Purpose: The aim is to study clinical presentations, radiological features and outcome in histopathologically proven orbital schwannomas. Methods: A retrospective and longitudinal study of 16 patients between January 1999 and July 2011 was undertaken by reviewing the appropriate charts. Clinical and radiological data of all orbital schwannomas patients were analyzed. Results: Mean age was 28.18 years (range 8-40 years). Of 16 patients, 10 were males and 6 females. Duration of symptoms was chronic in 15(93%). Chief complaints were proptosis in 10(62.5%), eyelid swelling in 5(31%) and eyelid mass lesion in 2(12.5%). This included a rare case of cystic schwannoma with microphthalmos. Mass was extraconal in 11(69%). Radiological findings varied from solid to cystic, intraconal to extraconal, no enhancement to intense enhancement and presence of calcification. Thirteen (81%) were excised via anterior orbitotomy route while fronto-orbital craniotomy was done in 3(19%). Postoperatively, vision improved or remained stable in 15(94%) and worsened in one (6%). Final visual acuity of 6/6 was achieved in 11(69%), 6/9 in 2, 6/36 in one. Conclusions: Schwannomas may mimic a variety of mass lesions in the orbit because of variable clinical or imaging features and should be considered in the differential diagnosis of all well circumscribed orbital lesions.

“…4 There have been over 10 reports of conventional schwannomas involving the lacrimal gland. [8][9][10][11][12][13][14][15][16][17][18][19] The histologic classification of schwannoma is broken down into subtypes; namely conventional, cellular, malignant melanotic nerve sheath tumor, neuroblastoma-like, ancient, cystic, pseudoglandular, and plexiform. [20][21][22][23][24] The conventional subtype is characterized by both Antoni and B areas, often encapsulated.…”

Plexiform schwannoma of the lacrimal gland of the palpebral lobe has not been previously described. This 41-year-old male presented with a 2-year history of a left upper eyelid mass and associated regional irritation. MRI of the head and orbits confirmed a left superolateral multinodular mass centered on the palpebral lobe of the left lacrimal gland. Excision revealed a schwannoma of the plexiform subtype.

“…3 A Schwannoma of the lacrimal gland is an extremely rare tumor; only 8 previous cases have been described in the literature. [4][5][6][7][8][9] Schwannomas are benign, peripheral nerve sheath tumors, composed of neural crest-derived Schwann cells; they comprise 0.7%-2.3% of orbital tumors. 10,11 It commonly manifests along the supraorbital branch of the frontal nerve.…”

A 60-year-old woman with an asymptomatic left lacrimal gland mass found incidentally

et al. 2017

A 60-year-old woman with a history of recurrent, poorly differentiated adenocarcinoma of the left maxillary sinus was referred to the Orbital Oncology Service of the University of Texas MD Anderson Cancer Center for evaluation and management of a slow growing, asymptomatic left lacrimal gland mass that was incidentally identified on routine surveillance magnetic resonance imaging (MRI). The patient denied significant vision changes, diplopia, and pain associated with the lesion. Other past pertinent oncologic and ophthalmologic history included treatments for the maxillary sinus adenocarcinoma with multiple surgical resections, including a maxillectomy and high-dose radiation of 60 Gy to the nasal cavity and 50 Gy to the right and left neck lymph nodes, and repeated proton beam therapy to the sinonasal region for a local recurrence. The patient’s ocular history was significant for a bilateral dacryocystorhinostomy and left conjunctivodacryocystorhinostomy for nasolacrimal duct blockage and canalicular stenosis secondary to treatments for her sinonasal cancer. Additionally, she was diagnosed with iritis of the right eye 5 months prior to presentation by her local ophthalmologist that had resolved with topical steroids and was felt to be idiopathic in nature.

Schwannomas of the lacrimal gland fossa

Abstract: Two very rare cases of Schwannoma arising within the lacrimal gland fossa are presented, the tumours causing complete atrophy of the normal orbital lobe of the lacrimal gland.
