ABSTRACT: Soft tissue tumors in the hand have a broad differential diagnosis. Included in the list of differential diagnoses for these tumors are Schwannomas, which are benign tumors within the peripheral nervous system [1]. Schwannomas are uncommon within the upper extremity, and they are exceedingly rare within the hand and wrist [1]. We describe a case of an 80-year-old female presented with a soft tissue mass within her right thumb. She underwent excisional biopsy of the mass, and pathology showed features consistent with schwannoma. She had resolution of her symptoms thereafter. We discuss the differential diagnosis for soft-tissue tumors in this location. When assessing patients with soft tissue tumors of the hand and wrist, it is important for the treating provider to maintain a broad differential diagnosis in order to facilitate appropriate management of these lesions.
