EYELID & CONJUNCTIVAL TUMORS EYELID & CONJUNCTIVAL TUMORS 5 6 EYELID & CONJUNCTIVAL TUMORS Foreword Dr. Serge Morax I am honored to introduce this Photographic Atlas of palpebral and conjunctival tumors,which is the culmination of the close collaboration between Drs. Olivier Galatoire and Mathieu Zmuda of the A. de Rothschild Ophthalmological Foundation and Dr. Christine Levy-Gabriel of the Curie Institute. The subject is now of unquestionable importance and evidently of great interest to Ophthalmologists, whether they are orbital- palpebral specialists or not. Indeed, errors or delays in the diagnosis of tumor pathologies are relatively common and the consequences can be serious in the case of malignant tumors, especially carcinomas. Swift diagnosis and anatomopathological confirmation will lead to a treatment, discussed in multidisciplinary team meetings, ranging from surgery to radiotherapy. -

View Showed Solid Tissue Fragments Composed of Mature Neural Tissue Comprising Glial Cells and Astrocytes with No Other Germ Cell Layer Component
Saadaat et al. Surgical and Experimental Pathology (2019) 2:24 Surgical and Experimental https://doi.org/10.1186/s42047-019-0049-4 Pathology CASE REPORT Open Access Brain ectopic tissue in sacrococcygeal region of a child, clinically mimicking sacrococcygeal teratoma: a case report Ramin Saadaat1, Jamshid Abdul-Ghafar1*, Ahmed Nasir2, Soma Rahmani2 and Hidayatullah Hamidi2 Abstract Background: Mature brain heterotopic tissue in sacrococcygeal region is a very rare benign congenital abnormality of newborn. To date, only two cases of mature heterotopic brain tissue in the sacrococcygeal region is reported by literature. Heterotopic brain tissue in other areas such as lung, nose, face and retroperitoneal region are also rarely reported. Meanwhile, rather than brain heterotopic tissue in sacrococcygeal region, a case of adrenal gland heterotopic tissue in sacrococcygeal region also has been reported. Case presentation: A 3.5 month-old male baby presented with history of sacrococcygeal mass since birth. Clinical examination of the child was good with no other problem. Sacrococcygeal region revealed an elevated round mass with no discharge. Computed tomography reported a large sacrococcygeal teratoma type-III arising from the sacrococcygeal region extending intra-abdominally to the level of L2 vertebral body. The mass was excised by the impression of sacrococcygeal teratoma (SCT). On gross examination, a gray-white irregular tissue fragment with 5 cm in greatest dimension was examined. Cut sections showed homogenous yellowish white appearance. Histological examination revealed solid fragments composed of mature neural tissue comprising glial cells and astrocytes with no other germ cell layer component. Conclusion: Mature brain heterotopic tissue in sacrococcygeal area is a rare benign disease. -

Abstract Cylindroma of the breast is a very rare lesion which is morphological and immunophenotypically identical to benign dermal cylindroma. We report a breast cylindroma in a previously healthy 62 year old female detected through a national breast screening program. The patient had no significant family or past medical history, and specifically no history of breast or skin diseases. The tumor consisted of well circumscribed islands of epithelial cells surrounded by a dense membrane material, and focally containing hyaline globules. At low power the islands of tumour cells formed a "jig-saw" pattern, which is typical of cylindroma, but was present within normal breast parenchyma and no had direct connection with the overlying skin. -

Hanisch Creighton University, Department of Clinical Anatomy SacrococcygealSacrococcygeal TeratomaTeratoma (SCT)(SCT) •The most common tumor found in newborns. •"Sacro" refers to sacrum and "coccy" refers to coccyx. •Teratoma refers to the type of tissues that make up these growths. They are comprised of chaotically arranged tissues of all types (fat, bone, nerves, muscle, etc…) that are found in an area that they are not normally found. •Sacrococcygeal teratoma (SCT) is rare, occurring in 1 in 35,000 to 40,000 live births. •It is four times more common in females than males. The cause is not known. One theory is it is a failed twinning attempt. Another is it is a growth from an abnormally placed set of germ or stem cells. SacrococcygealSacrococcygeal TeratomaTeratoma (SCT)(SCT) •Those diagnosed in utero carry 50% risk of premature delivery. •Sacrococcygeal teratomas can be quite large. Many are approximately the size of the unborn baby. Tumors greater than 10cm in diameter require cesarean. •Some of the SCTs are cyst-type tumors, meaning they are filled with fluid. Others are solid tumors that may have a significant amount of blood flow through them. The most common type of SCT is a combination of both solid and cystic. •Tumor develops from pluripotential embryonic cells (remnants of primitive streak). Origin of SCT Embryology: •Original germ cells migrating from the yolk sac to the gonad pathway are thought to persist, deviate, differentiate, and mature, typically resting anterior to the future coccyx at Hensen’s node. -
