This medical monograph, La tubercolosi extrapolmonare, in two volumes by Mario Donati, published in 1936, offers a comprehensive clinical and pathological study of extrapulmonary tuberculosis. Addressing forms of tuberculosis affecting organs and systems outside the lungs, the work reflects early 20th-century medical knowledge and surgical practices. It combines descriptive pathology, clinical signs, diagnostic methods, and therapeutic approaches as applied to bones, lymph nodes, the urogenital system, and the central nervous system. Rich in clinical cases and written in a scholarly yet accessible format, it was a significant reference for physicians and surgeons of its time.
