title: Malignant histiocytoma in talus: diagnostic problems.
abstract: A malignant histiocytoma of the left talus is described. The patient was introduced to our hospital because of an infected recidivation of a partly exstirpated tumor. It is classified as a metastasis of a malignant melanoma. The final histologic diagnosis could be proved by the original slides. The exarticulation of the knee was followed by chemotherapy.
