Generalized Syringoma: A Case Study

Multiple Scrotal Cysts Composed of Combined Syringomas and Epidermal Inclusion Cysts: A Previously Unreported Association

Epidermal inclusion cyst (EIC) and syringoma are both benign lesions that are primarily asymptomatic and occur at various places on the body. Although both EIC and syringoma are common, their joint appearance has not been previously reported. These benign proliferations target different populations, and with differing clinical presentations. Syringomas tend to develop in young females as smaller multiple lesions, while EICs often present in older males as single or multiple variants that are typically larger in size. They also possess distinctive histopathological appearances that can used for their diagnosis. Furthermore, despite both having unclear etiologies, the involvement of the eccrine duct has been a proposed mechanism in the development of both lesions. Thus, further investigation of eccrine ducts in the pathology of these lesions can be the basis for assessing the association between EICs and syringomas. We report a unique case of a 16-year-old boy who presented to the clinic with multiple cysts (at least 20) on the scrotum, most of which consisted of both EIC and syringoma histologically. We are not aware of any previous reports of patients with multiple combined syringomas and EICs, and their potential association should be further explored.
