Melanoma within the seborrheic keratosis.
Seborrheic keratoses (SKs) are common benign nonmelanocytic epidermal tumors with characteristic clinical features, which are thought to allow a straightforward diagnosis in most situations. As a result, it is an accepted practice to destroy them without histopathologic confirmation. However, systematic reviews of histologic specimens reveal an erroneous clinical diagnosis or associated malignant tumors in a number of cases, including malignant melanomas. We describe a patient with a clinically typical-appearing SK, which was biopsied and histologically proven to be a malignant melanoma arising in the SK. Our report is a reminder that the reliability of clinical diagnosis of SKs needs to be questioned. In addition, a biopsy of SKs is not only warranted but necessary in order to identify a malignant melanoma that would otherwise be misdiagnosed or even completely missed.

Epidermolysis bullosa simplex.
Blistering is a common occurrence generally caused by moderate or repetitive trauma to the skin. Blistering due to minor trauma is less common and may be associated with a group of heterogeneous genetic diseases called epidermolysis bullosa (EB). The level of vesiculation within the skin defines 3 major subtypes of EB: EB simplex (EBS), dystrophic EB, and junctional EB. We will review the simple type-EBS.
