Patients were followed for 3\u20137\u2009years, with follow\u2010up completed in 2024. Diagnosis was clinically suspected by a dermatologist and confirmed histopathologically.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean age at diagnosis was 9.2\u2009years; 59.0% were male. A preceding infection was documented in 60.3% of patients. Disease onset was most frequent in winter (44.9%) and spring (28.2%). Lesions were generalized in 65.4% of patients. PLC was the most common subtype (66.7%), followed by PLEVA (23.1%) and mixed type (10.3%). Histopathologic findings included basal vacuolar changes (88.5%), deep inflammatory infiltrates (83.6%), and parakeratosis (82.1%). Adnexotropism, folliculotropism, and syringotropism were less frequent than previously reported. During 2\u20137\u2009years of follow\u2010up, no patient developed mycosis fungoides. The most common treatments were azithromycin with topical corticosteroids (37.2%) and erythromycin with topical corticosteroids (30.8%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>PL predominantly affects school\u2010age children, shows a male predominance, and often presents in winter. PLC is the most frequent subtype. The absence of progression to mycosis fungoides during long\u2010term follow\u2010up supports the generally favorable prognosis of childhood PL and underscores the value of large pediatric cohorts
