خصوصیات مردم شناختی و آسیب شناسی کارسینوم سلول سنگفرشی پوست و لب: بررسی بیماران مراجعه کننده به بیمارستان رازی تهران

Squamous cell carcinoma, a cancer of keratinocytes origin, mostly involves sun-exposed areas of the skin. To study the pathologic and demographic features of this disease, records of 395 patients of squamous cell carcinoma of skin and lip were reviewed. Most of the patients (83%) aged 40 years or more at the time of diagnosis. Respectively, 74.4% and 75.8% of cases with skin and lower lip carcinoma were men, but in upper lip cases frequencies of both sexes were equal. The number of patients referred from western and north-western provinces were much more than those of other provinces of the country. The most frequent histologic stage was grade I (53% and 58.8% in skin and lip carcinoma, respectively), showing that most patients visit physicians early enough, and are diagnosed in early stages of the disease.
