Abstract
Porokeratosis is a heterogeneous group of keratinising disorders characterised by the presence of particular microscopic structural changes, namely the presence of the cornoid lamella. This structure develops as a consequence of a defective isoprenoid pathway, critical for cholesterol synthesis. Commonly recognised variants include disseminated superficial actinic porokeratosis, disseminated superficial porokeratosis, porokeratosis of Mibelli, palmoplantar porokeratosis (including porokeratosis palmaris et plantaris disseminata and punctate porokeratosis), linear porokeratosis, verrucous porokeratosis (also known as genitogluteal porokeratosis), follicular porokeratosis and porokeratoma. Apart from the clinical presentation and epidemiology of each variant listed, this review aims at providing up-to-date information on the precise genetic background, introduces imaging methods facilitating the diagnosis (conventional and ultraviolet-induced fluorescence dermatoscopy, reflectance confocal microscopy and pathology), discusses their oncogenic potential and reviews the literature data on the efficacy of the treatment used, including the drugs directly targeting the isoprenoid-mevalonate pathway.

Abstract
Eruptive pruritic papular porokeratosis (EPPP) is a subtype of porokeratosis (PK). EPPP is characterized by intense itching and challenging to treat in some cases. Herein, for the first time, a case of successful relief of EPPP treated with abrocitinib was reported. A 75-year-old male with a 60-year history of PK suddenly experienced severe itching in the past 6 months. The patient's use of antihistamines, prednisone, vitamin A derivatives, vitamin D derivatives, and tripterygium wilfordii showed poor efficacy. Abrocitinib is a highly selective JAK1 inhibitor, and JAK1 appears to play a crucial role in pruritic diseases. Abrocitinib can quickly relieve itching within 24 hours. Before abrocitinib treatment, the visual analog scale (VAS) score was 10, the 12-item pruritus severity scale (12-PSS) score was 19, and the dermatology life quality index (DLQI) score was 18. Abrocitinib (100 mg) was taken orally once a day. After 1 month of oral administration of abrocitinib, the skin lesions gradually subsided, pruritus was relieved, and no adverse side effects occurred. The VAS, 12-PSS, and DLQI scores of the patient decreased to 2, 3, and 4, respectively. This report suggests a potential therapeutic benefit of abrocitinib in managing EPPP. However further investigations with larger sample sizes and controlled studies are necessary to validate its efficacy as a clinical therapy.

Abstract
Eruptive pruritic papular porokeratosis (EPPP) is a rare subtype of porokeratosis that presents as an acute exacerbation of an annular papule with a distinct peripheral hyperkeratotic ridge border and severe pruritus. EPPP is mainly reported in elderly East Asian men. Its etiology and pathogenesis are unknown. We hereby present a case report of EPPP in a 68-year-old Chinese male with persistent circumscribed papules on the extremities, accompanied by severe pruritus for one year. After the patient was given conventional medication, a new rash appeared on the patient's extremities and he felt intense itching in the area of the rash. The patient was switched to oral tofacitinib treatment. The patient felt that the pruritus had largely disappeared after one month of oral dosing, leaving only brown pigmentation on the erythema of the extremities. The patient has been off the drug for 2 months. There was no pruritus or new rash during the follow-up period.

Abstract
Porokeratosis comprises a group of heterogeneous and uncommon acquired or congenital skin diseases of unknown origin characterized by a keratinization disorder resulting from abnormal clonal expansion of keratinocytes. Numerous genetic mutations are thought to be involved. These conditions are characterized histologically by the presence of a cornoid lamella. Clinical manifestations are variable, with localized, disseminated, and even eruptive forms. Porokeratosis has been associated with immunosuppression, ultraviolet radiation, and systemic, infectious, and neoplastic diseases. Many authors consider it to be a premalignant condition because of the potential for malignant transformation to squamous cell or basal cell carcinoma. Therefore, long-term follow-up is a key component of treatment, which is usually complex and often unsatisfactory. We review the latest advances in our understanding of the pathogenesis, diagnosis, and treatment and propose a treatment algorithm.

Abstract
Porokeratosis is a family of several disorders characterized histologically by the presence of cornoid lamellae. The presence of cornoid lamellae represents an abnormal form of keratinization, which unifies all types of porokeratosis. A significant variation in lesional morphology can result from peculiarities involving the cornoid lamellae and changes related to epidermal hyperplasia and dermal inflammation. This diversity has led to the recognition of several unusual clinicopathological variants of porokeratosis in recent years. Cornoid lamellation, however, is not pathognomonic of porokeratosis and can be seen in some inflammatory and inherited cutaneous disorders and also as an incidental finding. Some of these conditions can be confused with an atypical presentation of porokeratosis and vice versa. An awareness of the broad morphological spectrum of porokeratosis is crucial to avoid missing the diagnosis when appearances are far from typical. This issue is critical in patient management given the potential premalignant nature of porokeratosis.

Abstract
Eruptive disseminated porokeratosis (EDP) is a disease that presents clinically with sudden onset of erythematous papules and plaques, with a ridge-like border histologically represented by a cornoid lamella. We report a case of EDP occurring in a 39-year-old woman 3 days after completion of a 2-week course of oral corticosteroid therapy for an acute asthma exacerbation. The patient was treated with emollients and sun protection. Unlike the more chronic disseminated superficial (actinic) porokeratosis, EDP secondary to immunosuppression from corticosteroid therapy has very rarely been reported in the dermatological literature.

Abstract
Disseminated superficial porokeratosis (DSP) is a keratinization disorder characterized by multiple small lesions with a slightly elevated, sharply defined ridge over the whole body. Unusual DSP cases with acute exacerbation of their lesions accompanied by severe pruritus have been reported and designated as "eruptive pruritic papular porokeratosis" or "inflammatory DSP". Histologically, the pruritic lesions in the majority of these unusual DSP cases had a dense infiltration of eosinophils and lymphocytes in the vicinity of blood vessels in the upper dermis. In this report, we describe an additional case of DSP with a similar clinical course and histopathological findings. A review of the literature showed that the pruritic condition in these unusual DSP cases can be transient and is not necessarily related to spontaneous regression. We propose the term "Inflammatory stage of DSP" for describing this unusual variant of DSP.

Abstract
Disseminated superficial porokeratosis (DSP) is a specific disorder of keratinization. Genetic studies show that DSP is an autosomal dominant trait. Clinically, the lesions show a sharply demarcated and hyperkeratotic plaque with central atrophy. The lesions appear mainly in the extremities and generally develop with bilateral symmetry. Unusual cases of DSP accompanied by severe pruritus have been reported as "eruptive pruritic papular porokeratosis" or "inflammatory DSP." Histopathologically, inflammatory DSP is characterized by the presence of cornoid lamella with a dense infiltration of eosinophils and lymphocytes in the perivascular area of the upper dermis. Here we report a case of inflammatory DSP in a 84-year-old man with colon cancer who presented with multiple hyperpigmented atrophic macules.

Abstract
Porokeratosis is a chronic skin disorder characterized clinically by the presence of crater-like patches with an elevated thick keratotic border and central atrophy. Histology reveals cornoid lamellae. While porokeratosis is practically asymptomatic, a pruritic variant has been reported. We recently encountered an 82-year-old man with pruritic porokeratosis. He presented with erythematous papules and intensively itchy patches on his lower limbs that had been present for 6 months. Histopathological examination revealed the characteristic cornoid lamellae. We describe this case in detail and provide a review of the published work.

Abstract
We report a 50-year-old Korean patient who developed a disseminated superficial actinic porokeratosis (DSAP) with two types of lesions. One was a typical DSAP lesion clinically and histopathologically. The other was clinically similar to prurigo nodularis, but histologic examination showed the findings of porokeratosis such as cornoid lamellae and loss of the granular layer in addition to those of chronic lichenified dermatitis, so it could be described as prurigo nodularis-like porokeratosis. The nodular lesions seemed to develop on preexisting typical lesions of DSAP mainly during the summer by the aggravation of pruritic symptoms and scratching associated with sun exposure. Although we could not find any published reports describing lesions like those of our case, we think that such prurigo nodularis-like porokeratosis can develop in patients with DSAP in some situations involving pruritus and scratching.
