Atypical cutaneous findings of <scp>hand‐foot‐mouth</scp> disease in children: A systematic review
Bibliographic record
Abstract
INTRODUCTION: Hand-foot-mouth disease (HFMD) is a common childhood infectious disease. Atypical skin findings of HFMD, often associated with coxsackievirus A6 (CVA6), were first reported in 2008, with increasing reports worldwide since. Atypical lesions of HFMD often involve sites beyond the palms and soles and tend to have unusual, polymorphic morphology. METHODS: A systematic review was conducted on clinical features and outcomes of pediatric HFMD with atypical cutaneous manifestations. RESULTS: Eighty-five studies were included, representing 1359 cases with mean age 2.4 years and a male predominance of 61%. The most reported morphologies were vesicles (53%), papules (49%), and bullae (36%). Other morphologies included eczema herpeticum-like (19%), purpuric/petechial (7%), and Gianotti Crosti-like (4%). Common atypical sites included the arms and/or legs (47%), face (45%), and trunk (27%). CVA6 was identified in 63% of cases. Symptoms resolved in a mean of 10 days. Overall, 16% of cases received treatment, most commonly with acyclovir, intravenous antibiotics, or topical steroids. The most common complications were nail changes (21%) and desquamation (4%) which occurred a mean of 3 and 2 weeks after symptoms, respectively. CONCLUSION: Due to unusual morphologies resembling other conditions, HFMD with atypical cutaneous findings may be misdiagnosed, leading to inappropriate and unnecessary investigations, hospitalization, and treatment. Greater awareness of atypical presentations of HFMD is warranted to improve patient care and counseling on infection control precautions.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
