Fetal rhabdomyomas (RM) are extremely rare benign mesenchymal tumours that occur primarily in the head and neck.
This tumour exhibits immature skeletal muscle differentiation. The patients’ median age is four years and surgical resection
is the recommended treatment.
Fetal RM of limbs are rare and not well described in the literature and if, predominantly in form of case reports. We report
the second case of a fetal RM in the upper extremity in a 31-year old male patient.
One should be aware of this skeletal muscle tumour and fetal RM should be considered as a differential diagnosis to its
malignant counterpart rhabdomyosarcoma.
