Objectives:
The purpose of this study was to review the clinico-pathologic findings and outcome of patients with metastasis to the parotid lymph nodes and gland.
Methods:
Retrospective study. Thirty-four out of 520 patients with a parotid mass treated at our institution met the criteria for this study. Age, gender, clinical findings, histopathology, treatment. and outcome were analyzed.
Results:
Twenty-three patients had metastases to parotid lymph nodes from a squamous cell carcinoma of the skin, seven from a cutaneous malignant melanoma after a mean interval of 15 months, two from a ductal breast carcinoma, one with a metastatic disease from a rhabdomyosarcoma of the lower limb, and one from a Merkel cell carcinoma. The 5-year cause-specific and absolute survival for squamous cell carcinoma was 64% and 48% respectively and 71% and 57% for malignant melanomas.
Conclusions:
Metastatic disease to the parotid gland is mostly caused by squamous cell carcinoma. Despite combined treatment modalities long-term survival remains poor.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
02:07Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...
