Sporotrichoid Primary Cutaneous Nocardiosis: A Rare Case of Isolated Upper-Limb Involvement in a Housewife.

Nocardiosis is a rare infection due to a ubiquitous, gram-positive, weakly acid-fast, filamentous, aerobic bacteria, that are usually responsible for opportunistic infection in immunocompromised patients. Less frequently, nocardiosis can affect immunocompetent patients, causing primary cutaneous infections. Here we present a case of a 45-year-old housewife with a 12-day history of red painful nodules arranged linearly on her right upper limb, without any apparent history of injuries or comorbidities, albeit with a hobby of gardening.

Pigmentary demarcation lines over the face.

Background: We have been observing that a significant proportion of our patients, especially females, have certain pigmentary demarcation lines (PDL) over the face. However, systematic studies of the subject are lacking.

Aims: We categorized the different clinical patterns of facial PDLs in the Indian subpopulation and assessed their prevalence in this study.
