Cutaneous SCCs present as enlarging scaly or crusted lumps. They usually arise within pre-existing actinic keratosis or intraepidermal carcinoma.
They grow over weeks to months
They may ulcerate
They are often tender or painful
Located on sun-exposed sites, particularly the face, lips, ears, hands, forearms and lower legs
Size varies from a few millimetres to several centimetres in diameter.
Mycosis fungiodes
skin lymphoma (cancer) that affects your body’s T-cells
non-hodkins lymphoma
characterised clinically by progression from patches to plaques to tumours and, on histology, by an epidermotropic infiltrate of small to medium-sized CD4+ T-cells (lymphocytes).
Pityrisis versicolour organism
Malessia furfur
Eythema Toxicum
Most cases of toxic erythema of the newborn begin in the first few days after birth, although onset can be as late as two weeks of age.
Toxic erythema of the newborn is evident as various combinations of erythematous macules (flat red patches) papules (small bumps) and pustules. The eruption typically waxes and wanes over several days and it is unusual for an individual lesion to persist for more than a day.
Toxic erythema of the newborn often begins on the face and spreads to affect the trunk and limbs. Palms and soles are not usually affected.
The infant is otherwise well.
Erysipiles bug
The majority of erysipelas cases are caused by Streptococcus pyogenes, a beta-haemolytic group A streptococci and the rash is caused by an endotoxin rather than the bacteria itself.
Nec fasc bug
group A Streptococcus (group A strep), Klebsiella, Clostridium, E. coli, Staphylococcus aureus

Scaly itchy and red
associated with TCC of bladder
paraneoplastic pemphigus
