The cockade sign is a radiological feature associated with intraosseous lipoma, a rare benign tumor of the bone composed primarily of mature adipose tissue. [1] [2] This sign describes the characteristic appearance of a central calcification or ossification surrounded by radiolucent fatty tissue on imaging, resembling a bullseye or cockade. [3]
Lipomas have a prevalence of roughly 2 out of every 100 people. [2] Lipomas typically occur in adults between 40 and 60 years of age. [1] Males are more often affected than females. [1] They are the most common noncancerous soft-tissue tumor. [5] The first use of the term "lipoma" to describe these tumors was in 1709. [6]
The lipomas are well-encapsulated, slow-growing, benign fatty tumors. The distribution is defined as being focused in the trunk of the body and extremities. [2] Familial Multiple Lipomatosis can be identified when multiple lipomas occur in multiple family members that span different generations. [2] Some people may have hundreds of lipomas ...
Many discrete, encapsulated lipomas form on the trunk and extremities, with relatively few on the head and shoulders. [1] In 1993, a genetic polymorphism within lipomas was localized to chromosome 12q15 , where the HMGIC gene encodes the high-mobility-group protein isoform I-C. [ 2 ] This is one of the most commonly found mutations in solitary ...
Lipomas are usually diagnosed clinically, although imaging (ultrasound, computed tomography, or magnetic resonance imaging) may be utilized to assist with the diagnosis of lipomas in atypical locations. [24] The main treatment for lipomas is surgical excision, after which the tumor is examined with histopathology to confirm the diagnosis. [24]
Dercum's disease is a rare condition characterized by multiple painful fatty tumors, called lipomas, that can grow anywhere in subcutaneous fat across the body. [1] Sometimes referred as adiposis dolorosa in medical literature, Dercum’s disease is more of a syndrome than a disease (because it has several clinically recognizable features, signs, and symptoms that are characteristic of it and ...
The ultrasound showed three lesions on Violette's liver, initially prompting the team to schedule an MRI for the baby. After she was admitted to the hospital, the doctors told the Sewells they ...
The presence of eccrine sweat glands are used to distinguish the tumor from a common lipoma. Size and the development of the capsule (tissue surrounding the tumor) can also aid in diagnosis. Size and the development of the capsule (tissue surrounding the tumor) can also aid in diagnosis.
