Pseudomembranous conjunctivitis following bone marrow transplantation: immunopathological and ultrastructural study of one case

Human Pathology
A JaninB Gosselin

Abstract

Pseudomembranous conjunctivitis (PMC) is a rare ophthalmic lesion usually caused by infectious agents such as streptococcus, Klebsiella, Chlamydia, or adenovirus. It can also be associated with skin lesions of toxic epidermal necrolysis (TEN) and graft-versus-host-disease (GVHD). We report the pathological study of a patient with PMC and GVHD who had a conjunctival biopsy before death. This allowed us to differentiate this form of PMC from PMC of infectious origin, and to find within the epithelium characteristic features of acute GVHD and mononuclear cells expressing natural-killer markers. This suggests that this form of PMC resulted from a very acute, cytotoxic form of GVHD. Because PMC in bone marrow recipients can be related to infections, TEN, or acute GVHD, a systematic pathological study is required to guide the therapy.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
