Metastatic colon involvement from primary adrenal gland angiosarcoma: a case report

Area of Science:

• Oncology
• Pathology
• Gastroenterology

Background:

• Angiosarcoma is a rare, aggressive soft tissue sarcoma.
• Primary adrenal angiosarcomas are exceptionally rare, with fewer than 60 cases reported globally.
• This is the first documented case of adrenal angiosarcoma presenting as a colonic metastasis.

Purpose of the Study:

• To report the first case of adrenal angiosarcoma presenting as a colonic metastasis.
• To highlight the diagnostic challenges and importance of immunohistochemistry in such rare cases.
• To emphasize the need for thorough pathological evaluation and interdisciplinary collaboration.

Main Methods:

• Case report of a 68-year-old woman with a history of adrenalectomy.
• Endoscopic identification of a hemorrhagic ulcerative lesion in the sigmoid colon.
• Histopathological and immunohistochemical analysis (CD31, ERG, pan-cytokeratin) of the colonic lesion and review of the adrenalectomy specimen.

Main Results:

• Histopathology confirmed a malignant vascular tumor consistent with angiosarcoma.
• Immunohistochemistry supported the diagnosis of angiosarcoma.
• Review of the adrenalectomy specimen confirmed primary adrenal angiosarcoma, with the colonic lesion identified as a metastasis.

Conclusions:

• This case highlights the unusual presentation of adrenal angiosarcoma as a colonic metastasis.
• Thorough pathological evaluation, including immunohistochemistry, is essential for accurate diagnosis.
• Interdisciplinary collaboration is vital for optimal management of rare malignancies.
