Grossly, the tumor usually presents a sharply circumscribed mass with smooth, bosselated
, or lobulated external surface. Microscopically, classical morphological appearance including 'patternless pattern' caused by variable spindled cells arrayed in the stroma.
On exploratory laparotomy, there was an encapsulated, bosselated
, irregular mass, 15x13x12 cm in size and with restricted mobility.
External surface of larger mass was bosselated
and had attached vas deferens measuring 4 cm in length.
In our case the spleen was misshapen grossly due to bosselated
surface caused by bulging nodules and the cut surface was studded with numerous cysts of various sizes scattered throughout.
A papillary configuration may be appreciated in larger lesions, although they are more frequently bosselated
On examination, there was a 6x4 cm nontender bosselated
firm swelling over the dorsal and medial aspects of the first toe and the adjoining web space.
Intraoperatively, two tumors were seen in the left parapharyngeal space; both had a bosselated
Myxomas are thought to derive from multipotential mesenchymal cells, and have a variable macroscopic appearance ranging from soft and friable to smooth and bosselated
.  Most tumours are found in the atria, with 75% originating from the fossa ovalis region of the left atrium.
The tumour arises from the cortex as a protruding mass with a rounded bosselated
usually brownish surface.
On panoramic radiographs, small tori palatini are not well demonstrated owing to overlying bony structures; larger tori can be easily detected with a bosselated
or multi-lobulated appearance.
Computed tomography showed a large lobulated solid cystic 5x9 cm mass in right adnexa which was well defined, bosselated
and had hyper vascular enhancement with fatty component and calcific foci suggestive of a teratomatous mass.
An enlarged right ovary with bosselated
outer surface and intact capsule was noted.
