One of the most uncommon stress lesions of the shoulder in adolescents is an avulsion of the lesser tuberosity of the proximal humerus. To our knowledge, only 2 other cases of lesser tuberosity ...

Gastric adenomyoma in children is a rare benign tumor composed of a mixture of duct-like epithelial structures with smooth muscle bundles. It has been considered as a subtype of ectopic pancreas because the epithelial component resembles that in pancreatic ducts. However, it is now recognized as an independent pathologic lesion. ...

Hiccup is the sudden onset of erratic diaphragmatic and intercostal muscle contraction and immediately followed by laryngeal closure. The abrupt air rush into lungs elicits a "hic" sound. Hiccup is usually a self-limited disorder; however, when it is prolonged beyond 48 hours, it is considered persistent whereas episodes longer than ...

Hypochondroplasia (HCH) is the mildest phenotype among fibroblast growth factor receptor 3 (FGFR3)-associated skeletal dysplasias. Affected individuals usually presents with mild short stature in preschool age. It was uncommon that a diagnosis of HCH is made in young affected children. Recently, however, prenatal ultrasound (US) has increased likelihood of detecting ...

A 30-year-old female presented with unilateral labial enlargement. The clinical impression was that of a benign cyst. The microscopic features were that of angiomyofibroblastoma showing hyper and hypocellular areas containing spindle and plump stromal cells admixed with blood vessels. This tumour is benign with extremely low rate of recurrence. Surgery ...

The fine macroscopic observation of a young adult female skeleton recovered from a Roman graveyard in Romania revealed distinctive flattening of the vertebra related to a right-sided aorta. Associated bone anomalies may be related to a Kartagener syndrome. This case highlights the fact that visceral anomalies may be diagnosed even ...

Thrombus formation on disrupted atherosclerotic lesion is a key mechanism of cardiovascular events. Podoplanin (Aggrus), expressed on the surface of several tumor cells, is an endogenous ligand for C-type lectin-like receptor 2 (CLEC-2), and is involved in tumor cell-induced platelet aggregation and its malignant potency. Podoplanin, which is also expressed ...

Benign Masseteric Hypertrophy is a relatively uncommon condition that can occur unilaterally or bilaterally. Pain may be a symptom, but most frequently a clinician is consulted for cosmetic reasons. In some cases prominent Exostoses at the angle of the mandible are noted. Although it is tempting to point to Malocclusion, ...

This case report describes a 10-year-old horse that developed multiple dermal papules over the right masseter area following removal of a tick from the same site 3 months earlier. Histological examination of a biopsy from a papule was suggestive of either a T-cell-rich B-cell lymphoma or cutaneous lymphoid hyperplasia, a form ...

To the Editor: Tick-borne rickettsioses are zoonoses caused by intracellular bacteria belonging to the spotted fever group rickettsiae (1). The main clinical signs are high fever, maculopapular rash, and an inoculation eschar at the site of the tick bite (corresponding to the portal of entry of rickettsiae into the host). ...

Reasons for performing study: Although experimental studies have demonstrated differences in performance between methods for handsewn jejunojejunostomy in horses, information on clinical results after different methods of anastomosis are rare. Hypothesis: A continuous Lembert pattern wrapped in a carboxymethylcellulose and hyaluronate membrane would perform better than an interrupted Lembert pattern ...

Dermatophilosis was diagnosed in 14 (13.6%) of the studied camels. Grossly, patchy thickening of the skin with dark brown scabs or crusts were observed on the rump, flanks, abdomen, ...

This is the first report of the isolation of Actinomyces denticolens, an opportunistic pathogen, from a draining submandibular lymph node abscess in a horse in Ontario. Due to the similarity of the clinical signs with strangles, this pathogen should be included in the differential diagnosis of submandibular lymphadenopathy in the ...

Neuroendocrine tumors of the uterine cervix (UC) are rare, and atypical carcinoid (AC) combined with adenocarcinoma of the uterine cervix (ACAUC) is particularly rare. Only the histopathology has been investigated in the English literature. A 49-year-old female with a polypoid lesion of the UC visited Yamanashi Prefectural Central Hospital. Scraping ...

The present study aimed to evaluate a novel fluorescence in situ hybridization (FISH) assay for detecting the high-risk human papillomavirus (HR-HPV) DNA and signal pattern in cervical cytology specimens and for identifying cervical intraepithelial neoplasia (CIN) lesions. One hundred and ninety-six liquid-based cytology specimens with CIN were recruited. The signal ...

Ticks transmit a variety of infectious diseases. Diagnosis requires verification of a tick's presence. Here, we describe a 61-year-old woman bitten by an eight-legged nymphal Amblyomma testudinarium. We re-emphasize the usefulness of dermoscopy for identifying signs of the bite and determining the species of the biting tick.

Plunging ranulas are rare cystic masses in the neck that are mucous retention pseudocysts from an obstructed sublingual gland. They "plunge" by extending inferiorly beyond the free edge of the mylohyoid muscle, or through a dehiscence of the muscle itself, to enter the submandibular space. Imaging demonstrates a simple cystic ...

Spindle cell hemangioendothelioma (SCH) was originally described by Weiss and Enzinger (1986) as a low-grade angiosarcoma resembling both cavernous hemangioma and Kaposi's sarcoma. Recent studies suggest that SCH is a benign neoplasm or reactive lesion accompanying a congenital or acquired vascular malformation. Most SCHs present as one or more nodules ...

Atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H) category was added to the 2001 Bethesda System. ASC-H accounts for a small percentage (0.2-0.6%) of abnormal Pap smears and includes heterogenous group of lesions. There are more high-grade cervical lesions (30-50%) in ASC-H than ASC-US (10-15%). An accurate Pap ...

The objective of this study is to detect the infection of human papillomavirus (HPV) and the expression of p16(INK4a) in cervical lesions and to investigate the interaction between hrHPV and p16(INK4a) for cervical lesions and its diagnostic efficiency. hrHPV-DNA was detected by the hybrid capture II (HC-II) system. Immunochemical method ...
