Seborrheic keratoses
Seborrheic keratoses
Cryosurgery is a well-described therapy for seborrheic keratoses. It is critical, however, that the clinical, or preferably histological, diagnosis is confirmed prior to treating with cryotherapy. One study comparing curettage to cryotherapy revealed that 15 of 25 subjects (60%) preferred cryotherapy, while 9 of 25 (36%) preferred curettage. Even though cryotherapy was associated with increased pain, subjects preferred this modality largely due to the decreased requirement for postoperative wound care. Self-reported cosmesis was reported to be the same between the two groups. Physician evaluation showed that there were more redness and tendency for hypopigmentation in the curettage group, and more frequent residual seborrheic
keratoses in the cryotherapy group.18
More recently, a randomized prospective trial of 120 seborrheic keratoses compared cryosurgery to an erbium: YAG laser for treating seborrheic keratoses. Following the first treatment session, 100% of the Er:YAG-treated lesions resolved, while only 63.8% of those treated by cryosurgery completely responded. Both groups received topical anesthesia with EMLA cream prior to treatment, and neither group reported severe pain or interrupted therapy due to pain.19
