Bites, Bullous Insect Bites
Bites, Bullous Insect Bites Definition: Bullous insect bites are delayed hypersensitivity reactions that occur in people who are already sensitized (2). They are characterized by blisters packed with fluid that appear on the skin (1). Etiology: The bites arise from an immune response to toxins being released at the bite site (1). The most common […]
Bites, Arthropod
Bites, Arthropod Definition: Arthropod bites are skin reactions caused by the bite or sting of different arthropods such as arachnids (spiders,ticks), insects (mosquitoes, fleas, and bedbugs), Chilopods (centipedes) and Diplopods (millipedes)(1). Etiology: The skin reaction is brought on by the entry of venom, saliva, or other compounds from arthropods into the skin, which triggers an […]

Familial Lipomatosis/Lipomas
Familial Lipomatosis/Lipomas Condition Name: Familial lipomatosis/lipomas Definition: Familial lipomatosis/lipomas is a hereditary condition characterized by the development of multiple lipomas, which are benign tumours composed of mature fat cells. These soft, mobile, and usually painless nodules can occur anywhere on the body but are most commonly found on the trunk, forearms, and thighs. Etiology: The […]
Hidradenitis Suppurativa
Hiradentitis Suppurativa Definition: Hidradenitis SUppurativa (HS), also known as acne inversa, is a chronic inflammatory skin condition that affects the apocrine-gland-bearing skin. It is characterized by painful, persistent deep-seated nodules, abscessed as skin tunnels that may develop purulent discharge and result in scarring. Etiology: HS development may have genetic, environmental and behavioural influences. There is an […]
