Phenytoin hypersensitivity syndrome (PHS) is a
rare delayed hypersensitivity reaction which oc¬
curs following exposure to phenytoin sodium. Pul¬
monary involvement is uncommonly described.
Herein is reported the first case of histopathologic
bronchiolitis obliterans organizing pneumonia
(BOOP) found on open-lung biopsy in a patient
with severe PHS. New onset, clinically significant,
cold agglutinin disease was also documented. He¬
modynamic parameters mimicking sepsis were
present in the absence of significant clinical infec¬
tion. Rapid, dramatic improvement followed highdose steroid therapy.

Case Report
1994, a 40-year-old black
man
underwent
craniotomy and started receiving therapy with phenytoin sodium
(Dilantin; Parke-Davis; Morris Plains, NJ), 300 mg daily. A
medical history revealed chronic use of tobacco, crack cocaine,
and alcohol. Results of a lung examination and a chest x-ray film
showed no abnormalities. Four weeks following phenytoin ther¬
apy, clear rhinorrhea, myalgia, high fever, diffusely spreading
pruritic maculopapular rash, and dry cough developed. The
cough became productive and was associated with dyspnea.
Six weeks after phenytoin therapy was initiated, the patient was
readmitted to the hospital. Vital signs were as follows: respiratory
rate, 24 breaths per minute; heart rate, 112 beats per minute; BP,
100/60 mm Hg; and temperature, 38°C. Examination revealed
diffuse skin exfoliation; conjunctivitis; facial edema; tender, en¬
larged lymph nodes; decreased breath sounds bilaterally with
diffuse inspiratoiy crackles; mild right upper quadrant tender¬
ness; and hepatomegaly.
Laboratory7 findings included a fall in hemoglobin level from
155 g/L (noted 6 weeks earlier prior to phenytoin treatment) to
133 g/L; WBC count, 29X109/L (35% eosinophils); subtherapeu-
phenytoin level; mildly elevated liver function tests; while
breathing room air, arterial blood gas values showed mild
hypoxia; and chest radiograph, diffuse, patchy, asymmetric, reticulonodular infiltrates. Administration of broad-spectrum anti¬
biotics and prednisone, 50 mg daily, was started. Phenytoin
treatment was discontinued. Tests for cold agglutinins were
positive. The Mantoux test and tests for HIV, heterophile
agglutination, antinuclear antibody, rheumatoid factor, Legio¬
nella, and sputum cultures for bacteria, fungi, acid-fast bacilli,
and Pneumocystis carinii pneumonia were negative. A skin
biopsy specimen showed a drug eruption. Serological tests for
Mycoplasma, adenovirus, influenza A and B, herpes simplex,
cytomegalovirus, and hepatitis A, B, and C were negative. Spiking
fevers, marked eosinophilia, and deterioration of liver function
tests continued (aspartate aminotransferase, 214 U/L [normal,
<40 U/L]; alanine aminotransferase, 247 U/L [normal, <35
U/L]; lactate dehydrogenase, 435 U/L [normal, <260 U/L];
alkaline phosphatase, 237 U/L [normal, <35 to 125 U/L]). The
admission hemoglobin level of 133 g/L dropped to 101 g/L within
48 h of hospitalization, and a mild coagulopathy developed.
Respiratory7 insufficiency culminated in ICU admission and intu¬
bation. A chest x-ray film revealed asymmetric patchy infiltrates
at lung bases (Fig 1). Sepsis-like hemodynamics developed with
hypotension; tachycardia (heart rate, 120 to 140 beats per
minute); cardiac output, 10 to 17.5 L/min; and systemic vascular
resistance, 300 to 500 dyne-s*cm~5 (normal, 770 to 1,500 dyneS'cm-5) requiring inotropic and fluid support. Bronchoscopy,
BAL stains, cultures, and cytologic studies were negative for
organisms. Urine was treated for a Staphylococcus aureus infec¬
tion. All other cultures
tic
remained negative for organisms.

and 1:4 at 30°C; with albumin, the titer was 1:8 at 30°C. Nucleated
RBCs, occasional cell fragments and spherocytes, and 1 to 2%
atypical lymphocytes were found on a smear. Transfusion of packed
RBCs following crossmatch by prewarm technique failed to show
the appropriate rise in hemoglobin and was followed by further
transfusion. The coagulopathy worsened (prothrombin time, 20 s;
partial thromboplastin time, 35 s; international normalized ratio, 3.0)
and was unresponsive to vitamin K, but did improve following
administration of fresh-frozen plasma. Factor analysis showed hep¬
atocellular injury.
An open-lung biopsy specimen showed myxoid organizing
granulation tissue present in bronchioles,inwhich was consistent
with BOOP (Fig 2, top). A mild increase eosinophils within a
chronic mononuclear inflammatory infiltrate was present in the
alveolar exudate (Fig 2, bottom). Lung tissue was negative for
acid-fast bacilli, fungi, P carinii pneumonia, vasculitis, or granu¬
lomata. Electron microscopy was negative for viral inclusions.
BAL culture later grew rhinovirus. Methylprednisolone sodium
succinate (Solu-Medrol), 60 mg, was administered intravenously
every 6 h for 48 h and then followed by a slow intravenous taper
over 1 week. This was followed by high-dose treatment with
prednisone (1 mg/kg) for 3 months, followed by a very slow taper
for a total steroid course of 1 year. Pulmonar)7 function tests done
10, 21, and 42 days after steroid administration showed a
resolving restrictive lung defect and reduced diffusing capacity of
carbon monoxide. A chest x-ray film, liver function, and all
hematologic abnormalities resolved.

mononuclear, patchy, and thought to be part of the lung's
reparative process after insults, including hypersensitivity
reactions. Commonly, BOOP is sensitive to steroid therapy,2
associated with a restrictive lung defect and decreased carbon
monoxide diffusing capacity7. X-ray film findings vary and
often show multiple, patchy interstitial-alveolar infiltrates like
those described here. Use of crack cocaine, implicated in one
case of BOOP,3 was not thought significant here since this
patient ceased cocaine use after his first hospital discharge
and clearly suffered from a generalized hypersensitivity syn¬
drome, a finding not associated with cocaine.
Rhinovirus found on BAL culture was likely the result of
upper airway contamination during bronchoscopy. The clear
rhinorrhea at illness onset, multiple other case reports sug¬
gesting concomitant respiratory tract infections, and the
reported seasonal variation of phenytoin hypersensitivity7
reactions4 suggest a role for concurrent infection in triggering
or intensifying the syndrome or, conversely, infections may
be the result of phenytoin's effect on immune function.
Sepsis-like hemodynamics, responsive to steroids, have been
described rarely in PHS.5
Coombs'-negative hemolytic anemia has been repeat¬
edly noted in PHS. Coombs'-positive hemolysis, however,
was mentioned only once in the present review of the
literature.6 Here is provided the first full description of
