MRI of a benign chondroid syringoma.

Chondroid syringoma, also known as mixed tumour of the skin, is a relatively rare, usually benign tumour. A few malignant cases, especially in the lower extremities, have been published, but most of them behave in a benign fashion. A case of a middle-aged woman with surgically proved chondroid syringoma in the pretibial region is presented in this report with MRI and histological findings. Despite rapid growth over a short period of time and a location reportedly associated with malignancy, the histological features were benign.

Spurious stones.

One hundred and sixteen (3.5%) of 3,300 specimens submitted by 72 patients as urinary stones were artifacts, i.e. not formed of accepted constituents of urinary calculi. The laboratory diagnostic methods included infrared and wet chemical analysis, and X-ray diffraction. Twenty-eight were of organic origin and some of these were undoubtedly submitted by accident as calculi. Eighty-eight were of mineral origin, mainly quartz and feldspar, and it is believed that the great majority were submitted for secondary gain or for psychiatric reasons. Ten patients each submitted from 2 to 10 artifacts. Five cases studies are presented which illustrate some confounding clinical and laboratory findings. Spurious stones can lead to difficult clinical and laboratory problems.
