All of the soft tissue around the implant was removed until the periosteum was reached. Histologic examination of the lamina propria revealed a cellular proliferation with imprecise boundaries, dense stromal component composed of spindle- to round-shaped mononucleated cells (fibroblasts and monocytes\/macrophages), abundant multinucleated giant cells surrounding microscopic hemorrhagic foci, and deposits of hemosiderin; the diagnosis was peripheral giant-cell reparative granuloma (PGCG). Giant cells share the immunohistochemical expression of monocyte\/macrophage markers (CD68, calprotectin [Mc387]) and osteoclastic cell markers (tartrate-resistant acid phosphatase, cathepsin K, and microphthalmia-associated transcription factor). After 6 months of follow-up, no bone resorption or recurrence of implant loss was observed. There have been only 12 case reports on dental implant\u2013associated PGCG. Research results to date indicate that there may be little difference in immunophenotype among the giant cells of PGCG, central giant cell reparative granuloma, and peri-implant osteolysis. In conclusion, the immunohistochemical study confirms an osteoclast like giant cells phenotype differentiation in PGCG.<\/jats:p>","DOI":"10.1563\/aaid-joi-d-13-00155","type":"journal-article","created":{"date-parts":[[2013,9,23]],"date-time":"2013-09-23T14:33:03Z","timestamp":1379946783000},"page":"55-60","source":"Crossref","is-referenced-by-count":12,"title":["Immunophenotype of Dental Implant-Associated Peripheral Giant Cell Reparative Granuloma in a Representative Case Report"],"prefix":"10.1563","volume":"42","author":[{"given":"Pablo","family":"Galindo-Moreno","sequence":"first","affiliation":[{"name":"Oral Surgery and Implant Dentistry Department, School of Dentistry, University of Granada, Spain."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pedro","family":"Hern\u00e1ndez-Cort\u00e9s","sequence":"additional","affiliation":[{"name":"Department of Traumatology and Orthopedic Surgery, San Cecilio Clinical Hospital, University of Granada, Spain."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rosa","family":"R\u00edos","sequence":"additional","affiliation":[{"name":"Pathology Department, San Cecilio Clinical Hospital, University of Granada University of Granada, Spain."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elena","family":"S\u00e1nchez-Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Oral Surgery and Implant Dentistry Department, School of Dentistry, University of Granada, Spain."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miguel","family":"C\u00e1mara","sequence":"additional","affiliation":[{"name":"Pathology Department, San Cecilio Clinical Hospital, University of Granada University of Granada, Spain."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco","family":"O'Valle","sequence":"additional","affiliation":[{"name":"Pathology Department, School of Medicine, and IBIMER, University of Granada, Spain."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"434","reference":[{"key":"i1548-1336-42-1-55-b01","series-title":"Oral Surg Oral Med Oral Pathol","first-page":"159","article-title":"Giant-cell reparative granuloma, traumatic bone cyst, and fibrous (fibrosseous) dysplasia of the jawbones","volume":"6","author":"Jaffe\n HL.","year":"1953","unstructured":"Jaffe\n HL.\n \n \n Giant-cell reparative granuloma, traumatic bone cyst, and fibrous (fibrosseous) dysplasia of the jawbones.
