[Clinicopathologic observation of 36 cases of basal cell carcinoma of the facial region].

The clinicopathologic features of thirty-six cases of basal cell carcinoma in the facial region are reported. There were 26 men and 10 women. The ages of these patients ranged from 14 to 72 years and the largest number of cases (67.74 percent) were encountered in the fifth and sixth decades of life. The average duration was approximately 6 years before patients were treated. The tumors were most frequent in the nose and upper lip. Most of them were histopathologically classified as the solid type. Moderate and extensive irregular peripheral palisading and squamous differentiation were less frequent in the primary basal cell carcinoma.
