Quiz 12 Context:
A 44-year-old man presents for an emergency room follow-up appointment. He presented to the emergency room after falling from a ladder and sustaining a leg contusion. He is otherwise healthy and has not sought routine medical care. He is a non-smoker and consumes one alcoholic beverage per day. He works as a landscaper.
Physical examination reveals the contusion is healing well. However, an asymptomatic skin lesion is noted at the left nasofacial sulcus. The lesion is a small papule with associated telangiectasia. Within the lesion, there is a very small central area with crusting.
The skin
finding is pictured above.
Sorry, that is not the most likely answer. Try Again.
c. Excellent!
This image reveals basal cell carcinoma. Basal cell carcinoma is frequently found on the head and neck. The lesions are typically described as pearly, dome-shaped nodules with a central depression or ulceration and rolled borders containing blood vessels. In fact, basal cell carcinoma has five different clinicopathologic subtypes: nodular-ulcerative, superficial, pigmented, morpheaform (sclerosing) and basosquamous.
You have correctly identified this week's Image of the Week. Now test your knowledge of other aspects of non-melanoma skin cancers. Do you know…
…the magnitude of the reduction in the incidence of non-melanoma skin cancer predicted with the regular use of protective sunscreen and the ages and sun protective factor (SPF) involved in this prediction?
…the two syndromes that include multiple basal cell carcinomas as a feature of the syndrome and the inheritance pattern of each?
…the correct biopsy technique to use for the diagnosis of basal cell carcinoma based upon which clinicopathologic subtype is suspected?
The answers to these questions and a concise review of the pathogenesis, diagnosis, and treatment of non-melanoma skin cancers can be found here within the Disease Management Project.
This
is most consistent with which of the following?
- Erythema multiforme (targetoid papule)
- Seborrheic dermatitis
- Basal cell carcinoma
- Squamous cell carcinoma
- Allergic
contact dermatitis
