Abstract:
A 42-year-old woman was admitted to our hospital complaining of left ptosis, diplopia, and muscle weakness. A diagnosis of myasthenia gravis was made. Chest roentgenograms, computed tomography (CT), and magnetic resonance imaging (MRI) showed a large anterior mediastial mass and suggested thymolipoma. Extended thymectomy was performed via a median sternotomy. Histopathological examination revealed that the tumor consisted of mature adipose tissue and weighed 1,500 grams, in which thymic tissues with Hassall' s corpuscles but without a germinal center were contained. The histological appearance was compatible with a typical thymolipoma. This is the 24th reported case of thymolipoma associated with myasthenia gravis.

Disorders of the Skeletal 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...
Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
