Two small areas of gray discoloration were also seen on the palatal gingiva. The provisional diagnosis was postinflammatory pigmentation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Following excision of all lesions, an oral mucosal melanoma in situ was diagnosed. A watch\u2010and\u2010wait approach with a 3\u2010month follow\u2010up was decided. Twelve months later, the lesion recurred in the subpontic area, and wide excision on clinically normal margins of the gingival mucosa to the level of periosteum was performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This case emphasizes that peri\u2010implant pigmentation should not automatically be attributed to inflammatory or implant\u2010related causes.
