Key result
Laparoscopic excision plus radiotherapy yields no recurrence or metastasis at 6 months in iliac artery leiomyosarcoma.
Why the study?
Leiomyosarcoma of the right external iliac artery is infrequent and often leads to delayed diagnosis or misidentification, requiring more detailed cases to improve comprehension.
Case Report (n=1)
No
This case highlights the rare occurrence of primary leiomyosarcoma of the external iliac artery and emphasizes the importance of comprehensive imaging and immunohistochemical evaluation for accurate diagnosis.
Warrants vigilance for LMS in iliac-adjacent masses; leaves open standardized diagnostic pathways.
Leiomyosarcoma (LMS) is an uncommon and aggressive form of cancer that originates in the smooth muscles. It possesses the capacity for rapid growth and often manifests with general, nonspecific symptoms arising from the displacement of nearby structures rather than direct invasion. In this particular instance, an 81-year-old woman presented with right lower abdominal pain, leading to the discovery of a mass adjacent to the right external iliac artery. In this case, the patient was misdiagnosed initially because of her nonspecific and poorly distinguished clinical symptoms. The laboratory results were within normal ranges. A well-defined tumor was detected through laparoscopic operation and subsequently surgically excised. The histopathological analysis of the tumor revealed the presence of malignant spindle cells, nuclear pleomorphism, and tumor giant cells. Immunohistochemistry tests indicated positive results for CD34 and Desmin, while CD117 and DOG1 showed adverse effects. It is worth noting that LMS of the right external iliac artery is an infrequent occurrence, potentially resulting in delayed diagnosis and misidentification. To enhance our comprehension of this uncommon cancer, more cases with detailed information are essential.

Olivier et al. (2023) conducted a case report in Leiomyosarcoma of the right external iliac artery (n=1). Laparoscopic surgical excision and radiotherapy was evaluated on Local recurrence or distant metastasis. Laparoscopic surgical excision followed by radiotherapy resulted in no local recurrence or distant metastasis during a 6-month follow-up in a patient with leiomyosarcoma of the right external iliac artery.
