Preziossisimo Sangue di Nostro Signore Gesù Cristo ad Appio Latino is at Via Beata Maria De Mattias 10, by the Largo Pannonia in the Appio Latino quarter, just off the Via Gallia near the Porta Metronia.
It is the convent chapel of the Generalate of the Congregation of Sisters, Adorers of the Precious Blood. Pictures of the church at Wikimedia Commons. 
It was completed in 1937, and looks like a design by Tullio Rossi in his typical neo-Romanesque style. It is in puce-coloured brick, with a nave and aisles and a rectangular apse. There are two little semi-circular side chapels off each aisle. The blank gabled façade is false, as the pitch of the nave roofline is continued to conceal the aisles. There is a porch with three entrance arches in stone, and above this is a round window framing a Greek cross. There is no other decoration.
The interior is in unplastered brick, with an unpainted coffered wooden ceiling. The nave arcade pillars are square with chamfers and odd-looking capitals formed from four rhomboidal stones each giving the effect of a crown. The otherwise blank wall above the altar is dominated by a large mosaic of the Crucifixion in an Impressionistic style reminiscent of Picasso. The stained glass in the nave windows representing the Instruments of the Passion is by Nocchi, and in one of the chapels is enshrined Bl Mary de Mattias, the foundress of the congregation.
