Abstract
BACKGROUND Primary nasopharyngeal lymphoma (NPL) is a very rare tumor of Waldeyer ring (WR) lymphoid tissue. It is challenging to differentiate lymphoma infiltration of pituitary from a pituitary adenoma, meningioma infiltration, and other sellar lesions to plan a suitable treatment strategy. We presented for the first time a unique case of NPL with an unusual presentation of oculomotor nerve palsy associated with pan-pituitary involvement in a diabetic patient. CASE PRESENTATION A 64-year old diabetic woman with no previous history of malignancy presented with intermittent diplopia for about the last nine months. Severe headache, left eye ptosis and hypoglycemic episodes were added to her symptoms after a while. Further complaints include generalized weakness, loss of appetite, generalized musculoskeletal pain, and 6-7 kg weight loss within six months. Her family history was unremarkable. Physical examinations of eyes indicated left eye 3rd, 4th, and 6th nerve palsy. But, she was not anisocoric, and the pupillary reflexes were normal on both eyes. No lymphadenopathy, organomegaly and other abnormalities were found. Magnetic resonance imaging (MRI) showed a heterogeneous enhancement in the seller and suprasellar regions, enlargement of the stalk, parasellar dural enhancement and thickening of the sphenoid sinus without bone erosion. Also, both cavernous sinuses were infiltrated and both internal carotid arteries were encased by the neoplastic lesion. It suggested an infiltrative neoplastic lesion which compressed the cranial nerves. Pituitary hormone levels assessment indicated a pan-hypopituitarism. Following nasopharyngeal mucosal biopsy, the immunohistochemistry (IHC) findings revealed a low-grade non-Hodgkin's B-cell lymphoma. Systemic workup, including cerebrospinal fluid (CSF) studies, bone marrow aspiration, chest and abdominopelvic high-resolution computed tomography (HRCT) indicated no other involvement by the lymphoma. After chemotherapy courses, central adrenal insufficiency, partial central diabetes incipidious (CDI) and central hypothyroidism have been resolved. To our best knowledge, we found 17 cases of NPL with cranial nerve palsy, 1 case of NPL with pan-hypopituitarism and no NPL case with both cranial nerve palsy and pituitary dysfunction. CONCLUSIONS The incidence of cranial neuropathy in patients with diabetes should not merely be attributed to diabetic neuropathy without further evaluation.

Postoperative management of patients with pituitary tumors submitted to pituitary surgery. Experience of a Spanish Pituitary Tumor Center of Excellence. Endocrine 2020; 69:5-17. [PMID: 32170587 DOI: 10.1007/s12020-020-02247-y] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Accepted: 02/26/2020] [Indexed: 12/13/2022]
Abstract
There is a lack of evidence on timing, frequency, and duration of postoperative endocrine, radiologic, and ophthalmologic assessments that should be performed after pituitary surgery (PS). However, it is known that careful optimization of treatment and follow-up strategies as well as a multidisciplinary approach may have a significant impact on long-term outcomes, improving surgical results, minimize complications and facilitate their correct treatment if occurring, and optimize the hormonal, ophthalmological, and radiological reassessment throughout the follow-up. Considering that there are no specific guidelines on the postoperative management of patients with pituitary tumors (PT), we present our protocol for the postoperative management of patients with PT. It has been elaborated by the multidisciplinary team of a Spanish Pituitary Tumor Center of Excellence (PTCE) that includes at least one neurosurgeon, ENT, neuroradiologist, neuro-ophthalmologist, endocrine pathologist and endocrinologist specialized in pituitary diseases. We elaborated this guideline with the aim of sharing our experience with other centers involved in the management of PT thereby facilitating the postoperative management of patients submitted to PS.

Abstract
Prolactin is a major hormone, involved in gonadotroph axis regulation. Hyperprolactinemia induces gonadotropin deficiency and therefore hypogonadotropic hypogonadism. It should be suspected in front of menstrual cycle abnormalities, infertility and/or galactorrhea. If drugs and/or PRL adenoma represent the vast majority of causes of hyperprolactinemia, other etiologies and misleading diagnosis of hyperprolactinemia should be searched for. After eliminating a pregnancy, in women of childbearing age, the first step is to interpret the result of hyperprolactinemia, according to the assay technique used. Indeed, the major active form of prolactin is the 23kDA non-glycosylated prolactin. However, some assays interfere with macroprolactinemia, an inactive form of prolactin, including glycosylated prolactin bound to an IgG immunoglobulin. Its presence in the serum is misleading as it may induce increased levels of prolactin, usually below 100 ng/mL. The diagnosis of macroprolactinemia has major issues as pituitary MRI does not need to be performed. Furthermore, neither treatment nor follow-up of patients with macroprolactinemia are necessary. It should be suspected in the presence of normal menstrual cycles. Drugs inducing hyperprolactinemia usually raise prolactin levels below 100 ng/mL. If prolactin level is higher than 250 ng/mL, the main diagnosis is pituitary macro-adenoma. If prolactin ranges between 100 and 250 ng/mL, it is usually related to a micro-adenoma or a necrotic macro-adenoma. A mixed PRL/GH should always be suspected. If prolactin level is below 150 ng/mL, in the presence of a large hypothalamic-pituitary tumor, the major diagnosis is hyperprolactinemia due to pituitary disconnection. Ectopic secretions of prolactin remain very rare. A new etiology of hyperprolactinemia is loss of function mutation of prolactin receptor.
