The lipoma is the most common tumor of the body and can be found in virtually every tissue or organ. However, a parosteal lipoma is an extremely rare benign neoplasm consisting mainly of mature adipose tissue contiguous to the underlying periosteal bone. The incidence of this tumor is 0.3% of all lipomas. Parosteal lipoma is considered to be one of the rarest primary bone tumours. It is composed of mature fat cells and varying, though small, quantities of fibrous and vascular tissue. At the gross pathological examination, parosteal lipomas appear as greasy yellowish masses that adhere to the underlying periosteum. Over 200 cases of parosteal lipoma have been described in the literature. The diagnosis of a parosteal lipoma can be made by the histological findings, the confirmation of fat content at Magnetic Resonance or Computed Tomography. Parosteal lipomas are rare entities associated with periosteal involvement depending on their location. Current management should include computed tomographic scanning and magnetic resonance. Surgery, which is mandatory treatment, requires particular attention to ensure that any periosteal involvement is removed completely.

Abstract
The lipoma is the most common tumor of the body and can be found in virtually every tissue or organ. However, a parosteal lipoma is an extremely rare benign neoplasm consisting mainly of mature adipose tissue contiguous to the underlying periosteal bone. The incidence of this tumor is 0.3% of all lipomas. Parosteal lipoma is considered to be one of the rarest primary bone tumours. It is composed of mature fat cells and varying, though small, quantities of fibrous and vascular tissue. At the gross pathological examination, parosteal lipomas appear as greasy yellowish masses that adhere to the underlying periosteum. Over 200 cases of parosteal lipoma have been described in the literature. The diagnosis of a parosteal lipoma can be made by the histological findings, the confirmation of fat content at Magnetic Resonance or Computed Tomography. Parosteal lipomas are rare entities associated with periosteal involvement depending on their location. Current management should include computed tomographic scanning and magnetic resonance. Surgery, which is mandatory treatment, requires particular attention to ensure that any periosteal involvement is removed completely.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
