Myxomas, characterized by abundant mucoid stroma and spindle cells, represent a subset of benign soft tissue tumors. Intramuscular myxomas in the maxillofacial region are rare, posing diagnostic challenges. We present the case of a 58-year-old male who reported limited jaw movement. Physical examination revealed asymmetry, restricted mouth opening, and left lateral jaw movement. Imaging confirmed a well-defined myxomatous mass. Core needle biopsy confirmed an intramuscular myxoma involving the pterygoid and masseteric muscles. A multidisciplinary team opted for surveillance due to its benign nature. Follow-up at six months showed stable findings, supporting the decision for non-surgical management. This case highlights the diagnostic and management challenges of rare intramuscular myxomas in the maxillofacial region. A comprehensive diagnostic work-up, including clinical, radiological, and histopathological data, is crucial. Non-surgical management, guided by a benign nature, underscores the importance of judicious and multidisciplinary approaches. Regular follow-up contributes to understanding the natural history of intramuscular myxomas, emphasizing the need for vigilant monitoring in soft tissue tumor management.

Article Synopsis
- Soft tissue tumors can grow or stay the same size, but rarely shrink on their own; exceptions include conditions like inflammation and certain benign tumors.
- Intramuscular myxomas are benign tumors that usually appear as slow-growing, painless masses and are typically removed with surgery, which has low recurrence rates.
- This text discusses three unusual cases where intramuscular myxomas in different body areas shrank spontaneously, challenging the usual treatment approaches for these lesions.

Article Synopsis
- The pig tapeworm causes cysticercosis, a parasitic disease affecting the human nervous system, particularly in regions such as Central and South America, Eastern Europe, and parts of India.
- Two pediatric cases of intramuscular cysticercosis were treated successfully with oral prednisolone followed by albendazole, leading to the resolution of symptoms and swellings within three months.
- Diagnosis is often challenging due to nonspecific symptoms, but high-resolution ultrasound and MRI are effective methods for identifying cysticercosis in muscles.
