Appendiceal Elastofibroma Requiring Ileocecectomy.

Area of Science:

• Gastroenterology
• Pathology
• Surgical Oncology

Background:

• Elastofibromas are uncommon benign soft tissue tumors.
• Characterized by abnormal deposition of collagen and elastic fibers.
• Typically found in subcutaneous tissues or the gastrointestinal tract.

Observation:

• A rare case of elastofibroma occurred in the appendix.
• This unique appendiceal location required surgical intervention.
• Pathological examination revealed specific findings.

Findings:

• The appendiceal elastofibroma showed features of collagen and elastic fiber deposition.
• Pathology suggested a potential inciting event related to a sclerosed vascular abnormality.
• The pathogenesis remains uncertain, but a reactive process is hypothesized.

Implications:

• This case expands the known anatomical locations for elastofibromas.
• Highlights the importance of considering vascular abnormalities in elastofibroma pathogenesis.
• Contributes to understanding rare gastrointestinal lesions and their reactive origins.
