A case of schwannoma in breast: A rare site

Schwannomas are slow growing, benign tumors that develop from Schwann cells of peripheral nerve sheath. Breast schwannomas are exceedingly rare, comprising only 2.6% of all schwannomas. This report describes the case of a woman aged 22, who developed a firm, mobile lump in the right breast, initially diagnosed as fibroadenoma. After excision, histopathology study revealed a well-encapsulated, pale white tumor, microscopically portraying interlacing fascicles of spindle-shaped cells, characteristic Verocay bodies and S100 protein immunopositivity, confirming the diagnosis of schwannoma. This case emphasizes the necessity of factoring breast schwannoma in the diagnostic possibilities of palpable breast masses and the necessity of histopathological confirmation following imaging studies.
