Porokeratosis як ҳолати нодири пӯст аст, ки бо мушкилоти кератинизатсия тавсиф мешавад, ки дар натиҷа часбҳои баланд, ҳалқашакл ё зарбаҳои ноҳамвор дар пӯст ба вуҷуд меоянд. Хусусияти муайянкунандаи он дар назди микроскоп мавҷудияти ламеллаи cornoid, сохтори мушаххаси ҳуҷайраҳо дар қабати болоии пӯст мебошад. Porokeratosis дар шаклҳои гуногун меояд (disseminated superficial actinic porokeratosis, classical porokeratosis of Mibelli, porokeratosis palmaris plantaris et disseminatum, linear porokeratosis) . Бояд қайд кард, ки porokeratosis метавонад ба саратони пӯст табдил ёбад. Беҳтарин роҳи ташхис porokeratosis ин тавассути биопсияи сарҳади баланд аст, гарчанде ки дар айни замон протоколи стандартии табобат вуҷуд надорад.
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) бемории кератинизатсияи вайроншуда мебошад. Ин яке аз шаш намуди порокератоз аст ва он одатан нисбат ба дигар минтақаҳои калонтар таъсир мерасонад (linear, Mibelli's, punctate, palmoplantar disseminated, superficial porokeratosis) . Навъи таркиши порокератоз аксар вақт ба саратон, иммунитети заиф ё илтиҳоб алоқаманд аст. Омилҳои хавф аз генетика, фишори масуният ва таъсири офтоб иборатанд. DSAP ҳамчун доғҳои гулобӣ ё қаҳваранг бо кунҷҳои баланд дар минтақаҳои офтобӣ оғоз меёбад, ки баъзан боиси хориши каме мегардад. Табобатҳо гуногунанд ва метавонанд кремҳои маҳаллӣ, терапияи рӯшноӣ ё доруҳо ба монанди 5-фторурасил ё ретиноидҳоро дар бар гиранд. Ин захмҳо пеш аз саратон ҳисобида мешаванд ва 7. 5 - 10 % имкони мубаддал шудан ба карциномаҳои ҳуҷайраҳои сквамозӣ ё ҳуҷайраҳои базавӣ мебошанд.
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.

Марди 52-сола, ки қаблан солим буд, дар охири ангушти чоруми ангушти ҳамвор ва ҳалқашакле, ки 2 сол боз дар он ҷо буд, бе ягон нишона ворид шуд. Он ҳамчун як зарбаи хурд ва сахт оғоз ёфт ва бо мурури замон ба берун калон шуд. Сарфи назар аз кӯшиши табобатҳои гуногун ба монанди криотерапия, кремҳо, антифунгҳо ва антибиотикҳо, ямоқи беҳтар нашуд. Ҳангоми бо дермокопсия бодиққат тафтиш кардани он маркази хушк ва сурх бо сарҳади ғафси ноҳамворро нишон дод. Як пораи ночизи пӯст, ки аз канори патч гирифта шудааст, афзоиши ғайримуқаррарии ҳуҷайраҳоро дар қабати берунии пӯст нишон дод, ки ташхиси porokeratosis of Mibelli ро тасдиқ мекунад.
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.

Аксар вақт биопсия анҷом дода мешавад, зеро он метавонад ба кератози актинӣ ё карциномаҳои ҳуҷайраҳои сквамӣ монанд бошад.
