Chemosurgery in cutaneous malignancy

Chemosurgical removal of accessible cancer under microscopic control affords:1. Unprecedented reliability. "Silent" extensions may be followed out and eradicated.2. Conservatism in removal of tissue. With microscopic examination of each layer of tissue removed, it is possible to avoid removing more than one or two millimeters of healthy tissue beyond the extent of the cancer.3. Good cosmetic results in many instances.4. Relative freedom from operative pain.5. Possibly, lower incidence of metastasis.6. Low operative mortality.

Superficial epithelioma of the covered parts of the body

In individuals with primary cutaneous epithelioma there may be a widespread predisposition of the basal cell layer of the epidermis toward the production of growths of this type. The differential diagnosis usually can be made on clinical characteristics, but in some instances differentiation is difficult and a correct diagnosis may be reached only by microscopic examination of the tissue. The radioresistance of this type of epithelioma is emphasized and the selection of the proper method of treatment is discussed. Consideration of the factors of (1) size and location of the lesion, (2) age, and (3) general condition of the patient may result in a decision that, in some cases, no treatment is indicated. Biochemical, cytological and pathological studies of basal cell epithelioma might lead to a clearer understanding of the nature of epitheliomas in general.
