Ultrasound demonstrates a homogeneous and circumscribed hyperechoic area; however, angiolipomas
and low-grade liposarcomas containing both benign and malignant fat tissue may mimic lipomas in ultrasound study.9 With computed tomography (CT scan), lipomas exhibit smooth well-defined edges, a uniform density that is comparable to the normal fat, and do not enhancement with intravenous contrast.1
The differential diagnosis should include other lipomatous tumors, such as liposarcomas, angiolipomas
, spindle-cell lipomas, among others (MENTZEL & FLECHER, 1995; KIM et al., 2013).
Familial cases of angiolipomas
, a variant of lipomas, have reported an autosomal dominant inheritance (1).
which are composed of fatty tissue and vascular elements are benign tumors and usually present with a slowly progressive course of neurological deterioration.
generally present as encapsulated subcutaneous tumors.
The treatment of multiple angiolipomas
by liposuction surgery.
Its different variants include angiolipomas
, neomorphic lipomas, spindle cell lipomas, and adenolipomas.
Although segmental leiomyomas are referred to as zosteriform leiomyoma by some writers, do not show a dermatomal distribution.3 Painful skin lesions, such as granular cell tumours, eccrine spiradenomas, dermatofibromas, neuromas, neurilemmomas, glomus tumours, angiolipomas
and endometriomas, should be considered in the differential diagnosis of cutaneous leiomyomas.5
Lipomas, lipomatosis, angiolipomas
, chondroid lipomas, lipoblastoma, lipobalostomatosis, spindle cell lipoma and pleomorphic lipomas are lesions that can mimic the condition.
are rare tumors of endothelial cells that have been documented in both humans and animals [1-3].
They include fibrolipomas, which have a higher component of connective tissue; myxolipomas, which contain gelatinous stroma; spindle-cell lipomas, which feature fibroblastoid spindle cells; and angiolipomas
, which are characterized by extensive vascularization.
