Comment On Dermoscopic Features of Seborrheic Keratoses Following Cryotherapy
Seborrheic keratosis (SK) is the most common benign tumor in older individuals.
Freezing with liquid nitrogen has been widely used as a method of
treatment. In one of our patients treated with cryotherapy, follow-up dermoscopical
image of the lesion raised a concern for regressing malignant
lesion in the post treatment period. Information on the dermoscopy of SK
treated with cryotherapy was not available. Consequently, we gathered and
retrospectively analysed the pictures taken during healing periods of four
SK without choosing a specific type. Besides dermoscopic structures specific
for SK, coarse and fine gray granules arranged in a linear or annular pattern
were also noted. These features have been reported in various malignant
tumors before. Most of the time, clinical diagnosis of SK is not an issue;
although rarely though rare malignant transformation of SK has been reported.
Furthermore, SK may be found with another malignant condition
as a collision tumor. Consequently, we think all the dermoscopic features
presented are compatible with cryotherapy induced lichenoid keratosis like
lesions. As a conclusion, it is important to know and document the dermoscopic
findings that occur in the post-cryotherapy healing period to prevent
an impression of misdiagnosis or inadequeate therapy
