papillae are often oriented towards the center of the cyst.

Are intranuclear grooves present in papillary hyperplastic nodules (PTC)?

When present, the nucleoli in PTC are usually eccentrically located and inconspicuous (4). Intranuclear grooves can occur in papillary hyperplastic nodules; however, other features of papillary carcinoma such as nuclear membrane irregularities, chromatin clearing, and well-formed intranuclear inclusions are not seen (Figs. 3 C and 3 D) (2,17).
