[Basal cell epithelioma of the lip. Analysis of 42 cases]

Basal cell epithelioma of the lip. An analysis of 42 cases. The authors carried out a histopathological and epidemiological study of 42 basal cell epitheliomas of the lip. Both sexes were equally affected (male to female ratio 0.9:1) but the females were significantly older than the males (mean age: 70.7 years vs 62.3 years respectively). The incidence in the province of Trieste was 1.44%... for males and 1.46%... for females. More than 80% of the lesions (35 cases) consisted in solid forms, but there were also 4 cheratotic basal cell epitheliomas, 1 fibrosing epithelioma and 1 basosquamous epithelioma. In 2 of the males there was a recurrence a year after the surgical exeresis and in 6 cases another epithelioma was synchronous or metachronous to the lip epithelioma. Despite the fact that in 3 cases invasion of the muscular wall was noted and in another case the neoplasm had infiltrated and eroded the left nostril and the lower part of the septum, no patient died from the tumour nor were any metastasis observed.
