Baofeng Xu, Yandong Zhang, Jinlu Yu
In patients without systemic manifestations of tuberculosis, isolated brainstem tuberculous abscesses are infrequently observed. The present study reports a rare case of two cystic tuberculous abscesses involving the dorsal aspect of the medulla oblongata in an otherwise healthy 14-year-old Chinese girl, whose primary complaint was respiratory distress. These lesions were successfully treated using a microsurgical excision approach and anti-tuberculosis therapy. Although rare, tuberculous abscesses should be considered in the differential diagnosis of isolated cystic brainstem lesions...

The clinical and histopathological distinction between keratoacanthoma (KA) and squamous cell carcinoma (SCC) is essential, but frequently difficult to make. The utility of CK17 and Ki-67 expression in distinguishing between KA and SCC was investigated. Immunohistochemical staining patterns for CK17 and Ki-67 were evaluated in 24 KA and 27 SCC cases. The pattern of staining was evaluated as central, peripheral or diffuse, according to the basal/peripheral and suprabasal/central cell staining of tumor lobules...

Neutropenia in the setting of acute hematological malignancies may impact disease prognosis, thus affecting therapy dose intensity. This is often due to chemotherapy-induced aplasia as well as to the disease itself. However, chronic neutropenia deserves further investigation, as the management of reversible concomitant causes may avoid treatment delay. The present study describes a case of an acute promyelocytic leukemia patient with chronic severe neutropenia of multifactorial origin, including acute leukemia itself, chemotherapy, autoimmune activation with anti-platelets and anti-neutrophil antibodies positivity, and the rare association of large granular lymphocyte (LGL) expansion...

Heart failure with preserved ejection fraction is often preceded by diastolic dysfunction (DD). Of several published DD criteria, it is unclear which, if any, are applicable to data obtained in epidemiologic cohorts. We evaluated the prevalence of DD using previously published definitions in a population-based study, the Coronary Artery Risk Development in Young Adults (CARDIA) Study, using data gathered in 2010-2011. Echocardiography was performed on 3,474 individuals (mean age = 50.2 years) at the CARDIA year 25 examination...

Heart failure with preserved ejection fraction (HFpEF) is common, recalcitrant to treatment, and associated with poor outcomes. Diastolic dysfunction (DD) is an independent predictor of HFpEF risk, associated clinical manifestations, and long-term outcomes. However, the usefulness of diastolic function assessment is limited by the heterogeneity in the existing definitions of DD. In this issue of the Journal, Rasmussen-Torvik et al. (Am J Epidemiol. 2017;000(00):000-000) have highlighted this problem by evaluating the prevalence and concordance of 4 established definitions of DD in the Coronary Artery Risk Development in Young Adults (CARDIA) cohort...

Myelolipoma is a kind of rare benign tumour composed of mature adipocytes and hemopoietic elements, and is most often found in the adrenal glands. Primary mediastinal myelolipoma (PMM) more rarely happens and has no definite symptoms, and mediastinal masses are usually found in chest examination. The patients normally receive a surgical resection and have a favorable prognosis after postoperative pathological diagnosis. Here, we present the case of PMM, which was resected via video-assisted thoracic surgery (VATS), and investigate recent correlative literatures to summarize its etiology, histopathology, differential diagnosis and therapeutic method...

BACKGROUND: Pulmonary inflammatory myofibroblastic tumor (IMT) has been considered as a synonym for inflammatory pseudotumor (IPT) for a long time. Recent studies have indicated that IMT and IgG4-related IPT are distinct diseases. However, no consensus criteria have been recommended. Here we propose a set of criteria for the differential diagnosis. METHODS: Twenty-six archived IMT and IgG4-related IPT samples were examined for histological characteristics and the expression of IgG, IgG4, SMA and ALK-1...

BACKGROUND: Temporomandibular disorder (TMD) incidences are believed to be related to parafunctional behaviors like teeth clenching. OBJECTIVES: This pilot study aimed to (i) develop an automated clench-detection algorithm, and (ii) apply the algorithm to test for differences in nocturnal clenching in women with and without TMD. METHODS: Subjects gave informed consent to participate. Adult women were categorized using Diagnostic Criteria for TMD according to presence/absence (+/-) of both TM joint disc placement (DD) and chronic pain (P) into two groups (+DD+P, -DD-P) with 12 subjects each...

An 8-year-old female Boxer was examined for acute onset of seizures. On magnetic resonance imaging (MRI), an intra-axial mass with imaging features consistent with glioma was observed in the right cerebral hemisphere. A defect in the temporal bone adjacent to the mass was observed. Postmortem computed tomography (CT) confirmed temporal bone osteolysis and necropsy demonstrated a glioblastoma with associated calvarial erosion. Although occasionally described in human medicine, to our knowledge, this is the first description of a brain glioma causing calvarial erosion in a dog...

BACKGROUND: Quadratus femoris tear is an uncommon injury that usually cause hip pain, it incidence is unknown. The patient can suffer of posterior gluteal pain or groin pain or both, which makes accurate diagnosis difficult, because the differential diagnosis of hip pain is broad. CLINICAL CASE: A 65 years old male, with gluteal and groin pain presented during tennis; evaluated by neurologist with lumbosacral magnetic resonance imaging (MRI) (normal) and referred to physical therapy, a pelvic MRI was required, finding an unsuspected quadratus femoris tear...

Asymptomatic heterotopic pancreas (HP) is benign and can be monitored long term without further intervention. Heterotopic pancreas is sometimes surgically resected because it can be difficult to distinguish HP from neoplastic submucosal masses such as gastrointestinal stromal tumors. Although it is not very common, HP should be considered in the differential diagnosis when diagnosing extramucosal gastric masses to avoid unnecessary intervention. We review gastric HP with pathologic correlation to help with diagnosing HP on computed tomography...

PURPOSE: Left atrium (LA) enlargement on echocardiography may be an indicator of diastolic dysfunction (DD). It is not well known if computed tomography pulmonary angiography (CTPA) can detect DD. METHODS: A total of 127 patients who underwent both CTPA and echo within 48 hours were analyzed retrospectively. Left atrium diameters from CTPA were correlated with echo and evaluated against degrees of DD. Computed tomography pulmonary angiography pulmonary artery (PA)/aorta ratio was analyzed as a tool to detect pulmonary hypertension...

Splenic inflammatory pseudotumor (IPT) is an uncommon lesion with an inflammatory morphologic aspect that often poses a diagnostic challenge. The etiology of IPT can be infectious, autoimmune, reactive, or neoplastic. Splenic Epstein-Barr virus (EBV)-associated IPTs form a subset of splenic IPTs in which there is a spindle cell component infected by EBV. The best characterized and most frequent subgroup of splenic EBV-associated IPT is IPT-like follicular dendritic cell tumor. This review also focusses on EBV-associated splenic IPTs without follicular dendritic cell marker expression...

Nonsystemic vasculitic neuropathy (NSVN) is an under-recognized single-organ vasculitis of peripheral nerves that can only be diagnosed with a nerve biopsy. A Peripheral Nerve Society guideline group published consensus recommendations on the classification, diagnosis and treatment of NSVN in 2010, and new diagnostic criteria for vasculitic neuropathy were developed by the Brighton Collaboration in 2015. In this Review, we provide an update on the classification, diagnosis and treatment of NSVN. NSVN subtypes include Wartenberg migratory sensory neuropathy and postsurgical inflammatory neuropathy...

Oesophageal sarcomas are very rare while various histological types have occasionally been reported. Malignant Peripheral Nerve Sheath Tumour (MPNST) of the oesophagus is an exceedingly rare type of oesophageal sarcoma with only thirteen cases previously reported in the world literature. However, it should be included in the differential diagnosis of oesophageal neoplasias. Due to the small number of reported cases, the information about the biological behaviour of this entity is still insufficient. While MPNST is generally considered an aggressive type of tumour with high recurrence rates after surgical treatment and poor prognosis, previous reports of cases with oesophageal localization have recorded satisfactory outcomes overall even with less aggressive therapeutic approaches, although a long-term follow-up is lacking...

REVIEW
D S Chabot-Richards, K Foucar
Numerous non-neoplastic and neoplastic conditions manifest with distinctive features in blood. Although automated complete blood count (CBC) data are essential, CBC information alone is insufficient for diagnosis. Consequently, morphologic review of blood smears is still relevant in the era of sophisticated automated analyzer systems. Pathologist interpretation of the peripheral blood smear, in conjunction with CBC and clinical information, can provide rapid diagnostic information and guide cost-effective targeted laboratory testing...

A 52-year-old woman was admitted with a large intraabdominal mass. (123)I- metaiodobenzylguanidine ((123)I-MIBG) scintigraphy revealed considerable (123)I-MIBG accumulation by the mass that was compatible with a diagnosis of paraganglioma. However, a spindle cell tumor that was identified using endoscopic ultrasound-guided fine needle aspiration before surgery was positive for CD117. The surgically resected mass was confirmed as a gastrointestinal stromal tumor (GIST). Although the mechanism of (123)I-MIBG uptake by GIST has not been elucidated, GIST should be included in the differential diagnosis of intra-abdominal tumor with (123)I-MIBG uptake...
