ABSTRACT To describe 2 patients with orbital invasion by maxillary ameloblastoma, a rare odontogenic tumor that is not commonly encountered in ophthalmic practice.
Retrospective, interventional case report.
Two patients who were diagnosed with maxillary ameloblastoma several years ago sought treatment for new-onset ocular and orbital signs and symptoms.
Clinical and radiological findings and outcome.
In the first patient, tumor recurrence with orbital invasion was diagnosed, and the patient underwent a total orbital exenteration. No recurrence was noted after 18 months of follow-up. The second patient had intracranial involvement with orbital invasion and underwent an extensive resection through an intracranial approach. No recurrence was noted after a 6-month follow-up period.
Although a slow-growing tumor, maxillary ameloblastoma can recur after surgical excision and can be locally aggressive; it can invade the orbit and result in significant ocular morbidity. Ophthalmologists should be aware of this tumor and should monitor these patients closely when orbital invasion is suspected.

    ABSTRACT: Ein 66-jähriger Patient mit vorausgegangener ausgedehnter Exzision und Bestrahlung eines maxillären Ameloblastoms stellte sich mit einem Rezidiv des Tumors vor. Klinisch zeigte sich eine Infiltration der knöchernen Orbita und des intraorbitalen Weichteilgewebes sowie der Nasennebenhöhlen und Schädelbasis. Die histologische Untersuchung des exzidierten Gewebes bestätigte die Diagnose eines Ameloblastoms. Es zeigte sich eine starke Expression von CD56 in den Tumorzellen. Obwohl das Ameloblastom gemeinhin ein niedrigmaligner Tumor ist, werden zuweilen lokal aggressive Formen beobachtet.

    ABSTRACT: A 66-year-old man with a history of repeated surgery, external radiation and brachytherapy for ameloblastoma presented with a recurrence of the tumor with sinus, intraorbital and skull base infiltration. Histopathologic examination of the resected orbital and sinus tissue confirmed the diagnosis of ameloblastoma. Immunohistochemical staining for CD56 was strongly positive in the tumor cells. Although ameloblastoma is usually a low-grade malignant tumor, it can be locally aggressive with invasion of the surrounding tissue. Maxillary ameloblastomas are more likely to infiltrate the orbit.

    ABSTRACT: Anticonvulsant hypersensitivity syndrome is an adverse drug reaction usually occurring from 1 to 8weeks after exposure to antiepileptic drugs. It can threaten life by affecting the liver, kidneys, central nervous system or lungs. We present a 47-year-old patient treated with phenytoin, lamotrigine and clobazam for 7years. He presented with hepatic and renal failure in relation to this syndrome demonstrated by renal biopsy. Prognosis was excellent due to an early diagnosis leading to cessation of the causative agents. Levetiracetam was started with a good response.
