Background & objectives: Melanoma is an aggressive malignancy known to widely metastasize to different sites. Metastases to mucosa are rare and such cases are often difficult to differentiate from primary melanomas or primary cancers of the corresponding organ.
Methods: Patient A., male, born 1945, was treated four times for cutaneous lesions (1996 – keratopapilloma, 1999 and 2004 – basal cell cancer, 2009 – trichoepithelioma). In 2010 a skin lesion clinically suspicious of melanoma was seen in the coronal region but after histological examination of the resected tumour sebaceous glands adenoma was diagnosed.
Results: In June 2011 the patient was admitted to oncourology department with macrohaematuria and bladder tumour was removed, histologically urothelial carcinoma grade III. In July 2012 right humerus bone metastasis was diagnosed. A subcutaneous lesion of the neck was found withmalignant cells suspicious ofmelanoma on cytological examination. In core needle biopsy in December 2012 from supraclavicular lymph node urothelial carcinoma was diagnosed. As clinical data (one and lymph node metastases, non-muscular invasive bladder cancer) and histological data were controversial, histologic preparations were re-evaluated. Solid clear cell tumour with brown pigment in some cells, positive for vimentin and S100, was seen in skin, bladder and neck lesions, consistent with melanoma.
Conclusion: The presented case shows that melanoma metastases to urinary bladder are very difficult to diagnose due to rarity of such lesions.
