Histopathological examination following radical nephrectomy with tumor thrombectomy demonstrated a pathological complete response. Diffuse programmed death-ligand 1 expression on pretreatment biopsy may have been associated with a favorable response to nivolumab plus ipilimumab.
No disease progression was observed at 9 months. This case demonstrates the potential efficacy of combination immunotherapy in aggressive metastatic MTSCC.
The tumor burden was small without metastasis. This case highlights that ICI hepatitis can progress with minimal aminotransferase elevation in advanced cirrhosis, warranting multidimensional monitoring beyond aspartate aminotransferase/alanine aminotransferase, including bilirubin, coagulation parameters, clinical decompensation, and quantitative imaging.

Despite 4 cycles of ipilimumab/nivolumab immunotherapy, the disease progressed, and the patient died 4 months after diagnosis. BNM is a rare melanoma variant, often arising from a pre-existing blue nevus, with aggressive potential and frequent lymph node metastasis. The molecular heterogeneity of BNM and the limited therapeutic options underscore the need for further research into targeted therapies and prognostic biomarkers for this rare melanoma subtype.
