[Differential diagnoses of benign eyelid tumors in children and adolescents].

backgroundThe clinical diagnosis as well as the treatment approach of periocular tumors in childhood and adolescence can be challenging. Knowledge of the most important differential diagnoses and their clinicopathological correlation is helpful for the treatment approach.

objectiveThe clinical and histological characteristics of various eyelid tumors in childhood and adolescence are presented taking the excision frequencies into consideration. MATERIAL AND

methodsThe frequencies and clinicopathologic correlation of the most important eyelid tumors (n = 485) are presented based on the data of the ophthalmopathology laboratory of the University Eye Hospital Bonn from 1998-2023.

resultsThe most frequent tumor in childhood and adolescence is chalazion (57.3%), followed by dermoid cysts (16.7%) and molluscum contagiosum (9.6%). Other lesions of childhood and adolescence include pilomatrixoma (2.1%), hemangioma and other vascular malformations (4.7%) and rare differential diagnoses, such as subcutaneous calcifying nodules and xanthogranuloma. Guidance on the approach in different age groups is presented in the form of a decision tree.

conclusionTumors in children and adolescents are mostly benign, yet there are important indications for excision. A histological examination of any excised tissue in childhood and adolescence is obligatory because unexpected findings are not uncommon and the spectrum of lesions also differs from that in adulthood. Knowledge of the histological picture can be very helpful in the preoperative clinical classification and for planning further procedures.
