| Summary: | Microcystic/reticular schwannoma is a rare variant of
schwannoma with a predilection for visceral locations
including the gastrointestinal tract. Due to overlapping
features with other tumours, unawareness of this
tumour type may lead to diagnostic pitfalls. We here
report a case of microcystic/reticular schwannoma
arising in the mesentery of a 25-year-old female. The
tumour was incidentally discovered by ultrasonography.
An operation was performed and histological
examination revealed a capsulated tumour composed
of spindle cells with reticular pattern set within a
myxoid stroma. Differential diagnoses were Extra
Gastrointestinal Stromal Tumour (EGIST) with
myxoid change, microcystic/reticular schwannoma,
Low-Grade Fibromyxoid Sarcoma (LGFMS) and
Aggressive Angiomyxoma (AAM). Immunohistochemically,
the tumour cells were positive for S-100
protein which was consistent with a peripheral nerve
sheath tumour. Albeit very rare, microcystic/reticular
schwannoma should be included in the differential
diagnosis of mesenteric tumours. The awareness and
the knowledge about this rare tumour are needed to
achieve the correct diagnosis.
