Basal cell epitheliomas occur most frequently on the face and have very variable appearances: cicatricial and flat, ulcerous, even deep, and nodular, sclerodermiform, or pigmented. A very positive diagnostic finding is small epitheliomatous pearls often grouped together at the periphery of the lesion. Though the effects of these lesions are purely local, as metastases never occur, they frequently have a tendency to relapse.
基底细胞上皮瘤最常发生于面部，外观变化多样：有瘢痕性和平坦型、溃疡型、甚至深部型，以及结节型、硬皮病样型或色素沉着型。一个非常有诊断意义的表现是小的上皮瘤样珠，常聚集在病变周边。虽然这些病变的影响仅限于局部，因为从不发生转移，但它们常常有复发倾向。
