Here anatomo-pathological preparations made dry in the late seventeenth century and presented neo-natal malformations made with formalin are exposed. Alterations of the skeleton and blood vessels are shown, as well as diseases traces that have now disappeared, such as syphilis. The skulls of fetuses and children show malformations such as macrocephaly. In the room there is also a collection of liver, kidney and bladder stones of patients hospitalized at the Holy Spirit Hospital in the nineteenth century. It is possible to see the skull of Pliny the Elder, found at the mouth of the Sarno at the beginning of 900.
