What is the diagnosis of seborrheic keratosis?
The basis for diagnosis and workup of seborrheic keratosis are generally on their overall appearance. If the tumors are dark, uniform, slow-growing, and have the typical “stuck on” verrucous appearance, there is a high probability that they are benign, and further workup is not necessary. Examination with a dermatoscope would further help differentiate benign features from dysplastic or malignant tumors. Dermatoscope findings for seborrheic keratosis generally show milia cysts, comedo-like openings, fissures, and ridges. Overlapping lesions or high numbers of seborrheic keratosis can make the diagnosis and workup of these lesions more difficult. Patients with high numbers of seborrheic keratoses should receive careful screening, as there can be an increased chance of missing co-existing melanoma or pigmented basal cell carcinoma.
How to treat seborrheic keratosis?
The most common and readily available treatment for seborrheic keratosis would be cryotherapy. [9] This method is efficacious and generally well tolerated by the patient. This method utilizes liquid nitrogen or CO2 to rapidly freeze/thaw the targeted cells, resulting in cell death. There are currently no set guidelines for freezing/thawing times, and they can vary depending on the thickness of the lesion. Thicker lesions may require multiple freeze/thaw cycles to effectively treat the area. Additionally, this treatment method does not permit any histologic confirmation of the lesion and should only be for low-risk, low clinical suspicion for malignancy. This method has a low post-procedure care regimen for the treated area; however, it can cause erythema, pain, and bulla formation. There have been some reported post-procedure hypopigmentation or hyperpigmentation with the healing of these areas after therapy.
