Stromal elements present within the tumor microenvironment may suppress host immunity and promote the growth of malignant lymphocytes in B cell-derived non-Hodgkin lymphoma (NHL). In contrast, little is known about the microenvironment's role in T cell-derived NHL. B7-H1 (PD-L1, CD274), a member of the B7 family of costimulatory/co-inhibitory ligands(More)
T1 melanomas, despite their favorable prognosis, account for 25% of melanoma deaths. The American Joint Committee on Cancer (AJCC) 7th edition melanoma staging, implemented in 2010, replaced the level of invasion with the mitotic rate for T1 substaging, on the basis of prognostic modeling, not prediction of occult lymph node metastasis. Previously, sentinel(More)
A variety of nonmalignant cells present in the tumor microenvironment promotes tumorigenesis by stimulating tumor cell growth and metastasis or suppressing host immunity. The role of such stromal cells in T-cell lymphoproliferative disorders is incompletely understood. Monocyte-derived cells (MDCs), including professional antigen-presenting cells such as(More)
BACKGROUND Communication failures between clinicians and dermatopathologists are prevalent. Our primary objective was to characterize the concerns and challenges of dermatopathologists posed by incomplete or inaccurate clinical information in the skin biopsy requisition form. METHODS An explanatory sequential, mixed-methods study design comprised of a(More)
Patient-centered emergency diagnostic imaging relies on efficient communication and multispecialty care coordination to ensure optimal imaging utilization. The construct of the emergency diagnostic imaging care coordination cycle with three main phases (pretest, test, and posttest) provides a useful framework to evaluate care coordination in(More)
PURPOSE To summarize characteristics and validity evidence of tools that assess teamwork in undergraduate medical education (UME), and provide recommendations for addressing the interprofessional collaboration competencies of the Association of American Medical Colleges (AAMC). METHOD The authors conducted a systematic review, searching MEDLINE, MEDLINE(More)
Current pathologic criteria cannot reliably distinguish cutaneous anaplastic large cell lymphoma from other CD30-positive T-cell lymphoproliferative disorders (lymphomatoid papulosis, systemic anaplastic large cell lymphoma with skin involvement, and transformed mycosis fungoides). We previously reported IRF4 (interferon regulatory factor-4) translocations(More)
Cutaneous gamma-delta T-cell lymphoma (γδTCL) is a rare malignancy that typically displays an aggressive clinical course. We present an unusual case of a 57-year-old woman with a 3-year history of lower extremity nodules. Histopathologic, immunophenotypic and molecular genetic studies revealed a clonal, predominantly pannicular gamma-delta T-cell(More)
BACKGROUND B-cell chronic lymphocytic leukemia (B-CLL) is a low-grade lymphoproliferative disorder with characteristic histomorphologic features and an identifiable immunophenotype. The skin can be involved in the context of known disease, but cutaneous signs are rarely the presenting findings. OBJECTIVE Evaluation of unusual clinical cutaneous(More)
The advent of personalized medicine has ushered in a new era for cancer therapy with a significant impact on the management of advanced melanoma. Molecular targeted therapies have shown promise in the management of various malignancies, including melanoma, with lower toxicity profiles and better overall survival as compared with conventional therapy.
