Four Cases of Successfully Treated Chronic Expanding Soft Tissue Hematoma
Case 1 was a 40-year-old man who presented with painless swelling of the right sole that increased gradually in size for 4 months. An examination revealed a firm, skin-colored, subcutaneous tumor adhering to the skin (). There was no recent history of trauma or anticoagulant medication. A laboratory examination, including a coagulation profile, was within normal limits. A magnetic resonance imaging (MRI) examination revealed a 2.5×2.5 cm well-encapsulated mass, which was removed completely by surgery (). A histopathological examination revealed a fibrotic capsule, inflammatory cellular infiltration, and organized blood (, ); the lesion was diagnosed as CEH. The patient's postoperative course was uneventful and his tumor has not recurred after 2 years.
