Giant cell tumor of soft tissue of the breast: case report with H3F3A mutation analysis and review of the literature

We report a unique case of breast GCT-ST coincident with ductal carcinoma in situ (DCIS), diagnosed with histological, immunohistochemical, and H3F3A (Histone H3.3) mutation analyses. A 59-year-old woman preoperatively diagnosed with DCIS underwent total mastectomy for a cystic mass. Histology revealed a tumor composed of mononuclear cells interspersed with numerous osteoclast-like giant cells, resembling giant cell tumor of bone (GCT-B), with apocrine DCIS in proximity to the tumor. The mononuclear and giant cells were immunoreactive for CD68 and negative for cytokeratins. Granulomatous diseases, carcinomas with giant cells, and giant cell-type sarcomas were excluded by histological and immunophenotypic features. Lack of H3F3A mutation eliminated the possibility of GCT-B metastasis to the breast. These findings were consistent with GCT-ST of the breast. To our knowledge, this is the ninth reported case of breast GCT-ST, but the first case that accompanied DCIS or involved H3F3A mutation status investigation. For correct diagnosis of this rare tumor, it is important for pathologists to raise the possibility of GCT-ST when encountering giant cell-rich breast lesions and to exclude other differential diagnoses by combining the results of histological, immunohistochemical, and genetic analyses.

ConclusionIn a large series of advanced ovarian cancer, patients receiving late IDS (≥ 5 NAC cycles) seem to show a poorer prognosis than patients operated on earlier. The survival appears to be mainly determined by optimal resection and response to chemotherapy.

ConclusionsLuminal A tumor was the most prevalent subtype, while HER2-positive was the least prevalent. Luminal A tumors were mostly associated with lobular carcinomas. HER2-positive and triple negative tumors showed higher histological grade and larger tumor size at the time of diagnosis. These tumors were commonly found in women below the age of 50 years. Carcinoma-in-situ was less prevalent in HER2-positive tumors. Furthermore, a strong association was observed between axillary lymph node status and molecular subtypes.

ThuluvathAbstractThe use of immunotherapy in transplant recipients is considered a contraindication because of very high risks for graft loss. The graft loss is to be expected since cytotoxic T-lymphocyte associated protein-4 (CTLA-4) and PD-1 pathways are implicated in graft tolerance. In this case report, we describe a woman with recurrent, disseminated hepatocellular carcinoma who was successfully treated with nivolumab, an immune checkpoint inhibitor.

In this study, the immunohistochemistry results demonstrated that DEPDC1 was high-expressed in breast cancer tissues compared with the paired adjacent normal breast tissues, and its tendency at protein level was consistent with mRNA level from TCGA data. Moreover, DEPDC1 mRNA level revealed the strongest association with poor prognosis and development in breast cancer. In vitro assays showed that DEPDC1 overexpression resulted in significant promotion of proliferation by regulating cell cycle in MCF-7 cells, whilst an opposite effect was found in the MDA-MB-231 cells with DEPDC1 deletion. Notably, further investigation ind...

This study sought to weigh the risk of RAS with the benefits of BCS+RT for DCIS. METHODS: A second-order Monte Carlo micro-simulation model of women ages 35 and older with DCIS was constructed. The decision analysis compared harm-benefit ratios of sarcoma-related deaths per breast cancer deaths averted within 20 years of treatment with BCS+RT versus BCS alone. Stratified analyses were performed by age group to account for differential life expectancy. To generate parameter estimates for model inputs, Bayesian network meta-analysis was used to synthesize rates of DCIS and invasive recurrence from clinical trials of BCS+RT a...
