    ABSTRACT: The 67th Annual Meeting of the American Academy of Dermatology took place in San Francisco on 6-10 March 2009. The flavour of this busy but well-organized convention was a mixture of practical, hands-on teaching sessions, led and delivered by experts, with breakthrough cutting-edge scientific sessions. Aesthetic dermatology comprised a significant part of the meeting. It is impossible to encompass all the important presentations made at the meeting and satellite symposiums, but we highlight here a few medical pearls on dermoscopy, melanoma and oncology, inflammatory dermatoses and community-acquired methicillin-resistant Staphylococcus aureus. Our report is not intended as a substitute for reading the conference proceedings, educational session handouts, online updates and related references quoted in this article.

    ABSTRACT: B-cell-activating factor belonging to the tumour necrosis factor family (BAFF) is known for its role in the survival and maturation of B cells. It has been recently suggested that BAFF also plays important roles in T-cell activation in T-cell mediated diseases such as psoriasis. To investigate the role of BAFF in cutaneous T-cell lymphoma (CTCL). BAFF messenger RNA (mRNA) expression in skin samples (24 CTCL cases and seven healthy controls) and in skin-derived fibroblasts (five CTCL cases and five healthy controls) was examined by quantitative reverse transcription-polymerase chain reaction. We also performed immunohistochemical staining for BAFF and its receptors. Serum BAFF levels were measured in patients with CTCL (n=46), atopic dermatitis (n=36) or psoriasis (n=27) and 27 healthy controls by enzyme-linked immunosorbent assay. Lesional skin of CTCL contained higher levels of BAFF mRNA than normal skin and the expression levels correlated with disease activity. BAFF mRNA expression levels were elevated in fibroblasts from CTCL skin. Tumour cells in the lesional skin of CTCL expressed BAFF and its receptors, while fibroblasts expressed only BAFF. Serum BAFF levels of CTCL patients were significantly higher than those of healthy controls and correlated with types of skin lesions and clinical stages. They also significantly correlated with serum soluble interleukin-2 receptor and lactate dehydrogenase levels. BAFF expression in CTCL skin and serum BAFF levels are significantly increased and correlate with the severity of CTCL. These results suggest that BAFF may have important roles in the development of CTCL.
