Background: Basal cell carcinoma (BCC) is the most common malignant neoplasm in humans and its incidence has increased over the last decades. Occupational sun exposure and exposure to ultraviolet radiation is the main environmental risk factor associated with its cause.
Aims: To estimate the prevalence of basal cell carcinoma among outdoor workers attending Baqubah teaching hospital outpatient clinic.
Patients and methods: A cross sectional study was conducted in Baqubah teaching hospital during the period from 1st September 2014 to 31th march 2015. The total number of cases was (30).This study was carried in outpatient clinic of dermatology and venereology; diagnosed by dermatologists.
Results: The prevalence of BCC is more common in male (73.3%), female(26.7%), mean age(55.4) and, prevalence distribution by occupation common in farmer 40%. Prevalence more in smokers (60%) than non-smokers (40%) and it is more common in fair skin type (76.7%) than other, brown (20%) and black (3.3%). prevalence in eye color seen that black eye (53.4%), brown (23.3%), green (13.3%), blue (10%). The prevalence according to site more common in head (83.2%) than other protected site by clothes as upper limb (6.6%) , lower limb (6.7%) and abdomen (3.3%). The positive family history seen in (40%) of cases. Prevalence of BCC according to the period of sun exposure, seen that increase with increase sun expose, it is up to 100% among patient expose more than 3hrs in day, the percentage as follows; 3hrs (13.3%), 4hrs (16.6%), 5hrs (20%), 6hrs (23.3%) and 7hrs (26.6%).
Conclusions: We conclude that the prevalence of BCC is high after age of 40 years, and is more common in male, The risk of BCC increase with increase hours of exposure each day. More common in smoker than non smoker, and is more common in white skin than other types of skin . although eminently curable when the diagnosis is made promptly and the lesion is treated in its early phase. An accurate diagnosis of BCC is achieved through careful clinical and histopathological examination.
