Definition / general
  • Variant of squamous cell carcinoma with spindle cell morphology, associated with poor prognosis
Terminology
  • Squamous cell carcinoma with sarcoma-like stroma, pseudosarcoma (Cancer 1983;52:890)
  • Sarcomatoid squamous cell carcinoma
Epidemiology
Sites
Etiology
  • High risk human papillomavirus (HPV) subtypes have a role in carcinogenesis
Clinical features
  • Pelvic pain, vaginal discharge (Cancer 1983;52:890)
  • Vaginal bleeding and obstructive symptoms can occur due to mass effect
Diagnosis
  • Based on clinical, radiological and thorough pathological examination
Radiology description
  • Imaging required to stage the disease and look for metastasis
Prognostic factors
Case reports
Treatment
Gross description
Microscopic (histologic) description
  • Fascicles of plump spindle cells with homogenous to fibrillar cytoplasm, round to oval vesicular nuclei with multiple nucleoli and numerous mitotic figures
  • Usually tumor will also have well to moderately differentiated squamous cell component, which can be easily missed on a biopsy
  • Therefore thorough sampling recommended (Cancer 1983;52:890, Gynecol Oncol 1993;49:100)
