Porokeratosis Plantaris, Palmaris et Diseminata: Description and Characteristics
Porokeratosis constitutes a group of uncommon dermatological conditions characterized by alterations in keratinization [1].
Among them, porokeratosis plantaris, palmaris et diseminata (PPPD) represents an extremely rare form. This condition manifests through the appearance of annular patches annular, reddish-brown in color and scaly in appearance scaly, which initially arise on the palms of the hands and soles of the feet of the patient, subsequently spreading to the extremities and trunk [2].
Who is Affected by Porokeratosis Plantaris, Palmaris et Diseminata?
The clinical onset of PPPD typically occurs during adolescence, although isolated reports of onset at later stages of life exist [3]. Initially, it was documented that PPPD was diagnosed twice as often in men as in women [2]. It is important to note that this condition tends to worsen during the summer months [2].
Underlying Causes of Porokeratosis Plantaris, Palmaris et Diseminata
In the majority of cases, PPPD manifests as a condition predisposition that follows an autosomal autosomal dominant inheritance pattern, manifesting in several members of the same family [4]. However, the appearance of sporadic cases without a known family history is also possible [5].
Distinctive Clinical Features of PPPD
The initial presentation of PPPD is defined by the appearance of reddish-brown annular lesions located primarily on the palms and soles. Over time, these lesions tend to spread to other areas of the body such as the extremities and trunk, taking the form of small, reddish, slightly atrophic macules with well-demarcated borders [1,2].
- In approximately 25% of patients with PPPD, the skin lesions located on the palms and soles may be symptomatic and cause pain [2].
- There are reports associating PPPD with the presence of papules scaly and pointed papules on the palms and soles, termed punctate porokeratosis punctate: it is not yet clear if this presentation constitutes a specific variant of PPPD [6].
- The cutaneous manifestations of PPPD observed on the trunk and extremities may resemble superficial actinic disseminated porokeratosis disseminated superficial actinic (DSAP) [1].
Complications Associated with Porokeratosis Plantaris, Palmaris et Diseminata
PPPD is a chronic y progressive, chronic and progressive condition, which can significantly impact the quality of life of the affected individual. In cases of long duration or substantial chronicity, there is a low, but present, risk that the condition will progress to cutaneous squamous cell carcinoma [7]. cells scars [7].
Diagnosis, Treatment, and Prognosis of Porokeratosis Plantaris, Palmaris et Diseminata (PPPD)
How Porokeratosis Plantaris, Palmaris et Diseminata is Diagnosed
The diagnosis of porokeratosis is generally established based on the clinical evaluation of the skin lesions. However, in uncertain cases, a skin biopsy biopsy may be necessary. Histopathological analysis reveals very characteristic pathological findings of porokeratosis.
Understanding the Differential Diagnosis of PPPD
The establishment of the differential diagnosis mucous membranes. Establishing the differential diagnosis for Porokeratosis Palmaris, Plantaris et Diseminata (PPPD) focuses primarily on distinguishing it from other variants of porokeratosis, notably Actinic Disseminated Porokeratosis of the Extremities (DSAP). DSAP presents similar skin lesions on the extremities but is typically less common on the trunk, and while it spares the hands and feet, it tends to manifest in areas with high sun exposure. In contrast, PPPD can affect any region of the body without this solar predilection.
Treatment Options for Porokeratosis Plantaris, Palmaris et Diseminata
Currently, no definitive cure for PPPD is known, and the response to treatment can be variable and frequently disappointing. Some patients show significant improvement when using oral Topical retinoids such as acitretin or isotretinoin.
Current topical treatments topical frequently include:
- Application of lotion Application of 5-fluorouracil cream.
- Application of 5-fluorouracil cream.
- Use of imiquimod cream.
Calcipotriol ointment.
- Cryotherapy.
- Dermabrasion.
- Cryotherapy Furthermore, destructive physical treatment modalities may be considered: laser.
Cryotherapy. Ultraviolet Radiation Currently, there is no definitive cure for linear porokeratosis, and the response to treatment is often disappointing. However, it is possible to improve the appearance of the lesions through various interventions: development of cancer Dermabrasion. . The cherry angioma is histologically distinguished by being composed of Ablation using carbon dioxide laser.
It is essential to emphasize the importance of sun protection, as exposure to ultraviolet radiation increases the risk of developing skin cancer within the porokeratosis lesion.
Prognosis of Porokeratosis Plantaris, Palmaris et Diseminata PPPD is characterized by being a chronic and progressive disease. Its severity tends to fluctuate, often worsening during the summer months. Although there are positive responses to oral isotretinoin or acitretin, it is common for the condition to relapse.
once pharmacological treatment is discontinued. squamous cells There is a low but latent risk of progression to cutaneous squamous cell carcinoma. For this reason, regular monitoring and dermatological surveillance of skin lesions are essential for the long-term management of PPPD.
