8 mm. The pituitary stalk was thickened without deviation, and there was an elevation of the optimal crossing. MK-8719 The lesion grew bilaterally toward the cavernous sinuses, and the parasternal dural caudal sign was visible. The patient presented with repeatedly worsening and prolonged headaches three times even though the hypopituitarism had fully resolved after glucocorticoid treatment during this course.
This rare headache regression suggests that patients with chronic headaches should also be alerted to the possibility of LYH.

Multiple endocrine neoplasia type 1 (MEN1) is a rare hereditary tumor syndrome inherited in an autosomal dominant manner and presents mostly as parathyroid, endocrine pancreas (such as gastrinoma) and anterior pituitary tumors. At present, papillary thyroid carcinoma (PTC) and nodular goiter are not regarded as components of MEN1.
A 35-year-old woman presented with MEN1 accompanied by coinstantaneous PTC and nodular goiter. The pathological diagnosis was PTC with cervical lymph node metastasis, nodular goiter, parathyroid cyst and adenomatoid hyperplasia. Genetic testing was performed and a
gene mutation was detected. The patient underwent unilateral lobectomy of the thyroid gland and surgical removal of the parathyroid tumors. At 18 mo of follow-up, ultrasonic examination of the neck showed no abnormality. Serum calcium and parathyroid hormone levels were normal. No new MEN1-associated tumors were detected.
The role of inactivating mutations of
gene in tumorigenesis of PTC and/or nodular goiter remains to be determined by more case reports and further research.

Othello syndrome (OS) is characterized by delusional beliefs concerning the infidelity of a spouse or sexual partner, which may lead to extreme behaviors. Impulse control disorders refer to behaviors involving repetitive, excessive, and compulsive activities driven by an intense desire. Both OS and impulse control disorders in Parkinson's disease (PD) may be side effects of dopamine agonists. At present, there are only a few case reports and studies related to PD with concomitant OS and impulse control disorders.
We describe a 70-year-old male patient with PD, OS, and impulse control disorders, who presented with a six-month history of the delusional belief that his wife was having an affair with someone. He began to show an obvious increase in libido presenting as frequent masturbation. He had been diagnosed with PD ten years earlier and had no past psychiatric history. In his fourth year of PD, he engaged in binge eating, which lasted approximately one year. Both OS and hypersexuality were alleviated substantially after a reduction of his pramipexole dosage and a prescription of quetiapine.
Given its potential for severe consequences, OS should be identified early, especially in patients undergoing treatment with dopamine agonists.

Sjogren's syndrome (SS), which affect salivary gland function, is an autoimmune disease. SS may involve extraglandular organs. Approximately 10 to 20 percent of SS patients have clinically significant lung disease, but presentation of pulmonary amylodosis is extremly rare. The incidence of benign monoclonal gammopathy in SS patients is high, but multiple myeloma is rare. No case involving the simultaneous occurrence of two rare diseases, pulmonary amyloidosis and multiple myeloma, in the same patient with SS has been reported so far.
A 41-year-old male patient was referred to our hematology department due to incidentally detected gastric plasmacytoma. He had been diagnosed with SS four years earlier. Multiple miliary nodules, ground glass opacity in both lung fields, and enlargement of both inguinal lymph nodes was observed on chest and abdomen computer tomography. Based on the pathological findings of lung and lymph node biopsied specimens, the patient was diagnosed with pulmonary amyloidosis and multiple myeloma. Pulmonary amyloidosis and multiple myeloma associated with SS has rarely been reported.
This is an extremely rare case of simultaneous pulmonary amyloidosis and multiple myeloma in the same patient with SS.

Meningiomas are benign tumors that originate from the meningothelial arachnoid cells, but they rarely develop extracranially. There is no specific surgical guideline for resecting them in the maxillary sinus, and little is known about their biological behavior and operative management.
We present a 54-year-old female patient referred to our department with a primary extracranial meningioma that presented as buccal swelling associated with headache. On clinical examination the mass was non-tender, fixed, sessile and non-pulsatile situating in the right maxillary sinus. Computed tomography scan showed a well-defined mass of 7 cm × 6 cm × 6 cm compressing the surrounding structures. Magnetic resonance imaging revealed a well circumscribed heterogenous lesion with necrotic center and relatively hypointense on T2-weighted imaging. link2 Imaging studies revealed no evidence of intracranial extension and metastatic nests. Biopsy showed grade I primary extracranial with low mitotic activity. Total maxillectomy with excsinuses may be successfully managed by surgical treatment without evident post-surgery complications.
Intraductal papillary neoplasm of the bile duct (IPNB) rarely recurs in a multicentric manner. We encountered a patient with multiple recurrences of the gastric subtype of IPNB one year after spontaneous detachment of the primary tumor during peroral cholangioscopy (POCS).
A 68-year-old woman on maintenance hemodialysis because of lupus nephritis had several cardiovascular diseases and a pancreatic intraductal papillary mucinous neoplasm (IPMN). She was referred to our department for dilation of the common bile duct (CBD) and a tumor in the lumen, detected using ultrasonography. She had no complaints, and blood tests of hepatobiliary enzymes were normal. Magnetic resonance cholangiopancreatography (MRCP) showed a papillary tumor in the CBD with a filling defect detected using endoscopic retrograde cholangiography (ERC). Intraductal ultrasonography revealed a papillary tumor and stalk at the CBD. During POCS, the tumor spontaneously detached with its stalk into the CBD. Pathology showed low-intermediate nuclear atypia of the gastric subtype of IPNB. link3 After 1 year, follow-up MRCP showed multiple tumors distributed from the left hepatic duct to the CBD. ERC and POCS showed multicentric tumors. She was alive without hepatobiliary symptoms at least two years after initial diagnosis of IPNB.
The patient experienced gastric subtype of IPNB without curative resection. Observation may be reasonable for patients with this subtype.

Ankylosing spondylitis (AS) is strongly associated with the human leukocyte antigen (HLA) B27 haplotype. In regions where conventional polymerase chain reaction for HLA typing is available for antigens such as HLA B27 or HLA B51, it is common to perform the HLA B27 test for evaluation of AS. While HLA B27-associated clustered occurrences of AS have been reported in families, we report the first case series of HLA B51-related occurrences of AS in a family.
A father and his daughters were diagnosed with AS and did not have the HLA B27 haplotype. Although they were positive for HLA B51, they exhibited no signs of Behçet's disease (BD). Of the five daughters, one had AS, and three, including the daughter with AS, were positive for HLA B51. The two daughters with the HLA B51 haplotype (excluding the daughter with AS) exhibited bilateral grade 1 sacroiliitis, whereas the daughters without the HLA B51 haplotype did not have sacroiliitis. Thus, this Korean family exhibited a strong association with the HLA B51 haplotype and clinical sacroiliitis, irrespective of the symptoms of BD.
It is advisable to check for HLA B51 positivity in patients with AS/spondyloarthropathy who test negative for HLA B27.

Intravascular fasciitis (IVF) is a rare nodular fasciitis that often involves the layers and lumens of blood vessels; therefore, it is easily misdiagnosed as a malignant tumor with invasion into blood vessels.
A 13-year-old boy was admitted due to a mass on the left side of his neck. Duplex ultrasonography revealed a circular solid hypoechoic mass in the external jugular vein, and magnetic resonance imaging revealed an enhanced longitudinal mass-like lesion in the left supraclavicular fossa. Surgical treatment was arranged and completed, histopathological analysis showed a large amount of spindle cell proliferation, and immunohistochemistry showed that the spindle cells were positive for the expression of vimentin, caldesmon, and smooth muscle actin and negative for the expression of S-100 protein, desmin, CD34, and c-kit; Ki-67 staining revealed a low proliferative index (5%-10%), which confirmed the differentiation characteristics of myofibroblasts. Fluorescence in situ hybridization detected the rearrangement of USP6. IVF was subsequently diagnosed.
IVF is characterized by intraluminal, intramural and extramural involvement of small to large arteries or veins. Unless the doctor has a deep understanding of the disease or suspects that there is an initial indicator, IVF may be confused with other intravascular malignancies, leading to unnecessary radical surgery. Imaging examination combined with histopathological examination can improve the diagnostic accuracy of this disease.

Longstanding intestinal inflammation increases the risk of colorectal neoplasia in patients with inflammatory bowel disease (IBD). Accurately predicting the risk of colorectal neoplasia in the early stage is still challenging. Therefore, identifying visible warning markers of colorectal neoplasia in IBD patients is the focus of the current research. Post-inflammatory polyps (PIPs) are visible markers of severe inflammation under endoscopy. To date, there is controversy regarding the necessity of strengthened surveillance strategies for IBD patients with PIPs.
To determine whether IBD patients with PIPs carryan increased risk of colorectal neoplasia.
Researchers searched the following databases up to July 31, 2021 MEDLINE (PubMed), MEDLINE (Ovid), EMBASE, Cochrane Library, China National Knowledge Infrastructure, Wan-Fang Data, China Science and Technology Journal Database and Chinese BioMedical Literature Database. Cohort and case-control studies that compared the risk of colorectal neoplasia between IBD patients with or without PIPs and published in English or Chinese were included.
