Summary
Striated muscle hamartoma (SMH) is a rare benign skin growth. This case highlights an SMH presenting as a congenital chin plaque in a newborn, offering insights into its presentation.
Area of Science:
- Dermatology
- Pathology
- Pediatric Surgery
Background:
- Striated muscle hamartoma (SMH) is an uncommon benign lesion.
- Typically congenital, polypoid, and located on the head and neck.
- Characterized by dermal and subcutaneous fascicles of striated muscle.
Observation:
- A case report of a newborn girl with SMH.
- Presented with a congenital infiltrated plaque on the chin.
- No other associated anomalies were noted.
Findings:
- Histopathologic confirmation of SMH.
- Demonstrates individualized fascicles of striated muscle in the dermis and subcutaneous tissue.
- Unusual presentation as an infiltrated plaque rather than a polypoid mass.
Implications:
- Expands the known clinical spectrum of SMH.
- Highlights the importance of considering SMH in congenital head and neck lesions.
- Contributes to understanding the histopathologic variations of this benign tumor.

Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

Skeletal muscle is the most abundant type of muscle in the body. Tendons are the connective tissue that attaches skeletal muscle to bones. Skeletal muscles pull on tendons, which in turn pull on bones to carry out voluntary movements.

01:48Classification of Skeletal Muscle Fibers
48.4K
Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

Skeletal muscle cells, also called muscle fibers, are distinctly elongated, multi-nucleated, slender biological units. They are packed with specialized structures designed to facilitate their primary function, which is contraction.
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...

The connective tissues play a significant role in arranging the muscle fibers into a hierarchical structure that forms a complete muscle. Consider a muscle like the bicep brachii, commonly called the bicep. This muscle comprises thousands of muscle fibers enclosed by a protective layer of connective tissue called the endomysium. The endomysium is primarily composed of reticular fibers, a type of thin collagen fiber. It allows the exchange of nutrients and waste products at the fiber level,...

8.3K
Smooth muscle tissue is a type of muscle tissue that can be found lining various vital organs in the human body, including the lungs, blood vessels, digestive tract, and respiratory tract. This type of tissue is responsible for regulating the movements of these organs, playing crucial roles in the functioning of various systems, including the vascular, digestive, respiratory, and urinary systems.
