Primary plasma cell leukaemia with unusual presentations: a case series.

We present here three cases of plasma cell dyscrasias; first case presenting as primary plasma cell leukemia showing unusual morphology and aberrant expression of myeloid markers; the second case presenting as plasma cell leukaemia with atypical plasma cells in peripheral blood and the third case presenting as myelomatous pleural effusion after treatment for myeloma.

SOSTDC1 down-regulation of expression involves CpG methylation and is a potential prognostic marker in gastric cancer.

Sclerostin domain containing 1 (SOSTDC1) is reportedly down-regulated in various cancers. Our purpose was to study whether epigenetic mechanisms were involved in the down-regulation of expression in gastric cancer. Expression analysis of SOSTDC1 in gastric cancer cell lines indicated mRNA down-regulation.
