Summary

This study describes two jaw non-Hodgkin's lymphoma cases with a sarcomatoid pattern originating in bone. Diagnosis can be challenging due to resemblance to inflammatory conditions, highlighting the need for advanced diagnostic methods.

Area of Science:

  • Oral Pathology
  • Hematopathology
  • Oncology

Background:

  • Non-Hodgkin's lymphoma can rarely present with sarcomatoid features.
  • Jaw bone involvement by lymphoma is uncommon.
  • Distinguishing sarcomatoid lymphoma from other bone neoplasms is critical for appropriate management.

Observation:

  • Two cases of jaw non-Hodgkin's lymphoma exhibiting a sarcomatoid pattern are presented.
  • Radiologic studies confirmed primary bone origin.
  • Histologic examination revealed intense stromal sclerosis and atypical cells with high mitotic activity.

Findings:

  • The tumors infiltrated mandibular bone and adjacent soft tissues.
  • Immunohistochemical and ultrastructural studies confirmed the lymphoid origin of these sarcomatoid neoplasms.

  • One case experienced diagnostic delay due to clinical similarity to inflammatory periodontal disease.

    • Implications:

    • Highlights the importance of considering sarcomatoid lymphoma in the differential diagnosis of jaw bone lesions.
    • Emphasizes the utility of immunohistochemistry and ultrastructural analysis for definitive diagnosis.
    • Suggests potential challenges in early clinical diagnosis of these rare entities.
