Definition / general
- Graft versus host disease (GVHD) is a serious complication observed following approximately 40 - 60% of allogeneic hematopoietic stem cell transplants but rarely after transfusions or solid organ transplants (An Bras Dermatol 2016;91:336, Cancer 2004;101:1936, Blood 2012;119:296)
Essential features
- GVHD most commonly occurs after allogeneic hematopoietic stem cell transplantation
- Dyskeratotic keratinocytes involving the adnexal epithelium can differentiate between GVHD and drug eruption in difficult cases
- GVHD and drug reactions cannot always be distinguished on histologic grounds; therefore, strong clinical correlation is essential in all cases
Terminology
- GVHD: graft versus host disease
- GVH: graft versus host reaction or disease
ICD coding
Epidemiology
- Occurs in 40 - 60% of allogenic hematopoietic stem cell transplant recipients (An Bras Dermatol 2016;91:336)
- Occurs in up to 40% of HLA identical and up to 70% of HLA mismatched hematopoietic stem cell transplant recipients (Cancer 2004;101:1936, Blood 2012;119:296)
- 64.3% of solid organ transplant GVHD occurred after liver transplantation (J Am Acad Dermatol 2018;78:1097)
Sites
- Lesions usually start on the pinnae and neck and progress to confluent lesions on the cheeks, upper trunk, palms and soles, which may become generalized (J Invest Dermatol 1985;85:124s)
- Extremities in 15.8%, the trunk in 13.9% and the face in 8.9% (J Am Acad Dermatol 2018;78:1097)
Pathophysiology
- 3 phases of acute GVHD (Biol Blood Marrow Transplant 1999;5:347):
- Phase 1: damage to host tissues by inflammation from the preparative chemo or radiotherapy regimen
- Phase 2: recipient and donor antigen presenting cells as well as inflammatory cytokines triggering the activation of donor derived T cells, which expand and differentiate into effector cells
- Phase 3: activated donor T cells mediate cytotoxicity against target host cells through Fas-Fas ligand interactions, perforin-granzyme B and the additional production of cytokines, such as TNFα
- TNFα is produced mainly by monocytes and macrophages and secondarily by T lymphocytes and natural killer cells
Clinical features
- Revised National Institute of Health (NIH) criteria now define classic acute GVHD as occurring within 100 days following hematopoietic stem cell transplantation (Br J Haematol 2012;158:30)
- Late onset acute GVHD occurs after 100 days and affects mainly the skin, gastrointestinal tract and liver (Br J Haematol 2012;158:30)
- Chronic GVHD occurs 100 days after hematopoietic stem cell transplantation, representing 50% of all cases and causing late mortality in up to 25% of patients (An Bras Dermatol 2016;91:336)
- Clinical manifestations of GVHD after hematopoietic stem cell transplantation include fever, cutaneous rash, severe gastrointestinal manifestations and impaired liver function (An Bras Dermatol 2016;91:336)
- Cutaneous GVHD manifests as erythematous maculopapular rash that can begin anywhere in the body but often starts with palm and sole involvement (An Bras Dermatol 2016;91:336)
- Early lesions are usually centered on a hair follicle, a clue for diagnosis (Arch Dermatol 1988;124:688)
- If the rash is severe, vesicles, bullae and erythroderma can develop; generalized desquamation also emerges (Adv Dermatol 2001;17:115)
- Lichenoid chronic GVHD patients present with violaceous or erythematous papules and plaques, including a fine scale on top that can coalesce (An Bras Dermatol 2016;91:336)
Prognostic factors
- Associated with lower survival for acute GVHD:
- Advanced disease status (Bone Marrow Transplant 2013;48:587)
- Increasing age of patients (Bone Marrow Transplant 2013;48:587)
- Associated with higher survival for acute GVHD:
- Late onset (Bone Marrow Transplant 2013;48:587)
- Involving skin only (Bone Marrow Transplant 2013;48:587)
- Associated with lower survival for chronic GVHD:
- Low platelet counts < 100,000/μl at the time of diagnosis (Ann Hematol 2015;94:1727)
- Female donor (Ann Hematol 2015;94:1727)
- IgG levels above normal at the time of diagnosis (Ann Hematol 2015;94:1727)
- No impact of prior acute GVHD on outcome of patients with chronic GVHD (Ann Hematol 2015;94:1727)
Case reports
- 6 year old boy with squamous cell cancer in situ in the setting of sclerodermatous GVHD and voriconazole treatment (Pediatr Dermatol 2018;35:e165)
- 8 year old boy with vitiligo type cutaneous manifestation of chronic GVHD (Rev Chil Pediatr 2018;89:113)
- 35 year old man with cutaneous sclerodermatous GVHD resembling nodular / keloidal scleroderma (Am J Dermatopathol 2017;39:910)
- 40 year old woman with skin limited GVHD after pancreatic transplantation (Case Rep Transplant 2017;2017:4823870)
- 58 year old woman with GVHD presenting as fibrosing alopecia in a pattern distribution (Int J Trichology 2018;10:80)
- Chronic GVHD presenting as lichen planus pigmentosus (Bone Marrow Transplant 2018;53:1048)
- Palmoplantar lichen planus-like eruption in a patient with GVHD (J Dermatol 2018;45:e330)
Treatment
- Glucocorticoids in combination with other agents such as antithymocyte globulin, tacrolimus or monoclonal antibodies (Semin Hematol 2006;43:32)
- Topical immunosuppressive therapies for chronic GVHD are linked to less toxicity compared with systemic treatment (An Bras Dermatol 2016;91:336)
- Topical calcineurin inhibitors are of special interest on anatomical sites such as the face or intertriginous areas where potent topical steroids should be used with caution (Br J Dermatol 2011;165:18)
- Psoralens plus ultraviolet A light (PUVA) or narrow band ultraviolet B phototherapy are the treatment choices for sclerotic chronic GVHD lesions (An Bras Dermatol 2016;91:336)
Microscopic (histologic) description
- Vacuolar degeneration of the basal cell layer, dyskeratotic keratinocytes and mild, mononuclear, superficial, perivascular infiltrate (An Bras Dermatol 2016;91:336)
- Epithelial damage occurs, initially at the tips of rete ridges and hair follicles (An Bras Dermatol 2016;91:336)
- These damaged cells are often accompanied by 2 or more lymphocytes, producing the picture known as satellite cell necrosis (lymphocyte associated apoptosis) (J Am Acad Dermatol 1996;35:187)
- Chronic GVHD has 2 stages: lichenoid and sclerodermatous
- Lichenoid GVHD is similar to that of classic lichen planus: hyperkeratosis, hypergranulosis, acanthosis and dyskeratotic keratinocytes with basal cell vacuolization (Clin Dermatol 2005;23:285)
- Sclerodermatous GVHD resembles lichen sclerosus and morphea lesions
- Infiltrate in GVHD developing after solid organ transplantation is usually brisk in comparison to the more sparse inflammation following bone marrow transplantation (J Cutan Pathol 2004;31:179)
- Psoriasiform GVHD is similar to psoriasis; in addition, there is vacuolar interface dermatitis with keratinocyte necrosis within epidermis and adnexal epithelia and lymphocyte satellitosis (Am J Dermatopathol 2018;40:511)

Immunohistochemistry & special stains
- Not applicable
Sample pathology report
- Skin, biopsy:
- Interface dermatitis (see comment)
- Comment: In the context of the clinical history, the morphologic findings are compatible with graft versus host disease (add differential diagnoses if applicable).
Differential diagnosis
- The most important distinguishing feature between GVHD and the diagnoses below is the clinical history of bone marrow or solid organ transplant
- Drug eruption:
- Dense eosinophilic infiltrate (J Am Acad Dermatol 2004;51:543)
- Specificity to completely rule out acute GVHD did not reach 100% until average 16.0 eosinophils/10 HPFs was observed (Am J Dermatopathol 2010;32:31)
- Lupus erythematosus:
- Vacuolar interface reaction, superficial and deep perivascular and periadnexal inflammation
- Dermatomyositis:
- Vacuolar interface reaction, mild superficial perivascular inflammation and abundant dermal mucin deposition
- Psoriasis vulgaris:
- Lacks vacuolar interface inflammation and satellite cell keratinocyte necrosis within the epidermis and adnexal epithelia
- The presence of these features in addition to the classic findings of psoriasis could suggest the possibility of psoriasiform GVHD (Am J Dermatopathol 2018;40:511)
- Lichen planus:
- Denser infiltrate
- Morphea or scleroderma:
- Usually not associated with poikilodermatous surface changes
Board review style question #1
Which of the following histopathological features can help to differentiate graft versus host disease from other interface dermatitis?
- Vacuolar interface reaction, mild perivascular inflammation and abundant dermal mucin deposition
- Vacuolar interface reaction, perivascular and interstitial dense eosinophilic infiltrate
- Vacuolar interface reaction, sparse superficial perivascular inflammation and dyskeratotic keratinocytes involving the adnexal epithelium
- Vacuolar interface reaction, superficial and deep perivascular and periadnexal inflammation
Board review style answer #1
C. Vacuolar interface reaction, sparse superficial perivascular inflammation and dyskeratotic keratinocytes involving the adnexal epithelium. The presence of dyskeratotic keratinocytes involving the adnexal epithelium can help to differentiate between graft versus host disease and other interface dermatitis, such as lupus erythematosus (vacuolar interface reaction, superficial and deep perivascular and periadnexal inflammation), dermatomyositis (vacuolar interface reaction, mild superficial perivascular inflammation and abundant dermal mucin deposition) and drug eruption (vacuolar interface reaction, superficial and deep perivascular and periadnexal inflammation).
