#1
Sasha Mikhael, Wesley Nilsson, Kruti Patel, Sherri Graf
Ectopic breast tissue is a rare condition caused by remnants of the mammary ridges that fail to involute during embryologic development. To date, only 39 cases have been reported in the literature worldwide. Here, we report the 40th case of a 69-year-old G3P2 postmenopausal Caucasian woman who presented with complaint of vulvar swelling. Biopsy of the mass revealed the presence of a benign mammary gland-like adenoma which was completely excised shortly thereafter. Clinical presentation of vulvar breast tissue is highly variable depending on the amount of breast tissue developed and its functionality...

INTRODUCTION: A separate substernal goitre which is not continuous with the main cervical thyroid proves a unique challenge for resection. A trans-cervical approach is preferred but may be hazardous due to the possibility of ectopic thyroid tissue with alternate blood supply. PRESENTATION OF CASE: A 72year old female who had a previous left hemithyroidectomy presents with a symptomatic central substernal thyroid mass. Following radiological work-up, the separate goitre was carefully removed via a trans-cervical approach and avoidance of sternotomy...

The retina offers a unique "window" to study pathophysiological processes of dementia in the brain, as it is an extension of the central nervous system (CNS) and shares prominent similarities with the brain in terms of embryological origin, anatomical features and physiological properties.  The vascular and neuronal structure in the retina can now be visualized easily and non-invasively using retinal imaging techniques, including fundus photography and optical coherence tomography (OCT), and quantified semi-automatically using computer-assisted analysis programs...

BACKGROUND: The prognosis of right colon cancer remains disappointing. Complete mesocolic excision (CME) with central vascular ligation (CVL), based on the same oncological principles of total mesorectal excision, has been speculated to result in a better outcome. To evaluate the oncological adequacy of CME with CVL, we carried out a comparative study with propensity score-matched analysis between two different surgical procedures performed at Italian and Egyptian University cancer centers...

This article focuses on the embryologic development and growth of the temporomandibular joint (TMJ) and touches on the development and growth of surrounding structures. Aberrations in structures surrounding the TMJ can affect its development as well. The normal adult anatomy of the TMJ is described as well as common malformations. The clinical ramifications of a malformed TMJ are also discussed in order to understand future necessary consultants involved in the care of these patients.

Progestin-primed ovarian stimulation (PPOS) protocol has recently been demonstrated to be an novel regimen for preventing premature LH surges during controlled ovarian hyperstimulation (COH) in combination with frozen-thawed embryo transfer (FET). Our prospective controlled study was to explore the effect of human chorionic gonadotropin (hCG) contained in human menopausal gonadotropin (hMG) on the clinical outcomes in normalovulatory women undergoing COH with PPOS. A total of 180 patients were allocated into three groups according to the gonadotropin (Gn) used: group A (human menopausal gonadotropin, hMG-A), group B (hMG-B) or group C (follicle stimulating hormone, FSH)...

The first obvious sign of bilateral symmetry in mammalian and avian embryos is the appearance of the primitive streak in the future posterior region of a radially symmetric disc. The primitive streak marks the midline of the future embryo. The mechanisms responsible for positioning the primitive streak remain largely unknown. Here we combine experimental embryology and mathematical modelling to analyse the role of the TGFβ-related molecules BMP4 and Vg1/GDF1 in positioning the primitive streak. Bmp4 and Vg1 are first expressed throughout the embryo, and then become localised to the future anterior and posterior regions of the embryo, where they will, respectively, inhibit or induce formation of the primitive streak...

We report imaging findings of 3 patients with anterior inferior cerebellar artery (AICA) infarcts who presented with atypical clinical findings of cerebellar strokes. AICA strokes are rare, and diagnosis can be difficult because of the high variability of the posterior circulation vascular anatomy. We describe the embryology and variant anatomy of AICA so that clinicians can understand and recognize the patterns of these infarcts.

INTRODUCTION: The mesodiverticular band (MDB) is an embryologic remnant of the vitelline circulation, which carries the arterial supply to the Meckel diverticulum. In the event of an error of involution, a patent or nonpatent arterial band persists and extends from the mesentery to the apex of the antimesenteric diverticulum. This creates a snare-like opening through which bowel loops may herniate and become obstructed. This report describes 2 rare cases of small bowel occlusion owing to an internal hernia caused by a MDB...

Two cases of thoracic origin of the right renal artery, arising from the level of D11 vertebrae detected on an incidental computed tomography examination are reported. A brief review of embryology is presented. Simultaneous variation of the origin of the right inferior phrenic artery is highlighted as a unique feature of our cases. The importance of this relatively uncommon anomaly in the clinical context is discussed.

In the 1950s, embryology in socialist China underwent a series of changes that adjusted the disciplinary apparatus to suit socialism and the national goal of self-reliance. As the Communist state called on scientists to learn from the Soviets, embryologists' comprehensive view on heredity, which did not contradict Trofim Lysenko (1898-1976)'s doctrines, provided a space for them to advance their discipline. Leading scientists, often trained abroad in the tradition of experimental embryology, rode on the tides of Maoist ideology and repositioned their research...

The cephalic vein arises from the radial end of the dorsal venous arch. It turns around the radial border of the forearm and passes proximally along the arm to the shoulder, where it enters the axillary vein by penetrating the clavipectoral triangle. The cephalic vein is prone to vary at the antecubital fossa, where it forms numerous anastomoses. A male cadaver fixated with a 10% formalin solution was dissected during regular anatomy lessons. It was found that the cephalic vein crossed the upper third of the arm between two fasciculi of the deltoid muscle and reached the shoulder, where it passed above the acromion and crossed the posterior border of the clavicle in order to join the external jugular vein...

The pulmonary veins carry oxygenated blood from the lungs to the heart, but their importance to the radiologist extends far beyond this seemingly straightforward function. The anatomy of the pulmonary veins is variable among patients, with several noteworthy variant and anomalous patterns, including supernumerary pulmonary veins, a common ostium, anomalous pulmonary venous return, and levoatriocardinal veins. Differences in pulmonary vein anatomy and the presence of variant or anomalous anatomy can be of critical importance, especially for preoperative planning of pulmonary and cardiac surgery...

Delineating the lineage of neural cells that captures the progressive steps in their specification is fundamental to understanding brain development, organization, and function. Since the earliest days of embryology, lineage questions have been addressed with methods of increasing specificity, capacity, and resolution. Yet, a full realization of individual cell lineages remains challenging for complex systems. A recent explosion of technical advances in genome-editing and single-cell sequencing has enabled lineage analysis in an unprecedented scale, speed, and depth across different species...

Marcello Malpighi (1628-1694), who is referred to as the father of microscopical anatomy, histology, physiology and embryology was an Italian biologist and physician, well known for his discoveries on microscopical anatomy of kidney, circulating and lymphatic systems. As well as being a brilliant anatomist, Malpighi was also a valued physician so far as to became the personal physician of Pope Innocent XII (1615-1700). On 23 August 1691, one month after his election, the Pope fell to the ground hitting his left hip...

We report a case of sympathetic ophthalmia 1 month following trauma in a 71-year-old immunocompetent female patient of Indian origin. The patient was hospitalized with signs and symptoms of meningism, ataxia, and neurosensory deafness. We explore and provide further clinical evidence in supporting the hypothesis of antigen cross-reactivity derived from tissues with common neural crest embryological background such as the uvea and cells of the labyrinth. The patient was human leukocyte antigen-A2 positive and treatment with oral steroids and cyclosporine has managed to have favorable results and control the inflammation...
