Metastatic soft tissue squamous cell carcinoma.
Metastatic squamous cell carcinoma of the soft tissue is extremely rare. We report two patients with soft tissue metastasis from squamous cell carcinoma of the cervix in one and scalp in another. Case 1: A 63-year-old black woman with a history of cervical cancer presented with a painful mass over the right scapula. An incisional biopsy revealed squamous cell carcinoma. She underwent radiation treatment followed by wide local excision with en bloc resection and a myocutaneous flap closure. Case 2: A 46-year-old white man with a history of squamous cell carcinoma of the scalp and two kidney transplantations requiring long-term immunosuppression presented with a 2-month history of a left proximal arm mass. Magnetic resonance imaging revealed that the mass was within the triceps muscle and fixed to the humerus. Biopsy revealed squamous cell carcinoma. He underwent a shoulder disarticulation for tumor invasion into the adjacent humerus and neurovascular bundles. The patients remain disease-free at 12 and 8 months, respectively. To our knowledge there are no reports of soft tissue squamous cell carcinoma metastatic from the cervix and only rare cases from the lung, head, and neck. The optimal mode of treatment and prognosis is undefined in these patients because of its rare incidence. Surgery and radiation with curative intent were used.
