Supraclavicular Solitary Hybrid Schwannoma/Neurofibroma: A Case Report.

Peripheral nerve sheath tumors (PNSTs) are benign lesions arising from the connective tissue sheath surrounding the neurons and are labeled schwannoma, perineurioma, or neurofibroma according to their histopathological characteristics. Lesions with a mixture of two or more of the aforementioned tumors are known as hybrid peripheral nerve sheath tumors (HPNSTs). These hybrid tumors have been described as rare entities. In this report, we present a case of a solitary hybrid schwannoma/neurofibroma in an unusual location.
