Description

Hematoidin crystals are rosette-shaped crystalline aggregates of radially arranged needles measuring from 2 μm to 100μm and stained either yellowish or brownish by the Papanicolaou stain. One to 28 hematoidin crystals are present in one smear.<BR>Hematoidin cyrstals were prospectively searched for from May of 1987 to July of 1988.<BR>Hematoidin crystals were observed in 21 of 100, 403 papanicolaou smears. Inflammatory cell changes were observed in 19 cases and a bloody background was observed in 7 cases out of the 21. Seven cervicovaginal smears were obtained from pregnant and postpartum women among the 21 cases.<BR>Histochemical stains were prepared for 16 of the 21 cases.<BR>The histochemical method used included periodic acidshiff (PAS), Alcian blue stain, iodine stain, Belin blue stain, and an immunohistochemical stain (ferritin).<BR>The PAS stain was positive for hematoidin crystals, but all the other histochemical and immunohistochemical stains were negative.<BR>It was suggested that hematoidin crystal are composed of a protein-carbohydrate complex rather than bilirubin or iron.
