The article presents a case study of a 82-year-old Japanese female with a granulomatous nodule on the nail of the third digit of her right foot. Her histopathological examination of a biopsy specimen from the granulomatous nodule showed a proliferation of tumour cells into the deep dermis. She was undergone for sentinel lymph node (SLN) biopsy and amputation and diagnosed with subungual melanoma.
