Giant-cell tumour of the tendon sheath--an uncommon tumour presenting to dermatologists.

We describe a patient who presented with two skin-coloured, non-mobile, soft dermal nodules on the tip of the distal phalanx of the left middle finger. Skin biopsy revealed the features of a giant-cell tumour of the tendon sheath. This benign tumour is one of the most common tumours affecting the hand but is, we believe, infrequently encountered by dermatologists and rarely mentioned in the dermatological literature.
