Basic Data

• The 44 y/o female patient visited our ER on 2002/04/01 due to refractory diffuse oral and pharyngeal ulcer for about 8 days.

• Besides, she had productive cough for about 1 month and conjunctivitis (LMD & herb medicine)

• Under the impression of Steven-Johnson syndrome related to HSV infection or drug, she was admitted to 15A ward for further care.

Brief History and Admission Course (I)

Brief History and Admission Course (II)

• Physical examination General appearance: ill-looking Consciousness: clear Conjunctiva: injected Sclera: anicteric Oral mucosa: diffuse erosion with yellowish crust

over the whole buccal and lingual mucosal surface

Brief History and Admission Course (III)

• 4/2 : admission and start IV steroid treatment; skin biopsy

was done

• 4/8 : Skin biopsy result (lower lip) : suprabasilar blister with

sloughed epidermis, pemphigus was likely

Fever was noted─ suspect UTI related

Empiric antibiotics were used

• 4/13 : DC steroid due to poor infection control

Brief History and Admission Course (IV)

• 4/14 : Skin biopsy (Back) : suprabasilar acantholysis with blister formation Direct immunofluoresence stain : linear C3 deposition at basement membrane zone IgG at intercellular space of epithelium check tumor marker: CA125(202.64)↑ Highly suspect paraneoplastic pemphigus• 4/15 : Abd. sonography : splenomegaly with hypoechoic lesion, susp. tumor infiltration (Lymphoma) No pelvic mass was noted

Brief History and Admission Course (V)

• 4/16 : Abd. CT :

1.Huge hypodense splenic tumor of 13x11x18 cm

2.Hypodense mass at the pelvis with ascites

3.1.2 cm hypodense lesion at liver

Imp: 1.Uterine tumor with spleen and liver metastasis

2.Non-Hodgkin’s lymphoma

Brief History and Admission Course (VI) Biopsy of the splenic tumor was unfeasible due to high hemorrhagic

risk→ diagnostic laparoscopic splenectomy was suggested Solumedrol 40mg q12h iv was used to control her pemphigus

activity

• 4/18 : consult infection specialist for poor control of infection intraperitoneal TB was suspected• 4/22 : fever subsided after four combined anti-TB therapy (Isoniazid, Rifampin, Pyrazinamide and Ethambutal). • 4/23 : scheduled for op but was postponed due to difficult intubation risk • 5/13 : operation

Post-operative Course

• Profound new vesicles were found when she was transferred back to the ward and the Solu-medrol was increased to 240mg per day. New vesicles stopped in 5 days and old ones healed almost completely.

Solu-medrol was tapered to 80mg per day after new vesicles stopped formation.

Paraneoplastic Pemphigus

• Autoimmune disease that accompanies an overt or occult neoplasm and cause blisters

• The most commonly associated neoplasms: -- Non-Hodgkin’s lymphoma -- Chronic lymphocytic leukemia -- Castleman’s disease -- Thymoma -- Retroperitoneal scarcoma -- Waldenstrom’s macroglobulinemia

International Journal of Dermatology 2001,40:367-72

Lancet 1999, 354:667-72

Clinical Manifestations

• Mucosal: intractable stomatitis causing erosions and ulcerations in the oral mucosa

• Cutaneous: trunk and proximal extremities flaccid or tense blisters with or without erosions

• Respiratory: obstructive ventilatory defect inflammation, vesiculation of tracheobronchial epi.

Immunologic Studies

• Immunoprecipitation studies: gold standard for the diagnosis of paraneoplastic pemphigus

• Respiratory and urinary bladder epi: desmoplakin(+), desmoglein(-) for distinguishing paraneoplastic pemphigus from other forms of pemphigus

Pathogenesis

• Combination of humoral and cell-mediated autoimmunity

• Neoplasm of immune origin may cause dysregulation of immune system

• Antigenic components that cross-react with epidermal cell surface proteins

Diagnosis

Respiratory Failure in Paraneoplastic Pemphigus

• Bronchiolitis obliterans • Infection, toxic effects induced by chemotherapy,

neoplasia and autoantibody-mediated pulmonary injury

• Acantholysis with deposits of IgG in the bronchial epithelium.

• Antiplakin antibodiesNEJM 1999; 340(18): 1406-10, 1999

Case 1

• 46 y/o female• Abdominal hysterctomy and bilateral salphingo-

oophorectomy• Pemphigus vulgaris for 8 years• Prednisone 10mg + azathioprine 100mg• PE: painful bullous formations in the mouth and

oropharynx

Regional anaesthesia in pemphigus vulgaris. Anaesthesia, 1992; 47:74

Process and Results

• Spinal anesthesia• Hydrocortisone 100mg iv. preoperative and

during surgery• 25-gauge spinal needle inserted at the L2-3• No lesions at the site of spinal needle puncture,

blood pressure cuff, intravenous cannulation, or oxygen mask application (the face has been pretreated with vaseline gel)

Case 2

• 45 y/o man• Exploratory laparotomy for suspected PPU• Pemphigus vulgaris with bullae over face, trunk,

extremities, oral cavity and pharynx• Prednisolone 60mg/day + NSAID

Anaesthetic management of a patient with pemphigus vulgaris for emergency laparotomy. Anaesthesia 2000; 55:155-162

Process and Results

• General anesthesia• Monitors: CVP, A-line, pulse oximetry, end-tital gas

monitoring• Facial lesions were covered with 1% hydrocortisone cream

and soft cotton sponges before placing the facemask• Pre-OP laryngoscope: bleeding from mucosal lesion of

oropharynx throat pack soaked with saline adrenaline• Induction: thiopental + succinylcholine• Maintenance: NO 66% + halothane 0.5% in oxygen• Extubation under deep halothane anesthesia• Hydrocortisone pre-operative and post-operative

Case 3

• 49 y/o female, Stage IV vulvar carcinoma• Radical vulvectomy and bil. femoral and pelvic node

disection• Bullous pemphigoid diagnosed 2 months before• Admitted for iv steroid administration and hydration

before surgery due to poor control• Prednisone 80mg + azathioprine 50mg bid• PE: ulcerated lesion on the lower gums, no intraoral

lesionsAnesthetic management of a patient with bullous pemphigoid.

Anesth Analg 1989; 69:537-40

Process and Results

• Spinal anesthesia

• Premedicated with morphine, scopolamine and hydrocortisone

• Adhesive tape, the IV catheter, precordial stethoscope, ECG pads and blood pressure cuff as usual

• New bullous and erythematous lesions of the face and inframammary area

• No lesions at the site of spinal needle puncture, blood pressure cuff placement, or IV cannulation

• No lesions at pressure points

Discussion

• New bullae formation

• Infection and dehydration

• Side effects of medication

• Choice of anesthesia

• Endotracheal intubation

New Bullae Formation

• Prevention of :

-- friction and trauma

-- local anesthesia infiltration

-- spirit swab

-- adhesive tape

-- ECG electrodes and blood pressure cuff

Infection and Dehydration

• Fluid replacement for dehydration

• Correct electrolyte abnormalies

• The choice of injection site should be away from skin lesion

Side Effects of Medication

• Steroid

-- sodium and fluid retention, hypokalemic alkalosis,

peptic ulcer, hyperglycemia, impaired wound healing

• Azathioprine

-- reversible leukopenia and thrombocytopenia, secondary to bone-marrow supression, and hepatotoxicity with biliary stasis

Choice of Anesthesia

• Controversial• Ketamine• 131 patients, ETGA

-- no intraoperative or postoperative airway

obstruction

-- 6 instances of facial and intraoral bullae

formation

Endotracheal Intubation

• ET tube should be liberally lubricated

• Face and lips should be pretreated with 1%hydrocortisone cream and vaseline gel

• Maintaining minimal cuff inflation pressure

• Macintosh rather than a Miller laryngoscope blade

• Smaller tube

• ET tube should be secured with a soft cloth bandage

• Postoperative laryngoscope?

In Our Patient

• Potential of more generalized involvement

• Avoid of adhesive tape

• Avoid of ECG electrodes and blood pressure cuff if possible

• Pretreatment of face and lip

• Smaller ET tube
