Is keratoacanthoma a squamous cell carcinoma?

Keratoacanthoma (KA) is a relatively common low-grade tumor that originates in the pilosebaceous glands and closely resembles squamous cell carcinoma (SCC). In fact, strong arguments support classifying keratoacanthoma as a variant of invasive SCC.

How can you tell the difference between squamous cell carcinoma and Keratoacanthoma?

Keratoacanthoma is typically a self-healing, rapid onset skin lesion, with a dome-shaped keratin-filled crater, whereas cutaneous squamous cell carcinoma is conventionally a malignant lesion with cellular atypia and stromal invasion that progresses continuously without spontaneous resolution.

How quickly should a keratoacanthoma be removed?

Treatments Your Physician May Prescribe If left untreated, most keratoacanthoma spontaneously disappear (resolve) within 6 months, leaving a depressed scar. However, they may cause significant damage to the skin and underlying layers of tissue as well as psychological distress.

How are retinoidlike agents used to treat keratoacanthomas?

Retinoidlike agents are efficacious in the treatment of keratoacanthomas with good cosmetic outcome. [ 36] These agents are useful in patients with large or multiple tumors or tumors that are inoperable because of anatomic location or the patient’s poor medical status. They also are useful for eruptive keratoacanthomas of the lower legs.

How does a doctor know if you have keratoacanthoma?

The cells of keratoacanthoma often look just like those of squamous cell carcinoma.
