Keratoacanthomas, Multiple, of Lower Lip? Presented by Dr. Maximilian E. Obermayer.
The patient, a 62-year-old white male, is married and is a salesman.
Two years ago a "spot" developed on the lower lip and disappeared without treatment after a few months, but then recurred. When the patient was seen in February, 1961, a clinical diagnosis of leukoplakia with central erosion was made. Biopsy was interpreted as squamous-cell carcinoma in situ. The lesion was destroyed by cautery. Since then, tiny spots of "leukoplakia" have been appearing. They were cauterized on 5 occasions, but as new ones continued to erupt, biopsy was performed in the belief that the lesions might be lichen planus.
Family history was noncontributory.
When the trouble with his lip began he consulted the Los Angeles Tumor Institute where radical lip surgery was recommended, an advice which he did not follow.
