Vaginal Rhabdomyosarcoma in a patient with advanced cervical cancer; a case report and review of literature

Abstract

Rhabdomyosarcoma is very rare in adults accounting for less than 5% of all soft tissue tumours and less than 1% of all malignancies. Vagina is one of the least common sites for occurrence of Rhabdomyosarcoma in the genital tract. We present a case of a 53-year-old woman who is a follow up case of cervical cancer stage IIIB, managed by radiotherapy and chemotherapy. She was doing well till 5 years of her treatment for cervical cancer when she presented with complaints of pain lower abdomen and discharge per vaginum for 10 days. On examination she was found to have an abdominal mass of 18 weeks size and on local examination there was 4X4 cm fixed mass on lower third of vagina arising from left side. MRI abdomen and pelvis was done. Biopsy from the vaginal mass showed features of Rhabdomyosarcoma. Further follow up of the patient was not possible due to lockdown in view of the pandemic. She was last contacted telephonically on 25^th March 2020; she said she was waiting for the lockdown to be lifted so that her further management can take place. This is just one patient; there are many more with other medical conditions all over the world who are losing their lives because of not being able to access medical care due to the present pandemic. New growth in the region of local recurrence in a known malignancy cannot necessarily be the recurrence of the primary tumour. It is important to keep our mind open to other differentials apart from the recurrence of primary malignancy, sometimes it can turn out to be a very rare tumour as we encountered in our case.
