Masseter idiopathic calcinosis circumscripta: A rare condition.

Area of Science:

• Biomineralization and ectopic calcification research.
• Musculoskeletal and craniofacial pathology.
• Rare disease diagnosis and management.

Background:

• Calcinosis involves ectopic calcification in soft tissues, with calcinosis circumscripta being localized muscle calcification.
• Calcinosis circumscripta can be metastatic, dystrophic, or idiopathic, differing from calcinosis universalis seen in inflammatory myopathies.
• The masseter muscle is an uncommon site for calcinosis circumscripta.

Observation:

• A case report of a 22-year-old female presenting with facial swelling.
• The swelling was localized to the left middle third of the face.
• Clinical presentation suggested a rare masseter muscle calcification.

Findings:

• Idiopathic calcinosis circumscripta of the masseter muscle is a rare condition.
• Pre-operative diagnosis poses a significant challenge due to numerous differential diagnoses.
• A combination of clinical history and examination aided in suspecting this rare diagnosis.

Implications:

• Highlights the diagnostic challenges associated with rare masseter muscle calcifications.
• Emphasizes the importance of considering idiopathic calcinosis circumscripta in facial swelling cases.
• Suggests the need for comprehensive diagnostic approaches for localized ectopic calcifications.
