We present three cases of benign SLN that were clinically suspicious for involvement by metastatic melanoma and where found to be involved with other diseases or deposits previously unknown, A 44-year-old woman presented with a 1.6 cm pigmented lesion on her back.

An excisional skin biopsy revealed a 1.7-mm-thick superficial spreading melanoma. The patient had bilateral silicone breast prostheses. An axillary sentinel lymph node (SLN) excision was performed. The lymph node examination showed a granulomatous reaction, with numerous macrophages.

There was no evidence of metastatic melanoma by immunohistochemical studies with S-100, Melan-A, and HMB-45.
