Definition / general
- May cause lymphadenopathy, usually resolves spontaneously
- Pigment initially within keratinocytes, fibroblasts, macrophages and mast cells; later only within dermal fibroblasts surrounded by connective tissue; eventually tattoo ink appears in regional lymph nodes
- Melanoma patients should be questioned regarding history of tattoos, particularly prior to sentinel node treatment (Int Semin Surg Oncol 2005;2:28)
- Histologic confirmation of melanoma in nodes is necessary to avoid unnecessary surgery (Dermatol Surg 1996;22:92)
