Some sarcomas are often misdiagnosed as benign tumors due to their bland appearance and slow growth. Accurate diagnosis is crucial as these sarcomas can progress locally, requiring proper treatment.

Area of Science:

  • Soft tissue pathology
  • Oncology
  • Surgical pathology

Background:

  • Benign mesenchymal neoplasms and reactive proliferations can mimic sarcomas.
  • Certain low-grade sarcomas are frequently misidentified as benign lesions.

Purpose of the Study:

  • To review five soft tissue lesions that are often underrecognized as sarcomas.
  • To discuss the clinicopathologic features and differential diagnosis of these challenging neoplasms.

Main Methods:

  • Review of literature on selected soft tissue sarcomas.
  • Analysis of clinicopathologic features contributing to misdiagnosis.

Main Results:

  • Five specific soft tissue lesions are highlighted: low-grade fibromyxoid sarcoma, low-grade myxofibrosarcoma, well-differentiated liposarcoma, epithelioid sarcoma, and inflammatory fibrosarcoma.

  • Underrecognition is attributed to bland cytology, hypocellularity, and indolent clinical course.
  • These lesions can exhibit histological progression in local recurrences.

    • Conclusions:

    • Accurate diagnosis of these underrecognized sarcomas is essential for appropriate management.
    • Understanding the potential for progression in recurrent lesions is critical.
    • This review aims to improve the recognition of these "treacherous" neoplasms.
