ReferencesPorokeratosis rara est condicio cutis quae per difficultates keratinizationis designatur, unde in inaequaliter resorptione vel in cute aspera labefactatur. Eius lineamentum, quod sub microscopio apparet, est lamella cornoidea, dispositio certarum cellularum in strato superiore cutis. Porokeratosis in varias formas venit (disseminated superficial actinic porokeratosis, classical porokeratosis of Mibelli, porokeratosis palmaris plantaris et disseminatum, linear porokeratosis). Gravis est notare quod porokeratosis potest evolvere in carcinomam cutis. Optima via ad curandam porokeratosim est per biopsiam terminorum elevatorum, quamquam nullum protocolum curativum adhuc exstat.
Porokeratosis is an uncommon dermatologic disorder. It is a disorder of keratinization that presents with keratotic papules or annular plaques with an elevated border. It has a distinct histologic hallmark of cornoid lamella, which is a column of tightly fitted parakeratotic cells in the upper epidermis. There are multiple clinical variants of porokeratosis, including disseminated superficial actinic porokeratosis, classical porokeratosis of Mibelli, porokeratosis palmaris plantaris et disseminatum, and linear porokeratosis. Porokeratosis is a precancerous lesion that can undergo malignant transformation. Evaluation of porokeratosis is best with a biopsy of the elevated border. There are no standard guidelines for treatment.

Disseminated superficial actinic porokeratosis (DSAP) morbus est keratinizationis inordinatae. Una ex sex generibus porokeratosis est et typice afficit areas maiores quam ceterae comparatae (linear, Mibelli's, punctate, palmoplantar disseminated, superficial porokeratosis). Genus eruptivum porokeratosis saepe coniunctum est cum cancro, immunitate labefactata, vel inflammatione. Factores periculi includunt geneticos, immunosuppressionem, et expositionem solarum. DSAP incipit quasi maculae roseae vel fuscae, cum margine elevato, in locis solis expositione, interdum parvum pruritum provocans. Curationes variantur et includunt applicationem crepitum, therapias lucidas, vel medicamenta sicut 5‑fluorouracil vel retinoids. Haec laesiones precancerosae sunt, cum periculo 7.5‑10 % conversionis in carcinoma squamatosum vel basocellulare.
Disseminated superficial actinic porokeratosis (DSAP) is a disease of disordered keratinization. Disseminated superficial actinic porokeratosis is one of six variants of porokeratosis. It has more extensive involvement than most other variants. These other variants include linear porokeratosis, porokeratosis of Mibelli, punctate porokeratosis, porokeratosis palmaris et plantaris disseminata, and disseminated superficial porokeratosis. The eruptive form of porokeratosis is associated with malignancy, immunosuppression, and a proinflammatory state. Risk factors for porokeratosis include genetics, immunosuppression, and ultraviolet light. The lesions in disseminated superficial actinic porokeratosis start as pink to brown papules and macules with a raised border in sun-exposed areas that can be asymptomatic or slightly pruritic. There are many options for the treatment of disseminated superficial actinic porokeratosis, including topical diclofenac, photodynamic therapy (PDT), 5-fluorouracil (5-FU), imiquimod, vitamin D analogs, retinoids, and lasers. These lesions are considered precancerous. There is a 7.5 to 10% risk of malignant transformation to squamous cell carcinoma or basal cell carcinoma.

Homo, LII annos natus, antea sanus, venit cum plano, anulo informato panni in fine quarti pedis, quod ibi fuerat per duos annos sine ulla symptomate. Incēpit parva, dura, gibba, quae in tempore externo crevit. Quamvis varias curationes temptavit, ut cryotherapy, crepito, antifungalia et antibiotica, commissura tamen non melius proficiebat. Arcte examinans per dermocopiam, ostendit mediam siccam, rubram, cum margine crasso et aspero. Minima particula cutis ex margine commissurae ostendit incrementum cellularum abnormalium in strato cutis externi, confirmans diagnosis porokeratosis of Mibelli.
A 52-year-old man with no past medical history presented with an asymptomatic annular atrophic patch on the distal portion of the fourth toe of 2 years’ duration. The lesion began as a small keratotic papule that gradually enlarged centrifugally. He had received multiple treatments including cryotherapy, topical corticosteroids, antifungals, and antibiotics without improvement. Dermoscopic examination revealed a scaly atrophic erythematous central area with a sharply demarcated peripheral hyperkeratotic structure. A skin biopsy of the edge of the lesion revealed a cornoid lamella with a column of parakeratotic cells extending from an invagination of the epidermis with absence of granular layer. The clinicopathologic correlation was consistent with porokeratosis of Mibelli.

Saepe fit biopsia, quia potest videri simile carcinomatis keratosi actinici vel squamosi.
