ABSTRACT

BACKGROUND/OBJECTIVES: Complications of hematopoietic stem cell transplant (HSCT) include acute graft-versus-host disease (aGVHD). Severe cutaneous aGVHD can present with generalized erythroderma, desquamation, and bullae which can mimic toxic epidermal necrolysis (TEN). TEN occurs in response to a culprit medication. Transplant patients are often on many medications, making it difficult to distinguish between the two conditions. Given that TEN-like aGVHD is rare, we describe a case series of pediatric patients and review the literature. METHODS: This is a multi-institutional case series of children who developed TEN-like aGVHD following bone marrow transplantation. Demographic, clinical, and treatment information was collected. RESULTS: Ten patients were identified. Median age at transplantation was 8.5 years (range 0.12-17 years). Median time from transplant to first skin symptoms was 35 days (range 6-110 days) and to first TEN-like symptoms was 40 days (range 16-116 days). 7/10 had other organ GVHD involvement. All patients were on concurrent medications at time of first skin symptoms including immunosuppression for GVHD prophylaxis, infection prophylaxis or treatment, and pain medication. Treatments for TEN-like aGVHD included immunosuppression. CONCLUSIONS: We observe that patients with > or equal to 50% BSA involvement of their skin with TEN-like aGVHD, extracutaneous GVHD, and lack of reepithelization tend to have poor outcomes. Given the rarity of this condition, multidisciplinary care of these patients is important for accurate and timely diagnosis and treatment.

ABSTRACT

Primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder (PCSM-TCLPD) is a rare benign lymphoproliferative disorder, recently redefined by the 2016 World Health Organization classification of lymphoid neoplasms. In adults, PCSM-TCLPD responds well to monotherapy with surgical excision or local radiation, with or without topical/injected corticosteroids; in contrast, PCSM-TCLPD has only rarely been reported in children, in whom treatments favored in adults may be non-optimal. We present a 14-year-old male with PCSM-TCLPD on the forehead, who achieved complete remission following biopsy, topical corticosteroids, and surgical excision. We also review all literature-reported cases of pediatric PCSM-TCLPD, emphasizing the disorder's benign nature and treatment responsiveness in children.

ABSTRACT

We describe a 14-year-old boy with Wilson disease (WD) who first developed pseudo-pseudoxanthoma elasticum (PPXE) after 4.5 years of treatment with D-penicillamine. Although previously reported cases have occurred in adults following at least a decade of high-dose D-penicillamine use, this case demonstrates that D-penicillamine-induced PPXE can present in children with shorter treatment courses. Upon this diagnosis, the patient was switched from D-penicillamine to trientine, with adequate cupriuresis and stabilization of the skin lesion. Prompt diagnosis and management of PPXE in children can limit systemic progression and prevent long-term complications.
