Botryomycosis is a rare pyogenic disease that presents with chronic suppurative and granulomatous skin lesions, commonly caused by Staphylococcus aureus. We report a case of botryomycosis presenting similarly to mycetoma, secondary to the emerging cutaneous pathogen Staphylococcus simulans. A 46â€Âyear-old female who previously worked in a wet market presented with a 13-year history of suppurative papules on a gradually enlarging right foot, and pain on ambulation. She had no systemic symptoms or co-morbidities, and does not recall preceding trauma. Physical examination showed brawny edema of the right foot with multiple sinus tracts draining purulent discharge. The clinical diagnosis at presentation was mycetoma. Magnetic resonance imaging showed a soft tissue mass involving the right foot and ankle with osseous destruction. Biopsy revealed suppurative granulomatous dermatitis; staining with Grocott methenamine silver did not highlight fungal elements. Potassium hydroxide mount of the purulent discharge did not show grains or hyphal elements. Tissue cultures showed growth of co-trimoxazole-susceptible Staphylococcus simulans. The patient was managed as a case of botryomycosis and treated with co-trimoxazole for 12 months. There was a significant decrease in right foot circumference along with scarring and resolution of associated pain. Repeat biopsy showed no evidence of infection. This is the first reported case of botryomycosis in the Philippines as well as the first report citing Staphyloccocus simulans as a causative agent. Botryomycosis is an important differential in patients clinically presenting as mycetoma. Animal pathogens may need to be considered as etiologic agents in at-risk patients with chronic subcutaneous infections.

Background and Objective: Scabies is the second most common cause of disability due to skin disease in the Philippines. However, there were no cited studies in Global Burden of Disease 2019 and the disability-adjusted life years (DALY) computations were most likely based on statistical modelling. The Philippine Department of Health has embarked on a program to estimate the disease burden of priority diseases in the country, which include scabies. The last nationwide prevalence survey was 23 years ago. This systematic review aimed to estimate the prevalence or incidence of scabies in the Philippines. Methods: We searched PubMed, Scopus, Herdin, and Philippine Health Research Registry (search date October 2022) for studies on prevalence/incidence (including systematic reviews, cross-sectional studies, cohort studies, case series, registry or census studies) of patients diagnosed with scabies in the Philippines. We excluded narrative reviews, commentaries, and conference proceedings or abstracts. Two reviewers independently screened titles and abstracts, assessed full text reports for eligibility, appraised the quality of included studies, and collected data using a pretested data extraction form. We did not pool studies due to clinical heterogeneity but plotted the individual studies in a forest plot with prevalence estimates and confidence intervals. We reported the median and interquartile range for entire group or relevant subgroups (age, setting) of studies. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to assess the certainty of evidence. Results: We included nine studies (N=79,065). Most were clinic-based prevalence studies, retrospective chart reviews, conducted in dermatology outpatient clinics, Metro Manila area, and on pediatric populations. Prevalence of scabies was moderate (i.e., between 2 and 10%), ranging from 2.75% (national prevalence survey) to 6.8% (communitybased review), to high (> 10%) among pediatric patients in clinic-based retrospective chart reviews (29 to 36%) and institution-based surveys (39.0% to 45%), and a tertiary government university training hospital dermatology clinic (22.9%). The most affected age group was from 0 to 14 y/o, while males tended to have a higher prevalence than females. The cooler month of January had higher prevalence than the hotter month of June in one study. Conclusion Scabies is common in the Philippines, especially among children and elderly in institutional settings, and during the month of January. There is a need to do a national prevalence survey to identify high-risk areas and to monitor the prevalence of scabies, especially in crowded settings and vulnerable populations. This information can be used for estimating the burden of disease for scabies and guide appropriate health resource allocation.
