A rare case of Extraskeletal Ewing’s sarcoma of the axilla in a primigravida

Ewing’s sarcoma is a rare cancerous tumor of bone or soft tissue that usually occurs mostly in young adults. The diagnosis of Ewing’s sarcoma in pregnancy, most especially the subtype extraskeletal Ewing’s Sarcoma, is very rare with only few cases published in the literature worldwide. We present a case of a primigravida diagnosed with extraskeletal Ewing’s sarcoma at 6 weeks age of gestation. Currently, because of the rarity of this condition, there is lack of a universal consensus on the recommended therapeutic approach. A multidisciplinary management involving the generalist obstetrician, perinatologist, medical oncologist, and neonatologist was initiated at the outset to provide timely balance between optimal maternal treatment and fetal well-being. The maternal and fetal condition was stable all throughout the course of the chemotherapy using doxorubicin during pregnancy. Close interdisciplinary coordination regarding the treatment plans across these subspecialists resulted in a successful pregnancy outcome.
