HighlightsEndometrial stromal sarcoma (ESS) may have sex cord differentiation, usually focal.Diagnosis of ESS is difficult when variant morphology predominates.Prognosis differs between ESS and UTROSCT; therefore, distinction is critical.Extensive tumor sampling is mandatory to identify neoplastic endometrial stroma.Sex cord differentiation may be associated with endometrial hyperplasia.

Real-time fluorescence polymerase chain reaction is a microbial identification method that can provide rapid and accurate results using a field-deployable thermocycler, the RAPID ("ruggedized" advanced pathogen identification device). A Yersinia pestis-specific TaqMan assay required approximately 75 minutes and achieved a sensitivity of 100 fg of Y. pestis genomic DNA (20 genome equivalents). Specificity testing against a genomic DNA cross-reaction panel comprised of 22 bacterial species encountered in the respiratory tract resulted in no false positives. No cross-reaction occurred with human genomic DNA.
