A positive urine pregnancy test (UPT) with adnexal mass in ectopic pregnancy is not the ultimate diagnosis. The incidence of ectopic pregnancy is about 27 per 1000 pregnancies [1]. On average, about 6-16% will present to an emergency department with first-trimester bleeding and abdominal pain [2]. On presenting with these symptoms with the simultaneous presence of an adnexal mass and an empty uterus, a UPT is of paramount importance to determine whether the symptoms are pregnancy related or not. When the UPT is positive, an ectopic pregnancy is not the only diagnosis as the rare entity of non-gestational ovarian choriocarcinoma (NGOC) should be considered...

INTRODUCTION: Dermoid cysts (DCs) are unusual benign congenital intracranial tumors that typicallyarise in the midline and form as a result of abnormal sequestration of ectodermal cells during neural tubeformation. In all age groups, endoscopic approaches are preferable for the removal of sellar lesions. A 6-year-old girl with recurrent meningitis underwent endoscopic endonasal surgery forsellar DC. CONCLUSION: To the best of our knowledge, we present the first case of a suprasellar DC in a pediatric patient that was removed endoscopically...

Sinus augmentation is a routine procedure performed in patients presenting with severe atrophy of the posterior maxillary alveolar ridge who seek dental implant surgery. Although this strategy is successful in large part, complications such as maxillary sinusitis, antral bleeding, resorption of graft material, infection, failure of implant installation, and oroantral fistula formation are documented on occasion. However, reports of postoperative maxillary cyst (POMC) arising after sinus augmentation are rare...

Intradiploic epidermoid cysts are uncommon in the orbital walls and typically present with chronic headaches. We present the unusual presentation of a 46-year-old man where a long-standing intradiploic mass of the orbital roof led to acute onset of pain and mechanical ptosis. Computed tomography and magnetic resonance imaging revealed an intradiploic cystic mass within the orbital roof. The cystic mass was extirpated and histological examination confirmed the diagnosis of an epidermoid cyst. This case illustrates the potential of long-standing intradiploic epidermoid cysts in producing an acute presentation...

Giardiasis is one of the most common human intestinal diseases worldwide. Several experimental animals have been used to evaluate Giardia infections, with gerbils ( Meriones unguiculatus ) being the most valuable model due to their high susceptibility to Giardia infection, abundant shedding of cysts, and pathophysiological alterations and signs of disease similar to those observed in humans. Here we report cytokine and antibody profiles both during the course of Giardia infection in gerbils and after immunization with a novel oral vaccine comprising a mixture of purified Variant-specific Surface Proteins (VSPs)...

Cystic squamous cell carcinoma (SCC) of the lateral neck is considered metastatic human papilloma virus (HPV)-related oropharyngeal SCC (HPV-OPSCC) until proven otherwise. P16 immunohistochemistry is diffusely positive in those carcinomas and is used as a surrogate marker of active human papillomavirus (HPV) infection. Thyroglossal duct cysts (TDC) are one of the differential diagnoses for cystic neck lesions. SCC arising from TDC is extremely rare. In this study, we report a p16-positive cystic SCC located in the midline neck...

Endoscopic transsphenoidal surgery for pituitary tumors is an increasingly common practice. Little has been reported on the incidence and treatment of postoperative epistaxis in this population. The aim of this study was to analyze the incidence of postoperative epistaxis and formulate a treatment algorithm based on our experience. We performed a case series with chart review. A total of 434 consecutive patients who had endoscopic transsphenoidal pituitary surgery were identified between April 2006 and November 2013...

Scleral cyst is an unusual, rare clinical condition. Most of the cases reported have described the cyst to occur at the limbus, with or without involvement of the cornea. Posterior scleral cysts have seldom been reported in literature. This case report describes a postequatorial scleral cyst that may mimic a choroidal melanoma. Certain clinical features and swept-source optical coherence tomography are useful for elucidating the location of intraocular lesions anatomically, as well as distinguishing their structural characteristics...

Dermoid cysts are benign developmental anomalies that occurred as a result of the sequestration of the skin along the lines of embryonic closure. Those occurring in the cervicofacial region are uncommon, accounting for about 7% of all dermoids and its presence in postauricular region is further exceptionally rare. A healthy 19-year-old Asian boy presented with a unilateral postauricular cyst that had been present since childhood without any symptom. The computed tomography scan revealed an encapsulated tumor with no intracranial extension...

Autosomal-dominant polycystic kidney disease (ADPKD) is a devastating disorder that is characterized by a progressive decline in renal function as a result of the development of fluid-filled cysts. Defective flow-mediated [Ca2+ ]i responses and disrupted [Ca2+ ]i homeostasis have been repeatedly associated with cyst progression in ADPKD. We have previously demonstrated that the transient receptor potential vanilloid type 4 (TRPV4) channel is imperative for flow-mediated [Ca2+ ]i responses in murine distal renal tubule cells...

Giardia duodenalis, Cryptosporidium spp. and Toxoplasma gondii are protozoan parasites that have been highlighted as emerging foodborne pathogens by the Food and Agriculture Organization of the United Nations and the World Health Organization. According to the European Food Safety Authority, 4786 foodborne and waterborne outbreaks were reported in Europe in 2016, of which 0.4% were attributed to parasites including Cryptosporidium, Giardia and Trichinella. Until 2016, no standardized methods were available to detect Giardia, Cryptosporidium and Toxoplasma (oo)cysts in food...

We present a case of aggressive angiomyxoma of the vulva. The patient presented with a persistent, enlarging vulvar mass, initially misdiagnosed as a Bartholin gland cyst. The patient underwent wide local excision, which resulted in total resection of the mass. Final pathology was consistent with aggressive angiomyxoma, a rare soft tissue tumor with a predilection for the female pelvis. Though rare, it is important to consider in the differential diagnosis of a pelvic mass, given the locally aggressive nature of this tumor and propensity for recurrence...

Epidermal inclusion cysts (EICs) are the most common cutaneous cysts, occurring anywhere in the body but infrequently on the breast. It is usually seen in the third and fourth decades of life and very rarely seen in children. They can be either congenital or posttraumatic. Most of the EICs described in children were secondary to trauma. Congenital EIC on the breast is quite a rare entity. Thus, we herein describe two cases of congenital EIC on the breast in two infants of 3 months and 9 months of age, which to the best of our knowledge has not been reported previously...

Branchio-oto-renal (BOR) syndrome is a rare autosomal dominant disorder characterized by branchial cleft fistulae or cysts, preauricular pits, ear malformations, hearing loss, and renal anomalies. Mutations in the human homologue of the Drosophila eyes absent gene ( EYA1 ) are the most common cause of BOR syndrome. PCR and direct sequencing were used to investigate all of the exons and exon-intron boundaries in the EYA1 gene in a patient with BOR syndrome from China. The patient was a child who displayed clinical features of BOR syndrome...

Nasu-Hakola disease (NHD) is a rare autosomal recessive disorder, characterized by progressive presenile dementia and formation of multifocal bone cysts, caused by genetic mutations of either triggering receptor expressed on myeloid cells 2 ( TREM2 ) or TYRO protein tyrosine kinase binding protein ( TYROBP ), alternatively named DNAX-activation protein 12 ( DAP12 ), both of which are expressed on microglia in the brain and form the receptor-adaptor complex that chiefly recognizes anionic lipids. TREM2 transmits the signals involved in microglial survival, proliferation, chemotaxis, and phagocytosis...
