Pediatric Diffuse Large B-Cell Lymphoma of the Frontal Sinus: A Case Report

An 11-year-old male presented with right proptosis, bulbar conjunctivitis, and diplopia. Computerized tomography (CT) and magnetic resonance imaging revealed an enhancing mass involving the superio-medial orbit, ethmoids, frontal sinus, and anterior cranial fossa with skull base destruction. Diffuse large B-cell lymphoma was diagnosed via CT-guided biopsy. As a component of multidisciplinary care, the patient underwent frontal sinus cranialization, with orbital and skull base reconstruction. Trauma reconstructive principles guided recreation of orbital, frontal sinus, and anterior skull base anatomy. This rare primary location is undescribed in the pediatric literature.

Primary diffuse large B-cell lymphoma of the ethmoid sinus: a case report

B-cell lymphoma of the paranasal sinuses is rare. We present the case of a 42-year-old woman who presented with proptosis, diplopia, and vision disturbances in the right eye. She was diagnosed with diffuse large B-cell lymphoma of the ethmoid sinus. We describe the general clinical presentation, diagnosis, and differential diagnosis of this entity, and we review the pathology of diffuse large B-cell lymphoma.

Recurrent Periorbital Cellulitis: An Unusual Clinical Entity

OBJECTIVES: To discuss the cause and management of recurrent periorbital cellulitis (RPOC).

STUDY DESIGN: Retrospective case series and review of literature.

MATERIALS AND METHODS: In the past 11 years, we have treated 6 patients for recurrent periorbital cellulitis (RPOC). Inclusion criteria were a minimum of 3 episodes of periorbital cellulitis (POC) within a 1-year period, with interval convalescence lasting at least 1 month. All patients were followed for at least 1 year after resolution.

RESULTS: The causes of RPOC were as follows: (1) 2 patients developed RPOC attributed to environmental allergies; (2) 1 was diagnosed with underlying recurrent sinusitis resistant to medical management with resolution attained through surgery; (3) 1 patient with vesicular RPOC was diagnosed with herpetic RPOC and treated medically with antiviral therapy; (4) 1 patient had allergic contact dermatitis from cosmetic make-up use; and (5) 1 patient was suspected of malingering via repeat subcutaneous self-injection of an irritant.

CONCLUSIONS: Although periorbital cellulitis is a commonly encountered and treatable condition, recurrent periorbital cellulitis is rare and may be challenging to manage. In our experience, the causes of recurrence varied, but resolution was achieved by identifying the underlying cause through continuous clinical reassessment and by appropriate medical or surgical management.

Recurrent periorbital cellulitis in a very young child: a case report and review of literature

Recurrent periorbital cellulitis is a rare complication of sinus disease. We present a 4-month-old boy with bilateral recurrent periorbital cellulitis and radiological evidence of bilateral bony dehiscence of the lamina papyracea. To our knowledge, this is the youngest documented presentation of recurrent periorbital cellulitis. As well, only unilateral cases have been reported in the past. In addition to the clinical case report, we reviewed the current literature available regarding recurrent periorbital cellulitis.

Frontal sinus lymphoma presenting as progressive multiple cranial nerve palsy

Primary frontal sinus lymphoma is a very uncommon disease. In all the previously reported cases, the presenting symptoms have been due to the tumor mass effect. We present an unusual case report of an immunocompetent patient who presented with facial palsy, and then progressively developed other cranial nerve palsies over several months. He was later diagnosed with diffuse large B cell lymphoma originating from the frontal sinus. The patient underwent chemotherapy, but eventually had to receive autologous peripheral blood stem cell transplantation. He is currently disease-free. The clinical course, diagnostic workup, and therapeutic outcome are described.

Recurrent unilateral periorbital cellulitis in a pediatric patient--an anatomic abnormality

A 2-year-old male, otherwise healthy, suffered a total of 7 episodes of recurrent right-sided periorbital celluitis (POC) which began at 11 months of age. Five of the 7 episodes of right eye swelling/erythema required hospital admission for intravenous antibiotics. Imaging studies demonstrated a well-defined dehiscence in the lamina papyracea. Endoscopic sinus surgery was performed and an abnormal uncinate process was visualized, fused to the lateral nasal wall and ethmoid bulla. Post-operatively, the patient had no further infections. Nasal endoscopy and high-resolution imaging in pediatric patients with recurrent POC could identify those who would benefit from early surgical intervention.

Orbital and periorbital infections

Infections of the orbit and periorbital tissues are not uncommon. Trauma, skin infections, and sinusitis are frequently the underlying cause. Studies have shown changes in epidemiology and pathogens in the last decade. Although classical manifestations are usually present, atypical cases without specific signs and symptoms may confound the diagnosis. A high index of suspicion, aided by ultrasonography, computed tomography, and magnetic resonance imaging, is frequently required for an accurate diagnosis. Prompt diagnosis and treatment may lead to resolution of the infection, thus avoiding ocular sequelae. Orbital infections may spread into the globe, causing endophthalmitis. Some patients may even need an enucleation or evisceration. New materials and techniques may improve the final result of an anophthalmic socket.
