Abstract
INTRODUCTION: Schwannoma are benign neoplasms of peripheral nerve sheath. They usually occur in the head, neck and the extremities. Breast is a rare location of Schwannoma. CASE PRESENTATION: Our case describes the occurrence of Schwannoma in the right breast, in a 60-year-old male, who has had a breast lump since the last 6 years. After ultrasonography (showed 3.4 × 2.3 × 2.0 cm heteroechoic mass in the upper outer quadrant of the right breast), and mammography (showed 2.5 × 3.2 cm sized high density mass in upper outer quadrant of right breast), an excisional biopsy was performed, and on histopathologic examination, the diagnosis of breast schwannoma was confirmed. DISCUSSION: Clinical and pathological features resemble that of other benign tumors. On ultrasonography they present a well-defined, solid, hypoechoic mass, with some degree of posterior acoustic enhancement. Diagnosis is usually based on histopathologic examination. Microscopically, it exhibits hypercellular antony A areas along with hypocellular antony B areas. Treatment is usually surgical excision. CONCLUSION: Though Schwannomas in breast are rare, they must be considered as differential diagnoses in patients presenting with breast lumps.
