Abstract:
Fibrous hamartoma of infancy (FHI) is a rare, benign soft tissue tumor arising from subcutaneous tissue in children during the first two years of life. The tumor is commonly found in the axilla, shoulder and upper arm. Paratesticular FHI is extremely rare. To date, only a case of paratesticular FHI has been reported in Japan. We present a case of paratesticular FHI in an 11-month-old boy who eventually needed orchiectomy due to local recurrence one month after the excision of the tumor. Ten months postoperatively, there was no sign of recurrence.

Globular and Fibrous Proteins
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
