1. A clinical, dermoscopic, and histopathological study of Dermatosis Papulosa Nigra (DPN) - An Indian perspective. (PubMed)

A clinical, dermoscopic, and histopathological study of Dermatosis Papulosa Nigra (DPN) - An Indian perspective. Dermatosis papulosa nigra (DPN) is a benign cutaneous condition which commonly occurs in dark-skinned people, especially Asians and African Americans. Owing to its benign nature and rarity, very few studies have been conducted to date, and dermoscopic studies are practically nonexistent.To study the clinical and epidemiological characteristics of patients with dermatosis papulosa (...) nigra (DPN) and to correlate the clinical findings with dermoscopic and histopathological findings in DPN.A total of 100 patients attending the Dermatology outpatient department at Father Muller Medical College, Mangalore, India, with clinically diagnosed dermatosis papulosa nigra were included in the study. Histopathology and dermoscopic evaluation of the lesions were done, and the characteristics seen were noted.Earlier onset of lesions was noted in our study, i.e. onset in the 4th decade

Postprocedural wound-healing efficacy following removal of dermatosis papulosa nigra lesions in an African American population: a comparison of a skin protectant ointment and a topical antibiotic. Removal of dermatosis papulosa nigra (DPN) lesions results in superficial cutaneous wounds that are frequently treated with topical antibiotic ointments. We hypothesize that antibiotics are not necessary for effective and safe healing of such wounds.This study compared the wound healing efficacy

FGFR3 and PIK3CA mutations in stucco keratosis and dermatosis papulosa nigra. Stucco keratosis (STK) and dermatosis papulosa nigra (DPN) are referred to as variants of seborrhoeic keratosis. However, the genetic alterations involved in the pathogenesis of these benign tumours are unknown.Because FGFR3 and PIK3CA mutations have been reported to be involved in the pathogenesis of seborrhoeic keratosis, we analysed whether these mutations are also present in STK and DPN.
