Splenic ectopic pregnancies are a rare cause of abdominal pain in reproductive-age women. A 21-year-old woman with worsening abdominal pain and a positive pregnancy test presented with hemoperitoneum and no intrauterine pregnancy on transvaginal ultrasound. After 2 nondiagnostic laparoscopies, a splenic pregnancy was diagnosed by computed tomography scan and abdominal ultrasound.

We studied at nanometer resolution the viscoelastic properties of microvilli and tethers pulled from myelogenous cells via P-selectin glycoprotein ligand 1 (PSGL-1) and found that in contrast to pure membrane tethers, the viscoelastic properties of microvillus deformations are dependent upon the cell-surface molecule through which load is applied. A laser trap and polymer bead coated with anti-PSGL-1 (KPL-1) were used to apply step loads to microvilli. The lengthening of the microvillus in response to the induced step loads was fitted with a viscoelastic model.
