Pathological demonstration of varicella infection in first trimester aborted tissue is reported. A 24-year-old primigravida manifested chickenpox infection about 38 days after her last menstrual period or at 24 days age of the embryo. The conceptus survived another 4 to 5 weeks. The macerated embryo and placental tissue revealed nuclear changes consistent with variceIla infection. Immunohistochemical

Varicella zoster virus (VZV), a DNA virus of the herpes virus family, causes chickenpox as a primary infection and herpes zoster when recurrent. An infected pregnant woman can transmit the virus transplacentally to the fetus with consequences of embryopathy a n d / o r abortion. We report a case of transplacental chickenpox in the first trimester with histological definition of infected embryonal and placental tissue. CASE REPORT A 24-year-old gravida 1 para 0 woman was exposed to chickenpox 4 weeks after her last menstrual period. Maternal chickenpox was noted 10 days later at an estimated 24 days of developmental age. At 11 postmenstrnal weeks routine ultrasound examination revealed intrauterine demise. The surgical specimen consisted of fragmented placental tissue and fragments of macerated embryonal tissue. The foot length was 0.6 cm consistent with late embryonal or early fetal age, ie, approximately 8 developmental weeks. Microscopic examination revealed nuclear viral inclusions in autolyzed embryonal tissue (Fig 1). The placenta had acute and chronic vilfitis with glassy appearing nudei suggesting inclusions (Fig 2). Immunohistochemical stains using Cyfimmune VZV rabbit antiserum (Lee Biomolecular Research Laboratory, Inc, San Diego, CA) showed strong reactivity (Fig 3A). There was only minimal reactivity to herpes simplex antiserum and none to cytomegalovirns antiserum. Electron microscopy performed in the placental tissue in the region of the glassy nuclei revealed viral capsids consistent with the herpes group (Fig 3B).

riages and live births in controls and in patients afflicted with varicella during the first 20 weeks of gestation. Inflammatory changes characterized by necrosis, chronic inflammation, and giant cells have been noted in second and third trimester placental a n d / o r fetal tissue by Garcia in 19635 and subsequently by others, eq° Viral-like inclusions were noted in the lungs of a 12-week macerated fetus by Robertson and McKeever, 1° the only previous report of pathological changes in the first trimester.

COMMENT Death in utero within 3 to 5 days after VZV maternal infection was reported at 7 and 8 weeks of gestation in two cases. 1 In a prospective study of 542 mothers infected before 13 postmenstrual weeks, Enders et al noted spontaneous pregnancy loss before 20 weeks in 6% of 501 cases. 2 First trimester maternal varicella infection was associated with first trimester spontaneous abortion in 3 out of 40 cases reported by Balducci et al.~ The losses occurred at 6, 6, and 9 weeks of gestation. Placental examination was nonrevealing in the one case in which it was undertaken. However, in a controlled study, Pastuszak et al 4 found similar proportions of miscar-

FOREIGN BODY HISTIOCYTOSIS REACTION AFTER HIP REPLACEMENT WITH CONCOMITANT METASTATIC ADENOCARCINOMA IN THE SAME LYMPH NODE MICHEL PiOC'H, MD, VERONIQUE DUCROS, MD, RAPHAELLE BARNOUD, MD, DOMINIQUE PASQUIER, MD, MARIE HELENE LAVERRIERE, MD, AND BASILE PASQUIER, MD

Infiltration of regional lymph nodes by macrophages has been shown after total joint arthroplasty. These pelvic lymph nodes were obtained most often from patients during staging procedures for carcinoma and may be a diagnostic pitfall in the frozen section diagnosis of nodal metastasis. We report an mlusual case of association in the same lymph node between histiocytosis and prostatic

carcinoma metastasis. Histiocytosis was caused by wear debris from two different prostheses. Inductively coupled plasma mass spectrometry verified this diagnosis. HUM PATHOL28:95--98.
