Abstract:
A 50-year-old man had a maxillectomy and post-operative radiotherapy for squamous carcinoma of the maxilla. The acute skin reaction merged at 2 months into a chronic comedo-type acneiform skin reaction in the irradiated area. Previous literature on this reaction to radiation is reviewed. The reaction is rare and occurs mostly in the head and neck area, more commonly in patients who have received acneigenic drugs, and with a latent period of between 2 weeks and 6 months from completion of radiotherapy. The pathogenesis of acne is discussed and a mechanism of post-irradiation acne is suggested.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
02:49Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
