Determination of Factors Associated with Upstage in Atypical Ductal Hyperplasia to Identify Low-Risk Patients Where Active Surveillance May be an Alternative.

Background: Excision is routinely recommended for atypical ductal hyperplasia (ADH) found on core biopsy given cancer upstage rates of near 20%. Identifying a cohort at low-risk for upstage may avoid low-value surgery. Objectives were to elucidate factors predictive of upstage in ADH, specifically near-complete core sampling, to potentially define a group at low upstage risk.

Superficial angiomyxoma of the breast in a 16-year-old girl without carney's complex: A case report.

Superficial angiomyxoma (SA) is a rare benign soft-tissue tumor, arising sporadically or as the earliest manifestation of Carney's complex. When it arises sporadically, the breast is infrequently involved with only few cases reported in the literature. Key imaging findings include T2 signal hyperintensity on MRI and hypervascularity.
