Introduction: Colon adenocarcinoma is one of the foremost causes of cancer mortality. Oral metastasis of colon adenocarcinoma is, however, rare and indicates an end-stage disease process.   Case Report: We report a case of a 69-year-old female with a gingival mass diagnosed with colon adenocarcinoma and liver metastasis after one year. A swelli...

Schwannoma is a rare benign neural neoplasm derived from Schwann cells of the peripheral nerve sheath. Schwannoma accounts for 25% to 48% of all neoplasm cases in the head and neck region. Oral Schwannoma is an uncommon soft tissue tumor comprising of 1% of all Schwannomas. Tongue is the most common location for oral schwannoma. Occurrence of gingival schwannoma is very rare and less than 10 ca...

Interleukin (IL)-23 is a heterodimeric cytokine comprising IL-12p40 and the recently cloned IL-23-specific p19 subunit. Like IL-12, IL-23 is expressed predominantly by activated dendritic cells and phagocytic cells. Both cytokines induce interferon-γ secretion by T cells, and antagonistically regulate local inflammatory responses in the tumor microenvironment as well as the infiltration of intr...
