Basal Cell Carcinoma

چکیده
Basal cell carcinoma (BCC) is the most common type of skin cancer (75% to 80%) and the most common of all cancers (more than one out of every three new cancers). Seventy to eighty percent of BBC occurs in the head and neck region, followed by the trunk (about 25%), and penis, vulva, or perianal skin (about 5%). It is more common in light-skinned individuals (type 1 or type 2 skin) with a family history of BCC and increases in incidence closer to the equator or at higher altitudes. Incidence is relatively low in Asians, Blacks, and Hispanics. The current male-to-female ratio is approximately 2.1:1. BCC incidence increases with age; about 5% to 15% of BCC cases occur in patients aged 20 to 40 years, and the incidence is more than 100-fold in persons aged 55 to 70 years than in those aged 20 years or younger. BCC accounts for about 0.1% to 2% of all patient deaths due to cancer [1].

Basal cell carcinoma (BCC) is the most common malignant tumor of the skin, which originates from the basal cell layer of the skin. It is more common in white race with skin types I and II. Some predisposing factors are sunlight, ionizing radiation, arsenic salts, PUVA and scar. We present a case of BCC, which appeared over an old scar of localized cutaneous leishmaniasis in a 49-year-old woman.
متن کاملThe Usefulness of CD10 in Distinguishing between Cutaneous Basal Cell Carcinoma and Squamous Cell Carcinoma
Background & Objectives: CD10 is a cell surface enzyme with metalloendopeptidase activity, also known as Common Acute Lymphoblastic Leukaemia Antigen, which mainly serves as a marker for acute lymphoblastic leukemia (ALL). To date and to the best of our knowledge, only few comparative immunohistochemical studies have assessed CD10 expression in cutaneous epithelial neoplasms. Our goal was to d...

Background and Objective: Clinical behavior of basal cell carcinoma (BCC) is known to be different according to histological growth pattern and basosquamous cell carcinomas (BSC) are known with their aggressive behavior and metastatic capacity. In this study, we evaluated bcl-2 and cyclin D1 expressions in BCC and BSC cases comparatively, to explore their predictive value on the aggres...

Background: Radiation-induced basal cell carcinoma (BCC) can be multiple, large, and recurring, which complicates its treatment in some cases. According to reports on the role of cyclooxygenase 2 (COX2) inhibitors in the treatment or prevention of non-melanoma skin cancers and considering the fact that COX2 expression has not been evaluated in radiation-in...
