Introduction:Eruptive cutaneous collagenoma is non familial connective tissue nevi of unknown etiology presented with an abrupt onset.To date,the literatures on eruptive cutaneous collagenoma are extremely rare in china.Here,we report two women with eruptive cutaneous collagenoma.Case present:Two women presented with multiple asymptomatic,skin-colored papules and nodules on the trunk and extremities with no systemic involvement.Histopathology revealed dense,coarse collagen fibers by hematoxylin-esoin stain and decreased,fragmented elastic fibers by Elastic stain compared with the normal skin.Basing on these findings,the diagnosis of eruptive cutaneous collagenoma was made.No specific treatment was given.Discussion:Eruptive cutaneous collagenoma is a very rare dermatosis that is often misdiagnosed as other connective tissue nevi.The pathogenesis is unclear,and also no efficient treatment is available.It is usually diagnosed based on clinical and histopathological findings.Conclusion:The present cases are relatively rare type of eruptive cutaneous collagenoma that provide more experience for clinician,and may be helpful for them to make correct diagnosis for suspicious cases.
