Straw colored pleural fluid with raised adenosine deaminase (ADA) levels in young healthy adults usually raises suspicion of tuberculosis, sometimes leading to laxity in carrying thorough physical examination and missing out some important clues with potential disastrous consequences. A 35-year-old male was diagnosed to have left pleural effusion and anti-tubercular treatment was started on the basis of straw colored, lymphocyte-predominant pleural fluid with significantly raised ADA levels. When there was no improvement after 1 month of treatment he was investigated further and found to have a mediastinal mass along with hydro-pneumothorax...

Germ cell tumors (GCTs) are a heterogeneous group of tumors occurring in gonadal and extragonadal locations. GCTs are hypothesized to arise from primordial germ cells (PGCs), which fail to differentiate. One recently identified susceptibility loci for human GCT is PR (PRDI-BF1 and RIZ) domain proteins 14 (PRDM14). PRDM14 is expressed in early primate PGCs and is repressed as PGCs differentiate. To examine PRDM14 in human GCTs we profiled human GCT cell lines and patient samples and discovered that PRDM14 is expressed in embryonal carcinoma cell lines, embryonal carcinomas, seminomas, intracranial germinomas and yolk sac tumors, but is not expressed in teratomas...

Sacrococcygeal yolk sac tumor is an uncommon pediatric neoplasm. It usually presents with intra-abdominal or gluteal pain and mass. At later stage, it disseminates to regional nodes and distant organs. We describe one such neoplasm in an 18-month-old male child who turned symptomatic with multiple bilateral lung metastases. The tumor produced the least deformity to his physique, to become detectable on routine inspection and clinical examination. Finally, a combined approach through clinical, radiological, pathological, and biochemical perspectives established the diagnosis...

BACKGROUND: Primary mediastinal yolk sac tumor, which is also known as endodermal sinus tumor, is a rare but lethal neoplasm, and it is a kind of mediastinal non-seminomatous germ cell tumor. The current standard treatment in mediastinal non-seminomatous germ cell tumors is chemotherapy combined with postchemotherapy residual mass resection. We report on seven cases of primary mediastinal yolk sac tumor treated with platinum-based chemotherapy and extended resection. METHODS: We experienced seven cases of primary mediastinal yolk sac tumor between August 2014 and August 2017...

Macrophages are effector cells of the innate immune system that phagocytose bacteria and secrete both pro-inflammatory and antimicrobial mediators. In addition, macrophages play an important role in eliminating diseased and damaged cells through their programmed cell death. Generally, macrophages ingest and degrade dead cells, debris, tumor cells, and foreign materials. They promote homeostasis by responding to internal and external changes within the body, not only as phagocytes, but also through trophic, regulatory, and repair functions...

Alpha Fetoprotein (AFP) producing gastric carcinomas are very rare and have unique clinicopathological features and an extremely poor prognosis. Here, we report a case of AFP producing gastric carcinoma with three distinct histomorphologic patterns such as yolk sac like, hepatoid, tubular and papillary adenocarcinoma components. The uniqueness of this case is absence of metastases and associated findings such as fundic gland polyposis with varying degrees of dysplasia, gastric and duodenal well differentiated neuroendocrine tumour and rectal ganglioneuroma...

Yolk sac tumor (YST) is the second most common subtype of ovarian germ cell tumors. It usually occurs in the second and third decades of life and is rare in postmenopausal women. In postmenopausal women, YST is commonly an aggressive tumor and can present as a pure germ cell component or as a mixed component with other germ cell or epithelial components. The recognition of this histological subtype is important not only for differential diagnosis but also for determining prognosis and treatment decisions. In this case report, we describe a 61-year-old woman with YST coexisting with epithelial carcinoma focusing on the efficacy of systemic therapies...

BACKGROUND: Melanoma, originated from melanocytes located on the basal membrane of the epithelial tissue, is the most aggressive form of skin cancer that accounts for 75% of skin cancer-related death. Although it is believed that BRAF mutation and the mitogen-activated protein kinase (MAPK) pathway play critical roles in the pathogenesis of melanoma, how the MAPK signaling is regulated in melanoma carcinogenesis is still not fully understood. METHODS: We characterized JMJD6 expression in melanoma tissue array by immunohistochemistry analysis...

Gonadoblastoma is an uncommon ovarian tumor arising primarily in females with gonadal dysgenesis and a 46, XY karyotype. Germ cell tumors arising within and/or overgrowing a gonadoblastoma have been reported. We report a rare case of a malignant mixed germ cell tumor (yolk sac tumor and choriocarcinoma) arising in a gonadoblastoma of the left ovary in a 19-year-old female with a 46, XX karyotype. The patient's initial α-fetoprotein level was 20 000 KIU/L. The patient underwent a laparoscopic unilateral salpingo-oophorectomy with omentectomy and peritoneal washing followed by adjuvant chemotherapy...

SMARCB1 (INI1) deficient sinonasal carcinoma is a recently recognized entity with wide histomorphologic spectrum. We present a case of this carcinoma that contained, in addition to a "common" morphology, scattered foci of yolk sac tumor differentiation. The tumor occurred in paranasal sinuses in a 44-year-old woman. Immunohistochemically, it was diffusely negative for INI1, whereas an expression of yolk sac tumor markers (α-fetoprotein, glypican-3, CDX2) was limited to the yolk sac tumor component. For comparison with the present case, we performed INI1 immunostaining on a series of 11 gonadal germ cell tumors with yolk sac tumor differentiation...

Yolk sac tumors (YSTs) are a type of malignant germ cell tumor that usually grow in the gonads. They are difficult to recognize at other sites outside the gonads, and no case has been reported involving the upper lip. The present study reported the case of a 13-month-old girl exhibiting an isolated YST occurring in the upper lip. The histology and elevation of α-fetoprotein were typical for a YST. The patient was cured following effective chemotherapy and surgery resection. After 36 months of follow-up, there was no sign of recurrence or metastasis...
