We report a case of a non-Hodgkin's lymphoma in a young woman presenting with an abdominal mass and an unusual instance of cranial nerve palsies mimicking Gradenigo's syndrome. This condition is characterized by a triad of otorrhea, facial pain and diplopia, related to otitis media in the pre-antibiotic era. Incomplete and atypical clinical features of Gradenigo's syndrome have been described and noninfectious causes may mimic this condition. Careful clinical history and physical examination, including neuroimaging, are necessary to make a differential diagnosis.

Exophthalmus is the leading sign of space-occupying lesions of the orbit. Patients may further present with lid swelling, impaired ocular motility and optic neuropathy including a relative afferent pupillary defect, compressive optic disc edema or optic atrophy. Orbital tumors can be classified into various categories depending on the etiology, as lymphoproliferative lesions (in particular non-Hodgkin's lymphoma as the most common malignant orbital tumor of adulthood), optic nerve and meningeal lesions, lacrimal gland lesions, secondary orbital tumors which extend to the orbit from neighboring structures and metastases. Slightly less common are vasculogenic and cystic lesions including cavernous hemangioma as the most common benign orbital tumor of adulthood and dermoid cysts as the most common benign orbital tumor of childhood. Rhabdomyosarcoma is the most common malignant orbital tumor of childhood but has a low total incidence. Orbital tumors might not only cause symptoms like pain, diplopia and loss of visual acuity but may also lead to esthetically disfiguring changes. Particular attention should be paid to underlying systemic diseases and generalized tumor diseases. This article illustrates the approach to a detailed clinical and neuroradiological assessment which is mandatory for the care of orbital tumor patients.

Paraneoplastic cerebellar degeneration (PCD) is a type of paraneoplastic neurological disorder (PND) that is associated with many solid tumors, Hodgkin's lymphoma (HL) and very rarely with non-Hodgkin's lymphoma (NHL). We report a case of PCD associated with gastric diffuse large B-cell lymphoma (DLBCL) in a patient who presented with acute onset of giddiness and double vision and had complete remission of the gastric lesion and marked improvement of cerebellar syndrome with rituximab-based combination chemotherapy. A brief review of the literature is also presented.

Objective:To investigate the clinical manifestation, imaging and histological features of different histological subtypes of non-Hodgkin's lymphoma of nasal cavity and paranasal sinuses.Method:Fifteen NHL patients of the sinonasal region were collected from the Department of Otolaryngology of Peking University Third Hospital from 2010 to 2016. HE staining and immunohistochemical staining were performed. The clinical characteristics and imaging features of different subtypes were described and analyzed.Result::We analyzed a total of 6 patients with localized sinonasal diffuse large B cell lymphoma and 9 patients with localized sinonasal extranodal NK/T cell lymphoma. The age distribution for these two subtypes is very distinct. The median age of the patients with localized sinonasal extranodal NK/T cell lymphoma was 39 years. There were 5 males and 4 females. Nine sinonasal NHLs were NK/T-cell lymphoma, nasal type, all of which were infected with EBV. The median age of the patients with localized sinonasal diffuse large B cell lymphoma was 64 years. There were 3males and 3 females. Symptoms for patients with SN-DLBCL and SN-ENKTL were significantly different in epiphora, proptosis, diplopia and nasal congestion (P=0.18, 0.004, 0.18, 0.18). Imaging features for patients with SN-DLBCL and SN-ENKTL were significantly different in tumor extended to orbit and inferior turbinate (P>0.05). Positive staining for CD 56 was detected in 9 patients, for CD 3 in 9 patients, for EBER in 9 patients. The Hans algorithm identified 1 patient with the germinal center B-cell (GCB) subtype and 5 with the non-GCB subtype.Compared with the control group, the observation group was significantly better than the control group (P < 0.01).Conclusion:Early symptoms of epiphora, proptosis, diplopia, and images finding with orbital invasion should be highly suspected of diffuse large B cell lymphoma. Positive staining for CD 56 and EBER were detected in all patients with extranodal NK/T cell lymphoma, and positive staining for CD20 was detected in all patients with SN-DLBCL.

Mantle cell lymphoma (MCL) is a form of non-Hodgkin's lymphoma originating from mature B cells. The hallmark gene translocation (11:14) results in overexpression of cyclin D1. Affected extranodal sites include bone marrow and gastrointestinal tract, but skin, orbit or CNS are rarely involved. Twenty-four cases have reported involvement of skin by MCL, while orbital MCL is equally rare. Our case is the first to report relapsed MCL with involvement of the skin and orbit simultaneously without disease in the lymphatic system or the bone marrow. A 53-year-old female with stage IV MCL initially presented with pancytopenia, adenopathy and splenomegaly. She achieved complete remission after six cycles of rituximab and bendamustine. Within 4 weeks of treatment, she developed diplopia and a rash of the left breast. Skin biopsy showed lymphoma infiltrates with B-cell markers for MCL. MRI of the orbits and brain suggested orbital lymphoma. CSF cytology further confirmed MCL cells. At time of relapse, she continued to be in hematologic remission. She initiated intrathecal cytarabine and methotrexate along with ibrutinib. R-CHOP was then added to the regimen. Within 2 weeks of starting treatment, her skin disease resolved and she had improvement in vision. MCL commonly presents as a disseminated disease, resulting in high mortality. Involvement of the skin or orbit has been sparingly reported and always suggests aggressive disease. It thus poses a challenge to diagnose and treat the condition as evidenced by resolution of adenopathy and bone marrow disease. Due to the overall poor prognosis of MCL and its unique presentations, as demonstrated by our case, early detection and prompt treatment are crucial to survival.
