Cutaneous manifestations of human T-cell lymphotrophic virus type-1-associated adult T-cell leukemia/lymphoma: A single-center, retrospective study - 13/01/15
Abstract |
Background |
Limited data exist regarding cutaneous involvement of adult T-cell leukemia/lymphoma (ATLL), particularly in the United States.
Objective |
We sought to characterize clinical and histopathologic features of ATLL in patients with skin involvement.
Methods |
We retrospectively identified patients with ATLL from a single institution given a diagnosis during a 15-year period (1998-2013). Patients were categorized by the Shimoyama classification and stratified into skin-first, skin-second, and skin-uninvolved courses.
Results |
The study population included 17 skin-first, 8 skin-second, and 29 skin-uninvolved cases. Skin-first patients (6 acute, 1 lymphoma, 4 chronic, 6 smoldering) were overwhelmingly of Caribbean origin (94%). They had longer median symptom duration (11.9 vs 1.9 months, P < .001) and overall survival (26.7 vs 10.0 months, P < .001) compared with skin-second/skin-uninvolved patients. Cutaneous lesion morphology at diagnosis included nodulotumoral (35%), multipapular (24%), plaques (24%), patches (12%), and erythroderma (6%). After initial skin biopsy, 14 of 17 received a non-ATLL diagnosis, most commonly mycosis fungoides (47%). Notable histopathologic findings from 43 biopsy specimens included greater than or equal to 20:1 CD4:CD8 ratio (79%), angiocentrism (78%), CD25+ (71%), large cell morphology (70%), CD30+ (68%), epidermal infiltration of atypical lymphocytes (67%) forming large Pautrier-like microabscesses (55%), and folliculotropism (65%).
Limitations |
This was a retrospective, single-center, tertiary referral center study with small sample size.
Conclusion |
Skin-first patients with ATLL in the United States are diagnostically challenging. Familiarity with clinicopathologic features may aid in diagnosis.
