Objectives:
Tumors of the spermatic cord and epididymis are rare, and their exact incidence is difficult to determine. Ninety percent of extra testicular tumors within the scrotum are found in the spermatic cord, where 30% is malignant (1).
Methods:
In this case report we present an unusual spermatic cord tumor, i.e. myositis ossificans (MO). To the best of our knowledge, MO of the spermatic cord has not been reported before in the literature.
Conclusions:
MO should be considered in the differential diagnosis of the spermatic cord tumors.

Microscopic Anatomy of Skeletal Muscles
The muscle sarcolemma is a plasma membrane enclosing each muscle cell that conducts electrical signals called action potentials. The sarcolemma extends into the cell to form T-tubules, ensuring the neural impulses are uniformly distributed across the entire muscle...

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
