Caracterização das fases de desenvolvimento de células gigantes induzidas por Meloidogyne exigua em raiz de seringueira (Hevea brasiliensis Muell. Arg.)

The developmental phases of giant cells induced by root-knot nematodes (Meloidogyne exigua) in rubber plant (Hevea brasiliensis) root were studied in relation to its number and size evaluated in eight sample dates. The results were subject to cluster analysis and principal component analysis. Sample dates were clearly distinct regarding giant cell development. As a result, the nematode infestation cycle was characterized by the following sequential phases: initial, equilibrium, choice and final.

Granuloma periférico de células gigantes: relato de caso

The peripheral giant cell granuloma (GPCG) is defined as a benign disorder of uncertain etiopathogenesis and proliferative reaction of the fibrous connective tissue or periosteum, which is characterized histologically by the presence of multinucleated giant cells. The purpose of this study is to report a case of GPCG in a 56-year-old white woman presenting a bleeding nodule on palpation, a red color with small whitish ulcerated areas, defined limits, resilient consistency, a pedicled base 2.0 cm in diameter, asymptomatic, involving the permanent lower left third molar, which presented mobility. Radiographically there was significant bone loss in this tooth region, whose initial diagnosis was pyogenic granuloma. The definitive diagnosis was obtained after excisional biopsy the microscopic examination of which identified the presence of multinucleated giant cells. The clinical postoperative follow-up revealed a favorable cicatricial repair of the operated area with no recurrence after 9 months of monitoring.

The peripheral giant cell granuloma (GPCG) is defined as a benign disorder of uncertain etiopathogenesis, and proliferative reaction of the fibrous connective tissue or the periosteum, which is characterized histologically by the presence of multinucleated giant cells. The purpose of this study is report a case of GPCG in a white women, with 56 years old, presenting nodule bleeding to the touch, red and white with small ulcerated areas, defined limits, resilient consistency, pedicled base with 2.0 cm diameter, asymptomatic, involving the permanent lower left third molar, that it was presented with mobility. Radiographically there was significant bone loss in this tooth region, whose initial diagnosis was pyogenic granuloma. The definitive diagnosis was obtained after excisional biopsy in which microscopic examination it was identified e presence of multinucleated giant cells. The clinical postoperative presented favorable cicatricial repairing of the operated area without recurrence after two years of monitoring.
