Summary

This case study highlights a rare subcutaneous liposarcoma on the chest wall. Initial diagnosis was lipoma, but surgical histology confirmed well-differentiated liposarcoma, emphasizing the need for careful follow-up.

Area of Science:

  • Oncology
  • Pathology
  • Radiology

Background:

  • Liposarcoma typically affects deep soft tissues, with rare occurrences in cutaneous or subcutaneous locations.
  • Subcutaneous liposarcomas present diagnostic challenges due to their infrequent presentation and potential for misdiagnosis as benign lipomas.

Observation:

  • A 63-year-old male presented with a large chest wall subcutaneous tumor.
  • Initial magnetic resonance imaging revealed a sizable subcutaneous mass.
  • An incisional biopsy initially suggested lipoma, showing mature adipose cells without lipoblasts.

Findings:

  • Surgical specimen histology revealed mature adipose cells alongside atypical cells with bizarre nuclei and lipoblasts.
  • The final diagnosis was well-differentiated liposarcoma, adipocytic (lipoma-like) type.

  • This highlights the importance of thorough histological examination for accurate liposarcoma diagnosis.

    • Implications:

    • Cutaneous and subcutaneous liposarcomas generally have a favorable prognosis.
    • Long-term surveillance is crucial due to the risk of local recurrence, high-grade transformation, and dedifferentiation.
    • Accurate diagnosis and vigilant follow-up are essential for managing these rare soft tissue tumors.
