Further Outpatient Care
As in patients with chronic solar damage, monitor patients with erythema ab igne at regular intervals for possible development of thermal keratosis, squamous cell carcinoma in situ, and squamous cell carcinoma. In addition, although not yet reported, other cutaneous malignancies (eg, malignant melanoma) feasibly may develop within the affected areas.
Deterrence/Prevention
Reducing or eliminating exposure to the heat source can help prevent erythema ab igne development.
Complications
Malignant degeneration may occur and should be monitored.
Prognosis
The prognosis is good, except those cases associated with internal disease or metastatic malignancy. Early changes, such as erythema and little or no hyperpigmentation, may resolve within several months. Chronic and repeated exposure to heat may result in permanent changes such as hyperpigmentation and atrophy. In addition, thermal keratosis, squamous cell carcinoma in situ, and squamous cell carcinoma have been reported within the lesions of erythema ab igne.
Patient Education
Explain the etiology of the disorder to patients, and emphasize that the cessation of heat exposure is paramount. Inform patients with erythema ab igne about the possibility of malignant degeneration in the affected areas. Educate patients about detection and the need for prompt treatment.
