Angiomyxoma of the nasal dorsum treated by Mohs surgery.

Cutaneous angiomyxomas are myofibroblastic neoplasms with locally aggressive behaviour and a high risk of recurrence. We describe a case of a solitary cutaneous angiomyxoma presenting on the nasal dorsum of a 28-year-old man, excised with Mohs surgery using permanent section control and repaired with an advancement flap. Histology showed myxoid nests of bland CD34-positive and vimentin-positive stellate and spindled cells in the deep dermis and abundant thin-walled blood vessels.

Quantitative methylation-specific PCR for the detection of aberrant DNA methylation in liquid-based Pap tests.

Background: Aberrant promoter methylation of selective tumor suppressor genes has been detected in squamous intraepithelial lesions (SIL) and invasive cervical cancer. Identification of methylation profiles of genes that can distinguish high-grade SIL (HSIL) from low-grade SIL (LSIL), and cytologically negative for intraepithelial lesion or malignancy (NILM) residual liquid-based Papanicolaou (Pap) tests may be potentially useful as an ancillary test for cervical cancer screening.

Methods: Using real-time quantitative methylation-specific polymerase chain reaction (PCR) (QMSP), the authors analyzed the frequency and relative level of promoter methylation for DAPK1, IGSF4, SPARC, and TFPI2 in biopsy-confirmed HSIL and LSIL, and NILM residual liquid-based Pap tests.
