Introduction
Due to a relatively high recurrence rate of facial basal cell carcinoma (BCC), its morbidity is very significant.

Aim
To analyse the expression of α-SMA, E-cadherin, Ber-Ep4 and MOC-31 as predictors of local recurrence in a group of patients with primary and recurrent BCCs of the face in correlation with histological and clinical data.

Material and methods
The study cohort included 79 patients with facial BCC (52 with primary BCC and 27 with recurrent BCC) who were treated at the Department of Cranio-Maxillofacial Surgery of the Jagiellonian University, Krakow in 1997–2009.

Results
Significant risk factors for local recurrence included: recurrent tumour (p = 0.001), multifocal BCC (p = 0.01), incomplete tumour excision (p = 0.02) and the aggressive infiltrating histologic subtype of BCC (p = 0.05). In the group of primary BCCs, positive expression of stromal α-SMA (p = 0.03) correlated with a statistically significant higher recurrence rate and so did positive expression of α-SMA in tumour cells of recurrent BCC (p = 0.002). In the group of primary aggressive BCC subtypes, reduced expression of MOC-31 was also associated with a higher rate of relapse (p = 0.02).

Conclusions
Our findings provide information about α-SMA and MOC-31 expression in primary and recurrent BCCs. These data may contribute to the formulation of a more targeted treatment plan and follow-up strategy for patients with facial basal cell carcinoma.
