Chronic cutaneous graft-versus-host disease in children: A report of 14 patients from a tertiary care pediatric dermatology clinic.

Background/objectives: Allogeneic hematopoietic stem cell transplantation (HSCT) is a treatment option for many life-threatening disorders in children. Chronic graft-versus-host disease (cGVHD) is a significant complication of HSCT, and its treatment is challenging. Skin is the most common organ affected in cGVHD, with protean manifestations posing a challenge in diagnosis and management. The objective was to have a better understanding of the spectrum of chronic cutaneous GVHD (cc-GVHD) in children.

Methods: Hospital records of 14 children with cc-GVHD, registered over 9 years, were reviewed.

Results: All the patients had received HSCT from related donors. Median duration between HSCT and onset of cc-GVHD was 7.5 months. Eighty-six percent of the patients had a prior history of aGVHD, and 14% had de novo onset of cc-GVHD. Of 14 patients, 71% had classic cc-GVHD. Overlap syndrome was observed in 29%. Tandem occurrence of multiple morphologies was noticed in 6 (43%) patients. Of classic cc-GVHD, lichen planus-like cc-GVHD was most common (57%) followed by scleroderma-like (29%) and poikiloderma (7%). Rare variants included eczema-like (14%) and psoriasis-like (7%) cc-GVHD. Mucosal involvement was seen in 78.6% of the patients, nail involvement in 50%, and hair abnormalities in 43%. After a median follow-up of 4.8 years, complete remission was observed in 50% and mortality in 14%.

Conclusion: The study signifies the diverse nature of cc-GVHD and indicates the need for multicenter surveys including larger number of patients to have proper insight into and develop treatment guidelines for cc-GVHD in children.
