The association between severe long-term atopic dermatitis (AD) and the risk of skin lymphoma is still a matter of debate, since epidemiological studies have shown contradictory results. We report 2 cases of patients with a documented history of severe longstanding atopic disease, who had never been treated with topical or systemic calcineurin inhibitors, and who developed a cytotoxic cutaneous T cell lymphoma (CTCL). For these 2 patients, clinical manifestations preceded the diagnosis of CTCL. The diagnosis was based on histological findings and molecular analysis of the T cell receptor (TCR) clonality. These cases illustrate the difficulty in diagnosing CTCL in patients with severe AD and extensive inflammatory skin lesions. The transition between severe AD and CTCL is progressive; histological findings and molecular evidence of TCR clonality are detected after the clinical changes. These 2 cases lend further support to the hypothesis of an association between severe long-term AD and CTCL.

What is Visualize?
JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.
How does it work?
We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.
Video X seems to be unrelated to Abstract Y...
In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
