- Metastases to Skin and Muscle: Facts
- Uncommon and usually harbors a bad prognosis
- Sites of origin include lung cancer, renal cell carcinoma, thyroid cancer, melanoma, breast cancer and gyn tumors. - “Skeletal muscle metastases from cancer occur rarely and there are no clear guidelines for appropriate work-up and management of these lesions. Specifically, soft muscle metastases to the abdominal region provide exceptionally difficult treatment decisions based on location. While these can occur following percutaneous or surgical procedures in patients with head and neck cancers, it is extremely rare that one should occur in a patient without a history of any such procedures. Soft tissue metastases to muscle and skin generally represent undiscovered disease elsewhere and an overall poor prognosis.”
Isolated skeletal muscle metastasis following successful treatment of laryngeal cancer: case report Klune JR et al International Seminars in Surgical Oncology 2010, 7:1 - “Most commonly abdominal wall metastases for head and neck cancers, including laryngeal, occur after percutaneous, laparoscopic, or incisional procedures. Metastatic disease at the site of a percutaneous endoscopic gastrostomy (PEG) tube placement is known to occur with many different types of head and neck cancers, most widely hypothesized to be due to direct seeding by endoscopic dislodgement and displacement of cancer cells. Incidence of metastatic lesions from head and neck cancers to PEG sites is unknown but estimated to be 1-3%. It has been suggested that in these cancers, either laparoscopic or radiologic tube placement offers a safer alternative, although recently a case of gastrostomy-site metastasis following radiological insertion has been reported.”
