Not All Basal Cell Carcinomas Are Created Equal

By John “Lucky” Meisenheimer, MD and John Meisenheimer, VII

Occasionally a patient will tell me their “doctor friend” recommended that they don’t need treatment for a basal cell carcinoma because it will never hurt you. “Doc, he said it’s only a basal cell carcinoma.” Dermatologists fully recognize this as a genuinely cringe-worthy statement. You don’t need to see too many people missing various parts of their facial anatomy to know this advice is blatantly wrong. Even in this modern time of medical miracles, people still die from neglected basal cell carcinomas. When pressed for the name of their “doctor friend,” it usually comes up as I don’t remember their name, or it ends up being “Doctor Google.”

It is true a superficial basal cell carcinoma on the torso probably would take years and years for it to cause any sort of significant morbidity to a patient. But, on the other hand, even a small basal cell on the torso will continue to grow if left untreated slowly. What might have been a simple, inexpensive procedure now, a decade later, has turned into a monster of aggravation, discomfort, and cost.

Although metastatic disease risk is low with basal cell carcinomas, it is certainly not zero. Several people die each year from basal cell carcinoma. Even more, patients can have disfiguring bouts with cancer losing various parts of anatomy such as nose, ears, eyes, etc. What a lot of patients and even some physicians are not aware of is that not all basal cell carcinomas are created equal. There are several different histologic growth patterns. These varying histologic types can each behave differently and require different treatment plans. As mentioned before, a superficial basal cell carcinoma is probably not going to cause a great deal of physical damage unless neglected for long periods. There are other types of basal cell carcinomas; morpheaform and sclerosing basal cell carcinomas with infiltrating growth patterns. These cancers left untreated can cause a significant amount of morbidity in shorter periods measured in months, not years. Aggressive basal cell cancers can also become neurotropic, meaning that they “wrap” around a nerve and can track down its length. Neurotropism can be particularly dangerous, especially if this is on the face and affecting a nerve that happens to pass through a foramen into the brain. Clearly, not a good scenario. Pathology of an infiltrative Basal cell carcinomas, limited to the skin, tend to be very amebasal cell carcinoma. nable to treatment in a variety of different ways. Even as a Mohs surgeon I can think of at least half a dozen different ways that I have treated basal cell carcinomas. Not all basal cell carcinomas need Mohs surgery. Each case of basal cell carcinoma should be evaluated individually and in consideration as to the best method of treatment based on its histologic growth pattern, location, and physical condition of the patient. The great news about basal cell carcinoma, even though it is the most common type of skin cancer and millions are treated each year, only a tiny percentage of these end up causing death in patients. When someone says I would much rather have a basal cell carcinoma than a melanoma, there is a caveat; if you die from a basal cell carcinoma, you are just as dead as if you were to die from melanoma. Happily, most of the time, with early diagnosis and treatment, you don’t have to die from either. Basal cell carcinoma is called cancer for a reason. Give it its respect that it is due, or otherwise, you may regret saying, “oh, you don’t have to worry about it, it’s only a basal cell carcinoma.”
