Malignant conjunctival melanoma is a rare tumor. A 46-year-old woman with a history of locally recurrent left conjunctival melanoma was followed by F-FDG PET/CT. Four years after the local recurrence treated by orbital exenteration, the follow-up PET/CT scan showed an incidental intense FDG uptake mass infiltrating the gallbladder associated with a low uptake of an infracentimetric pulmonary nodule. The patient was completely asymptomatic with no sign of local recurrence. Laparoscopic cholecystectomy was performed, and histopathologic findings were consistent with gallbladder metastasis of melanoma...

OBJECTIVES/HYPOTHESIS: Inverted papillomas (IPs) are benign tumors of the sinonasal tract with a malignant transformation potential. Predicting the transformation propensity of IPs and corresponding risk factors has long been a challenge. In this study, we aimed to use radiographic findings on magnetic resonance imaging (MRI) and computed tomography (CT) to help differentiate IP from IP-transformed squamous cell carcinomas (IP-SCC). STUDY DESIGN: Retrospective cohort study...

Eyelid reconstructions are considered challenging surgical procedures, which are mostly performed due to trauma, tumor resections, and congenital defects. Several techniques can be used to reconstruct the lower eyelid defects. In this study, the authors aimed to introduce a new single-step technique for the reconstruction of medium-sized lower eyelid defects while preventing ectropion. A modified nasojugal flap was designed and harvested after making a complete incision. A dermal extension from the nasolabial area was added to the end of the nasojugal flap...

Protein arginine methyltransferase 7 (PRMT7) is a member of a family of enzymes that catalyze the transfer of methyl groups from S-adenosyl-l-methionine to nitrogen atoms on arginine residues. Arginine methylation is involved in multiple biological processes, such as signal transduction, mRNA splicing, transcriptional control, DNA repair, and protein translocation. Currently, 10 patients have been described with mutations in PRMT7. The shared findings include: hypotonia, intellectual disability, short stature, brachydactyly, and mild dysmorphic features...

Lacrimal sac tumors are rare and difficult to diagnose. We present a case of coexisting lacrimal sac adenocarcinoma and transitional cell carcinoma in a 73-year-old woman who presented with swelling of the inner canthus. Biopsy identified the growth as an adenocarcinoma. After dissection of the lacrimal carcinoma via a lateral rhinotomy, histopathologic examination confirmed the adenocarcinoma and identified a coexisting transitional cell carcinoma. A recurrence developed, but only of the adenocarcinoma component...

Introduction  Surgical treatment of petrous apex chondrosarcoma is challenging due to the location of the tumor. Using an endoscopic technique for tumor resection is favored since it provides a minimally invasive approach. Case Presentation  A 57 years old female was admitted for acute onset of left abducens nerve palsy and occasional headache mainly on the left side of the retro-orbital area with some radiation to the left occiput. Magnetic resonance imaging (MRI) and computed tomography (CT), at the time of admission, were showed lytic lesion on the left petrous apex and left part of the clivus...

We present a case of bilateral synchronous orbital muscle infiltration of extra-neural glioblastoma metastases with evidence of focal treatment response. The orbital infiltration was preceded by evidence of leptomeningeal disease, and followed by further symptomatic perineural spread of tumor along the second and third division of the trigeminal nerve and into the masticator space.

Cavernous hemangioma of the orbit (CHO) is a benign slow-growing lesion of intracanal space. Bilateral orbital cavernous hemangiomas are extremely rare, so that only a few cases have been reported in scientific literature. A 54-year-old patient presented a 1-year history of impaired visual acuity of the left eye. Physical examination showed a left axial propotosis. Orbital magnetic resonance imaging showed a 28 mm diameter intraconal space mass of the left orbit, as well as another 11 mm diameter lesion in the right eye, in the superomedial extraconal space...

Fibromyxomas are rare tumors that are not commonly seen in the orbit. The authors present a case of orbital fibromyxoma. A 42-year-old male presented with proptosis of the right eye that began 1 month prior. Magnetic resonance imaging revealed the presence of an orbital mass in the right eye, with low signal intensity on T1-weighted images and heterogeneous high-signal intensity on T2-weighted images. The patient underwent excisional biopsy of the orbital tumor through a Krönlein approach. The tumor originated from the inferior rectus muscle...

BACKGROUND: Cancers of the paranasal sinuses are rare tumors that tend to be aggressive and usually are diagnosed at an advanced stage. Despite being rare, these tumors include a wide spectrum of histological subtypes with different biological behaviors. Choosing the optimal treatment modalities and analyzing the different oncological outcomes is therefore challenging. This study aims to evaluate the role of induction chemotherapy prior to definitive local therapy for sinonasal malignancies...

Although orbital tumors involving the optic nerve are rare, it is well-known that they are very likely to cause serious visual impairment in a patient. Unfortunately, at present, there are no effective interventions that can reliably preserve visual function while controlling tumor growth into intracranial spaces. To ensure visual function of the non-affected side, transection of the optic nerve together with the tumors involved is necessary in some cases. For this procedure large craniotomy and orbital unroofing are commonly utilized...
