A dermoid is a malformation, a congenital choristoma, in fact an ectopic part of the skin. This malformation can be located on the eyelids (palpebral), on the palpebral or bulbar part of the conjunctive, on the third eyelid or on the cornea, the limbus edge of the eyelid. Ocular dermoids consist of a cornified squamous-stratified epithelium that can be pigmented to various degrees, located on irregular dermis in which there are hair follicles, sweat and fat glands, and, in rare cases, cartilage and bone can also be observed. Corneal dermoids can be classified into three types: limbal or epibulbar dermoid, a dermoid which covers the greater part or the entire cornea, a dermoid that covers the entire front segment of the eye. Coloboma presents a congenital malformation that is characterized by the absence of an eyelid and it can be located on the upper or on the lower lid. This paper presents the case of an English bulldog puppy in which a limbal dermoid and a palpebral coloboma-dermoid were observed at the same time. In this case, superficial keratectomy was selected for the treatment of the limbal dermoid, while the palpebral colobomadermoid was treated using excision with a plastic reconstruction procedure. A microscopic examination of sample tissue of the corneal demoid showed, on the surface, cornified squamous-stratified epithelium lying on the dermis. The dermis was observed to contain hair follicles, as well as sweat and fat glands.

Abstract BACKGROUND AND IMPORTANCE Cavum septum pellucidum (CSP) and cavum vergae (CV) cysts are common incidental findings on imaging studies. However, they may rarely present with symptoms related to the obstruction of the foramen of Monro by the cyst leaflets. There is no consensus regarding the management of symptomatic CSP and CV cysts. We present an original transcavum interforniceal endoscopic fenestration technique. The step-by-step surgical procedure and two illustrative cases are presented. CLINICAL PRESENTATION A 31-yr-old male and a 24-yr-old woman presented with symptomatic CSP and CV cysts. For both patients, neuronavigation was used to plan the procedure. An endoscope was introduced into the cyst through a right frontal burr-hole. After an examination of the endoscopic anatomy, a communication between the cyst and the third ventricle was performed using an endoscopic forceps. In both cases, directly after the fenestration, cerebrospinal fluid (CSF) passed through the communication, and the collapse of the cyst was appreciated. Symptoms were relieved in both patients, and neuropsychological assessment improved. Postoperative imaging showed a reduction in the cyst bulge, and patent foramen of Monro. CONCLUSION Endoscopic fenestration of CSP and CV cysts to the third ventricle through an interforniceal navigated approach is a feasible and efficient surgical procedure. Theoretical advantages include a single tract through noneloquent brain, a perpendicular trajectory to the membrane for fenestration, and a large CSF space beyond the fenestration point.

Abstract Background Conjoined twinning is a rare congenital malformation with an incidence of about 1.5 per 100,000 births. Because no consensus has been reached regarding the dysmorphology, thorough descriptions of conjoined twins as part of teratological collections can be useful to increase knowledge of this congenital malformation. In this case report, we describe a parapagus dicephalus twin from the collection of the Department of Anatomy of the University Medical Center Utrecht in the Netherlands. External anatomical characteristics were assessed through a detailed macroscopic examination and internal characteristics by means of whole-body computed tomography and magnetic resonance imaging (3 Tesla). Case presentation Macroscopic examination showed a Caucasian male parapagus dicephalus tripus tribrachius conjoined twin a type of conjoined twinning in which there are two heads side by side, one rump, and three upper and three lower limbs. In addition, anencephaly was observed in the left twin. Radiological imaging showed a normal central nervous system in the right twin and absence of the calvaria, cerebrum, diencephalon, and mesencephalon in the left twin. There was clear duplication of the vertebral column, rib cage, respiratory system, and gastrointestinal system at least up to and including the first part of the duodenum. The heart consisted of a monoatrium with two separate ventricles. There was a fused liver with a single gallbladder, a single spleen, three kidneys, two bladders, and duplication of the penis. The third upper and lower extremities were articulating with a fused glenoid and acetabulum, respectively. The third foot showed both polydactyly and syndactyly of the toes. Conclusion This case report describes a unique case of a male dicephalus parapagus tripus tribrachus conjoined twin discordant for anencephaly. Radiological imaging proved to be an adequate noninvasive method to provide insights into the internal (dys)morphology of this specific specimen, improving its scientific and educational value. This approach could be generally applied to other teratological specimens, thereby strengthening arguments regarding pathogenetic hypotheses, which may lead to new or improved insights into both normal and abnormal embryonic development.

Instabilities of the craniocervical junction can be of rheumatic, traumatic, or congenital origin. The reported patient has a congenital malformation of the cervical spine, which is frequently observed in patients with Klippel–Feil syndrome. Her posterior arch of the atlas (C1) is hypoplastic and a chronic subluxation of the atlanto-axial joint would be possible. Although most common fusions in Klippel–Feil syndrome patients exist at C2/3, the majority of studies about Klippel–Feil syndrome deal with pediatric or adolescent individuals. Through extreme flexion of her neck, there was a compression of the spinal cord by the odontoid process. This led to a quadriplegia lasting about 10 min. Over the following weeks, all of her symptoms started to diminish. This situation turned out to be the third episode involving temporary neurological disorders in this 60-year-old female’s life.

The weight of internal organs (swimbladder, kidney, liver, spleen) in relation to the body weight was studied in common carp fingerlings divided into three groups on the basis of swimbladder appearance and microscopic examination of the kidney. The fish had been collected from different Hungarian fish farms at the time when swimbladder inflammation (SBI) usually occurs (in July and August). The first group comprised fish with severe signs of SBI and massive renal sphaerosporosis, the second group consisted of fish with milder swimbladder changes and/or kidney infection by a low number of Sphaerospora renicola, while the third group was constituted by infection-free common carp fry. Statistical analysis of swimbladder, kidney, liver and spleen weight in relation to the body weight revealed that in the infected groups the internal organs were substantially enlarged. This suggests that in common carp fry with SBI the swimbladder changes are accompanied by reno-, hepato- and splenomegaly.

Introduction: Trichilemmal cysts (TCs) are common skin lesions that occur in hairy areas. A TC involving a fingertip has not been previously described in the literature. We herein report a case of a TC occupying a fingertip region. Case presentation: A 43-year-old woman presented with a 1.5 × 1.5 cm nodular lesion on the third fingertip. The lesion was completely excised, and histopathological examination revealed a TC. Conclusion: TCs may involve atypical locations, such as fingertips, where there are no hair follicles. After surgical excision, a careful histopathological examination should be performed to differentiate TCs from proliferating pilar tumors.

Hermaphroditism in sea scallops is a relatively rare phenomenon. Observations on two hermaphroditic specimens of Placopecten magellanicus have been documented in the literature. Recent studies on the weathervane scallop, Patinopecten caurinus, in Alaska, have resulted in the discovery of a single hermaphroditic individual from sexual examination through dissection of more than 25,000 individuals over a 3-year study period. The specimen appeared to be a functional hermaphrodite, as both male and female follicules containing well-developed eggs and sperms were clearly evident from microscopic examination. Shell examination showed the animal had formed seven annual rings indicating the animal had spawned more than one season, since weathervane scallops mature after formation of the third annual ring.

Supernumerary teeth and odontomas are obstacles for spontaneous tooth eruption and may result in impaction. The aim of the study is to present a conservative treatment approach for impacted teeth following surgical obstruction removal by reviewing three treatment modalities: surgery only, which involves the surgical removal of the obstruction and the spontaneous eruption; surgery with immediate traction, which includes surgery combined with immediate active orthodontic brace cementation and traction; and surgery with delayed traction, which combines a surgical procedure of obstacle removal and orthodontic brace cementation with follow-up for the spontaneous eruption. The first two modalities require orthodontic traction either by an additional surgical procedure for orthodontic brace cementation, or combined with the surgical obstacle removal. With the third approach, clinical follow-up is performed via connected ligature wire elongation applied during the surgical procedure for the spontaneous emergence of the impacted tooth. Active orthodontic traction is only employed if the tooth fails to erupt. The visual follow-up via wire elongation serves as a reference during the emergence of the impacted teeth and reduces the need for radiographic examination. The surgical-orthodontic approach saves both further surgery and orthodontics (spontaneous eruption) or further surgery (in failure to erupt).

No organ in the body has been the object of a greater number of erroneous descriptions and interpretations of normal and abnormal processes than has the lung and it seems unfortunate that your journal has been guilty of, adding to the welter of misstatements about this organ. simultaneously in the July issue of the AMERICAN JOURNAL OF PATHOLOGY and in PEDIATRICS Dr. H. Edward MacMahon has described a condition under the title "Congenital Alveolar Dysplasia of the Lungs" which he has found in many infants. He believes it is a congenital malformation often incompatible with life, resulting from the failure of alveoli to develop normally. He describes a clinical picture in which the infant is usually normal at birth, becomes progressively dyspneic and cyanotic and often dies of respiratory failure in 36 to 48 hours. Postmortem examination reveals red purple lungs that are of increased size and weight, that contain no visible air and sink in water. In relation to microscopic examination, he states, "There are too few alveoli and there is too much interstitial tissue." "The histologic structure of the lung bears a resemblance to the pattern in a three to four-month-old fetus." "In its simplest form the histologic picture resembles the pulmonary pattern that one finds during the fourth and fifth month of intrauterine life," "This picture of a large lung composed of an excess of primitive but highly vascularized interalveolar mesenchymal tissue, a diminished number of alveoli and many overdistended alveolar ducts constitutes the essential findings in congenital alveolar dysplasia."

Abstract The case of a patient with chronic neutropenia without splenomegaly, but responding favorably to splenectomy is reported. The surgical procedure appeared to be indicated by the following: (1) exclusion of the extrinsic causes of neutropenia; (2) failure of response to the agents commonly employed to stimulate granulopoiesis; (3) demonstration of granulopoiesis in the sternal marrow; (4) increase in the circulating neutrophils following the parenteral administration of epinephrine; (5) the presence of coexisting diabetes with the potential hazard of infection. The implication of the spleen as the main factor in the causation of the neutropenia in this case seems well established, although the specific mechanism is not apparent. There was no evidence of abnormal phagocytosis in the microscopic examination of the spleen.

Two groups of pneumonectomized patients with diagnosis of pulmonary carcimona were successively studied to assess the diagnostic and predictive values of some clotting test in post-operative D. V. T. The incidence of D. V. T. was determined by the 125I fibrinogen method. Simultaneously blood clotting tests including thromboelastography (T.E.G.), P.T.T. platelet count, fibrinogen level, F. D. P. assay, ethanol test were performed both before and after the surgical procedure on the 2d, 4th, a.nd 7th post-operative days. The first group (32 patients) received subcutaneous Heparin beginning on the third post-operative day. The dose (5000 to 10000 u T. I. D.) was adapted according to the results of the T. E. G. in an efford to obtain an isocoagulable state. The second group (45 patients) received 5000 u of heparin subcutaneously (B. I. D.) with the first injection two hours before the surgical procedure: the dose was adapted on the third day according to the T. E. G.The results of this study show: (1) The frequency of blood clotting disturbances is similar in both groups in spite of pre-operative heparinotherapy. (2) The first group presented five D. V. T. and two fatal pulmonary embolisms whereas the second group presented only three D. V. T. (P < 0,1). (3) There is no correlation between a positive scanning of the lower limbs and blood clotting disturbances.In conclusion, clotting disturbances seem to be related to either to surgical procedure or to the carcimona. D. V. T., at early stage, appears to be a local phenomenon which in itself is unable to perturb peripheral blood clotting tests.(Supported in part by a Grant of Inserm: ATP-12-74-33.)
