Conclusion
We report of a case of linear porokeratosis with associated multiple SCCs that developed within the lesion. Definitive diagnosis of linear porokeratosis is important due to the higher rate of malignant transformation than the rate seen in other porokeratoses. In larger lesions, appropriate sampling and orientation of the pathology specimen is essential for identifying cornoid lamellae, thus allowing for appropriate follow-up and management. Several treatment options are available, though evidence for the effectiveness of any particular therapy is lacking. Research has shed light on possible genetic and molecular abnormalities in linear porokeratosis, but the exact pathogenesis of the disorder remains unclear.
