Dermatology Series: Common Skin Disorders

Common skin disorders

From time to time many of us experience certain skin reactions and are virtually clueless on what it is or what caused it. Perhaps this article will shed some light.

Acne

Something 100.00% of us will experience many times is acne. While previous articles have covered acne to a fair depth; it makes sense to mention the most common skin issue in the world again. What causes acne? The combination of the bacteria known as Propionibacterium acnes and sebum. The presence of sebum and bacteria clogs the skin pores allowing for further bacteria growth along with pimple formation and inflammation.

Psoriasis

These tend to be found on the knees and elbows quite often. They’re silver, are larger than 1cm and they are elevated lesions. Often, they lead to bleeding if the scales are torn off.

Hives

Itchy and red bumps on the skin; hives are generally due to some form of allergic reaction from something that was consumed (ex. a medication or a food). 

 

Rosacea

Skin lesions with and without pus inside of them on the face. What generally makes them different from acne is that there isn’t any obstruction present in the skin pores.

Moles

Largely, these are harmless. Future articles will go more in-depth on melanoma but two things are important to always watch. Abnormal moles that begin changing in size/shape/color and those we are born with. 

Eczema

Red, crackled and itchy. Babies get these often and in general they’re more common on the inside of our elbows.

Allergic Reaction

Most people tend to dismiss every abnormal skin finding as being an allergic reaction but that’s not always the case. True allergic reactions lead to lesions occurring at the exact area of contact to whatever the allergen was.

Seborrheic Keratosis

Basically a cyst that is full of a protein known as keratin. They’re generally flat and of course very dark. While these are common among older people, they can also be a sign of an underlying serious issue.

HPV Warts

These don’t always occur on genitals even though they’re caused by HPV which is a sexually transmitted disease. The classic description for these is “cauliflower shaped” and they’re also quite soft. Usually they are caused by HPV-6 & HPV-11 as not all strains of HPV cause warts.
