简介:AbstractIntroduction: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.

简介:AbstractIntroduction:Lichen planus pigmentosus inversus (LPPI) is a rare a rare variant of lichen planus characterized by hyperpigmented patches with predominating localization in intertriginous areas. Due to its rarity, only a few LPPI cases are reported. We herein describe two rare cases of LPPI.Case presentation:The two patients were all with a brownish macular lesion on the intertriginous area. A diagnosis of LPPI was made based on their clinical manifestations, dermoscopic features, and histopathologic features, which revealed an interface change, lichenoid infiltration, and pigmentary incontinence.Discussion:LPPI is pruritic or asymptomatic, hyperpigmented macules and patches on the flexural folds. The axillae and flanks were the most commonly affected areas, followed by the groin and genitalia. About half of the female patients had inframammary fold lesions. LPPI shows higher female predominance than Lichen planus pigmentosus. There were fewer cases that lasted more than 3 years compared to LPP.Conclusion:LPPI is a rare variant of lichen planus, with a locational characteristic and female predominance. Therefore, in the case of a pigmented disease occurring in the flexural folds, it should be placed in the differential diagnosis.
