Summary Pemphigus refers to a group of life-threatening, autoimmune blistering disease that presents as blisters and erosions involving the skin and mucosa. Systemic corticosteroids and rituximab have been recommended as mainstay therapy for pemphigus vulgaris and pemphigus foliaceus. Herein, we report three cases of pemphigus vulgaris and a case of pemphigus foliaceus treated with rituximab as first-line therapy.

Summary Phaeohyphomycosis refers to a heterogenous group of mycotic infections caused by dematiaceous fungi where unintentional traumatic inoculation accounts for majority of the cases. Herein, we are reporting a rare case of iatrogenic subcutaneous phaeohyphomycosis which is secondary to intravenous cannula placement.

Background: Adverse reactions on the skin due to face masks are well documented following the COVID-19 pandemic. This study aims to investigate Staphylococcus aureus colonization in relation to face mask-associated adverse cutaneous reactions (FMACR) Methods: This was a case-control study involving adult patients attending dermatology clinic, Hospital Tengku Ampuan Afzan, Pahang, Malaysia. FMACR was determined via a structured interview. Subjects and healthy controls were matched for age and gender. Skin swabs from the alar crease and glabella were obtained and cultured. The possible risk factors for FMACR including type of mask, frequency of change, average duration of use, and skin care practices were also attained. Results: A total of 114 adult participants, which consisted of 57 case and 57 control were recruited. Itching was the most frequent (32; 32.4%) FMACR noted, followed by acne (31; 31.4%) and rashes (22; 22.2%). The presence of facial dermatoses and oily skin type increased the risk of FAMCR (adjusted OR=5.96, 95% CI (1.96,18.12), p=0.002 and adjusted OR=1.94, 95% CI (0.28,13.28), p=0.009) respectively. Cosmetic use was associated with lower risk of FMACR, (adjusted OR=0.16, 95% CI (0.05, 0.56), p=0.004). No significant association was noted between S. aureus skin colonization and FMACR (p=0.409). Conclusion Staphylococcus aureus skin colonization was not associated with FMACR. Risk factors for FMACR were the presence of facial dermatoses and oily skin type while cosmetic use appears to have a protective effect.
