Solitary fibrous tumor of the liver. Case report and review of the literature.

Solitary fibrous tumor (SFT) is a rare mesenchymal tumor. Given its origin, it can appear in almost any location. In the literature, only 50 cases of SFT in the liver parenchyma have been reported. Despite its rarity, this entity should be included in the differential diagnosis of liver masses. We report the first case with imaging data from five years prior to diagnosis, which was treated by right portal embolization and arterial tumor embolization, and subsequent liver resection. We also present an exhaustive review of the cases described to date.

Tumor fibroso solitario hepático. Descripción de un caso y revisión de la literatura / Solitary fibrous tumor of the liver. Case report and review of the literature

El tumor fibroso solitario (TFS) es una neoplasia mesenquimal infrecuente. Dado su origen, puede aparecer en prácticamente cualquier localización. En la literatura sólo hay 50 casos descritos de TFS localizado en el parénquima hepático. A pesar de su rareza, debe ser considerada dentro del diagnóstico diferencial de una masa hepática. Presentamos el primer caso con seguimiento por imagen desde 5 años antes del diagnóstico, tratado mediante embolización portal derecha y embolización arterial tumoral con posterior resección hepática, así como una revisión exhaustiva de los casos descritos hasta la actualidad

Sinupatia esfenoidal con extensión intracraneal causada por un hongo emergente / Sphenoid sinusitis with intracranial extension produced by an emergent fungus

Sinusitis fúngica esfenoidal en paciente diabética, con clínica inespecífica y signos de erosión ósea radiológica a nivel sellar superior y retroclival. Tratada quirúrgicamente por abordaje endoscópico transnasal y voriconazol oral. La histología mostró hifas, descartando invasión mucosa y el estudio molecular detectó ADN de Phialemonium curvatum, un inusual patógeno (AU)

This is a case of fungal sphenoid sinusitis in a diabetic patient with non-specific symptoms and bone erosion radiological findings in the superior and posterior sphenoid walls. Surgical treatment was performed by transnasal endoscopic approach and voriconazole orally thereafter.The histopathological study found fungus hyphal without mucosa invasion and the molecular study determined DNA to be Phialemonium curvatum, an unusual pathogen (AU)

Displasia mesenquimal placentaria / Placental mesenchymal dysplasia

La displasia mesenquimal placentaria (DMP) es una anomalía vascular que presenta una baja incidencia (0,02%) y se caracteriza por una placentomegalia con múltiples vesículas en grano de uva en el examen ecográfico. El diagnóstico diferencial principal es la mola hidatiforme parcial, pero la DMP coexiste con feto viable. Se asocia a crecimiento intauterino restringido (CIR), muerte fetal y, en el 30% de los casos, síndrome de Beckwith-Wiedemann. El diagnóstico de sospecha de la DMP es ecográfico, pero el diagnóstico definitivo lo dará el estudio anatomopatológico. Presentamos 2 casos de DMP, cuyo diagnóstico no se realizó hasta el análisis histológico, que cursaron con resultados perinatales diferentes, así como una revisión bibliográfica de la displasia mesenquimal placentaria (AU)

Placental mesenchymal dysplasia (PMD) is a vascular abnormality with a very low incidence (0.02%) that is characterized by placentomegaly with multiple grapelike vesicles on ultrasound examination. The main differential diagnosis of PMD is partial hydatidiform mole. However, in contrast to a partial mole, PMD can coexist with a viable fetus. PMD is associated with fetal growth restriction, fetal demise and Beckwith-Wiedemann syndrome in 30% of cases. The suspected diagnosis is based on ultrasound examination, but the final diagnosis of PMD is made by histological analysis. We present two cases of PMD which were diagnosed at necroscopy and which had distinct outcomes. A literature review of placental mesenchymal dysplasia is also provided (AU)
