Introduction and importance Soft tissue chondroma is a rare benign tumor with a predilection for hands and feet. The incidence is only about 1.5% of all benign tumors and this neoplasm is rarely seen in the paediatric population. In this paper we report the case of a 14-year-old boy treated for a soft tissue chondroma located next to the left foot second metatarsal. Case presentation A 14-year-old boy presented with a slowly growing plantar swelling of the left foot. The mass was solid, mobile, measuring 4 cm and located in soft tissues opposite of the left foot second metatarsal. Magnetic resonance imaging was performed and revealed a mass measuring 37 ∗ 27 mm with regular seams, on iso-signal T1 and hyposignal T2 without any skeletal connection. A marginal excision of the mass was performed and the postoperative time was uneventful. Clinical discussion The clinical presentation of soft tissue chondroma is generally not specific which makes the diagnosis mostly challenging. Magnetic resonance imaging is the most performed paraclinical examination that allows a better analysis of the lesion. A surgical excision of the tumor is the treatment of choice. Conclusion Soft tissue as a primary site of chondroma is a rarely reported localisation and this neoplasm should be kept in mind as a possible diagnosis face to any plantar mass in childhood.

Introduction and importance ovarian tumors and especially mixed ovarian germ cell tumors are rarely seen in the paediatric population. Case presentation we report the case of a 13-year-old girl which was successfully treated for a mixed ovarian germ cell tumor with a favorable evolution. Clinical discussion the incidence of mixed ovarian germ cell tumors, clinical manifestations, histologic distribution and prognosis are predominentely distinct in children and adolescents as compared to adult population. The diagnosis should be suspected in young girls with chronic abdominal pain and palpable swelling of the lower abdomen. Conservative surgery is the first therapeutic procedure that consists of a total resection of the mass with preservation of the reproductive function. Circulating tumor markers have the potential in diagnosis, prognostic stratification and for follow-up. Conclusion mixed ovarian germ cell tumors are uncommen in children. Their management must be multidisciplinary and conservative surgery by laparotomy represent the standard of care.

We present a case of traumatic neuroma of the common bile duct in a 53-year-old woman who presented with jaundice,5months after cholecystectomy. Physical examination revealed jaundice, epigastric pain and scratching lesions. Gamma glutamyl transferase (GGT) at 109 U/L, Alkaline phosphatase at 175U/L. CA19-9 was at 500U/mlMagnetic resonance cholangiopancreatography revealed a T1 and T2hyperintense lesion of peri-hilar fat. An increase in intensity was noted after useof gadolinium.Exploratory laparotomy was performed with the presumptive diagnosis of cholangiocarcinoma. Pathologic analysis of the surgical specimen revealed Haphazard mature nerves, consistent with a bile duct neuroma. Follow-up of the patient showed no post-operative complications or signs of recurrence.
