This afternoon with  pleasent company and help of my colleague  Dr. Francsico  Javier Garcia Martinez (Last year Resident Dermatologist Santiago de Compostela  ) we have had an interesting case.

CLINICAL CASE

A 5 old year girl complained about plantar pain an nodule for  6 months.

The plantar nodule was evident and increased and decreased depending on weeks.

An ultrasound of the painful area was performed

COMMENT OF CUTANEOUS US

• A dermal-subdermal hyperchoic structure, surounded by a hypoechoic halo,  with posterior shadowing was evident.

• Suspicion diagnosis of foreign body was stabished. Mother was explained about observation or extraction and conservative approach was adopted

TAKE HOME MESSAGE

• Ultrasound is useful in the diagnosis of subcuraneous lesions
• Artifacts as posterior acoustic shadowing are useful when establishing siagnosis of slid foreign bodies
• Follow up and foreign body extraction is easier guided by ultrasound
