Summary
This case report details a rare extra-adrenal adrenocortical carcinoma, initially misdiagnosed as sarcoma. Definitive diagnosis required histopathology and immunohistochemistry, highlighting diagnostic challenges for rare adrenal tumors.
Area of Science:
- Endocrinology
- Surgical Oncology
- Pathology
Background:
- Adrenocortical carcinoma (ACC) is a rare malignancy originating from the adrenal cortex.
- Extra-adrenal ACC is exceptionally rare, with limited documented cases.
- Accurate preoperative diagnosis can be challenging, often requiring advanced imaging and histopathology.
Observation:
- A 52-year-old man presented with a large left-sided abdominal mass.
- Initial imaging (ultrasound, CT) and cytology suggested retroperitoneal sarcoma.
- Surgical exploration revealed the mass was not connected to the adrenal gland.
Findings:
- Histopathological and immunohistochemical examination confirmed the diagnosis of extra-adrenal adrenocortical carcinoma.
- The tumor likely arose from an extra-adrenal adrenal rest.
- This represents the first documented case of extra-adrenal ACC with detailed histological and immunohistochemical analysis.
Implications:
- This case underscores the importance of comprehensive diagnostic workup for abdominal masses with uncertain origins.
- It expands the understanding of rare adrenocortical carcinoma presentations and locations.
- Highlights the necessity of considering rare differentials even with seemingly clear imaging findings.
