A unique case of subcutaneous panniculitis-like T-cell lymphoma presenting as an abscess following an arthropod bite.

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare form of low-grade cutaneous lymphoma that usually presents with multifocal non-tender subcutaneous nodules over the trunk and extremities. We present an exceptional case of SPTCL masquerading as a solitary abscess which developed following an antecedent arthropod bite. Unique histological features encountered include foci of neutrophilic aggregation and admixed eosinophils within the neoplastic lymphomatous subcuticular infiltrate. As SPTCL rarely presents as an abscess, the authors wish to highlight this diagnostic pitfall and suggest excluding SPTCL as a cause of pseudo-pyoderma in patients who are afebrile with a discordant inflammatory marker profile. In addition, this condition should be suspected in non-diabetic patients who experience a rapid clinical course with suppuration and demonstrate a poor response to appropriate antibiotics. As such, we recommend sending tissue for histopathological examination for patients with atypical presentations.

Epidemiology of occupational dermatoses associated with personal protective equipment use in the COVID-19 pandemic: Risk factors and mitigation strategies for frontline health care workers.

Background: Personal protective equipment (PPE)-related occupational dermatosis (PROD) represents a significant occupational burden to health care workers (HCWs), and understanding its epidemiology is imperative in formulating mitigation strategies. Objectives: To determine the prevalence of PROD in HCWs, characterize its manifestations, identify its risk factors, and evaluate behavioral modifications of HCW. Methods: A cross-sectional study using an online questionnaire was conducted from July to September 2020. HCWs who had direct contact with COVID-19 patients for a minimum of 2 weeks cumulatively were invited to participate. Results: The prevalence of PROD among 416 valid respondents was 73.8% (307/416), with face masks being the most common cause (93.8% [n = 288]). The most common PROD associated with face masks, protective eyewear, hairnets, gowns, and gloves were acne (71.5% [206/288]), pressure-related injuries (70.7% [99/140]), scalp itch (53.3% [16/30]), itch/rash (78.8% [26/33]), and xerosis (75.0% [27/36]), respectively. Exposure to PPE beyond an hour increased the odds of PROD by 4.8-fold. The majority of HCWs made behavioral modifications to mitigate PROD. Conclusions: We underscore evidence-based recommendations for HCWs to be (1) scheduled hourly breaks from PPE wear, (2) fitted to various PPE models, (3) screened for preexisting dermatoses before deployment, and (4) educated on mitigation strategies and avenues for help should they encounter PROD.
