Resumen
La sarcoidosis de la médula ósea puede ocurrir incluso con radiografías normales del tórax. El diagnóstico requiere una biopsia de la médula ósea que muestre granulomas no casantes y la exclusión de la infección, con niveles elevados de la enzima de conversión de la angiotensina que apoyan los hallazgos.
Área de la Ciencia:
- Hematología Hematología.
- Pulmonología Pulmonología.
- Patología Patología Patología.
Sus antecedentes:
- La sarcoidosis es una enfermedad inflamatoria multisistémico caracterizado por granulomas no caseantes.
- La participación de la médula ósea en la sarcoidosis se diagnostica típicamente en pacientes con enfermedad conocida o imágenes torácicas anormales.
- La sarcoidosis aislada de la médula ósea sin manifestaciones pulmonares presenta un desafío diagnóstico.
Objetivo del estudio:
- Describir las características clínicas, histológicas y bioquímicas de la sarcoidosis limitada a la médula ósea.
- Para resaltar los criterios diagnósticos para la sarcoidosis de la médula ósea cuando las imágenes de tórax son normales.
- Evaluar la utilidad de los niveles de la enzima convertidora de angiotensina (ECA) en el diagnóstico de la sarcoidosis de la médula ósea.
Principales métodos:
- Análisis retrospectivo de cinco pacientes con sarcoidosis de médula ósea confirmada.
- Examen histopatológico de las biopsias de médula ósea para la detección de granulomas no caseantes.
- Exclusión de enfermedades infecciosas y otras enfermedades granulomatosas.
- Monitoreo en serie del estado clínico y los marcadores bioquímicos, incluidos los niveles de ECA.
Principales resultados:
- Cinco pacientes presentaron sarcoidosis de médula ósea a pesar de las radiografías torácicas normales.
- Las biopsias de médula ósea revelaron granulomas característicos no casados.
- Las enfermedades infecciosas fueron meticulosamente excluidas.
- Los niveles de la enzima convertidora de angiotensina estaban elevados en los cinco pacientes al momento del diagnóstico.
- El seguimiento varió de tres a seis años, confirmando el diagnóstico.
Conclusiones:
- La sarcoidosis de la médula ósea puede manifestarse sin una aparente afectación pulmonar.
- La histopatología de la biopsia de médula ósea es crucial para el diagnóstico.
- Los niveles elevados de la enzima convertidora de angiotensina en suero son un biomarcador valioso en la sospecha de sarcoidosis de la médula ósea.

Bone Marrow Sampling and Transplants
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...

Primary Lymphoid Organs
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

Secondary Lymphoid Organs
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Cardiomyopathy IV: Restrictive Cardiomyopathy
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
