Rib desmoplastic fibroblastoma: Video-assisted resection
A 46-year-old man was referred to our department due to chronic chest pain. A computed tomography showed an exophytic image arising from 5th rib that was projected on the middle lobule. The patient underwent an exploratory videothoracoscopic because we couldn't discard lung compromise. A corneal-like lesion emerging from the inner side of the 5th rib was revealed. Complete video-assited resection was done. Histopathology examination revealed a desmoplastic fibroblastoma. To our knowledge this is the first case of desmoplastic fibroblastoma arising from a rib and the second case published in all literature of chest wall involvement
Histamine H4 receptor expression in triple negative breast cancer: an exploratory study
Abstract: Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype.
There are neither universally accepted prognostic markers, nor molecular
targets related to TNBC. The histamine H4 receptor (H4R) has been
characterized in TNBC experimental models, demonstrating its critical role in
tumor development and progression. In this study, H4R expression was
compared in breast cancer subtypes and correlated with clinical features using
The Cancer Genome Atlas data (TCGA, Pan-Cancer Atlas). The H4R status
was further evaluated by immunohistochemistry in 30 TNBC human samples in
relation to clinicopathological parameters. Results indicate that H4R was
downregulated in basal-like/TNBC compared with luminal A and normal breastlike tumors. The higher expression of H4R was associated with improved
progression free and overall survival outcomes in basal-like/TNBC. H4R
immunoreactivity was detected in about 70% of tumors, and its expression was
positively correlated with the levels in the histologically normal peritumoral
tissue. High H4R expression in peritumoral tissue correlated with reduced
number of lymph node involvement and unifocal TNBC while it was associated
with increased patient survival. In conclusion, the H4R might represent a
potential prognostic biomarker in TNBC. Further studies in large cohorts are
needed to better understand the significance of H4R in breast cancer biology
