Purpose or Case Report: Skin lesions are not infrequent in children. There is a wide spectrum of lesions and color Doppler High- resolution Ultrasonography plays an important role in the diagnosis. The purpose of this exhibit is to show some skin lesions that can be seen less commonly in this age group, emphasizing the sonographic appearance and clinical and pathological correlation
Methods & Materials: We reviewed retrospectively our experience with Ultrasonography (US) in the study of skin lesions in children for the last eighteen years, including clinical and pathological findings.
Results: All lesions were first examined with US, and in most cases, no additional imaging studies were necessary. Examples of unusual lesions are shown, including congenital myofibromatosis, spiradenoma, septic emboli, subcutaneous fat necrosis, metastatic neuroblastoma, granuloma annulare, pyogenic granuloma, congenital nodular melanocytic nevi, Hashimoto-Pritzker's histiocytosis, juvenile xanthogranuloma, Chilblains, blue nevus, molluscum contagiosum, idiopathic facial aseptic granuloma, precalcaneal congenital fibrolipomatous hamartoma.
Conclusions: High-resolution color-Doppler US plays an important role in the characterization and diagnosis of uncommon skin lesions in children. Although findings might be nonspecific, they may suggest a diagnosis, especially when correlated with clinical findings and could avoid doing other more sophisticated studies, such as MRI.
