Abstract:
Introduction: Primary Extraskeletal Myxoid Chondrosaroma (EMC) of the vulva is a rare mesenchymal neoplasm. The myxoid tumour differential diagnosis on a core biopsy can be quite challenging. To date, few cases have been reported in the literature. Case Report: A 42-year old woman noticed a swelling on the right side of the labia, thought to be a Bartholin's cyst i n 2011. She was managed conservatively. She had drainage and marsupialization under general anaesthesia. This resulted in extreme bruising of the vulva. This was managed with antibiotics and non-steroidal anti-inflammatory medication, and it resolved after 3 weeks. Six months later, the patient presented again with a persistent vulval mass. A biopsy was obtained under general anaesthesia, and it showed a myxoid tumour with differential diagnosis of low grade chondroid tumour. An MRI was performed to assess the extent of the disease. The tumour was excised. At surgery, a 7 x 5 cm lobulated, extremely vascular vulval tumour was found. The tumour was inseparable from the inferior pubic ramus of the pelvic bone. A complete macroscopic resection was obtained. Histology confirmed low grade myxoid chondrosarcoma. Conculsion: Vulval lesions with unusual characteristics or insidious evolution in the labia majora or Bartholin's glands area should be carefully and pr omptly investigated. Differential diagnosis of myxoid tumours in the vulva should include myxoid chondrosarcoma amongst other diagnoses.
