ABSTRACT: Soft tissue sarcomas represent only 1% of all adult
cancers; myxofibrosarcoma is the most common
type that arises in adult extremities, particularly lower limbs (77%),
other less common locations are the trunk (12%) and neck (3%). Usually
presenting as a painless, subcutaneous, slow growing mass with tendency for recurrence, they are prone to have higher
histological grade and metastatic potential after recurrence; even in
optimal multidisciplinary settings patients
can have incomplete resections, making metastatic disease more common after misdiagnosis. We present the case of a
69-year-old male patient with a right infraescapular tumor, presenting
as a painless 15 × 8 cm, mobile mass, with a slow but progressive growth,
history of a previous tumor excised at the same location 5 years prior without
histopathological report.
