Laboratory Studies
In angina bullosa hemorrhagica (ABH), platelet counts and coagulation tests are within normal limits.
Procedures
Performing a biopsy of an intact bulla is difficult because of the short duration of the lesion.
Histologic Findings
The diagnosis of angina bullosa hemorrhagica essentially is clinical; however, in the cases in which a biopsy has being taken, the microscopic examination reveals a subepithelial bulla filled with blood and an underlying mild and nonspecific mononuclear inflammatory cell infiltrate that generally is limited to the region of the lamina propria. Occasionally, neutrophils may be seen.[10]
Performing a biopsy of an intact bulla is difficult because of the short duration the lesion stays intact. Otherwise, a biopsy of a ruptured bulla exhibits just a nonspecific ulceration. According to Stephenson et al,[11] direct immunostaining for immunoglobulin G, immunoglobulin A, or C3 consistently are noncontributory.
