Solid papillary carcinoma (SPC) is a rare neoplasm of the breast showing a distinct morphology, neuroendocrine differentiation and should be divided into invasive and in situ subtype according to the current 2012 WHO classification of breast tumors. Here, we describe a case of a pure SPC, invasive-type, in a 31-years old female with an associated mammary Paget's disease (MPD) of the nipple showing a rare, CK7-negative immune phenotype, which has not been reported so far. This unusual differential diagnosis should be added to the rare condition of CK7-negative Paget's disease of the breast and complement a new feature to the characterization of SPC.

Declining autopsy numbers have a significant influence on cancer statistics. The rate of newly discovered tumors in autopsies in Switzerland decreased from 42% in 1980 to 17% in 2010. Pediatric autopsies are an important tool for quality assurance of medical diagnostics in neonatology and pediatrics in Switzerland, but the rate of autopsies carried out is also declining. Postmortem magnetic resonance imaging (MRI) examinations (virtopsy) could increase the acceptance of the parents for an autopsy in the future. Autopsies make an important contribution in research and in documentation of therapy-associated side effects and they are an important component of further education of the upcoming medical generations.
