Solve the Medical Riddle: She Has Blisters in Her Mouth and on Her Body, Second Week

Editor’s note: Welcome to our ThirdAge feature that gives you a chance to play medical sleuth as we share the details of what happened when a patient presented with a problem that stumped the physician at first.

Last week, the patient reported her symptoms. The doctor proceeded with the examination using the components of the classic S-O-A-P notes, which are as follows:

S=Symptoms or Chief Complaint

O=Objective Findings

A=Assessment or Analysis

P=Treatment Plan or Recommendations

The doctor suspectedthat Zoe has a systemic blistering lesion condition that was not likely to be drug-related. He ordered blood work and referred Zoe to a dermatologist associated with a university..

The dermatologist reviewedher history, physical exam, and the results of the blood tests and performed the following additional tests:

Skin Biopsy: Histopathology (a biopsy and look under a microscope) from the edge of a blister.                         

Direct immunofluorescence (DIF)on normal-appearing perilesional (area around the erosion) skin. When DIF testing is performed on lesional skin, false-positive results can be observed, so a biopsy and DIF of skin surrounding the lesion is important.

Blood Test: Indirect immunofluorescence (IDIF)using the patient’s serum if DIF results are positive. IDIF demonstrates the presence of circulating IgG autoantibodies that bind to theepidermis.

To be continued . . .

Come back to ThirdAge.com next Thursday to find out what some people have guessed the diagnosis might be.
