Young man with acromegaly and asymmetric features

There are only mild facial features of acromegaly at this point in the man's illness but marked asymmetric involvement of the arms, with the left arm and hand markedly larger than the left. The left index finger has also grown in deformed manner. This is one of a series of five photographs of cases of acromegaly described by German pathologist Rudolf Virchow (1821-1902) in a paper that was read before the Berlin Medical Society on January 16, 1889.
