摘要
Objective
Atypical fibroxanthoma is a rare mesenchymal tumour of skin that develops on skin of elderly patients. We analysed our patients with atypical fibroxanthoma over the last 8 years.
Patients and methods
We analysed the pathology files of our hospital for the period 2001-2009. In all cases, histology and immunohistology were performed. Data on co-morbidities, treatment and outcome were obtained.
Results
We identified 25 patients (except two female patients, the rest were men) aged 52-95 years (mean: 79.5 years; standard deviation +/- 9.06 years). All tumours were localized in the head and neck region, except a single tumour on the shoulder. Fourteen patients had a cancer history, six had actinic keratoses or Bowen's disease (n = 1). Five patients had cardiac surgery or pacemaker, one each had a renal transplant, systemic sarcoidosis or non-Hodgkin's lymphoma. Medical history was positive for radiotherapy or chemotherapy in four patients. Histology showed a spindle-shaped dermal and subcutaneous tumour growth intermingled with multinucleated giant cells. The phenotype of tumour cells was vimentin-positive, but S100- and keratin-negative. Some tumours showed a focal expression of CD68. Complete microhistographic controlled surgery ('Mohs like') was possible in all cases followed by mesh-graft transplantation in three patients. Eighteen patients showed a complete remission. Four patients had a relapse within 2 years of follow-up treated by surgery. One patient is still under radiotherapy. All patients with a safety margin of 2 cm had no recurrence or relapse during follow-up.
Conclusions
Micrographic controlled surgery with wide 2 cm safety margins is the treatment of choice. A regular follow-up for the next 5 years is recommended.
