[Skin tumours and primary multiple malignant neoplasms].

The structure of recurrent malignant neoplasms was analysed in a group of patients followed up on a permanent basis after the treatment for skin cancer. Observation of 2801 patients with primary basal and squamous cell skin cancer during 32 years (1975-2006) revealed 740 recurrent malignant neoplasms largely affecting skin, gastrointestinal tract, lungs, mammary and prostate glands.
