Primary Hepatic Angioleiomyoma: A Case Report.

BACKGROUND Primary hepatic angioleiomyoma is a rare mesenchymal tumor that is characterized by blood vessels and smooth muscle. Herein, we report an extremely rare case of primary hepatic angioleiomyoma and discuss the clinicopathological features. CASE REPORT A 60-year-old Mongolian man was diagnosed with a hepatic tumor in the second and third segments of screening in 2012. It had been under control by a physician for 10 years. The patient had discomfort and vague pain in the right side of the abdomen since April 2022. Hepatitis virus markers (hepatitis B and hepatitis C) were negative. Plain computed tomography revealed an 80-mm solitary liver lesion in the left lobe with well-defined margins and heterogeneous enhancement. A left hepatectomy was performed in May 2022. The cut surface of the tumor showed a grayish-white, elastic, hard mass with a diameter of 50×80 mm. Histological findings of the tumor revealed that it was clearly demarcated from the surrounding liver tissues with relatively clear boundaries showing thick, muscle-coated blood vessels with perivascular smooth muscle bundles. Immunohistochemical staining showed that the smooth muscle cells were strongly diffuse and positive for smooth muscle actin. CONCLUSIONS Clinically, primary hepatic angioleiomyoma should be distinguished from other types of liver tumors, especially liver cancer. In combination with our long-term observation and other case reports, we recommend general follow-up if the preoperative pathological diagnosis can be confirmed and the patient has no other symptoms.

Being skillful. Wisely navigating an intensely heterogeneous cosmos in Mongolia

This paper proposes to explore how being “skillful” (mergen) plays out and is relied upon in Mongolia within two different contexts, archery and divination, both linked to “cairns” (ovoo) in more than one way. In these contexts, skillful people are expected to embody a virtue that any Mongolian man or woman is supposed to exhibit daily in a less spectacular and consequential manner. As prominent bearers of skillfulness, archers and diviners are indeed relied upon to respond with accuracy to a complex set of potentially clashing variables, and thus to ensure each in their own way the proper and fortunate positioning of people within an intensely heterogeneous cosmos.

Successful medical management of acute mesenteric ischemia due to superior mesenteric and portal vein thrombosis in a 27-year-old man with protein S deficiency: a case report

BackgroundAcute mesenteric ischemia poses a diagnostic challenge due to nonspecific clinical clues and lack of awareness owing to its rarity. Ischemia due to mesenteric venous thrombosis has a good prognosis compared to arterial cause and can be managed conservatively with early diagnosis. The portomesenteric venous system is an unusual site of thrombosis in patients with protein S deficiency, and its thrombosis is an uncommon cause of acute mesenteric ischemia.Case presentationWe present a case of a 27-year-old Mongolian man who presented with acute abdominal pain increasing in severity, and refractory to repeated attempts at treatment with a misdiagnosis of acute peptic ulcer disease. Contrast-enhanced computed tomography of his abdomen detected complete occlusion of the superior mesenteric vein, an extension of acute thrombus into the portal vein, and ischemic mid-jejunal loops. Early diagnosis and immediate anticoagulation with continuous intravenous infusion of unfractionated heparin prevented subsequent consequences. On further workup, our patient was diagnosed with isolated protein S deficiency. We started lifelong thromboprophylaxis with warfarin to prevent recurrence and our patient was asymptomatic on the latest follow-up 5 months after discharge.ConclusionDespite accurate detection of acute mesenteric ischemia by contrast-enhanced computed tomography, high index of suspicion is indispensable for its early diagnosis. Early diagnosis and immediate anticoagulation will prevent subsequent complications and need for surgical intervention. Young patients without known risk factors presenting with venous thrombosis in atypical sites should be investigated for prothrombotic diseases.

Solitary pulmonary mass in a patient with a history of lymphoma: a case report

IntroductionWith the progress made in treatments, the survival rate for patients with malignant lymphoma in the last 30 years has significantly improved. However, the risk of experiencing a second primary malignancy or other disease has increased significantly.Case presentationA 44-year-old Mongolian man with a large mass in his right lower abdomen was admitted to our hospital 15 years previously. The mass was removed, and confirmed via pathological examination to be a malignant B-cell lymphoma in the appendix and distal small bowel. Post-operative chemotherapy with standard cyclophosphamide, hydroxydaunomycin, vincristine (Oncovin®) and prednisolone regimen was given for six cycles. No obvious recurrence was detected over the following 12 years. Subsequently, a mass in the right lung was found on a regular X-ray follow-up; our patient did not report chills, fever or cough. Chest computed tomography and positron emission tomography scans confirmed the mass. A primary lung carcinoma was considered to be the most likely diagnosis. However, after an exploratory thoracotomy and right upper lobectomy was performed a pathological examination of tissue samples demonstrated a lung cryptococcal granuloma, with positive staining for periodic acid Schiff and periodic acid-silver metheramine.ConclusionsCompared to the normal population, second primary malignancy (in particular leukaemia and lung cancer) in patients with malignant lymphoma during their long-term survival has been seen occasionally. However, other diagnoses should also be considered such as pulmonary cryptococcosis. Other than computed-tomography-guided needle biopsy, surgery for some patients is a much more appropriate choice, which could also help attain correct diagnosis and treatment.

Primary central nervous system plasmablastic lymphoma presenting in human immunodeficiency virus-negative but Epstein-Barr virus-positive patient: A case report

We report a 32-year-old Outer Mongolian man, with plasmablastic lymphoma (PBL) primarily occured in the central nervous system and diagnosed by surgical resection. This patient appeared headache and Magnetic resonance imaging (MRI) showed multiple lesions in the right cerebral hemisphere including the right frontal-parietal lobe and right basal ganglia and the left cerebellum, he was diagnosed as lymphoma by stereotactic biopsy in January 2009 in local hospital, and was given radiotherapy 33 times after the biopsy. The patient was admitted to The Military General Hospital of Beijing PLA., Beijing, P.R. China on March 9th, 2011, with chief complaints of right limbs convulsioned suddenly, then fell down and lose of his consciousness, then awoke after 4 to 5 minutes, with symptoms of angulus oris numbness and the right upper limb powerless ten days ago.MRI of the brain revealed a well-defined hyperdense and enhancing mass in the left frontal-parietal lobe, the meninges are closely related, there was extensive peritumoural edema noted with pressure effects, as evident by effacement of the left lateral ventricles and a 0.5 cm shift of the midline to the right side.Surgical resection showed markedly atypical, large singly dispersed or cohesive proliferation of plasmacytoid cells with frequent abnormal mitoses and binucleation, some neoplastic cells were large with round or oval nuclei and showed coarse chromatin and smaller or unapparent nucleoli, some neoplastic cells with prominent nucleoli, apoptosis and necrosis were often presented. Immunohistochemistry staining and gene rearrangement together with other supportive investigation confirmed the diagnosis of primary central nervous system plasmablastic lymphoma. A month later, he was started on chemotherapy with R-CHOP (rituximab, cyclophosphamide, doxorubicin, leurocristime and prednisone) for a week. Other supportive treatment was provided for symptomatic epilepsy. The patient regained muscle strength in both upper limbs and right lower limb and the symptomatic epilepsy was controlled after two weeks. Then the patient was discharged. Follow-up data shows the patient to be alive eleven months after discharge.Virtual SlidesThe virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1649317674697046.

침묵과 부재: 장률 영화 속의 디아스포라

장률 감독은 중국에서는 최초의 조선족 출신 감독이고, 한국에서는 최초의 중국 동포 감독이다. 스스로가 한 명의 디아스포라로서 중국과 한국 두 나라에서, 혹은 두 나라의 사이에서 활동하는 그의 영화 작업은 동아시아에 산재한 디아스포라적인 현상들을 디아스포라적인 시선으로 다룬다는 것으로 요약할 수 있다. 이 글은 <망종>, <경계>, <이리> 등 그가 만든 3개의 작품을 통해 그의 이야기와 스타일을 고찰해 보려는 시도이다. <망종>의 주인공은 중국 대도시 변두리에서 김치 장사를 하는 조선족 최순희이다. 그녀는 산업화로 인한 이산이라는 디아스포라의 보편성과 중국 내 조선족이라는 특수한 디아스포라 상황에 이중으로 속해 있다. <경계>는 몽골의 초원에서 나무를 심는 남자 항가이와 탈북한 모자가 만나서 맺는 관계에 대한 이야기이다. <이리>는 30년 전의 폭발로 사라진 도시 이리에서 부유하는 인물들을 다룬다. 디아스포라적인 시선을 구성하는 장률의 스타일의 첫 번째는 부동하는 공간으로서의 시간이다. 두 번째는 중심과 주변으로서의 외화면과 내화면의 전환이다. 세 번째는 언어의 부재이다. 그의 이런 모든 시도는 동아시아의 정체성에 대한 논의가 활발한 지금 영화 안에서 그것을 탐구하는 하나의 모법으로서 장률의 영화를 주목하게 한다. The first Chinese film maker from Korean ethnicity, Jang Ryul is also the first Korean director from Chinese background. As a diaspora himself, he crosses over two countries, trying to look through diaspora viewpoint at diaspora phenomena widely scattered in Northeast Asia. This paper is written in an effort to closely consider his story and style through 3 films, <Grain in ear>, <Desert Dream>, and <Iri>. The main character in <Grain in ear> is a Korean Chinese woman, Choi Sun Hee, who sells Kimchi in outskirt of a city. <Desert Dream> is the story about the relationship between Hangai, a Mongolian man who plants trees in deserted prairie and North Korean mother and son in defection from North Korea. <Iri> treats a group of characters floating around in Iri, the city that was vanished by the explosion 30 years ago. The first thing of the style of Jang Ryul building the diaspora viewpoint is time, crossing the floating space. The second one is the inversion of on-screen space and off-screen space or center and periphery. The third one is the absence of language. Given the fact that discourses about the identity of East Asia flourish these days, his movies, as the fruit of consistent attempt to search for East Asian identity within the filmmaking process, deserve more attentions.
