A Rare Case of Primary Apocrine Adenocarcinoma Arising Within a Mature Cystic Teratoma of the Ovary, Metastatic to a Supraclavicular Lymph Node.

Mature cystic teratoma of the ovary is one of the most common benign tumours among reproductive aged women. Malignant transformation of a mature cystic teratoma is uncommon and metastatic malignancy is extremely rare. We report the first known case of an apocrine adenocarcinoma arising within an ovarian mature cystic teratoma which on follow-up six months later was found to be metastatic to the left supraclavicular lymph node. There are usually no pre-operative findings to raise the suspicion of malignancy ...

Mature Cystic Teratoma With an Element of Hepatocellular Carcinoma in Anterior Mediastinum: Magnetic Resonance-Pathologic Correlation.

De Novo Tumors of Teratoma: Ganglioneuroma Arising From a Mature Cystic Teratoma of the Ovary.

Mature teratomas are the most common ovarian neoplasms, accounting for 40% to 50% of ovarian tumors, and are histologically defined by the presence of multiple lineages of mature differentiated cells derived from one or more of the 3 embryonic germ layers; ectoderm, mesoderm, and endoderm. Neuroectodermal and neural crest differentiation can be observed in mature teratomas, but it is uncommon to find secondary tumors that arise from the neural crest lineage. Herein we report the uncommon finding of a gangli...

Metastatic Endocervical Adenocarcinoma in a Mature Cystic Teratoma: A Case of a Tumor-to-Tumor Metastasis.

Tumor-to-tumor metastasis is a rare phenomenon defined as a to metastasis in a histologically distinct tumor. We report an unusual case of a 51-yr-old woman who presented with a cervical, bleeding lesion diagnosed as a poorly differentiated adenocarcinoma, HPV18+. Imaging studies revealed an unresectable cervical carcinoma with an associated left ovarian multicystic teratoma. A suspicious solid nodule within the teratoma was also reported. Bilateral salpingo-oophorectomy was performed before the cervical tu...

Carcinoid Arising From the Teratomatous Bronchial Mucosa in a Mature Cystic Teratoma of the Ovary: A Case Report.

Primary ovarian carcinoids are relatively uncommon, either pure (monodermal teratomas) or in association with mature cystic teratomas. Here we reported a unique case of carcinoid arising from the teratomatous bronchial mucosa in an ovarian mature cystic teratoma in a 22-year-old woman. This tumor showed compact trabecular and nested growth pattern with salt-and-pepper chromatin pattern. Mitotic figures were identified (6/10 high power fields) and focal necrosis was present. Immunohistochemically the tumor c...

A review of primary malignant melanoma arising in an ovarian cystic teratoma.

Primary malignant melanoma arising in an ovarian cystic teratoma is exceedingly rare event with an estimated incidence of 0.2-0.8%. So far, there have been approximately only 47 relevant reports. We report a case of primary malignant melanoma of the ovary arising in a cystic teratoma here. Moreover, we review systematically the disease from the following aspects, that origin, clinical characteristics, accessory examination, pathological features, diagnosis, differential diagnosis, treatment, prognosis.

Bilateral ovarian angiosarcoma arising from the mature cystic teratomas - A case report and review of the literature.

Ovarian teratomas undergo the malignant transformation in 0.2-2% of cases. The behavior of malignancies in mature cystic teratomas (MCT) is determined by their phenotype and not their derivation from germ cells. We can recognize pure angiosarcomas or as a part of other tumors like malignant mixed Mullerian tumors and adenosarcomas.

A Case of Adult Mature Teratoma Located in Retroperitoneum.

A 35-year-old man wasreferred to our hospital for treatment of a right adrenal tumor detected by ultrasonography during a physical check-up. Contrast-enhanced abdominal computed tomography revealed a poorly enhanced 74 mm tumor situated adjacent to the upper pole of the right kidney. The tumor consisted of fat with peripheral calcification. Magnetic resonance imaging also revealed a right retroperitoneal tumor with fatty contents and well-circumscribed capsule. The endocrine examination revealed the tumor a...

Ganglioneuroblastoma Arising in an Ovarian Dermoid Cyst: First Report in the Literature.

The development of a somatic neoplasm within an ovarian dermoid cyst (mature cystic teratoma) is a rare, but well described, phenomenon which occurs in approximately 1% of all cases. Any of the tissue components of a dermoid cyst has the potential to undergo neoplastic transformation with carcinoid tumors and squamous cell carcinomas being among the most common neoplasms. We report a case of a ganglioneuroblastoma arising within an ovarian dermoid cyst, an association which, as far as we are aware, has not ...

Retroperitoneal teratoma simulating giant adrenal myelolipoma: a diagnostic puzzle.

Teratoma is a germ-cell tumour that is common in para-axial regions. Retroperitoneal teratoma is rare and comprise only about 1% of all teratomas. We present a 21-year-old female who presented with a lump in the abdomen. After radiological investigations, she was diagnosed as case of adrenal myelolipoma which on excision turned out histologically to be retroperitoneal teratoma. Our case highlights the limitation of radiological investigations in preoperative diagnosis of teratoma.

Mature Ovarian Teratoma After Treatment for Unilateral Retinoblastoma With Nonmutated RB1.

IDENTIFICATION OF CAUSES OF EARLY PREGNANCY LOSSES ACCORDING TO HYSTOMORPHOLOGIC FEATURES.

Retrospective analysis of the early spontaneous abortions has been conducted (486 cases). Histomorphologic analysis of the curettage material contents erveledinvolutive-regressive developmental chsnges in 108 (22,28%) cases, in 370 cases (77.78%) pathologic changes, like inflammatory changes of deciduas and chorionic villis in 302 cases (80.2%), pathologic prematurity of chorionic vili in 48 cases (12.6%), hydatidiform mole in 28 cases (7.4%). As most cases of pregnancy loss has been reported at 7-9 weeks /...

Gnathic Osteosarcoma: Clinical, Radiologic, and Pathologic Review of Bone Beard Tumor.

Adult Brainstem Gliomas With H3K27M Mutation: Radiology, Pathology, and Prognosis.

Adult brainstem gliomas are difficult to classify based on radiologic and histologic features. A K27M mutation in histone 3 has been described to identify high-grade midline gliomas associated with a particularly unfavorable prognosis. While initially considered a pediatric entity, it is now known that H3K27M-mutant brainstem gliomas occur in all age groups, but they are less well understood in adults. We studied clinical, radiologic, and pathologic features of 25 brainstem gliomas diagnosed at our institut...

Congenital Cystic Lung Lesions: Evolution From In-utero Detection to Pathology Diagnosis-A Multidisciplinary Approach.

Congenital cystic lung lesions are a group of rare pathologies that are usually diagnosed in the prenatal period. The majority of these lesions are diagnosed at pathology examination as congenital pulmonary airway malformations (CPAM) and bronchopulmonary sequestration (BPS). These lesions are typically managed by surgical intervention within the first year of life and have an excellent prognosis. We examined the evolution of imaging appearances from prenatal diagnosis to postnatal work-up of these lesions ...

Uterine cervical adenocarcinoma associated with lobular endocervical glandular hyperplasia: Radiologic-pathologic correlation.

We aimed to identify the radiologic features of uterine cervical adenocarcinoma associated with lobular endocervical glandular hyperplasia (LEGH).

Pleuroparenchymal fibroelastosis in heterogeneous clinical conditions: Clinicopathologic analysis of seven cases.

Pleuroparenchymal fibroelastosis (PPFE) is classified as a rare idiopathic interstitial pneumonia, and its clinicopathologic features remain unclear. We sought to investigate the clinical, radiologic, and pathologic features of patients with histologically proven PPFE.

Orbital emphysema: radiologic and ophthalmologic findings.

Orbital emphysema, or the presence of air in orbital tissues, is normally associated with an injury although it can arise when a Valsalva maneuver causes an increase in upper airway pressure. This potential complication of an orbital wall fracture, usually in the ethmoid bone, occurs in 50% of such cases. On fracture, air passes from the nasal fossa, sinuses, or subcutaneous tissue. The condition is benign and transient in most cases, and loss of vision is rare. No protocol for treating orbital emphysema wi...

IL-1α promotes pathogenic immature myeloid cells and IL-1β favors protective mature myeloid cells during acute lung infection.

Bacterial pneumonia is a common risk factor for acute lung injury and sepsis-mediated death, but the mechanisms underlying the overt inflammation and accompanying pathology are unclear. Infiltration of immature myeloid cells (IMC) and necrotizing inflammation mediate severe pathology and death during pulmonary infection with Francisella tularensis. However, eliciting mature myeloid cells provides protection. Yet, the host factors responsible for this pathologic IMC response are unknown. Here, we report that...

Hepatic Portocholecystostomy: 97 Cases From a Single Institution.

About 20% of cases of biliary atresia (BA) do not involve the gallbladder, the cystic duct and the common bile duct. In these cases, a hepatoportocholecystostomy (HPC) may be performed instead of the classical hepatoportoenterostomy (HPE).

TGF-beta1 from Endometriomas Promotes Fibrosis in Surrounding Ovarian Tissues via Smad2/3 Signaling.

To elucidate whether the endometriotic cells of endometriomas synthesize transforming growth factor beta1 (TGF-beta1) and understand how it affects surrounding ovarian tissue. We collected biopsies of the cystic walls from 42 endometriomas and 29 mature teratomas and compared mRNA and protein expression of fibrosis-related factors between the cystic walls. Then we detected TGFB1 mRNA synthesis in endometriomas, and tested TGF-beta1 fibrotic effect in vitro. Moreover, we verified the expression of Smad2/3 Si...
