Clinicopathological Features And Prognosis of Primary Pulmonary Rhabdomyosarcoma In The Middle-Aged And Elderly: A Case Report And Literature Review

Abstract

Background: Primary pulmonary rhabdomyosarcoma（PPRMS）in the middle-aged and elderly is a very rare event with only a few cases published. To date, only thirty-five cases of PPRMS in the middle-aged and elderly have been published. However, the analyses on clinicopathological characteristics and prognosis of PPRMS in the middle-aged and elderly have not been performed.Case presentation: We report an additional case of PPRMS in the middle-aged and elderly.Conclusions: PPRMS in the middle-aged and elderly was a highly malignant soft tissue tumor with obvious gender characteristics and significant age distribution. Pleomorphic rhabdomyosarcoma (RMS) was the most common subtype, with poor prognosis and significantly prolonged survival time after surgical resection.
