Unknown primary carcinoma presenting as cervical lymph node metastasis accounts for approximately 5% of all head and neck malignancies. The typical presentation involves a middle-aged man with a painless neck mass that has been present for several months.

متن کاملMechanisms of cyst formation in metastatic lymph nodes of head and neck squamous cell carcinoma
Cystic change in metastatic lymph nodes occurs in certain types of tumors and mostly in squamous cell carcinoma of the head and neck. In the majority of cases, psuedocystic change is the mechanism of cyst formation. However, sometimes a true cyst cavity is formed. This occurrence is unexplained and some theories are introduced to explain it. In this paper, related articles and introduced concep...
متن کاملMetastatic hypernephroma to the head and neck.
Hypernephroma is one of the most common visceral adenocarcinomas which metastasize to the head and neck. The metastasis may precede discovery of the primary or follow it. The most common sites of metastatic hypernephroma to the head and neck are the sinonasal tract, skin, cervical lymphatics, and mandible. Three cases of metastatic hypernephroma are presented and one of these is the first docum...
