Adult granulosa cell tumor (AGCT) and sex cord tumor with annular tubules (SCTAT) are distinct sex cord stromal tumors with different molecular signatures. We present a unique case of an incidental ovarian tumor with mixed AGCT and SCTAT morphologic patterns. Due to the unusual co-occurrence, molecular testing was separately performed on both components. Despite minimal overlap in morphology, both the SCTAT and AGCT components were found to have an identical mutation profile, including the prototypical FOXL2 p.C134W mutation characteristic of AGCT. We thus present the first report of AGCT with SCTAT-like pattern.

Cirl buntings in the UK were translocated over a 5‐year period by collecting chicks from the residual population, hand‐rearing and releasing them at a site in Cornwall with the aim of establishing a second breeding population. Because mortality and morbidity during captivity restrict the number and fitness of individuals available for release, selected parasites were monitored in the captive chicks, and all deaths were investigated by autopsy, histopathology and bacteriology. Risk factors associated with captive deaths were analysed. Annual mortality during captivity ranged from 4% (3 of 75 chicks in 2006) to 42% (26 of 73 in 2007) of chicks collected. Infectious disease associated with immunosuppression was an important factor in many deaths, and chicks collected with lower body weight were at greater risk of mortality. These findings emphasise the need for rigorous monitoring of all aspects of captive care during passerine translocations and provide evidence‐based recommendations for future projects.
