ABSTRACT
Accurate characterization of tropical moist forest changes is needed to support conservation policies and to quantify their contribution to global carbon fluxes more effectively. We document, at pantropical scale, the extent and changes (degradation, deforestation, and recovery) of these forests over the past three decades. We estimate that 17% of tropical moist forests have disappeared since 1990 with a remaining area of 1071 million hectares in 2019, from which 10% are degraded. Our study underlines the importance of the degradation process in these ecosystems, in particular, as a precursor of deforestation, and in the recent increase in tropical moist forest disturbances (natural and anthropogenic degradation or deforestation). Without a reduction of the present disturbance rates, undisturbed forests will disappear entirely in large tropical humid regions by 2050. Our study suggests that reinforcing actions are needed to prevent the initial degradation that leads to forest clearance in 45% of the cases.
ABSTRACT
Primary lymphomas of the bone or skeletal muscle are rare. Three mechanisms of lymphomatous involvement of the muscle have been described, namely direct invasion from adjacent involved lymph nodes or bone, metastatic spread and, least commonly, primary muscle lymphoma. We herein present a rare case of primary mucle non-Hodgkin lymphoma with a description if the associated clinicopathological findings and a review of the relevant literature. A 41-year-old female patient was referred to our hospital with a painful mass in the right lower extremity. Following resection and histopathological examination, a diffuse large B-cell lymphoma originating from the muscle with cutaneous and subcutanenous infiltration was diagnosed. The patient received chemotherapy with six cycles of cyclophosphamide, hydroxydaunomycin, oncovin and prednisone (CHOP regimen) and a complete radiological response was achieved after six cycles of treatment.
