RESUMO
Abstract Traumatic neuromas are tumors resulting from hyperplasia of axons and nerve sheath cells after section or injury to the nervous tissue1. We present a case of this tumor, confirmed by anatomopathological examination, in a male patient with history of circumcision. Knowledge of this entity is very important in achieving the differential diagnosis with other lesions that affect the genital area such as condyloma acuminata, bowenoid papulosis, lichen nitidus, sebaceous gland hyperplasia, achrochordon and pearly penile papules.

A 70-year-old man with previous cholecystectomy developed progressive obstructive jaundice, 3 months before hospitalization. Intraoperatively, a 2 x 2 x 1.5-cm mass in the distal part of the right hepatic duct was excised to release complete obstruction. It was verified as traumatic (amputation) neuroma. Despite rarity, traumatic neuroma of the bile duct should be considered in patients who have antecedent surgical procedure of the biliary tract with subsequent occurrence of extrahepatic biliary obstruction.

Se comunican tres casos de pseudo-polidactilia que corresponden a tumoraciones congénitas asintomáticas en el tercio proximal del borde ulnar de uno o ambos dedos meñiques. Histológicamente son semejantes a neuromas y es probable que correspondan a neuromas postamputación de verdaderos dedos supernumerarios autoamputados in utero. Los verdaderos dedos supernumerarios presentan falanges e histológicamente no se observa proliferación neural.
