    Epithelioid sarcoma is a rare skin tumor that presents diagnostic challenges. Histological and ultrastructural analysis aids in distinguishing it from other skin lesions and understanding its varied progression.

    Area of Science:

    • Dermatopathology
    • Oncology
    • Surgical Pathology

    Background:

    • Epithelioid sarcoma is a rare soft tissue sarcoma.
    • It often presents as a nodular skin lesion, leading to diagnostic confusion.
    • Understanding its unique histological and ultrastructural features is crucial for accurate diagnosis.

    Observation:

    • Review of twelve epithelioid sarcoma cases.
    • Analysis of diagnostic challenges and varied tumor progression rates.
    • Comparison with benign nodular skin lesions like rheumatoid nodule and granuloma annulare.

    Findings:

    • Specific histological features help differentiate epithelioid sarcoma from other skin lesions.
    • Ultrastructural examination of two cases revealed resemblance to immature mesenchymal tissue.
