Summary
Kuttner tumor, also known as chronic sclerosing sialadenitis, is an under-recognized benign salivary gland condition. Surgical excision is often required for accurate diagnosis, highlighting its frequent misdiagnosis as neoplasia.
Area of Science:
- Surgical Pathology
- Otorhinolaryngology
- Head and Neck Surgery
Background:
- Kuttner tumor, or chronic sclerosing sialadenitis, presents as a firm salivary gland swelling.
- It is often misdiagnosed as neoplasia due to its clinical presentation.
- This inflammatory condition is under-recognized in surgical pathology and cytology literature.
Purpose of the Study:
- To describe the clinical experience with Kuttner tumor.
- To evaluate diagnostic and surgical treatment outcomes for chronic sclerosing sialadenitis.
- To underscore the diagnostic challenges and prevalence of this entity.
Main Methods:
- Retrospective analysis of 7 patients diagnosed with chronic sclerosing sialadenitis between 1999 and 2010.
- Evaluation included patient demographics, history, diagnostic procedures, surgical treatment extent, and complications.
- Surgical interventions involved submandibular gland extirpation and parotidectomy.
Main Results:
- The study included 4 males and 3 females, with a mean age of 55 years.
- The submandibular gland was affected in 85.7% of cases; parotid glands in 14.3%.
- All patients underwent surgical treatment, with submandibular gland extirpation in 6 cases and parotidectomy in 1.
Conclusions:
- Chronic sclerosing sialadenitis may be more common than currently recognized.
- Accurate diagnosis is frequently made only after surgical excision of the affected gland.
- The condition's presentation often leads to misdiagnosis as malignancy.

01:05Cancer-Critical Genes II: Tumor Suppressor Genes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
