[Metastases of malignant melanoma of unknown primary site: an important diagnostic and therapeutic problem]. / Przerzuty czerniaka zlosliwego o nieznanej lokalizacji ogniska pierwotnego--istotny problem diagnostyczny i terapeutyczny.

ABSTRACT

Malignant melanoma of an unknown primary site remains a diagnostic and therapeutic challenge in clinical practice. With this in mind, we have presented 12 patients with malignant melanoma of an unknown primary site, diagnosed and treated in the Regional Cancer Center in Bialystok. This clinical presentation accounted for 2% of all malignant melanocytic lesions treated in our center during ten year period from 1987 to 1997.
