An odontogenic keratocyst is a rare and benign but locally aggressive developmental cyst. It most often affects the posterior mandible and most commonly presents in the third decade of life. [ 1] Odontogenic keratocysts make up around 19% of jaw cysts. [ 2] Despite its more common appearance in the bone region, it can affect soft tissue.
The International Classification of Diseases for Oncology ( ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries . It is currently in its third revision (ICD-O-3).
Cutaneous squamous-cell carcinoma is the second-most common cancer of the skin (after basal-cell carcinoma, but more common than melanoma). It usually occurs in areas exposed to the sun. Sunlight exposure and immunosuppression are risk factors for SCC of the skin, with chronic sun exposure being the strongest environmental risk factor. [26]
Carcinoma is a malignancy that develops from epithelial cells. [ 1] Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal [ 2] or ectodermal germ layer during embryogenesis. [ 3]
Waldenström macroglobulinemia (/ ˈ v æ l d ən s t r ɒ m ˌ m æ k r oʊ ˌ ɡ l ɒ b j ə l ɪ ˈ n iː m i ə / VAL-dən-strom MAK-roh-GLOB-yə-lin-EE-mee-ə, [1] [2] US also / ˈ v ɑː l d ən s t r ɛ m-/ VAHL-dən-strem - [3]) is a type of cancer affecting two types of B cells: lymphoplasmacytoid cells and plasma cells.
Transitional cell carcinoma is a type of cancer that arises from the transitional epithelium, a tissue lining the inner surface of these hollow organs. [ 1] It typically occurs in the urothelium of the urinary system; in that case, it is also called urothelial carcinoma. It is the most common type of bladder cancer and cancer of the ureter ...
Oncology. Surface epithelial-stromal tumors are a class of ovarian neoplasms that may be benign or malignant. Neoplasms in this group are thought to be derived from the ovarian surface epithelium (modified peritoneum) or from ectopic endometrial or fallopian tube (tubal) tissue. Tumors of this type are also called ovarian adenocarcinoma. [1]
Specialty. Oncology. Squamous-cell carcinoma ( SCC) of the lung is a histologic type of non-small-cell lung carcinoma (NSCLC). It is the second most prevalent type of lung cancer after lung adenocarcinoma and it originates in the bronchi. Its tumor cells are characterized by a squamous appearance, similar to the one observed in epidermal cells.
