中文摘要 | 足部壓力性丘疹臨床上為足後跟膚色丘疹,在站立及施壓下會更明顯。成因是足跟的脂肪組織因壓力而疝出至周圍的結締組織基質中而形成丘疹。我們報告一個51歲女性,在足跟內外側有許多膚色丘疹,並會引發疼痛。病理檢查發現脂肪組織周圍的膠原纖維變得較疏鬆,而作Verhoeff-Van Gieson染色更發現整個網狀真皮的彈性纖維有顯著的減少。我們的個案在病理切片的變化類似皮膚鬆弛症,而臨床上則是典型的足部壓力性丘疹,因此推測皮膚鬆弛症的彈性纖維缺失可能造成足部壓力性丘疹,相關的文獻提及結締組織小樑的彈性纖維缺失與此疾有關,而我們的病例則是網狀真皮層彈性纖維明顯減少,與其相比並不相同。我們在此提出一位足部壓力性丘疹的病例,並探討組織病理變化與相關可能原因。 |
英文摘要 | Piezogenic pedal papules are skin-colored lesions on the heels caused by herniation of fat through the connective stroma. They are induced by weight bearing or pressure to the soles. We report a case of a 51-year-old female who had multiple painful skin-colored papules on the medial and lateral aspects of the left heel when applying force on it. Microscopically, the collagen bundles of the trabeculae around the fat lobules were looser than normal. Verhoeff-Van Gieson stain revealed a remarkable decrease in the elastic fibers in the reticular dermis. The pathologic picture was similar to that of anetoderma. Few articles referred to the absence of elastic tissue in the connective tissue trabeculae rather than in the reticular dermis in our case. We herein report a case of piezogenic pedal papules and discuss the clinical, histopathologic change, and related etiologies. |
