In the differential diagnosis of lipomas, fibromatous hamartoma, liposarcoma, fibrolipoma and teratoma may be mentioned as fat-containing lesions of peripheral localization. However, these lesions are different from lipomas in that they contain soft tissue components and are not homogeneous. Furthermore, they are much larger than lipomas, are infiltrative and their CT density is greater than -5...

Storiform collagenoma is a rare tumor, which originates from the proliferation of fibroblasts that show increased production of type-I collagen. It is usually found in the face, neck and extremities, but it can also appear in the trunk, scalp and, less frequently, in the oral mucosa and the nail bed. It affects both sexes, with a slight female predominance. It may be solitary or multiple, the l...

The most common benign tumors of the mesenchyme are the lipomas. Benign fatty tumors can arise in any location in which fat is present. Fibrolipomas are characterised by fat modules. Most patients affected by such tumors are in the fifth or sixth decade of life. When very close to vital structures such as joints, they may cause functional limitations as well as pain. Osseous and chondroid metap...

Fibrolipomas are benign lesions conformed by fat and connective tissue, classified as histologic variants of lipomas. They are rarely located in the head and neck and represent less than 0.6% of the benign tumors of the larynx and hypopharynx. Their clinical presentation depends on its location and size. We present the case of a 51-year-old male patient who reported progressive dyspnea, dysphag...

Lipomas are the most common benign tumors of the mesenchyme; they are composed of mature lipocytes. Benign fatty tumours can arise in any location in which fat is present. Most patients affected by such tumours are in their fifth or sixth decade of life. Only rarely are children affected. Lipomas may be single or multiple. Multiple lipomas are more common in women; many are seen in a familial s...

An 8/2 -year-old girl presented with a one-month history of a lump on the left thoracic area, just off the midline. The girl was otherwise well. Her history was uneventful and her development had been normal. She had no serious illnesses. Examination revealed a soft, diffuse, non-tender swelling 3 x 3 cm over the upper thoracic vertebrae to the left of the midline, just below the scapulae. It d...
