ABSTRACT
Cryotherapy is a simple, relatively inexpensive therapeutic modality that is widely-used in clinical practice. It is especially appropriate for patients with an intolerance to anesthesia as well as high risk factors for developing hypertrophic scars after surgery. It can be applied to skin lesions located close to vital structures such as vessels and nerves. Potential side effects include pain, hemorrhage, edema, blisters, infection, hypopigmentation, and sensory damage. There are a numerous reports in the literature describing the side effects of cryotherapy. However, cases with severe complications have rarely been reported as yet. Herein, we report a case of serious complications of cryotherapy, a result of the course of treatment for linear porokeratosis.

Porokeratosis is a group of genetic diseases characterized by clonal proliferation of keratinocytes. We report a 16-year-old female who presented with both linear porokeratosis and disseminated superficial actinic porokeratosis. The unusual coexistence of these two types of porokeratosis is an example of a type 2 segmental manifestation of an autosomal dominant skin disorder.

Porokeratosis is a genodermatosis that is characterized by abnormal epidermal keratinization with the histologic finding of a cornoid lamella. Linear porokeratosis is an uncommon variant that presents a characteristic linear nevoid distribution along the Blaschko's lines and linear porokeratosis has the highest potential for malignant degeneration of all the porokeratoses. Many treatment modalities have been used, but the treatment outcomes are variable and the treatments are poorly standardized. We report here on a case of linear porokeratosis in a 48-year-old female who showed localized, linear, brownish macules with a well-demarcated hyperkeratotic border on the left lower abdomen and back.

Porokeratosis are characterized by distinct clinical findings of a keratotic ridge that corresponds to the cornoid lamella on histology and has well defined potential for malignancy. We report a case of basal cell carcinoma(BCC) arising in linear porokeratosis in a 77-yearold man.
