Resumen
La neoplasia pseudopapillar sólida (SPN), o tumor de Frantz, es un raro tumor pancreático a menudo diagnosticado erróneamente como un pseudocisto. La histopatología es crucial para el diagnóstico preciso y el tratamiento quirúrgico exitoso en mujeres jóvenes.
Área de la Ciencia:
- Oncología Oncología.
- Gastroenterología y Gastroenterología.
- Patología Patología Patología.
Sus antecedentes:
- La neoplasia pseudopapiliar sólida (SPN), también conocida como tumor de Frantz, es una rara neoplasia pancreática.
- SPN afecta predominantemente a mujeres jóvenes y tiene un bajo potencial maligno.
- Distinguir SPN de otras lesiones pancreáticas quísticas, como los pseudocistos, plantea un desafío diagnóstico debido a presentaciones clínicas inespecíficas.
Objetivo del estudio:
- Para informar de un caso de tumor de Frantz inicialmente diagnosticado erróneamente como un pseudocisto pancreático infectado.
- Para resaltar las dificultades de diagnóstico en la diferenciación de las lesiones pancreáticas quísticas.
- Para enfatizar la importancia de la confirmación histopatológica para el manejo de SPN.
Principales métodos:
- Informe de caso de una mujer de 31 años con dolor abdominal.
- Diagnóstico inicial y tratamiento para el pseudocisto pancreático infectado.
- Examen histopatológico posterior de la muestra quirúrgica para el diagnóstico definitivo.
Principales resultados:
- La presentación inicial del paciente imitaba un pseudocisto infectado con colección de fluidos y focos de gas.
- La histopatología confirmó la presencia de un tumor de Frantz (SPN).
- El paciente se sometió a una exitosa pancreatoduodenectomía con intención curativa.
Conclusiones:
- El tumor de Frantz (SPN) debe considerarse en el diagnóstico diferencial de lesiones pancreáticas quísticas en mujeres jóvenes, incluso con signos iniciales de infección.
- La degeneración quística y hemorrágica en SPN puede imitar otras patologías pancreáticas.
- La resección quirúrgica completa basada en el diagnóstico histopatológico ofrece un excelente pronóstico para el SPN.

20.9K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

02:22Structures of Solids
18.2K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

16.2K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

02:54Molecular and Ionic Solids
20.2K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...
