Inflammatory Myofibroblastic Tumour of the Sinonasal Tract with Orbital and Intracranial Extensions Simulating a Malignancy: A Case Report and Review of Literature.

Inflammatory Myofibroblastic Tumour (IMT) is a rare pathology of unknown etiology. It is pathologically benign, but clinically locally invasive. We are herewith reporting a unique case of rapidly growing sinonasal IMT with orbital and intracranial extensions in a middle aged female patient masquerading as a malignancy. The lesion was excised endoscopically with margins and the patient is presently under close follow up. The report also reviews the common sites of involvement and management options available, based on a literature review.

Clinical image: Rare photographic documentation of uveal melanoma progression.

To present clinical images of a patient with neovascular glaucoma and hypermature cataract masking orbital extension of a uveal melanoma. Observations: A 67-year-old female was referred for neovascular glaucoma and found to have an intraocular tumor with massive orbital extension. She refused surgery and returned one year later with progression of the tumor with metastases and expired seven months later. Conclusions and importance: Unexplained glaucoma and cataract should be investigated for harboring underlying intraocular tumors to prevent delays in diagnosis. Providers also should obtain greater understanding of psychosocial and socioeconomic barriers to healthcare.

Visual Outcomes in Spheno-Orbital Meningioma: A 10-Year Experience.

BACKGROUND: Spheno-orbital meningiomas (SOMs) present distinct surgical challenges because they involve important neurovascular structures, such as the orbit, cavernous sinus, superior orbital fissure, and optic canal. Resection thus focuses on maximum safe resection while preserving these neurovascular structures. Our objective was to describe our method of surgical management of SOMs and summarize visual outcomes. METHODS: A retrospective chart review was performed to identify patients who underwent surgery for SOM in 2011-2021. Demographics, preoperative visual summary, operative details, visual outcomes, and recurrence data were collected. RESULTS: The 33 patients (10 male, 23 female) had a mean age of 56 years (range 27-74 years). The mean tumor volume was 39 mL (range 4.7-220 mL). The mean follow-up period was 18 months (range 1-120 months). Thirty-two patients had preoperative radiographic evidence of proptosis (based on exophthalmos index), 23 (70%) presented with diminished visual acuity, and 10 (30%) had a concomitant visual field deficit. At last postoperative follow-up, vision was stable for 25 patients (83.3%), improved for 1 (3.3%), and worsened for 3 (10%; 2 occurring after tumor recurrence beyond 2 years). Proptosis was stable or improved in all patients. One patient had an enucleated eye. A total of 7 patients (21%) had recurrence of the tumor at 19-72 months from the operation. CONCLUSIONS: In this study, maximum safe resection, including periorbital resection, provided adequate visual and cosmetic outcomes, as well as reasonable tumor control in the long term. Rigid orbital reconstruction was not required to prevent pulsatile enophthalmos.

Recurrent corneal hemangiosarcoma in a cat with subsequent extension into the orbit.

A 7-year-old neutered female Domestic Short-haired cat was presented for evaluation of ulceration and severe vascularization of the left cornea. Ophthalmic examination revealed a large red irregular mass over the whole cornea in the left eye. A lamellar keratectomy was performed. Histopathology revealed a chronic lymphoplasmacytic, histocytic, neutrophilic ulcerative keratitis with fibrosis and vascularization. The tumor recurred within 3 months, and another lamellar keratectomy and sclerotomy were performed. The lesion was diagnosed histopathologically as a hemangiosarcoma with incomplete margins. The mass recurred locally 6 weeks later, and an enucleation was performed. Histopathology revealed infiltration of the limbus and connective tissue beyond the sclera. Seven weeks later, a fluctuant swelling was found in the left orbit. Computed tomography confirmed a soft tissue attenuating mass measuring 33 x 24 mm diameter in the orbit. There was no sign of metastasis. Clinical remission was achieved with combined chemotherapy with doxorubicin and radiation therapy. The patient remained in clinical remission 20 months post-chemotherapy.

Orbitofacial dermatofibrosarcoma protuberans with intranasal extension.

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.

Frontal Mucocele Mimicking a Frontal Subcutaneous Tumor.

Mucoceles are chronic, expanding, mucosa lined pathology of the paranasal sinuses. Frontal mucocele usually presents with the visual complaints such as diplopia, diminution of vision, visual field defect, ptosis, orbital swelling, retro-orbital pain, displacement of eye globe, and proptosis. Very rarely, it can be present as a subcutaneous swelling. This article presents a 58-year-old male patient presenting with an asymptomatic periorbital swelling and a painless forehead mass of 3 years duration. There was a partial ptosis, and an elongated, soft, subcutaneous mass over the forehead. Surgical excision of the mass confirmed the diagnosis of a mucocele. Postoperatively, the patient was asymptomatic. A subcutaneous soft-tissue mass may be the presenting complaint of a frontal mucocele. Careful examination of the surrounding skin may suggest the diagnosis of sinus-related disease and thus direct appropriate investigations.

Giant Orbital Melanoma in a Heroin Abuser.

PURPOSE: The aim of this report was to report a heroin abuser with nondiagnosed giant uveal melanoma infiltrating the orbit and prolapsing through the face. METHODS: We conducted a case report of the patient with giant melanoma. RESULTS: In March 2013, a 39-year-old male with bleeding from the right side of his face was taken to the Emergency Center of the University Hospital Bratislava by ambulance. The heroin abusing, homeless male who had never been treated before reported a 2-year history of a prolapsed, dark colored mass from his eye. Acute computed tomography confirmed a solid mass 20 × 20 cm prolapsing from the orbit. The patient rejected primary care, accepted only 1 transfusion and left the hospital. Two months later, he was admitted to the hospital due to anemia after many collapses. Liver metastasis was present. Surgical palliative therapy was not possible due to his general status. The patient started fractionated external radiotherapy with 8.0 Gy Co60. Histopathological examination of the biopsy specimen showed malignant melanoma of the epitheloid type G2-3. The patient died in December 2013. CONCLUSION: Extraorbital formation of a melanoma mass may progress to a giant volume, and without treatment, led to metastases in the liver and to death after 9 months in our patient with anemia.

Posttraumatic giant fronto-orbito encephalocele causing cosmetic disfiguring forehead swelling with proptosis: Management.

Fracture of the anterior skull base can occur following head injury. Growing skull fracture is usually observed in children under age of 3-years. It commonly involves frontal and parietal regions. However, orbit involvement is extremely uncommon. Authors report a case of giant orbital encephalocele with a forehead disfiguring swelling in a 4-years boy, who sustained head injury about 3½ years back. However, such delayed presentation of traumatic encephalocele is extremely uncommon and represents the first case in the Western literature, who had a successful postoperative outcome.

Endoscopic removal of a giant ethmoid osteoma with orbital extension.

Osteomas are slow growing bony tumours of the paranasal sinuses. They are usually asymptomatic but they may present with headache, cerebral symptoms, or visual disturbances, depending on their anotomical location. A computerized tomography scan is the imaging modality that should be choosen for the diagnosis of osteomas. Radiographically, osteoid osteoma appears as an opaque lesion with a nidus which has a radioluscent center surrounded by dense sclerosis. If treatment is indicated, external or endoscopic approaches can be chosen. We report a rare case of giant ethmoido-orbital osteoma which was treated via endoscopic approach. The endoscopic way is convenient and safe enough with advantages over the external approach. The decreased morbidity and better cosmetic results are clear advantages of this technique which has the potential to become the treatment of choice for selected ethmoid tumours, such as a giant tumour mentioned in this study.
