Résumé
Syringocystadenoma papilliferum (SP) is a benign tumor most commonly located on the scalp or face, which frequently arises from a nevus sebaceus (NS). Transition of SP to basal cell carcinoma (BCC) and, albeit rarely, to metastatic adenocarcinoma may occur. Allelic deletions of the human homologue of the drosophila patched gene (PTCH) occur in both NS and BCC. To search for genetic changes in SP, a microdissection-based genetic analysis using polymorphic markers at 9q22 (PTCH; D9S15, D9S303, D9S287, D9S252) as well as markers at 9p21 flanking the tumor suppressor gene p16 (IFNA, D9S171) was performed. Glandular epithelium consisting of two rows of cells as well as adjacent normal tissue or inflammatory infiltrates in the stroma, when present, was dissected and subjected to single-step DNA extraction and loss of heterozygosity (LOH) analysis. Two of 10 informative SP cases showed LOH at 9q22 (PTCH). Three of 7 informative SP cases showed allelic deletions at 9p21 (p16). Allelic loss at 9q22 is consistent with the clinical observation of transition of SP to BCC. The finding of frequent allelic loss at 9p21 is unlikely to be related to the rare transition of SP to metastatic adenocarcinoma. Our study supports the hypothesis of a gatekeeper role of the tumor suppressor gene p16 in a variety of benign and malignant tumors, including SP.
