A schwannoma is a benign tumor with a neurogenic origin that affects peripheral nerves. It arises from the neural sheath of the peripheral nerves. We present a case of a 54-year-old woman who presented to our clinic with a painful schwannoma of her superficial peroneal nerve at the level of the ankle. The patient was treated with surgical excision, and diagnosis was confirmed with pathologic analysis.

Fibrolipomatous hamartomas of nerve are rare slowly growing fibrofatty masses of peripheral nerves which surround and infiltrate the major nerves and their branches. It may cause symptoms of compression neuropathy. It most commonly affects the median nerve and very rarely involves the lower extremity. Here, we present a very uncommon case of an extensive fibrolipomatous hamartoma at an unusual location in the leg and foot of a young man arising from common peroneal nerve, extending inferiorly along the superficial peroneal nerve in the lateral aspect of leg and foot. We discuss the characteristic radiologic appearance of this entity that is often pathognomonic and allows a confident diagnosis, thus avoiding the need for biopsy.

Schwannomas are benign neurogenic tumors of peripheral nerves that originate from neural sheath. The aim of this case report is to bring to mind the schwannoma in the patient with knee pain. A 39-year-old woman presented with a complaint of knee pain of three months history. After surgical intervention, the patient’s complaints completely disappeared in the post-operative period. This should come to mind in the differential diagnosis of knee pain.

Introduction: Schwannoma is a benign tumor originating from Schwann cells present in the myelin sheath of peripheral nerves. Breast presentation is rare, and its clinical manifestation can mimic that of breast carcinoma. Objectives: To report the case of a patient with breast Schwannoma. Method/Case report: T.S.L., 14 years old, presented a nodule in the left breast (LB) with local growth for 2 months. Ultrasound (US) revealed a cystic formation in the lower outer quadrant of 1.8x1.3 cm, BI-RADS 2. Physical examination indicated a nodular skin lesion next to the LB fold, with 2 cm at 5 h, 7 cm from the nipple. After the surgical excision of the nodule, anatomopathological examination showed a spindle cell neoplasm without nodular-pattern atypia or malignancy characteristics. Immunohistochemistry (IHC) confirmed the Schwannoma diagnosis. Considering this scenario, annual control was started, and the patient has no evidence of the disease after 5 years of diagnosis. Results/Discussion: Schwannoma is a typically benign tumor originating from Schwann cells in the myelin sheath of the nerves. It may result from the parasympathetic or sympathetic division of the autonomic nervous system of the organ. It is one of the few truly encapsulated tumors of the human body and almost always solitary. It is usually located in the trunk, flexor surfaces, retroperitoneum, and rarely in the breast, representing approximately 2.6% of Schwannoma cases. It affects individuals aged 30 to 50 years, with equal incidence in both men and women. The skin lesion presents as a sessile, asymptomatic nodule of 1–3 cm and slow growth. Pain and sensitivity may be present when tumor growth causes nerve compression. Mammography (MMG) shows well-circumscribed opacity, with a density similar to that of soft tissue. US usually reveals well-defined, hypoechoic, solid lesions and can include the target sign, posterior acoustic enhancement, and continuity with peripheral nerves. The definitive diagnosis is made histologically, and the differential diagnosis involves other spindle cell neoplasms, such as fibroadenoma, phyllodes tumor, leiomyoma, fibromatosis, and, rarely, metaplastic carcinoma. Fine-needle aspiration biopsy (FNAB) showed palisading fibrillar cells with non-atypical spindle-shaped nuclei forming Verocay bodies. IHC indicates intense and uniform expression of S-100 protein. Malignant transformation occurs in 3–10% of cases, with high cellular proliferation, atypical mitotic activity, cellular and nuclear pleomorphism, and foci of necrosis. The treatment of choice is surgical excision of the lesion. Tumor recurrence is low and associated with the mitotic index. Conclusion: The case reported and publications found bring to light the discussion on diagnosis and treatment of breast Schwannoma, a rare and benign neoplasm in this location.

Schwannoma is a benign tumor arising from the Schwann cells of peripheral nerves. These are usually benign but malignant transformation can occur in larger lesions. The definitive diagnosis of malignancy can only be made after final histopathological report. The literature reports large pelvic and perineal schwannomas with few being malignant. We report the first case of such giant malignant abdominoperineal schwannoma which was benign on initial biopsy but final histopathology revealed it to be malignant. In view of proximity of perineal and pelvic tumors to urogenital organs and pelvic nerves, such cases represent a challenge to surgical excision. This case brings to highlight another atypical presentation of such tumors.

Rare Benign Tumor

Fibrolipomatous hamartoma is a rare benign tumor characterized by infiltration of fibrous and adipose tissue found within the epineurium and perineurium of the distal peripheral nerves. Most commonly seen in the upper extremities and median nerve, it is rarely involved in the foot and ankle. We report a rare case of fibrolipomatous hamartoma found in the great toe of a 25-year-old patient. Magnetic resonance imaging demonstrated a heterogeneous mass, confirming the mass was solid rather than a fluid collection. Surgical excision revealed a fatty, fibrous, well-demarcated, encapsulated, solid soft-tissue mass. A surgical excision was performed and a pathologic diagnosis of fibrolipomatous hamartoma was made.

Although peripheral nerve injury may result from fractures involving the long bones, bony entrapment of peripheral nerves is infrequently encountered. This report demonstrates a rare case of superficial peroneal nerve entrapment between 2 fracture ends of the distal fibula following a closed ankle fracture resulting from a supination-external rotation mechanism.
