Dedifferentiation, defined as the loss of cellular features of terminal differentiation resulting in a more primitive, unspecialized phenotype, is a rare phenomenon in melanoma and more commonly observed in the metastatic setting than in primary melanomas. The diagnosis of dedifferentiated melanoma poses a significant challenge, and the tumors need...

Epithelioid hepatic angiomyolipoma (HAML) is a rare benign tumor predominantly found in women. Its occurrence during pregnancy is extremely rare. Accurate diagnosis of HAML is challenging due to its radiological resemblance to other hepatic neoplasms. We present a case of epithelioid HAML in a pregnant patient, highlighting the diagnostic and manag...

Only a fraction of patients with cutaneous lupus erythematosus (CLE) will eventually progress toward systemic disease (SLE). To find inflammatory biomarkers which could predict the progression of cutaneous lupus erythematosus (CLE) into systemic lupus erythematosus (SLE) using immunohistochemical (IHC) assays. Immunohistochemical markers for cytoto...

Breast cancer is one of the most common cancers in the world. It is a multifaceted malignancy with different histopathological and biological features. Molecular biomarkers play an essential role in accurate diagnosis, classification, prognosis, prediction of treatment response, and cancer surveillance. This study investigated the clinico-pathologi...

AT-rich interactive domain 1A (ARID1A) is frequently mutated in gastric cancer (GC), especially Epstein-Barr virus (EBV)-associated and microsatellite instability high GC. The loss of ARID1A expression has been reported as a poor prognostic marker in GC. However, the relationships between ARID1A alteration and EBV-associated and microsatellite inst...

Bone metastases of hepatocellular carcinoma (HCC) are rare and disease-revealing bone metastasis are exceptional. Here, we report the case of a 69-year-old man with a cervical vertebral metastasis of hepatocellular carcinoma. Morphological aspect of a metastatic tumor with eosinophilic and polygonal cells raises the question of the differential dia...

Accumulated evidence has shown that endocan, which was originally called endothelial cell-specific molecule-1, is an attractive prognostic factor in a variety of cancers. However, the relevance of endocan expression in human malignancies remains to be clarified. In the present study, the expression of endocan in cervical squamous neoplasia of the u...

Inflammatory myofibroblastic tumor (IMT) is a rare tumor composed of mesenchymal myofibroblastic spindle cells enveloped by an inflammatory infiltrate. Historically, this tumor sparked debate regarding whether it was a true malignancy with metastatic potential or merely a locally destructive physiologic inflammatory response. Few reports of IMT exi...

The significance of the non-classical G-protein-coupled estrogen receptor (GPER) as positive or negative prognostic factor for ovarian cancer patients remains still controversial. Recent results indicate that an imbalance of both co-factors and co-repressors of nuclear receptors regulates ovarian carcinogenesis by altering the transcriptional activ...
