A 60-year-old man comes to the office because of a lesion on his lower lip that has been growing for the past 9 months. It is painless and he is now here because his wife made him come. He has not seen a physician for the past 4 years. He works as a farmer and is exposed to the sun. On physical examination, the lower lip is fixed to the lower aspect of the mandible. Which of the following is the correct diagnosis?
A. Basal cell carcinoma
B. Erythema nodosum
C. Leukoplakia
D. Melanoma
E. Squamous cell carcinoma

I thought so too, but the answer turned out to be something else!!!
The correct answer is A. Basal cell carcinoma is the most common form of skin cancer and risk factors include sun exposure and ultraviolet radiation. Features include an ulcerated center with pearly, heaped up edges. Excision may be required.
Erythema nodosum (choice B) is a vascular disorder whose skin manifestations include erythematous and nodular lesions, especially on the anterior aspect of the tibia.
Leukoplakia (choice C) is an Epstein-Barr virus-related lesion that would be found on the lateral aspects of the tongue and is white in appearance.
Melanoma (choice D) has the maximum metastatic potential and may be nodular or radial. It may have irregular borders, may be of variegated coloration, and may be on any aspect of the body.
Squamous cell carcinoma (choice E) is the second most common form of skin cancer after basal cell carcinoma and would be most common on sun-exposed surfaces as well.
