Differential diagnosis in the pediatric population and in this anatomical location can be done with cranial/nodular fasciitis, low-grade fibromyxosarcoma, low-grade myofibroblastic sarcoma, lipofibromatosis, malignant peripheral nerve sheath tumor, myofibroma, leiomyosarcoma, inflammatory myofibroblastic tumor, and hypertrophic scar [13, 27].
FNAC of low grade fibromyxosarcoma yielded myxoid material and smears showed moderate cellularity of loosely cohesive spindled fibroblast-like cells with moderate atypia arranged in a myxoid background.
Less common types of STS occurring in the external ear included sarcoma (NOS), spindle cell carcinoma, giant cell carcinoma, epithelioid sarcoma, fibrosarcoma (NOS), fibromyxosarcoma, pigmented dermatofibrosarcoma, liposarcoma (NOS), myxoid liposarcoma, epithelioid leiomyosarcoma, embryonal rhabdomyosarcoma, mixed tumor malignant, and carcinosarcoma (NOS).
IMT is distinguished from myxofibrosarcoma and low-grade fibromyxosarcoma by the presence of diffuse inflammation and absence of typical delicate "curvilinear" vessels characteristic of these sarcomas.
