Histologic diagnosis and differential diagnosis of cutaneous diseases
When this test is ordered, 1 of the 3 reflex tests will be performed and charged. Appropriate additional stains and other ancillary testing may be performed to determine a diagnosis. These stains and tests will be charged separately.
See Pathology Consultation Ordering Algorithm in Special Instructions.
Dermatopathology involves histologic examination of skin biopsy and oral mucosal specimens.
Diagnosis and description of microscopic findings
Histologic diagnosis is based primarily on interpretation of hematoxylin and eosin-stained sections. Special histochemical stains, such as alcian blue, Giemsa, or periodic acid-Schiff may be necessary in some cases.
Interpretation is based on evaluation of patterns including architectural and cytologic details, which are included in a microscopic description.
Specific diagnosis may require correlation with clinical information.
