Summary
Undifferentiated uterine sarcoma, a rare cancer, can present with unusual symptoms. This case highlights a rare instance of humeral metastasis from this aggressive endometrial cancer.
Area of Science:
- Oncology
- Pathology
- Gynecologic Oncology
Background:
- Undifferentiated uterine sarcomas are rare and aggressive gynecologic malignancies.
- These cancers often present at advanced stages, posing diagnostic and therapeutic challenges.
Observation:
- A geriatric female presented with severe right arm pain due to a pathologic humeral fracture.
- Imaging revealed a large abdominal mass, suspected to be of uterine origin.
- Biopsies confirmed poorly differentiated metastatic sarcoma in the humerus and undifferentiated uterine sarcoma.
Findings:
- The patient's humeral lesion was pathologically confirmed as metastatic undifferentiated uterine sarcoma.
- This represents an uncommon metastatic pattern for this rare uterine malignancy.
Implications:
- Highlights the importance of considering rare metastatic sites in advanced uterine sarcomas.
- Emphasizes the need for comprehensive evaluation in patients with unexplained fractures and masses.

01:19Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
