[Giant-cell reparative granuloma (GCRG). A review of the literature, the present state of knowledge and therapeutic suggestions]. / Il granuloma riparativo a cellule giganti (GRCG). Review della letteratura, stati attuali delle conoscenze, suggerimenti terapeutici.

In the cranio-facial region the giant-cell reparative granuloma (GCRG) is a typical lesion of the maxillary bones. Because giant-cell reparative granuloma is not strictly a granuloma, clinically and histologically, many authors prefer call it giant-cell lesion (GCL). A review of the literature have along with our experiences is reported. Authors present 17 patients with giant-cell lesion and their results, treated at the Maxillo-Facial Department of Parma. Clinical, radiographic and pathologic features were evaluated and differential diagnosis was considered, showing the real great difficulty in differential diagnosis also and especially for surgical treatment.

Maxillary aspergillosis sinusitis more often occur in immunocompromised patients, but this pathology is increasing also in healthy people. Many risk factors are known and clinical and radiologic findings are aspecific; diagnosis therefore is possible with histologic and microbiologic aid. This particular disease and its surgical-pharmacological approach is explained.

The association between a so-called mucoepidermoid cyst and a central mucoepidermoid carcinoma in a 29-year-old man is reported. Since the two lesions are in continuity and the morphologic appearances are very much alike, a close relationship between these entities is suggested.
