BACKGROUND: Trigeminal sensory neuropathy (TSN) describes a heterogeneous group of disorders manifesting as facial numbness. OBJECTIVE: We report the case of a patient who had TSN associated with contact dermatitis due to Anthurium sp. METHOD/RESULTS: A 21-year-old female patient developed left hemifacial contact dermatitis after exposure to the anthurium plant. The patient had paresthesias and pain in the V2 and V3 divisions of the left trigeminal nerve. Eight days after its onset the dermatitis resolved, but numbness developed in the V2 and V3 divisions of the left trigeminal nerve. Cranial CT scan and MRI, as well as CSF and extensive work-up exams, were normal. After one month the symptoms disappeared completely. CONCLUSION: Anthurium sp, an indoor ornamental plant that contains calcium oxalate crystals, and can causes contact dermatitis. To our knowledge, this is the first report associating TSN with contact dermatitis due to Anthurium sp.
INTRODUÇÃO: A neuropatia trigeminal sensitiva (NTS) representa um grupo heterogêneo de doenças, cuja manifestação clínica é a presença de dormência na região facial. OBJETIVO: Relatamos o caso de paciente que apresenta NTS associada com dermatite de contato (DC) devido à planta Anthurium sp. MÉTODO/RESULTADOS: Uma paciente com 21 anos desenvolveu DC na região hemi-facial esquerda, após exposição à planta Anthurium sp. Após a resolução do quadro de dermatite, a referida paciente apresentou dormência e parestesias no território do segundo e terceiro ramos do nervo trigêmeo esquerdo. Um mês após o início do quadro houve resolução completa dos sintomas. CONCLUSÃO: O Anthurium é uma planta ornamental que contém cristas de oxalato de cálcio, que podem causar DC. Para o nosso conhecimento este é o primeiro relato associando NTS e dermatite de contato devido à exposição ao Anthurium sp.

Los schwannomas son tumores de naturaleza benigna o maligna, originados a partir de las células de Schwann de la vaina de mielina de nervios periféricos, autónomos y pares craneanos. Dentro de estos últimos, el nervio trigémino es el segundo en frecuencia en ser afectado. Se presenta el caso de una paciente de 33 años portadora de una neuralgia trigeminal izquierda típica de 4 meses de evolución, con un estudio imagenológico que muestra un tumor originado del nervio infraorbitario izquierdo. Se practica exéresis de la lesión, cuyo estudio histológico revela un schwannoma benigno del nervio infraorbitario. No existen casos con afectación de este nervio publicados a la fecha en la literatura internacional que se ha revisado.
Schwannomas are benign or malignant tumors that arise from Schwann cells in the myelin sheath of peripheral, autonomic or cranial nerves. Among the latter, involvement of the trigeminal nerve is usually the second in frequency. We report the case of a 33 year old patient presenting with a left trigeminal neuralgia of 4 month of evolution. The imaging study showed a tumor of the left infraorbital nerve. The lesion was excised, and the histological study revealed a benign Schwannoma of the infraorbital nerve. To our knowledge, this is the first report of this nerve being affected.

A 46 year old man with trigeminal schwannoma displayed symptoms of ataxia with pathological laughter and crying. The tumour developed in the cerebellopontine angle, compressing the pontomesencephalic structures backward, extending in the posterior parasellar region and Meckel's cave. No recurrence of laughter and crying attacks were noted after total removal of the tumour. Theories of mechanism of pathological laughter and crying reported in the literature are reviewed.
