Intramuscular myxoma (100%)

Need more extensive sampling and immunohistochemical stains to exclude myxoid variant of other soft tissue tumours such as nerve sheath or smooth muscle tumours.

Soft tissue, left thigh : Low grade myxoid neoplasm with recurrent potential (90%)
|
Other low grade myxoid tumours should also be cosidered, in particuar, low grade myxofibrosarcoma (10%). More blocks should be taken to see if there are areas with cytologic atypia for low grade myxofibrosarcoma or unusual histologic features for other low grade myxoid tumours. Immunohistochemical studies may be necessary if other low grade myxoid tumours are suspected.

More blocks should be taken to exclude the possibility of low grade sarcoma with myxoid change due to sampling error. Also, immunohistochemical study for S100 protein should be performed to exclude a neural tumour with prominent myxoid change.

Left thigh soft tissue mas : Myxoid soft tissue tumour with no frank anaplasia. Differential diagnosis includes :
1. Benign (50%): Myxoid neurofibroma (S100 positive), neurothekeoma (S100 or EM A positive), myxoid nodular fasciitis (recent onset), intramuscular myxoma (slightly too cellular & vascular).
2. Malignant (50%) : Myxoid liposarcoma, or myxoid MFH, or MPNST.
|
Investigation : Cut more sections to look for specific vascular pattern, cellular pleomorphism or lipoblasts, and do immunostudies.

Low-grade myxoid neoplasm. Probability : 100%
|
Differential diagnosis includes low-grade myxoid neoplasm with recurrent potential, myxoid malignant peripheral nerve sheath tumor, low-grade fibromyxoid sarcoma, low-grade myxofibrosarcoma and myxoid leiomyosarcoma. Would examine more blocks and perform immunostain for S100, Desmin, SMA and CD34, EM for exact differentiation.

Myxoid tumor favour low grade myxofibrosarcoma (80%)
|
Differential diagnoses include intramuscular myxoma (20%) and other low grade myxoid tumor. Suggest sample more blocks and perform immunohistochemical staining including S-100 protein, smooth muscle actin and CD34.
