Abstract

Primary alveolar rhabdomyosarcoma of breast in a 13 year old female with cardiopulmonary metastases and cyto-histological correlation: A case report

Highlights

  • Rhabdomyosarcoma is the commonest soft tissue sarcoma of childhood

  • We present a case report of a juvenile primary breast alveolar rhabdomyosarcoma

  • These findings and the histo-morphological pattern supported the diagnosis of Alveolar rhabdomyosarcoma, and excluded small cell carcinoma, lymphoma, Primitive neural ectodermal tumour (PNET) or epithelial neoplasm

Summary

Introduction

Rhabdomyosarcoma is the commonest soft tissue sarcoma of childhood, accounting for 5% of malignant tumors in this age category [1, 2]. The patient was referred to our institution one year after the right breast lumpectomy She came with right breast tumour, associated nipple oedema and satellite areolar tumour nodules (Figure 1). A cytological diagnosis of malignant right breast neoplasm was made, differential of which included poorly differentiated carcinoma, rhabdomyosarcoma, Ewing’s’ sarcoma and lymphoma. A poorly differentiated or epitheloid leiomyosarcoma exhibit the same immunostaining profile but not the histomorphology of round small dark monotonous neoplastic cells separated by fibro vascular alveolar like septa seen in this case report. These findings and the histo-morphological pattern supported the diagnosis of Alveolar rhabdomyosarcoma, and excluded small cell carcinoma, lymphoma, Primitive neural ectodermal tumour (PNET) or epithelial neoplasm. A number of tumour nodules were seen on the heart (Figure 7) while both gross and histopathological findings were consistent with extensive tumour infiltration of the myocardium (Figure 5)
