From the Guidelines

El próximo paso en el manejo de un paciente asintomático con una tomografía computarizada (TC) de cabeza que muestra linfoma en la región subcutánea occipital es realizar una biopsia de tejido para diagnóstico y clasificación definitiva del linfoma, seguido de una evaluación de estadificación completa. Esto se debe a que la clasificación del linfoma impacta directamente en la selección del tratamiento y el pronóstico, y una estadificación adecuada garantiza la intensidad y duración adecuadas de la terapia 1.

Algunos puntos clave a considerar en el manejo de este paciente incluyen:

  • La biopsia de tejido es crucial para determinar el subtipo de linfoma y guiar el tratamiento posterior.
  • La evaluación de estadificación debe incluir pruebas como recuento sanguíneo completo, panel metabólico completo, nivel de lactato deshidrogenasa (LDH), biopsia de médula ósea y PET/TC para determinar la extensión de la enfermedad.
  • Después de la biopsia y la estadificación, el paciente debe ser remitido a un hematóncologo para planificar el tratamiento, que puede incluir quimioterapia, radioterapia o una combinación de ambas, dependiendo del subtipo de linfoma, la etapa y los factores del paciente.
  • La guía de la British Association of Dermatologists y el UK Cutaneous Lymphoma Group recomienda que los pacientes con linfoma cutáneo primario difuso grande B-cell (no especificado) con lesiones solitarias deben ser tratados con la intención de cura, y que la radioterapia es el tratamiento preferido para reducir el riesgo de recaída local 1.

Es importante tener en cuenta que, aunque el paciente es asintomático, el linfoma es una enfermedad sistémica que requiere una evaluación y tratamiento oportunos para prevenir la progresión y mejorar los resultados. La monitorización activa es una opción para pacientes con enfermedad asintomática, pero se debe considerar el tratamiento con radioterapia o quimioterapia según la etapa y el subtipo de linfoma 1.

Next Steps in Management

For an asymptomatic patient with a computed tomography (CT) scan of the head showing lymphoma in the subcutaneous occipital region, the following steps can be considered:

  • Biopsy for Diagnosis: A biopsy is essential for confirming the diagnosis of lymphoma. Given the location of the lymphoma in the subcutaneous occipital region, a superficial lymph node biopsy may be considered, as suggested by 2, which can provide diagnostic information with minimal risk.
  • Choice of Biopsy Method: The choice between surgical excisional biopsy and core needle biopsy should be considered. While surgical excisional biopsy is the standard of care, core needle biopsy has been shown to be a viable alternative, offering a less invasive approach with comparable diagnostic yield, as indicated by 3.
  • Subclassification of Lymphoma: Subclassification of lymphoma is crucial for determining the appropriate treatment. However, subclassification may be challenging, especially in low-grade non-Hodgkin lymphoma and Hodgkin lymphoma, as noted by 4.
  • Consideration of Patient Factors: Patient factors, such as age and underlying medical conditions, should be taken into account when deciding on the biopsy method. For example, core needle biopsy may be preferred in older patients or those with significant comorbidities, as suggested by 3.
  • Importance of Follow-up: Continued follow-up with repeat biopsy may be necessary, especially if the initial biopsy is inconclusive or if the patient's condition changes, as illustrated by the case presented in 5.
  • Diagnostic Approaches: Other diagnostic approaches, such as EUS-guided biopsy, may be considered in certain cases, although their yield may vary depending on the type of lymphoma, as reported by 4.

Key Considerations

  • The diagnostic approach should be individualized based on the patient's specific circumstances and the characteristics of the lymphoma.
  • A multidisciplinary team, including hematologists, radiologists, and pathologists, should be involved in the diagnosis and management of the patient.
  • The patient's preferences and values should be taken into account when making decisions about the diagnostic approach and treatment plan, as supported by 2, 3.
