Skin cancers are the most common malignancy and are especially common among light-skinned individuals in sun-exposed areas. While in many cases, a characteristic or classic appearance of the lesion is sufficient to make a definitive diagnosis, shave biopsy remains an important procedure when diagnosing many such raised lesions. Over the span of two months, a 66-year-old Caucasian male noted the appearance of a small, raised pruritic scaly lesion over his right upper chest. The differential diagnosis included both cancerous and benign lesions. During a 15-minute clinic visit, a simple shave biopsy was performed, and additionally, 10 small actinic keratoses on the patient's arms, legs, and back were treated with cryotherapy using liquid nitrogen. Later, a histologic examination of the biopsied lesion revealed a benign lichenoid keratosis. The patient was billed $ 10,187 for this outpatient experience.
