Sildenafil

Sildenafil Reactions 1704, p341 - 2 Jun 2018 Melanoma: 2 case reports In a case report, a 46-year-old man and an 48-year-old man were described, who developed melanoma following treatment with sildenafil [Viagra; doses, routes, indications, durations of treatments to reactions onsets and outcomes not stated]. Case 1: A 46-year-old man developed a > 5mm lesion on his upper back. Biopsy revealed a superficial spreading melanoma showing four mitoses per square mm of tumour. The tumour was in close association with significantly dilated thin-walled blood vessels. Another dilated vessel was massively involved by tumour. The lesion was positive for immunostains Melan A (Mart 1), HMB45 and Ki67. He reported weekly use of sildenafil for seven years. Case 2: A 48-year-old man developed a 7.5 mm lesion on his lower back. Biopsy showed superficial spreading melanoma six mitoses per square mm of tumour. The tumour was adjacent to a massively dilated thin-walled blood vessel and another dilated vein heavily involved by tumour. The lesion was moderately positive for immunostains Melan A (Mart 1), HMB45 and Ki67. He reported use of sildenafil weekly or twice weekly for two years.
