  • Look Inside

 A patient with malignant melanoma in the nasal cavity was treated by BCG immunotherapy with subsequent surgery. The direct injection of BCG solution into the melanoma tissue resulted in a marked regression of the tumor within 40 days, however the tumor began to grow 3 months later and filled the nasal cavity in the next 2 months.

 Histology of the tumor on the 10th day after the initiation of BCG therapy showed noticeable infiltration of monocytes and necrosis of the tumor. Ultrastructural findings disclosed that the fusion of melanoma cells and monocytes, and phagocytic action of monocytes. It was concluded that malignant melanoma should first be treated by BCG immunotherapy before surgical treatment.
