Abrikossoff's tumor mimicking endometrial tumor--literature review and case report of the first described granular cell tumor in scar tissue after caesarean section

Abstract

Abrikossoff's tumor (AT) is a rare, predominantly benign, asymptomatic, solitary, less than three cm-in-size tumor with usually favorable prognosis after surgical excision. Most of the tumors are found in the head and neck location in the third to fifth decade of life. Local wide excision, which is a treatment of choice, is curative in most of the cases.The case of 34-year-old female patient the authors report herein is the first described AT located in scar tissue after caesarean section. Physical and ultrasound examinations revealed a well-circumscribed, two-cm-in-size mass located in the fascia level. With a preoperative suspicion of endometrial tumor, the patient underwent surgery. Tumor was excised with wide tissue margin. Postoperative pathologic analysis revealed the presence of granular cell myoblastoma and was essential giving definitive diagnosis.
