Fulltext Metastatic malignant schwannoma of orbit: a case report

Jaais F, Sivanesan S

Med J Malaysia, 1986 Dec;41(4):356-60.

A case of metastatic malignant schwannoma of the right orbit is presented here. Although the patient had disseminated disease, it was the eye problems which were striking and most symptomatic.
The orbital lesion was at first thought to be the primary tumour until a history of an excised right wrist mass was probed into and the histology traced.
This report is written as malignant schwannoma is an uncommon tumour. The difficulty in diagnosing malignant schwannoma is mentioned. The importance of diagnosis of an orbital metastatic lesion is also pointed out as this is often misdiagnosed.

To describe a case of isolated infraorbital mass which had been present for the past 9 years in a young woman. Despite the size, the mass was successfully excised in total.

Ophthalmic Plast Reconstr Surg, 2008 3 22;24(2):147-8.

PMID: 18356724 DOI: 10.1097/IOP.0b013e31816746b4

A 5-month-old girl presented with a soft-tissue mass over the lateral aspect of her right eyebrow. Surgical resection revealed a diagnosis of infantile malignant hemangiopericytoma. The mass recurred after excision and reconstruction. The patient died 4 months later with brain and lung metastasis.

Benign chondroid syringoma of the orbit: an atypical location

Yap JF, Madatang A, Hanafi H

Orbit, 2020 Apr;39(2):135-138.

PMID: 31023118 DOI: 10.1080/01676830.2019.1604766

A 31-year-old male with no known medical illness presented with painless left eye protrusion for the past 2 years. Radiographic features were of an extraconal superior orbital mass with no invasion of adjacent structures. The patient underwent an excisional biopsy of the left superior extraconal mass a week later. The histopathological examination revealed a well-circumscribed lobulated mass with chondroid and myxoid stroma enveloping benign bland-appearing epithelial and myoepithelial cells. These pathological features were consistent with benign chondroid syringoma of the orbit. The patient had an uneventful recovery with no active ocular complaint post-operatively.Despite chondroid syringoma of the orbit being a rare tumour, it should be considered in the differential diagnosis of periorbital masses. Excision of the tumour remains the treatment of choice with histopathological examination as the gold standard of diagnosis. Regular follow-up is warranted in view of possible local recurrence or metastasis.

Benign orbital apex tumors treated with multisession gamma knife radiosurgery

Goh ASC, Kim YD, Woo KI, Lee JI

Ophthalmology, 2013 Mar;120(3):635-641.

OBJECTIVE: The orbital apex is an important anatomic landmark that hosts numerous critical neurovascular structures. Tumor resection performed at this complex region poses a therapeutic challenge to orbital surgeons and often is associated with significant visual morbidity. This article reports the efficacy and safety of multisession gamma knife radiosurgery (GKRS) in benign, well-circumscribed tumors located at the orbital apex.

DESIGN: Retrospective interventional case series.

PARTICIPANTS: Five patients with visual disturbances resulting from a benign, well-circumscribed orbital apex tumor (3 cases of cavernous hemangioma and 2 cases of schwannoma).

METHODS: Each patient treated with GKRS with a total radiation dose of 20 Gy in 4 sessions (5 Gy in each session with an isodose line of 50%) delivered to the tumor margin.

MAIN OUTCOME MEASURES: Best-corrected visual acuity, visual field changes, orbital imaging, tumor growth control, and side effects of radiation.

RESULTS: All patients demonstrated improvement in visual acuity, pupillary responses, color vision, and visual field. Tumor shrinkage was observed in all patients and remained stable until the last follow-up. No adverse events were noted during or after the radiosurgery. None of the patients experienced any radiation-related ocular morbidity.

CONCLUSIONS: From this experience, multisession GKRS seems to be an effective management strategy to treat solitary, benign, well-circumscribed orbital apex tumors.

Orbital multiple myeloma: a diagnostic challenge

Orbital involvement in multiple myeloma is unusual. We describe the case of an 85-year-old woman who presented with right eye proptosis, reduced visual acuity and diplopia. Computed tomography showed a lobulated, enhancing soft tissue mass arising from the right greater wing of the sphenoid with intraconal, lacrimal gland and ocular muscle involvement. Histopathology revealed predominantly atypical plasma cells in a background of reactive lymphocytes, with monoclonality towards kappa light chain protein, suggestive of multiple myeloma. This case illustrates the diagnostic imaging challenge of orbital multiple myeloma.

Orbitofacial dermatofibrosarcoma protuberans with intranasal extension

Sharudin SN, Tan SW, Mohamad NF, Vasudevan SK, Khairan H, Mun YC, et al.

Orbit, 2018 Jun;37(3):196-200.

PMID: 29058523 DOI: 10.1080/01676830.2017.1383474

A 25-year-old Chinese woman presented with recurrent painless swelling over the left medial canthus region for 3 months and intranasal mass for an indeterminate duration. Initial incision biopsy of the mass was reported as nodular fasciitis but the lesion recurred 3 weeks later. Intraoperative findings during repeat biopsy showed a mass extending from the deep dermal tissue into the anterior orbit and polyp-like nasal mass. Histopathology findings were that of dermatofibrosarcoma protuberans (DFSP). The mass recurred 4 months later without orbital or intranasal recurrence. Wide excision biopsy under frozen section guidance was attempted however; clear surgical margins could not be achieved despite extensive resection. She was subsequently referred for adjuvant radiotherapy. We report an exceptionally rare case of local recurrence of DFSP in an unusual anatomic location. This case was surgically challenging in achieving negative margins, and thus neoadjuvant therapy may improve overall outcome to prevent local relapse.

Orbital rhabdomyosarcoma in an HIV positive child

Khairy-Shamel ST, Shatriah I, Adil H, Zunaina E, Bakiah S, Rohaizan Y, et al.

Orbit, 2008;27(5):388-90.

PMID: 18836940 DOI: 10.1080/01676830802336629

We reported a case of orbital rhabdomyosarcoma with an intracranial extension in an HIV-infected child. It was an uncommon sarcoma in a retroviral-positive patient that resulted in a diagnostic and therapeutic dilemma. The child is currently asymptomatic following surgery, chemotherapy, and reinstitution of highly active retroviral therapy (HAART).
