Fibrous hamartoma of infancy (FHI) is an infrequent benign proliferation of the soft tissues. Ninety one percent of cases occur during the first year of life. FHI is characterized as a subcutaneous lesion with characteristic morphology with a triphasic organoid growth pattern.
We present the case of a 6-month-old male infant with a tumor in the medial plantar region of the left foot, which was completely withered. Histopathological study reported a fibrous hamartoma of infancy.
Fibrous hamartoma of infancy most frequently affects males. It may be localized at any anatomic site, although 5-10% of cases affect the lower limbs. Few cases are reported in the foot. This is a lesion with a characteristic morphological pattern; however, in small biopsies, its differential diagnosis is important with other fibroadipose lesions for appropriate treatment. Ample surgical resection with lesion-free borders confers a good prognosis for these patients.
婴儿纤维性错构瘤（FHI）是一种罕见的软组织良性增生。91%的病例发生在出生后第一年。FHI的特征是皮下病变，具有特征性形态，呈三相类器官生长模式。
我们报告一例6个月大的男婴，其左脚内侧足底区域有一个完全萎缩的肿瘤。组织病理学研究报告为婴儿纤维性错构瘤。
婴儿纤维性错构瘤最常累及男性。它可位于任何解剖部位，尽管5% - 10%的病例累及下肢。足部报道的病例较少。这是一种具有特征性形态模式的病变；然而，在小活检中，与其他纤维脂肪性病变进行鉴别诊断对于恰当治疗很重要。进行无瘤边界的充分手术切除可为这些患者带来良好预后。
