Malignant peripheral nerve sheath tumour is one of the rare soft tissue tumours in the younger age group. The tumour arises from peripheral nerves with a predominant lesion on the extremities or limbs, head and neck, and trunk. It can arise de novo also known as sporadic or in patients with neurofibromatosis type 1. It is an infiltrative, aggressive tumour with a high rate of recurrence and metastases. The microscopic examination of both NF1 gene-associated and sporadic MPNST are similar but different prognoses aided and abetted by other co-morbid factors or disease conditions. Histologic examination of the surgically resected specimen is the goal standard for diagnosis with an ancillary test comprising immunostaining of the tumour cells. This tumour has the propensity to undergo diverse differentiation towards osseous, chondroblastic, and rhabdomyoblastic cells. The rhabdomyoblastic differentiation is strongly associated with a poor prognosis. Thus, creating a diagnostic challenge for general pathologists and pathologists in the trainee. The specific cause of this tumour is not known but is strongly linked to Neurofibromatosis type 1 in a few groups of patients with multiple cutaneous plexiform neurofibromas which are not concordant with the index case. We, therefore, present a sporadic subcutaneous MPNST with heterologous differentiation comprising rhabdmyoblastic cells, chondroblast, and osseous in a 15-year-old woman.
