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 ...

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...

Cystic cervical teratoma: A diagnostic and management challenge.

Cervical teratomas are relatively rare congenital tumors pathologically defined by their three germ cell layer composition. Classically they manifest as solid or mixed solid-cystic lesions. Purely cystic teratomas pose a diagnostic challenge due to their clinical and radiologic similarity to lymphatic vascular malformations. Sclerotherapy, rather than operative excision, may be offered as therapy. We present an unusual cystic neck mass to highlight this dilemma.

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.

Vascular Smooth Muscle Cell Maturation Stage and Ki-67 Index are Diagnostic Biomarkers for Pathologic Grade of Ovarian Teratoma.

Although immature teratoma of the ovary is a rare disease, its pathologic grading, especially between low-grade (grade 1) and high-grade (grade 2 or 3) immature teratomas, is important for optimal therapy and prognosis. This grading, however, is currently solely dependent on quantitation of neuroepithelial components as judged by subjective assessments. As we have recently successfully studied the maturation of vascular smooth muscle cells (SMCs) in other organs using an h-caldesmon to α-smooth muscle acti...

Metachronous Germ Cell Tumors of the Mediastinum.

We report a rare case of mediastinal nonseminomatous germ cell tumor arising after 2 complete resections of mediastinal mature teratomas 18 and 10 years prior. After three cycles of chemotherapy for the mediastinal nonseminomatous germ cell tumor, the serum α-fetoprotein and β-human chorionic gonadotropin levels were normalized. However, chest radiography revealed that the mediastinal tumor had remarkably increased in size, and thus growing teratoma syndrome was diagnosed. The patient underwent urgent res...

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 ...

Primary Cystic Trophoblastic Tumor of the Testis: A Study of 14 Cases.

Cystic trophoblastic tumor (CTT) has been described in postchemotherapy retroperitoneal lymph node dissections of patients with testicular germ cell tumors. Prognostically, this lesion is similar to teratoma and no further treatment is required after surgery in the absence of other components. CTT has not, however, been reported in the testis. We identified 14 CTTs in the treated (4) and untreated (9; no information for 1 patient) testes of patients 15 to 43 years old (median, 25) with mixed germ cell tumor...

Mesenteric Cystic Teratoma Masquerading as Acute Abdomen.

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.

Measurement Bias of Gross Pathologic Compared With Radiologic Tumor Size of Resected Lung Adenocarcinomas: Implications for the T-Stage Revisions in the Eighth Edition of the American Joint Committee on Cancer Staging Manual.

The eighth edition of the AJCC Cancer Staging Manual now stratifies the T descriptor for lung cancers by each increasing 1.0 cm increment, up to 5.0 cm, with an additional category for tumor greater than 7.0 cm. Bias in pathologic versus radiologic measurements may impact tumor staging.

As most cases of pregnancy loss has been reported at 7-9 weeks /...

Teratoma of the nervous system: A case series.

Teratoma is a common form of germ cell tumors composed of multiple tissues foreign to the site in which arise with a histological representation of all three germ cell layers. Intracranial teratomas are very rare. In this study, we report three cases of intracranial teratomas with an interesting clinical course, neuroradiology, and outcome. In addition, we review the literature and convey important messages to the neuroscience community regarding issues related to the management of these rare tumors. The pr...

Primary spinal glioblastoma multiforme: A case report and review of the literature.

Primary spinal glioblastoma multiforme (GBM) is a rare clinical entity with an aggressive course and an invariably dismal prognosis. Its clinical characteristics, radiologic and pathologic findings, and treatment protocols have been discussed in a few cases.

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 ...
