Primary non-Hodgkins lymphoma of the lacrimal sac: mortality-related epiphora

Maharajah KR, Hussein A, Mohamad H, Khan SA, At LS

Orbit, 2009;28(5):306-8.

PMID: 19874126 DOI: 10.3109/01676830903044346

We report a case of primary non-Hodgkins lymphoma of the lacrimal sac in a 60-year-old Asian lady, who presented with persistent epiphora and recurrent medial canthal swelling. Primary lymphoma of the lacrimal sac is rare and it can be easily misdiagnosed. Delayed in diagnosis may be related to mortality. To minimize the risk of overlooking specific pathology it is important to assess the appearance of the lacrimal sac and its surrounding structures intraoperatively. Biopsy of the lacrimal sac is required in cases where specific pathology is suspected.

Surgical approaches are becoming increasingly minimally invasive, without compromising either safety or ease. Penetrating ocular foreign bodies has traditionally been approached either by intraocular or supraorbital access. We successfully attempted a minimally invasive approach to remove a retrobulbar foreign body under computer-assisted image guidance in a 19-year-old man involved in an industrial mishap.

Sinusitis is a rare cause of optic neuritis in children. This case illustrates bilateral optic neuritis in a 9-year-old child caused by pansinusitis. It demands an accurate diagnosis with a prompt management. A proper treatment of sinusitis is essential to prevent this complication.

Bilateral ophthalmic vein thrombosis secondary to nasal furunculosis

Rohana AR, Rosli MK, Nik Rizal NY, Shatriah I, Wan Hazabbah WH

Orbit, 2008;27(3):215-7.

PMID: 18569833 DOI: 10.1080/01676830802009754

We were presented with a teenage female who developed superior ophthalmic vein thrombosis and cavernous sinus thrombophlebitis after a 1-week history of a single acne-like lesion or furuncle at the anterior tip of the nose. She was managed aggressively with heparin and intravenous antibiotic. Signs and symptoms improved after 2 weeks of treatment, and she was discharged with an anticoagulant.

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).

Pleomorphic adenoma in the palpebral lobe of the lacrimal gland misdiagnosed as chalazion

Ramlee N, Ramli N, Tajudin LS

Orbit, 2007 Jun;26(2):137-9.

PMID: 17613864

We reported a case of pleomorphic adenoma of the lacrimal gland involving the palpebral lobe in young teenage girl of Asian origin. The presentation at young age group is rare, which initially misdiagnosed as a large chalazion. The benign tumor with its intact pseudocapsule was removed through lateral orbitotomy together with the suspicious looking orbital lobe.

Ocular presentation of sphenoid mucocele

Prepageran N, Subramaniam KN, Krishnan GG, Raman R

Orbit, 2004 Mar;23(1):45-7.

PMID: 15513020

A sphenoid mucocele often presents late due to its deep-seated anatomical site. It has a varied presentation, due to its close relationship to the cavernous sinus and the base of the skull. It can present initially to the ophthalmologist with ocular complaints. In the present paper, the authors present two cases of sphenoid mucocele, one with an isolated third and one with an isolated sixth cranial nerve palsy.

Ethnic variation in deep lateral orbital anatomy and its implications on decompression surgery

Kumaran A, Chan A, Yong K, Shen S

Orbit, 2019 Apr;38(2):95-102.

PMID: 29482415 DOI: 10.1080/01676830.2018.1441316

AIM: To describe differences in the deep lateral orbital wall (specifically, trigone) between Chinese, Malay, Indian and Caucasian subjects Methods: Single-centre retrospective Computed Tomogram (CT)-based study; 20 subjects of each ethnicity were used from existing databases, matched for gender, average age and laterality. Subjects below 16 years of age were excluded. DICOM image viewing software CARESTREAM Vue PACS (Carestream Health Inc., USA) and OsiriX version 7.5 (Pixmeo., Switzerland) were used to measure deep lateral wall length, thickness and volume, as well as orbital depth and statistical analyses performed using Statistical Package for Social Sciences version 21 (IBM, USA).

RESULTS: In each group, there were 12 males (60%) and average age was not significantly different (p = 0.682-0.987). Using Chinese subjects as a reference, in Chinese, Malay, Indian and Caucasian subjects, mean trigone thickness was 13.68, 14.02, 11.60 (p

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.

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.
