O objetivo é relatar manifestação incomum de linfoma não-Hodgkin de órbita. Paciente masculino, de 75 anos, se apresentou com queixa de lacrimejamento crônico bilateral. Havia feito dacriocistorrinostomia endonasal à direita e à esquerda por duas vezes, sem sucesso. Ao exame, massas de consistência fibroelástica, em topografia das bolsas de gordura das pálpebras inferiores e proptose axial. O paciente negava outros sintomas ou sinais sistêmicos. Hemograma sem alteração, hormônios tireoidianos normais. A tomografia computadorizada mostrava infiltrado difuso na órbita e proptose axial. Biópsia de gordura orbitária e de medula óssea diagnosticaram linfoma não-Hodgkin. O paciente foi tratado com quimioterapia, sendo em seguida submetido à cirurgia da via lacrimal bilateral, com resolução do quadro. A doença sistêmica que exigia diagnóstico e tratamento adequados para que se tivesse bom prognóstico estava mascarada pelo quadro de epífora bilateral.

The complete unilateral cranial nerve paralysis syndrome, or Garcin 's Syndrome, is a rare clinical condition. The purpose of this paper is to describe a case associated with non-Hodgkin s lymphoma. A 41-year-old male patient developed a progressive cranial nerve disorder. On the right hand side, there was impairment of all cranial nerves. We report the clinical and laboratorial findings. Lymph node exeresis revealed a Diffuse Non-Hodgkin s Lymphoma, with diffuse hone marrow infiltration. Cerebrospinal fluid showed pleocytosis, with 100% of immunoblasts. The CT scan showed no tumoral masses on the brain stem. This is the first clinical description of a complete Garcin 's Syndrome caused by diffuse lymphomatous infiltration of the cranial nerves.

Recent reports showed that early-interim PET-scan is the only tool predicting treatment outcome in advanced-stage classical Hodgkin lymphoma (asCHL). We evaluated the prognostic impact of a series of immunohistochemical markers, mentioned in literature as prognostic factors, on tissue microarrays assembled from biopsies of 220 patients: STAT1, SAP, TOP2A, PCNA and CD20, both in neoplastic (HRSC) and microenvironment cells (MC); RRM2, MAD2, CDC2, BCL2, P53, BCL11A and EBER in HRSC; ALDH1A1, TIA-1, granzyme B, perforin, FOXP3, and PD-1 in MC. All patients had been treated with standard ABVD ± Rx therapy. Interim-PET after 2 ABVD courses was evaluated according to the criteria indicated by Gallamini in his study (Journal of Clinical Oncology, 2007). The survival analysis has been performed in a subset of 138 patients whose complete clinical information were available: the mean age was 33.3 years (14-79), the stage III-IVB in 98 and IIB in 40, and the mean follow-up 38.1 months (7.6-71.9). Histopathology review showed: NS-I 75, NS-II 22, MC 20, DL 3, and CHL/nos 18 cases. Interim-PET was positive in 30 patients, while treatment failure was recorded in 32. In univariate analysis the factors related to treatment outcome were BCL2 on HRSC (cut-off value 50%), STAT1/SAP on MC, and PET (Log-rank 6.9, 7.9 and 93.9 respectively). The combined expression of STAT1 and SAP was scored in three levels depending on the architectural pattern: score 0 for expression of both with a diffuse/rosetting pattern; score 1 for discordant combination of diffuse/rosetting and scattered patterns; score 2 for both markers with a scattered pattern; the 3y-PFS were 87.4%, 69.9% and 61.9% respectively. In multivariate analysis PET, BCL2 and STAT1/SAP remained significant (HR: 24.8, 4.6, 7.5 and 5.6, respectively; p<.01). The proposed model is able to predict treatment response in AsCHL, even if with a lower efficacy than PET. However, unlike PET, it can be applied upfront therapy.
