Abstract
Primary pituitary lymphoma (PPL) is an extremely rare localized lymphoma without systemic involvement. The most common clinical presentations of PPL are hypopituitarism, headaches, and ophthalmoplegia. Diagnosing PPL without a biopsy is almost impossible. There is no study that has specifically investigated and reviewed treatment responses to the ophthalmological symptoms of PPL patients. Herein, we present a 66-year-old female patient who had acute-onset total ophthalmoplegia and headache as admission symptoms, which was diagnosed as PPL after subtotal resection. In the present study, we discussed the response of ophthalmological symptoms to treatment with a review of the literature. Only 18 reported cases had postoperative ophthalmological examination, and in 94.4% of these cases, ophthalmoplegia resolves after surgery and chemotherapy. The complete resection rate of the PPL in the literature was found to be as low as 12.3% in this region because of the hard and adhesive nature of the tumor. Our review unveiled that complete recovery of ophthalmoplegia can be achieved even in the late phase of the symptoms. In the present case, ophthalmoplegia resolved completely following subtotal resection and rituximab, high-dose methotrexate, and cytarabine treatment.

Abstract
Primary pituitary diffuse large B-cell lymphoma (PPL) has been regarded as a subtype of primary central nervous system lymphoma (PCNSL); however, the pituitary gland is located outside the blood brain barrier (BBB) with neural and vascular connections to the brain. Given its unique anatomic location, a combination of non-central nervous system (CNS)-penetrating and CNS-penetrating therapeutic agents can be employed to treat PPL. We report a female patient with PPL who was successfully managed with anatomy-adapted therapy incorporating non-CNS penetrating chemoimmunotherapy [rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP)] alternating with CNS-penetrating chemoimmunotherapy [rituximab, high-dose methotrexate, and high-dose cytarabine (RMA)]. She received a total of eight cycles of treatment with four cycles of each regimen following partial transsphenoidal resection. She achieved a complete response after two cycles and has remained in complete remission for the last eight years. To our knowledge, this is the longest documented survival in a patient with PPL. Targeted genomic profiling with Next-Generation Sequencing (NGS) was recently performed on the lymphoma tissue. The genomic profile of PPL in this patient is quite different from the findings typically associated with PCNSL. We suggest that PPL may be biologically distinct from PCNSL and should be treated with an anatomy adapted approach. Additional research is necessary to confirm our findings.

Abstract
Human immunodeficiency virus (HIV) can have profound impact on the function of the pituitary gland. We have performed an electronic literature search using the following database: PubMed, Medline, Scopus, and Google Scholar. These databases were searched using the keywords HIV, pituitary glands, cancer, pituitary apoplexy, and infertility. HIV can cause hypopituitarism and also can lead to diabetes insipidus. The impact can be slow and insidious, and diagnosis depends on high index of clinical suspicion. The effect on anterior pituitary gland can be associated with growth hormone deficiency, hypothyroidism, adrenal insufficiency, premature menopause, erectile dysfunction, and infertility. HIV can cause pituitary apoplexy, and this should be treated as an endocrine emergency. Importantly, HIV can be associated with pituitary lymphoma and pituitary cancer. Therefore, joined management between HIV physicians, clinical biochemists and endocrinologists may help in establishing pituitary dysfunction.

Abstract
OBJECTIVE Differential diagnosis of nonadenomatous sellar masses causing hypopituitarism is still a challenge. Among these masses, growing evidence has demonstrated that primary pituitary lymphoma is a specific and emerging entity. The aim of our study was to describe our experience with a case of primary pituitary lymphoma and to perform a review of the available literature. METHODS We searched relevant databases up to March 2020, identifying 36 suitable articles basing on inclusion criteria (primary pituitary lymphoma in adult immunocompetent subjects). Overall, 43 cases were included in the review, adding a new case diagnosed and treated in our hospital. Epidemiologic data, clinical presentation, hormonal status, radiologic findings, pathology, treatment, and outcome were extracted. RESULTS Mean age at diagnosis was 58.9 years, without gender difference. Symptoms related to mass were common (52.3%), in particular cranial nerve palsy (70.5%), headache (56.8%), and alteration in visual field (40.9%). Impaired hormonal status was detected in 89.7% of patients; of them, 58.9% presented with anterior pituitary failure (partial or total), while 25.6% presented with panhypopituitarism. Overall, diabetes insipidus was present in 30.8% and hyperprolactinemia in 41.0% of patients. The majority of patients presented a radiologically invasive mass in the suprasellar region and cavernous sinus (65.9% and 40.9%, respectively) and histologic diagnosis of diffuse B-cell lymphoma (54.5%). CONCLUSION The differential diagnosis of sellar and parasellar masses causing hypopituitarism should include primary pituitary lymphoma, even in absence of systemic symptoms or posterior pituitary dysfunction. The disease has a heterogeneous pattern, so a collaboration between endocrinologists, neuroradiologists, neurosurgeons, and hematologists is desirable.

Abstract
PURPOSE Primary central nervous system lymphoma (PCNSL) involving the hypothalamic-pituitary axis (H-P axis) is a rare intracranial neoplasm. We aimed to determine the unique characteristics and treatment outcomes of patients with PCNSL at the H-P axis and review the literature. METHODS We retrospectively reviewed the electronic medical records of patients with PCNSL in our institute from 2000 to 2017. We analyzed patient characteristics, clinicopathologic features, imaging results, and treatment outcomes. Furthermore, we searched the PubMed database and gathered more cases from published studies to analyze patient treatment outcomes. RESULTS A total of 488 patients were diagnosed with central nervous system lymphoma at our institute. Seven (1.4%) patients had H-P axis involvement, five had diffuse large B-cell lymphoma, and two had mucosa-associated lymphoid tissue lymphoma. All patients had anterior pituitary lobe dysfunction, and two had posterior lobe dysfunction. The median progression-free survival (PFS) for seven patients was 29.0 (range: 0.9-48.1) months, and the 3-year survival rate was 42.9%. Pooled analysis included 45 patients. The median PFS for these patients was 7.0 months (0.9-52.0), and the 2-year survival rate was 20%. Univariate and multivariate analyses revealed that the patients with visual field defects had better prognosis (p = 0.0153 and 0.043, respectively). CONCLUSION PCNSL at the H-P axis is associated with a higher rate of pituitary dysfunction than other parasellar pathologies. PCNSL at the H-P axis has a worse treatment outcome than PCNSL at other sites. However, visual field defect is related to a favorable prognosis in these patients.

Abstract
Pathologies involving the pituitary stalk (PS) are generally revealed by the presence of diabetes insipidus. The availability of MRI provides a major diagnostic contribution by enabling the visualization of the site of the culprit lesion, especially when it is small. However, when only an enlarged PS is found, the etiological workup may be difficult, particularly because the biopsy of the stalk is difficult, harmful and often not contributive. The pathological proof of the etiology thus needs to be obtained indirectly. The aim of this article was to provide an accurate review of the literature about PS enlargement in adults describing the differences between the numerous etiologies involved and consequent different diagnostic approaches. The etiological diagnostic procedure begins with the search for possible other lesions suggestive of histiocytosis, sarcoidosis, tuberculosis or other etiologies elsewhere in the body that could be more easily biopsied. We usually perform neck, thorax, abdomen, and pelvis CT scan; positron emission tomography scan; bone scan; or other imaging methods when we suspect generalized lesions. Measurement of serum markers such as human chorionic gonadotropin, alpha-fetoprotein, angiotensin converting enzyme, and IgG4 may also be helpful. Obviously, in the presence of an underlying carcinoma (particularly breast or bronchopulmonary), one must first consider a metastasis located in the PS. In the case of an isolated PS enlargement, simple monitoring, without histological proof, can be proposed (by repeating MRI at 3-6 months) with the hypothesis of a germinoma (particularly in a teenager or a young adult) that, by increasing in size, necessitates a biopsy. In contrast, a spontaneous diminution of the lesion is suggestive of infundibulo-neurohypophysitis. We prefer not to initiate steroid therapy to monitor the spontaneous course when a watch-and-see attitude is preferred. However, in many cases, the etiological diagnosis remains uncertain, requiring either close monitoring of the lesion or, in exceptional situations, trying to obtain definitive pathological evidence by a biopsy, which, unfortunately, is in most cases performed by the transcranial route. If a simple surveillance is chosen, it has to be very prolonged (annual surveillance). Indeed, progression of histiocytosis or germinoma may be delayed.

Abstract
Primary pituitary lymphoma (PPL) represents an extremely rare entity. Here, we have reported two recently identified cases of immunocompetent PPL having diffuse large B-cell lymphoma by surgical biopsy. Both patients had hypopituitarism, with one patient developing right ptosis. In both patients, MRI and FDG-PET/CT depicted sellar mass that extended into the cavernous sinus with the right sphenoid also present in one of the patients. No systemic disease was found in these two patients. Surprisingly, we found that both patients had infiltrative lesions in sphenoid sinus mucosa pathologically, but the sphenoid bones that composed the sellar base were visually intact during the biopsy procedure. Chemotherapy was administered to both patients, where one patient achieved remission at the recent follow-up, whereas the other one did not respond to the treatment. The diagnosis of PPL is usually difficult if solely dependent on history, clinical presentation, biochemical indexes, and radiographic findings. We have also updated and reviewed the epidemiologic features, clinical presentations, pathological characteristics, potential mechanisms, therapeutic orientation, and prognostic advances of PPL. A total of 40 cases (including ours and four pediatric patients), histologically diagnosed, were analyzed in terms of clinical presentation, endocrine abnormality, radiological features, pathology, treatment, and follow-up. Hypopituitarism and headache were the most common presentation of PPL, while diabetes insipidus was reported in 13 patients (43.3%). B cell lymphoma was the most common type of pathology, followed by T-cell and NK/T cell. PPL was more invasive in nature at the suprasellar region (72.5%), cavernous sinus (52.5%), and sphenoidal sinus (27.5%) in 29, 21, and 11 patients, respectively. Pediatric patients with PPL seem to be different compared to their adult counterparts in terms of pathogenesis, clinical presentation, and radiological features. The management of PPL usually follows the treatment protocols for PCNSL but has a poor prognosis compared to the pituitary involvement of systemic lymphoma.

Abstract
Primary extranodal non-Hodgkin's lymphomas (EN-NHL) are a heterogeneous group of malignancies that involve numerous entities with significant difference in terms of tumor site locations, prognostic factors, biology expression, and therapeutic options. In the literature, many EN-NHL types were reported from limited series which only allowed narrow views for elucidating prognostic factors and defining the role of loco-regional therapies in the era of new systemic and biologically targeted therapies. The Rare Cancer Network (RCN), an international multidisciplinary consortium, has published a number of reports on several EN-NHL sites which included many gland locations. In this review, we will focus on the recent literature for a selected number of EN-NHL types in both exocrine and endocrine gland locations. We aim to provide renewed and clear messages for the best practice in 2019 for diagnosis, histopathology, treatments, and also their prognostic implications. We believe that better understanding of molecular and genetic characteristics of these particular diseases is crucial for an appropriate management in the era of personalized treatment developments.

Abstract
Primary intracranial lymphomas (Weller et al. in Neuro Oncol 14(12):1481-1484, 2012) are an emerging disease and an isolated localization in the pituitary gland i.e. primary pituitary lymphoma (PPL) represents a rare condition. We present an update of the most recent evidence for PPL through a systematic review of the literature. A systematic literature review was conducted using PubMed database up to October 2015. The population was defined as immunocompetent patients with a pathologically confirmed diagnosis of PPL. Patients' characteristics, clinical presentation, radiological features, pathology reports, adjuvant treatment and follow-up data were analyzed. We reported one case of PPL and included our data in this analysis. A total of 33 cases of PPL were identified, including ours. A slight not significant female prevalence was evident, with a mean age of 59 years at diagnosis. Visual troubles and headaches were the most common presenting symptoms. About 80 % of patients presented a cranial nerve (CN) deficit. The most frequently involved were the II and III CN. Anterior hypopituitarism was present in 70 % of cases and a diabetes insipidus in 36 % of cases. PPL was rarely limited to the sella and most often extended to the suprasellar and parasellar space. 70 % of cases underwent resection, 21 % a biopsy. A B-cell lymphoma was isolated in 82 % of cases, a T-cell lymphoma in 15 % and a NK/T cell lymphoma in one case. Overall mean survival rate was 14.4 months (95 % confidence interval 9.0-19.8 months) and there was no difference in terms of survival rates when patients were stratified according to the treatment they received. PPL is an emerging clinical entity. Literature data are too scarce to allow the definition of specific protocols of treatment and the management is based on the guidelines present for PCNSL. The role of surgery aiming at a complete resection of PPL should be reevaluated in wider studies including only this category of patients, to establish the real role of each therapeutic strategy.
