Skin Diseases That Start With P

Skin diseases are a common condition that can affect anyone, regardless of age, gender, or race. These diseases can have a wide range of causes, including genetic factors, environmental toxins, and infectious agents such as bacteria, viruses, and fungi. Some of the most common skin diseases include acne, eczema, psoriasis, and rosacea. While many skin diseases are benign and self-limited, others can be chronic, debilitating, and even life-threatening if left untreated.

To create an all-encompassing list of skin diseases, I adopted an alphabet-based approach that involved researching and compiling skin conditions that started with each letter. This strategy ensured that even the rarest skin conditions were incorporated into the list.

So, let’s begin exploring this list of skin diseases starting with P!

105 Skin Diseases That Start With P

And here’s the list of skin diseases that begin with P letter.

Pseudoporphyria

Pseudoporphyria is a rare cutaneous disorder that is characterized by blistering and scarring. It is often mistaken for porphyria due to similar symptoms, but the underlying causes are different. Pseudoporphyria is commonly associated with chronic kidney failure or excessive use of certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or antibiotics.

Phaeohyphomycosis

Phaeohyphomycosis is a type of fungal infection that affects the skin and underlying tissues. It is caused by various types of fungi, including dematiaceous fungi. The symptoms typically include skin lesions, abscesses, or nodules that may be black, brown, or gray in color. Treatment usually involves a combination of antifungal medications and surgical excision of the affected tissues.

Piloleiomyoma

Piloleiomyoma is a benign tumor that arises from the smooth muscle cells of the arrector pili muscles in the skin. It typically presents as a small, firm, and solitary nodule that is usually painless but can be tender to touch. Treatment usually involves surgical excision of the tumor, but it may recur after removal.

Pilonidal sinus

Pilonidal sinus is a condition that affects the skin at the cleft of the buttocks. It is characterized by the formation of a small, painful, and inflamed cyst or sinus tract. The condition is often caused by an ingrown hair in the area, which can become infected and lead to abscess formation. Treatment typically involves incision and drainage of the abscess or surgical excision of the affected tissue.

Platonychia

Platonychia is a condition that affects the nails, causing them to flatten and lose their natural convexity. It is often associated with chronic medical conditions, such as lung cancer, bronchiectasis, or tuberculosis. The condition can also be induced by trauma or pressure on the nail bed. Treatment usually involves addressing the underlying cause and allowing time for the nail to grow out normally.

Plica neuropathica

Plica neuropathica is a rare condition that affects the scalp, causing the hair to form into tightly twisted and matted tufts. The condition is often associated with psychiatric disorders, such as schizophrenia or obsessive-compulsive disorder, but it can also be induced by chronic traction or pressure on the hair. Treatment typically involves behavioral therapy to address the underlying psychiatric condition.

Psoriatic nails

Psoriatic nails are a manifestation of psoriasis that affects the nail bed and matrix. The nails may develop pits, ridges, or grooves, and may become discolored, thickened, or crumbly. The condition can also cause onycholysis, or separation of the nail from the nail bed. Treatment usually involves systemic or topical medications that target the underlying psoriatic disease.

Porocarcinoma

Porocarcinoma is a rare and aggressive skin cancer that arises from the sweat ducts in the skin. It typically presents as a solitary, dome-shaped nodule that may be painful or bleeding. The condition is often misdiagnosed as other skin tumors, such as basal cell carcinoma or squamous cell carcinoma. Treatment typically involves surgical excision of the tumor, but the prognosis can be poor if the cancer has metastasized.

Proteus-like syndrome

Proteus-like syndrome is a rare genetic disorder that affects multiple systems in the body, including the skin and bones. The condition is characterized by overgrowth of tissue, such as skin and bone, and may present with asymmetric limb size, macrodactyly, or macrocephaly. Treatment usually involves symptomatic and supportive care, as there is no cure for the condition.

Perioral dermatitis

Perioral dermatitis is a common skin condition that affects the face, particularly around the mouth, nose, and eyes. It is characterized by the appearance of small, red, and itchy papules that may be grouped in a rash. The condition is often triggered by topical steroids or cosmetics and may be worsened by stress or sunlight exposure. Treatment typically involves discontinuing the causative agent and using topical or oral medications to reduce inflammation.

Papular xanthoma

Papular xanthoma is a benign skin condition that is characterized by the appearance of yellowish-brown papules on the skin. The condition is often associated with hyperlipidemia or other metabolic disorders, but may also occur in healthy individuals. The papules typically occur on the elbows, knees, or buttocks. Treatment usually involves managing the underlying metabolic disorder and may include surgical removal of the papules.

Psoriatic erythroderma

Psoriatic erythroderma is a severe manifestation of psoriasis that affects the entire skin surface. It is characterized by widespread erythema, scaling, and inflammation of the skin, and may be associated with fever, chills, and malaise. The condition can cause significant morbidity and mortality and requires urgent medical attention. Treatment typically involves hospitalization, systemic medications, and supportive care.

Photoirritant

Photoirritation is a cutaneous phototoxic reaction that occurs when the skin is exposed to certain chemicals or medications in the presence of sunlight. The condition is characterized by erythema, edema, and itching of the affected skin. Treatment typically involves discontinuing the causative agent and using topical or oral medications to reduce inflammation.

Photosensitivity

Photosensitivity is a condition that results in an abnormal skin reaction to sunlight or artificial light. The condition is often associated with systemic diseases, such as lupus or porphyria, or with certain medications, such as diuretics or antibiotics. The symptoms may include erythema, blistering, or rash formation. Treatment usually involves avoiding exposure to the triggering light source and using sunscreen or protective clothing.

Pressure ulcer

Pressure ulcers are a type of skin injury that occurs when there is prolonged pressure on the skin, often in bony prominences. The condition is characterized by the formation of a shallow or deep wound that may become infected or necrotic. Treatment typically involves removing the pressure source, keeping the wound clean and moist, and using topical or oral medications to promote healing.

Pressure alopecia

Pressure alopecia is a type of hair loss that is caused by prolonged pressure on the scalp, often due to tight hats, helmets, or headbands. The condition is characterized by hair breakage, thinning, or bald patches in the areas of pressure. Treatment typically involves removing the pressure source and allowing time for hair regrowth.

Plantar fibromatosis

Plantar fibromatosis is a benign tumor of the plantar fascia, the thick band of tissue that runs along the sole of the foot. The condition is characterized by the formation of a firm nodule or band of tissue that may be painful or limit mobility. Treatment may involve conservative methods, such as stretching or orthotics, or surgical excision of the affected tissue.

Photoaging

Photoaging is a type of skin aging that is caused by chronic exposure to sunlight or artificial light. The condition is characterized by fine lines, wrinkles, pigmentation changes, and loss of elasticity in the skin. Treatment may involve using topical or oral medications that stimulate collagen production, or using cosmetic procedures, such as laser resurfacing or chemical peels, to improve the appearance of the skin.

Wrapping Up

And that’s our list of P skin diseases.

I approached the creation of a complete list of skin diseases with careful consideration and persistence. Researching each alphabet individually and finding corresponding skin conditions resulted in a well-rounded list of skin diseases.

In summary, skin diseases represent a broad category of medical conditions that cover everything from rashes and acne to serious autoimmune disorders. Treatment options will often depend on the cause and severity of the condition. While some skin diseases resolve on their own or respond well to over-the-counter creams, others may require prescription-strength medication, phototherapy, or surgery. To minimize the chances of developing skin diseases, individuals should adopt a healthy lifestyle that includes regular exercise, a balanced diet, and diligent skincare. Additionally, recognizing and avoiding potential irritants such as certain fabrics, harsh soaps, and extreme temperatures can also minimize the risks.

Hope this post on skin diseases beginning with P alphabet has been useful to you!
