Malignant melanoma is a malignant tumor with increasing prevalence worldwide. However, metastatic malignant melanoma with unknown primary origin is rarely seen. The current study presents a case with bilaterally multiple nodules in pulmonary parenchyma in which no primary malignant site was found, despite detailed screening and diagnosed as metastasis of malignant melanoma by surgical lung biopsy. The current case is presented as a reminder that malignant melanoma should be kept in mind in metastatic lung lesions with unknown primary origin.

Keywords: Malignant melanoma, unknown primary origin, lung, metastasis, pulmonary nodules

Malign melanom, tüm dünyada prevalansý giderek artan bir malign tümördür. Bununla birlikte, primeri bilinmeyen metastatik malign melanom olgularý nadir görülmektedir. Biz de bilateral akciðer parankiminde multipl nodülleri olan ve yapýlan tarama tetkiklerinde primer odak saptanamayan ancak açýk akciðer biyopsi sonucunda malign melanom metastazý tanýsý konulan olgumuzu sunmaktayýz. Bu olgu, primeri bilinmeyen akciðer metastazý olgularýnda malign melanomun da akýlda tutulmasý gerektiðini hatýrlatmak amacýyla sunulmuþtur.

Anahtar Kelimeler: Malign melanom, primeri bilinmeyen, akciðer, metastaz, pulmoner nodül
