Abstract
Prepubertal-type teratomas are uncommon, especially in postpubertal male patients. We document a case of a 28-year-old man with a lifelong history of bilateral testicular masses who presented with scrotal fistulas and no clinical evidence of extratesticular disease. Bilateral radical orchiectomies demonstrated large bilateral solid and cystic masses that contained grossly visible hairs. Microscopically, both tumors consisted of pure teratomas comprising a mixture of mature tissues derived from the three embryonic layers. Germ cell neoplasia in situ was not identified, and fluorescence in situ hybridization studies demonstrated the absence of i(12p), supporting a diagnosis of prepubertal-type teratoma. The absence of metastases in this patient with longstanding tumors highlights the benign nature of prepubertal-type teratomas affecting postpubertal patients. Furthermore, this case illustrates that at least a subset of prepubertal-type teratomas seen in adult men represent a late diagnosis of a largely pediatric entity. Additionally, we performed a comprehensive review of the literature on this topic.
期刊介绍:
Manuscripts of original studies reinforcing the evidence base of modern diagnostic pathology, using immunocytochemical, molecular and ultrastructural techniques, will be welcomed. In addition, papers on critical evaluation of diagnostic criteria but also broadsheets and guidelines with a solid evidence base will be considered. Consideration will also be given to reports of work in other fields relevant to the understanding of human pathology as well as manuscripts on the application of new methods and techniques in pathology. Submission of purely experimental articles is discouraged but manuscripts on experimental work applicable to diagnostic pathology are welcomed. Biomarker studies are welcomed but need to abide by strict rules (e.g. REMARK) of adequate sample size and relevant marker choice. Single marker studies on limited patient series without validated application will as a rule not be considered. Case reports will only be considered when they provide substantial new information with an impact on understanding disease or diagnostic practice.
