title: Basosquamous carcinoma: is it an aggressive tumor?
abstract: Basosquamous carcinoma is a rare cutaneous tumour that is considered an aggressive type of basal cell carcinoma with an increased risk of recurrence and metastases. This impression has been perpetuated in the literature, despite limited scientific data and conflicting results of some authors. This present study was aimed to evaluate the clinical-pathological features of this tumour and follow-up of a series of basosquamous carcinoma. Basosquamous carcinoma patients who underwent surgical excision between January 2000 and February 2012 were analyzed retrospectively. Their medical files were reviewed and the corresponding routinely stained sections (with hematoxylin-eosin) were re-evaluated by two pathologists. Thirty-five patients with basosquamous carcinoma were operated on in this period. Most tumurs were located in the head and neck area (94%), and the mean age of the patients was 69.8 years. Margin involvements were seen in 11 patients (31.4%) and all of them underwent re-excision. There was only one local recurrence. There was neither regional lymph node nor distant metastasis in this series. The recurrence rate of basosquamous carcinoma is found as 4%, lower than that of most other similar studies. Further pathologic studies are needed to better classify basosquamous carcinoma and to increase consistency between the results of studies. Surgical excision and regular follow-up are considered as the treatment of choice.
