Conradi-Hünermann-Happle syndrome: Clinical and trichoscopic findings

Conradi-Hünermann-Happle syndrome (CHHS) is a rare genodermatosis resulting from mutations in the EBP (emopamil binding protein) gene. Dermatologic manifestations may include cicatricial alopecia, ichthyosis, follicular atrophoderma, pigmentary abnormalities, and nail dystrophy. In addition to genetic testing and clinical findings, trichoscopic findings may aid in the diagnosis. In this case report, we discuss the trichoscopic findings in a 3-year-old girl with CHHS and how these findings help us understand the pathophysiology of this disease.

[Sevestre-Jacquet posterosive syphilitic dermatitis associated with the use of reusable diapers: A clinical case]

BACKGROUND

Diaper dermatitis is a skin problem that has decreased with the development of new technologies in disposable diapers that prevent excessive moisture in the perianal region. The following clinical case shows the relationship between the use of cloth reusable diapers and the appearance of Jacquet erosive diaper dermatitis, a serious and rare complication of diaper dermatitis.

CLINICAL CASE

We present the case of a 1-year-11-month-old patient, taken to the Dermatology department due to the presence of a lesion in the gluteal region. The mother reported the onset of the condition four months ago after the presence of semi-liquid stools. Localized dermatosis is observed on both lower limbs, affecting the genital region in the labia majora and the perianal region at the level of the intergluteal folds bilaterally and symmetrically. In the histopathological study, a posterosive Sevestre-Jacquet syphilid was diagnosed.

CONCLUSION

Sevestre-Jacquet's posterosive syphilitic dermatitis is a rare dermatological condition and its risk of occurrence is greater due to the use of ecological cloth diapers.
