title: An unusual testicular lump.
abstract: A 32-year-old British Asian man presented with what appeared clinically and on ultrasound to be a testicular tumour. However, syphilis serology, histology and detection of Treponema pallidum DNA by polymerase chain reaction confirmed that the lesion was a gumma. Without routine syphilis serology, the correct diagnosis may have been missed.
