Table below: Myxoma Margin Vascular pattern Cellularity Stroma Staining characteristics Recurrence rate Image (see Histology) Cutaneous myxoma or Superficial angiomyxoma Poor to moderately circumscribed, multilobular Scattered thin-walled vessels Moderately cellular, bland spindled and stellate cells, variable inflammatory cell infiltrate Abundant mucin with clefts. Up to 30% have an associated epithelial component Vimentin; variable staining with CD34, factor XIIIA, SMA, MSA and S-100 20–30% Cutaneous Myxoma Intramuscular myxoma Poorly circumscribed merges with surrounding muscle Hypovascular variant; hypervascular variant Hypocellular variant; hypercellular variant; bland spindle cells Abundant mucin with cystic spaces. Hypercellular variant has strands of collagen Vimentin; variable staining with actin, desmin, CD34 None 100px Juxta-articular myxoma Poorly circumscribed infiltrates surrounding tissue Focally vascular Focally hypercellular, peripheral spindle cells with occasional atypical cells and mitoses Abundant mucin, 89% of<unk>  contain cystic spaces lined by fibrin or collagen Vimentin; variable staining with actin, desmin, CD34 34% Aggressive angiomyxoma Infiltrative Uniformly distributed medium-sized blood vessels often with prominent hyalinization Low to moderately cellular, evenly distributed round, spindled or stellate cells Loose myxoid to focally collagenous Vimentin, desmin, SMA, MSA, estrogen and progesterone receptor 36–72% Angiomyofibroblastoma Well circumscribed Abundant thin-walled blood vessels Alternating hypercellular and hypocellular areas, perivascular condensations of spindled to epithelioid stromal cells Collagenous to edematous with minimal mucin Vimentin, desmin, CD34, estrogen and progesterone receptor No recurrences reported, but rare<unk>  of sarcomatous degeneration Superficial acral fibromyxoma Pushing to infiltrative Mild to moderately accentuated vasculature Moderately cellular, spindle and stellate cells with a storiform to fascicular pattern, variable mast cells Myxoid to collagenous CD34, EMA, CD99 Recurrence rare and primarily for incompletely excised lesions Neurothekeoma (Nerve sheath myxoma) Well circumscribed, multilobular Hypovascular Moderately cellular, spindled cells in fascicles and whorls Nests of cells separated by collagenous bundles S-100, EMA 47% if incompletely excised 100px 1.SMA, smooth muscle actin. 2.MSA, muscle-specific actin. 3.EMA, epithelial membrane antigen.
