general, psoriasis is characterized by scaly patches called psoriatic plaques. The plaques
are often quite large, but also occasionally occur as small papules. Sometimes
they have the size and shape of a coin. The disease can also develop on skin folds of your armpit or groin, or
the palms of your hands or soles. However, these symptoms vary from one person and depending on the type of
psoriasis - also called
psoriasis vulgaris, plaque psoriasis accounts for nearly 80% of cases of the disease; which makes it the most
common form of psoriasis. In psoriasis vulgaris, skin lesions are red, irritated, itchy and scaly. When
the plaques are scraped
off, the area
gives an appearance of punctate
bleeding spots, Auspitz's
sign. Symptoms of
plaque psoriasis can develop anywhere in your body including the soft tissue inside your mouth and genital
psoriasis - this skin
condition is uncommon in comparison with psoriasis vulgaris. It occurs mostly following a bacterial infection.
It is characterized by a scattering of small scaly crusted spots over
large areas of your body
on your legs, lower abdomen, lower back, forearm, chest,
or your scalp. Psoriasis guttata does not cause any plaques but small, red, water –drop- like spots which tend
to disappear on their own without leaving any complications.
Erythrodermic psoriasis - erythrodermic psoriasis is a rare but severe form of
psoriasis. It tends to cause inflammation of the skin and may affect your entire body. Most of the times,
erythrodermic psoriasis is due to complication or extension of an existing psoriasis; rarely, development of a
new erythrodermic psoriasis can occur.
The affected area becomes red, sometimes wet, edematous and covered with fine scales.
addition, erythrodermic psoriasis can cause various thermal regulation problems such as chills, cardiovascular disorders, and sometimes fever.
Pustular Psoriasis - this is an uncommon form of psoriasis. It is usually
localized on the palm of your hands, feet and fingertips. Its occurrence consists of multiple small pustules
lesions - small, inflamed, pus-filled lesions. Usually, the patches are milky white or yellowish white, which
can be generalized (generalized pustular psoriasis) or localized (localized pustular psoriasis). Pustules lesions have a tendency to coalescence, they come together so as to
form one whole.
Inverse psoriasis - also called Inverted psoriasis, inverse psoriasis
affects mostly the skin folds such as armpits, groin, under the breasts, under stomach (mostly in overweight
people), the genital areas and rarely the belly button. It is characterized by bright red inflamed patches,
which can be smooth and little scaly.
Nail psoriasis - nail psoriasis is another frequent form of psoriasis;
it occurs in more than 50% of cases of psoriasis. Usually, it is characterized by an abnormal growth and
discoloration of the fingernails and toenails. As the disease worsens, you will observe lines going across the
nails, which make them (the infected nails) become loose and crumble. In addition, the skin under the infected
nails becomes thick.
Psoriatic arthritis – this form of psoriasis affects your joint and
connective tissue. It is characterized by a chronic inflammatory arthritis and skin lesions. The inflammation
affects mostly the neck, back, fingers and the spine. Although rare, complications can lead to inflammatory eye
disease, joint damage and permanent deformity. Psoriatic arthritis represents about 10 to 15% of all psoriasis
