Abstract

The  results  of  clinical,  radiological  (digital  X-ray,  CT,  MSCT)  lung  examinations, 5-10 years follow-up in 288 patients were analyzed. Disseminated cutaneous melanoma   was   diagnosed   in   139   of   288  patients  (48.3%).  In  84  of  these 139 patients (60.4%) lung metastases were detected. The sensitivity of digital X-ray in the detection of solitary and multiple lung metastases with diameter >0.5 cm was 87.5% and 100.0% respectively. CT and MSCT were superior to digital X-ray in the detection of metastases with diameter <0.5 cm. The order of tumor spread to regional lymphatic nodes, lungs and other visceral organs was defined. In 77.8 % of cases the maximal duration of pulmonary phase of dissemination during complex treatment was 6 months.

Key words
Melanoma, metastases, digital X-ray, spread.
