Porokeratosis of the penis

Genital porokeratosis: a series of 10 patients and review of the literature

“…Only case reports were found in the literature ( Table 2). [1][2][3][4][5][6] Genital PK is generally classified as classic or plaque-type PM, of which the true incidence is still undetermined. Although the onset of inherited PM is usually during childhood, noninherited cases seem to appear later in life, as seen in our patients and those reported in the literature.…”

“…All of our patients had a noncontributory family history, no immunosuppressed status, and no specific drug history, which was comparable with the cases reported in the literature. [1][2][3][4][5][6] Three of our patients (30%) had diabetes mellitus controlled with oral hypoglycaemic agents. Nine of our patients (90%) presented with pruritic lesions, in contrast to asymptomatic lesions in previously published studies.…”

“…Nine of our patients (90%) presented with pruritic lesions, in contrast to asymptomatic lesions in previously published studies. [1][2][3][4][5][6] We believe that the humid climate in Taiwan might play a role and that repeated trauma (friction or scratching) might explain a part of the pathogenesis of genital PK. Seven of our patients had lesions confined to the genital area, and the other three had involvement of an adjacent area (inguinal area and buttocks).…”

“…Upon review of the English language literature, there were few case reports of PK involving the genital area, and only six case reports (seven patients) of localized PK truly confined to the genital area (genital PK as defined above). [1][2][3][4][5][6] Because of its rarity there is no study on the clinical presentations, associated diseases, treatment and long-term follow-up of genital PK. The purpose of this study was to evaluate the clinical manifestations, histopathology, clinical course and treatment response for genital PK.…”

Genitogluteal Porokeratosis: 10 Years to Make the Diagnosis!

“…So far, less than 40 cases of GGP have been reported in the literature. [1][2][3][4][5]8,[10][11][12][13][14][15][16][17][18][19][20][21][22] A review of these cases revealed common atypical features that may justify considering this entity as a distinct type of porokeratosis. The atypicality manifested at the level of the clinical presentation, clinical associations and course, and even histology.…”
