If a Chronic Wound Does Not Heal, Biopsy It: A Clinical Lesson on Underlying Malignancies

Infection is another possible explanation of a nonhealing wound. On the face, an underlying dental abscess with a sinus tracking from the root of the tooth to the skin of the cheek or jaw may be the source. Elsewhere on the body, chronic osteomyelitis may be the cause, which may be from any infective origin from Staphylococcus aureus to tuberculosis, and will most commonly present with a discharging sinus but also may present with a nonspecific ulcer.

Chronic wounds also may not heal because of a multitude of patient factors such as poor nutrition, diabetes mellitus, medication (eg, steroids, nonsteroidal anti-inflammatory drugs), other inflammatory causes, and poor mobility. Chronic wounds represent a substantial burden to patients, health care professionals, and the health care system. In the United States alone, they affect 5.7 million patients and cost an estimated $20 billion.¹ Approximately 1% of the Western population will present with leg ulceration at some point in their lives.²

Physical examination of ulcers in any clinical setting can be difficult. We postulate that it can be made more difficult at times in primary care because the patient may add confounding elements for consideration or seemingly plausible explanations. However, whenever possible, a physician should ask, “Could there possibly be an underlying malignancy here?” If there is any chance of malignancy despite plausible explanations being offered, the lesion should be biopsied.
