Background: Parthenium dermatitis is caused by friable plant extracts of Parthenium hysterophorus and related species. Approximately 40% of cases of plant dermatitis in India are contributed by this single species. Materials and Methods: This was a cross-sectional, observational study conducted in the Department of Dermatology of Jhalawar Medical College. Ninety-nine consecutive patch test positive parthenium dermatitis human subjects of age more than 16 and either sex were included. The study period was 11 months between September 2019 and August 2020. Sociodemographic, clinical profile parthenium dermatitis severity score (PDSS) and Dermatology life quality index (DLQI) were obtained from each patient. Correlation between PDSS and DLQI was obtained using Pearson's two-tailed coefficients. Results: Our study included 62 men and 37 women (1.67:1). The mean age was 51 ± 10.27 years. Mean duration of disease was 8.47 ± 4.45 years, and mean PDSS was 57.25 ± 17.65, mean DLQI was 17.14 ± 5.56. ABCD with CAD was the most common clinical subtype (45.45%). A significant positive correlation was observed between PDSS and DLQI. Conclusion: In this study, a significant impairment in quality of life (QoL) was observed in patients with higher score of PDSS and increasing duration, emphasizing that the disease needs specialized care including multiple indoor admission at the time of flare-up of disease.

Computed tomography scan of the head was normal, but magnetic resonance imaging (MRI) brain showed multiple scalp hemangiomas, the largest being in the right posterior parietal region (size 16 mm × 6 mm), while underlying skull vault appears normal [Figure 3]. The red-colored raised lesion initially appeared in multiple mustard size, round, firm lesions, which progressed to almost pea-sized pedunculated lesions in 2-5 days and bled on touch/slightest trauma. There was the presence of a raised solid skin-colored lesion of size 2 cm and rubbery consistency over the right posterior parietal scalp diagnosed clinically as infantile hemangioma.

Plica neuropathica is a rare scalp condition, which is manifested as a compact mass of scalp hair. Previously, it has been found to be associated with a variety of dermatological disorders. We report a case of 15-year-old female presenting with alopecia areata associated with plica neuropathica. [ABSTRACT FROM AUTHOR]
