Mycosis fungoides (MF) is an indolent, uncommon, non-Hodgkin T-cell lymphoma of the skin. It classically presents with patches, plaques, and tumors and may rarely show spread to internal organs or bone marrow. Up to 7.5% of MF patients may be diagnosed with a second malignancy. Intravascular large B-cell lymphoma (IVLBCL) is an exceedingly rare non-Hodgkin B-cell lymphoma characterized by predominant growth of large neoplastic cells in the lumina of blood vessels. This case presents with an unusual confluence of two rare diagnoses, MF and IVLBCL, made more remarkable by the presence of both diagnoses on a single skin biopsy sample. 相似文献

Kava is a traditional beverage of various Pacific Basin countries. Kava has been introduced into the mainstream U.S. market principally as an anti-anxiety preparation. The effects of the long-term consumption of kava have not been documented adequately. Preliminary studies suggest possible serious organ system effects. The potential carcinogenicity of kava and its principal constituents are unknown. As such, kava extract was nominated for the chronic tumorigenicity bioassay conducted by the National Toxicology Program (NTP). At present toxicological evaluation of kava extract is being conducted by the NTP. The present review focuses on the recent findings on kava toxicity and the mechanisms by which kava induces hepatotoxicity. 相似文献

Ethnic and racial diversity in the United States has led to increasing interest in research on biculturalism, yet the meaning and underlying processes of biculturalism in the context of development in young adults are not well understood. Fifteen interviews were conducted with second-generation Chinese American women to explore how being bicultural fit into their lives. Data analysis yielded a developmental map that reflected their experiences throughout life as minority women. Findings suggest that biculturalism is more than being functionally competent in two cultures, it is both a behavioral and psychological orientation in life. From the findings of this study, we have increased our knowledge of Asian American women's development and provided a foundation for nursing research with minority women. 相似文献
