Epithelioid leiomyosarcoma: An unusual presentation.

Area of Science:

• Gynecologic Oncology
• Surgical Pathology
• Medical Oncology

Background:

• Uterine mesenchymal tumors are diverse and can be difficult to diagnose.
• Leiomyosarcoma (LMS) is a rare uterine malignancy originating from smooth muscle tissue.
• LMS typically affects postmenopausal women and presents with abnormal uterine bleeding, often with an aggressive course and poor prognosis.

Observation:

• A 57-year-old menopausal woman presented with a large abdominal swelling.
• The swelling was observed to be infiltrating adjacent structures.
• Surgical resection was performed.

Findings:

• Histopathological evaluation confirmed a diagnosis of epithelioid LMS.
• Immunohistochemistry was utilized to confirm the diagnosis.
• Epithelioid LMS is a rare subtype of uterine sarcoma.

Implications:

• Accurate diagnosis of uterine mesenchymal tumors is crucial for appropriate treatment.
• Prompt diagnosis and surgical management are essential for patients with epithelioid LMS.
• This case underscores the role of advanced diagnostic techniques like immunohistochemistry in challenging oncological cases.
