¿Neoplasma de tejidos blandos o hematoma crónico? Un dilema diagnóstico.(In.)

Chronic soft-tissue haematomas are infrequently reported in the literature. We present a case of a slowly expanding post-traumatic chronic soft-tissue haematoma located anterior to the knee and leg, occurring in a region previously unreported. Both clinically and radiologically, it was impossible to distinguish the haematoma from an aggressive soft-tissue neoplasm. We review the literature and discuss the diagnostic problems related to this uncommon presentation.
