Laboratory Studies
- Perform laboratory studies based on clinical suspicion or history that may help to establish the primary cause of exfoliative dermatitis. Other laboratory studies include the following:
- Evaluation for cardiac failure and renal and intestinal dysfunction
- CBC with differential, liver enzymes level, creatinine level, and urinalysis
- Serum albumin level
- Erythrocyte sedimentation rate (ESR)
- The most common laboratory abnormalities are anemia, hypoalbuminemia, eosinophilia, and an elevated sedimentation rate.
Imaging Studies
- Obtain imaging studies based on suspicion of underlying systemic disease or when other causes are excluded.
Procedures
- Biopsy
- Perform skin biopsy and lymph node biopsy if significant lymphadenopathy is noted.
- Histologic findings generally are nonspecific and include hyperkeratosis, parakeratosis, acanthosis of the epidermis, and perivascular infiltrate consisting of histocytes, lymphocytes, and some eosinophils.
