title: Reticular schwannoma mimicking myxoid sarcoma.
abstract: Reticular/microcystic schwannoma is a recently described rare distinctive variant of schwannoma with a predilection for gastrointestinal tract. Its occurrence in soft tissue is extremely rare. We report a case of reticular/microcystic variant of schwannoma in a 55-year-old Indian woman who presented with a painless slow-growing swelling in the right forearm for the past 6 months. MRI findings suggested myxoid sarcoma. However, histological and immunohistochemical findings in the excised specimen were consistent with reticular/microcystic variant of schwannoma. This case report emphasises that the diagnosis of reticular/microcystic schwannoma should always be considered in cases where myxoid sarcomas are suspected as it can mimic malignant myxoid sarcomas, clinically and radiologically, thereby avoiding aggressive intervention and overtreatment.
