Resumen
La fasceítis nodular (FN), una afección mamaria benigna, puede imitar el cáncer debido a su rápido crecimiento. El diagnóstico temprano mediante biopsia y la positividad de ASMA son cruciales para un manejo preciso y para evitar tratamientos innecesarios.
Área de la Ciencia:
- Oncología; Patología; Radiología
Sus antecedentes:
- La fasceítis nodular (FN) es un raro tumor miofibroblástico benigno.; La FN de la mama es excepcionalmente infrecuente y presenta desafíos diagnósticos.; El rápido crecimiento puede llevar a una mala interpretación como malignidad.
Objetivo del estudio:
- Presentar un caso de fasceítis nodular mamaria en una mujer joven.; Destacar los desafíos diagnósticos y la importancia del diagnóstico diferencial.; Enfatizar la evaluación histopatológica precisa para un manejo adecuado.
Principales métodos:
- Informe de caso de una mujer joven con una masa mamaria en rápida expansión.; Se utilizó el sistema de informes y bases de datos de imágenes mamarias (BIRADS).; Se realizó biopsia con aguja gruesa y evaluación histopatológica, incluida la tinción con actina de músculo liso alfa (ASMA).; Se completó con biopsia escisional para el tratamiento definitivo.
Principales resultados:
- La masa mamaria fue inicialmente BIRADS-III, progresando a BIRADS-IVA.; La biopsia con aguja gruesa reveló un neoplasma de células fusiformes.; La histopatología confirmó fasceítis nodular con positividad para ASMA.; La biopsia escisional resultó en una resolución completa.
Conclusiones:
- La fasceítis nodular debe considerarse en el diagnóstico diferencial de las lesiones mamarias de células fusiformes.; La evaluación histopatológica precisa es vital para prevenir el diagnóstico erróneo.; El diagnóstico temprano y correcto evita intervenciones agresivas innecesarias para afecciones mamarias benignas.

The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...

Layers of Connective Tissue Proper

Fascia, a thin layer of fibrous connective tissue, is distributed throughout the body. It demarcates and forms a supportive covering over skeletal muscles, bones, blood vessels, and organs. There are three main types of facia— superficial fascia, deep fascia, and subserous fascia. These are all present at different depths in the body. Fascia reduces the friction and permits muscles, joints, and organs to easily slide against each other, facilitating movement of the body and preventing...

Disorders of the Female Reproductive System

The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...
