Hermann Schloffer

Hermann Schloffer (May 13, 1868 – January 21, 1937) was an Austrian surgeon who was a native of Graz

He studied medicine at the Universities of Freiburg and Graz, where in 1892 he earned his medical doctorate. He spent several years in Prague as a surgical assistant and associate professor, and from 1903 to 1911 was a surgeon and professor at the University of Innsbruck. Afterwards he was a professor at Charles University in Prague.

In March 1907, Schloffer performed the first transsphenoidal surgery for removal of a pituitary adenoma. Unfortunately, the patient died several weeks afterwards from a residual tumor. His name is lent to the eponymous "Schloffer tumor", described as an uncommon pseudo-tumor of the abdominal wall that usually appears several years after abdominal surgery.

In 1916, Schloffer became the first to remove a spleen for idiopathic thrombocytopenic purpura (ITP). His student Paul Kaznelson (1898-1959) hypothesized - in analogy with hemolytic anemia - that the excessive destruction of platelets in ITP would occur in the spleen and suggested to his tutor Schloffer to perform a splenectomy on a patient with chronic ITP. Schloffer followed Kaznelson's suggestion. Their first patient so treated showed a dramatic improvement.[1]
