We describe two rare cases of sarcoidosis presenting as tumor-like muscular lesions and subcutaneous tumors. This highlights an extremely rare subtype of sarcoidosis affecting muscles.
Area of Science:
- Rheumatology
- Pathology
- Dermatology
Background:
- Sarcoidosis is a multisystem granulomatous disease with diverse clinical presentations.
- Musculoskeletal involvement, particularly muscular sarcoidosis, is uncommon.
- Tumor-like muscular sarcoidosis represents an exceptionally rare subtype.
Observation:
- The study reports on two patients diagnosed with sarcoidosis.
- Both cases exhibited unusual muscular sarcoid lesions.
- Subcutaneous tumor formation was a concurrent finding in these patients.
Findings:
- The presented cases exemplify the rare tumor-like variant of muscular sarcoidosis.
- The clinical presentation included both intramuscular lesions and subcutaneous nodules.
- Histopathological confirmation of granulomatous inflammation consistent with sarcoidosis was established.
Implications:
- This report expands the understanding of sarcoidosis's varied manifestations.
- It emphasizes the importance of considering rare subtypes in differential diagnoses.
- The findings contribute to the literature on tumor-like presentations of sarcoidosis.

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...
