Sinus histiocytosis with massive lymphadenopathy known as Rosai-Dorfman disease is characterized by painless bilateral cervical lymphadenopathy. Extranodal manifestations are uncommon and spinal involvement is rare. A 15-year-old man presented with intermittent midthoracic back pain only. He had no specific findings on neurologic examinations, hematologic and biochemical laboratory tests. Radiological examination of thoracic spine revealed collapse of T6 vertebrae with thoracic kyphosis and osteolytic lesion of T12 vertebra body. He underwent a removal of bone tumor, anterior reconstruction with mesh and pedicle screw fixation via posterior approach for pathologic confirmation and stabilization. Histopathologic study of the lesion revealed focal infiltration of large histiocytes showing emperipolesis. Immunochemistry stain of histiocytes was positive for CD68 and S-100 but negative for CD1a. This report presents a rare case and literature review of extranodal Rosai-dorfman disease in thoracic spine.

OBJECTIVE: The aim of our study was to compare the thickness and histopathologic changes in the fetal membrane between premature rupture of membranes (PROM) and intact membrane after delivery. METHODS: In a prospective study involving 31 patients who were divided into 4 groups such as <37 weeks without PROM, <37 weeks with PROM, >or=37 weeks without PROM, and >or=37 weeks with PROM, we measured the thickness of membrane and studied the histopathologic findings in vitro by light microscopy of histological sections. RESULTS: The membrane thickness of <37 weeks with PROM group was thinner (35.9 micrometer) than that (42.3 micrometer) of <37 weeks without PROM group, but there was no statistical significance. The membrane thickness of >or=37 weeks with PROM and >or=37 weeks without PROM were similar (25.6 micrometer, 26.0 micrometer). But the membrane thickness of >or=37 weeks with/without PROM was significantly thinner (25.8 micrometer) compared with that (38.9 micrometer) of <37 weeks with/without PROM. The histopathologic features of PROM positive group was amnionitis with neutrophilic infiltration, focally or diffusely necrotic change of amniotic membrane, separation of amniotic membrane and degeneration of chorionic villi. CONCLUSION: The thickness of fetal membrane between PROM group and intact membrane group was not different but the thickness of fetal membrane between <37 weeks and >or=37 weeks was statistically significant. The histopathologic change of PROM positive group was prominent as amnionitis. Further evaluation will be needed about the relationship between membrane thickness and PROM.

PURPOSE: To report two cases of submacular hemorrhage worsened after intravitreal gas (sulfuric hexafluoride; SF6) injection without tissue plasminogen activator. METHODS: Two old men complaining of decreased visual acuity in their one eye visited clinic. On ocular examination, both of them had subretinal hemorrhage in macular area choroidal neovascularization on fluorescein angiography. 0.5cc sulfuric hexafluoride (SF6) gas was injected into vitreous cavity and patients were educated to keep strict prone position. Several days after intravitreal injection, visual acuity decreased and subretinal hemorrhage increased and spread to adjacent area. RESULTS: In cases of the intravitreal injection, aggravation of subretinal hemorrhage should be considered, even without tPA and if so, it is necessary to monitor and informed the patients in detail.
