“… 3 These tumors rarely undergo malignant transformation. 4 Surgical approach for the treatment of orbital schwannomas depends largely on the tumor location; therefore, variation in size and tumor location often creates unique therapeutic challenges.…”

Rare, atypical ophthalmological conditions in adults include bulbar conjunctival plexiform schwannomas, which are usually asymptomatic. Few case reports in the literature indicate the presence of orbital/conjunctival schwannomas in adult patients and, rarely, among children under the age of 12. We report a case of a 5-year-old girl who presented in an outpatient clinic with inferior temporal conjunctival nonpigmented cystic lesion of a 10 × 10 mm size. Upon examination, we could not identify a feeding vessel. The mass was mobile and not fixed to the sclera. The history indicated a 1-year duration but the mass in the left eye had progressively increased in size during the last 2 months prior to presentation. There was no traumatic injury or past history of ophthalmic surgery. Surgical excision of the cyst was sucessfully performed, and histopathological examination confirmed bulbar conjunctival plexiform schwannoma diagnosis. Upon regular follow-up evaluation, there was no evidence of recurrence or malignant transformation. Although it is extremely rare to encounter conjunctival schwannomas in children, it should be considered in ovoidal well-circumscribed orbital swellings, particularly those that appear with no history of trauma or surgery to the eye. Surgical excision is effective and safe therapeutic intervention.

The objective of this study is to report a large, rare, and ulcerative infiltrated skin lesion. Its diagnosis, therapeutic management, and progress are described. The patient is a 78-year-old white man, who presented with a 12-month ulcerative perforated lesion that had affected and infiltrated the skin, with easy bleeding. He had a history of hypertension, although controlled, was a 40-year smoker, had chronic atrial fibrillation, diabetes, and microangiopathy. During the consultation, the patient also presented with ocular obstruction due to an inability to open the eye. He mentioned having reduced vision. The computed tomography scan showed upper maxilla osteolysis without eye involvement. We underwent a radical resection in which upper maxilla and the anterior orbital margin were included. We used a Becker-type flap that allowed us to rebuild the cheek and to complete a modified neck dissection. Progress was favorable; the patient recovered ocular motility and his vision improved to 20/200. The final biopsy result was "malignant peripheral nerve sheath tumor, malignant schwannoma." Malignant schwannoma of the peripheral nerve is extremely rare. The total resection and reconstruction being completed in one surgery represented a challenge due to the difficulty in obtaining tissues in addition to the necessity of an oncological resection.
