These usually present with per vaginal bleeding and vaginal mass. Presentation with discharged tumor fragments is very unusual. [ncbi.nlm.nih.gov]

• Soft Tissue Mass

  Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a lobulated soft tissue mass in paranasal sinus that extended to oral cavity, nasopharynx, and oropharynx. [ncbi.nlm.nih.gov]

  Pelvic sonography showed a echogenic soft tissue mass posterior to the urinary bladder and inferior to the uterus which extended inferiorly, measuring 4x 3.5 x 2.7 cms, suggestive of an intravaginal mass. Rest of the abdomen was normal. [ijri.org]

  Computed tomography (CT) head and neck revealed a large solid soft tissue mass with cystic areas causing destruction of the left mandible [Figure 1] a]. [cancerjournal.net]

  Abstract We are presenting a case of a 13-year-old girl with a chief complaint of lower abdominal pain. A computed tomographic scan showed a 10-cm right ovarian mass. The serologic testing showed high alpha-fetoprotein level. [ncbi.nlm.nih.gov]

  pain in the right fossa. [jbsr.be]

  The patients presented with abdominal pain and swelling. Their serum AFP level was elevated. Seven tumors were unilateral, one was bilateral and three had extraovarian spread. [ijpmonline.org]

  A typical presentation is abdominal pain and a large, unilateral, rapidly growing pelvic mass. In about 10% of patients, rupture or torsion of the tumor occurs. [path.upmc.edu]

• Nausea

  When symptoms do occur, they may include the following: Nausea Vomiting Headache Cough Fever Changes in bowel function or habits Fatigue Problems with breathing Weight loss Night sweats Symptoms for location-specific endodermal sinus tumor may include [stjude.org]

• Suprapubic Pain

  We describe a case of a 26-year man with complaints of suprapubic pain and burning micturition for two weeks and intermittent hematuria for two months. On physical examination, there was palpable mobile pelvic mass measuring 10x10 cm. [ncbi.nlm.nih.gov]

• Left Ventricular Dysfunction

  However, she also suffered from severe non-hematological toxicities, including grade 3 left ventricular dysfunction and grade 4 pulmonary fibrosis. [ncbi.nlm.nih.gov]

• Jaundice

  We describe an 11-month-old girl with a YST arising from the CBD who presented with obstructive jaundice. [ncbi.nlm.nih.gov]

  The primary yolk sac tumor of the liver usually presents with abdominal pain, an abdominal lump, and less frequently, jaundice. The serum AFP is usually highly increased in these tumors. [journals.lww.com]

  A previously healthy 20-year-old man, consulted to the emergency department for two days of emesis and abdominal pain associated with jaundice. On physical exam, the patient was stable, conscious and icteric. [omicsonline.org]

  There was no jaundice and lymphadenopathy. Systemic examination was unremarkable. A lump was palpable in right lower abdomen. It was soft to firm, tender and 16-20 weeks uterine size. [turkjpath.org]

• Subcutaneous Nodule

  We report a case of an 11-month-old female with sacrococcygeal extragonadal yolk sac tumor manifesting as a draining subcutaneous nodule after initial treatment as an abscess. [ncbi.nlm.nih.gov]

• Testicular Mass

  MRI Heterogeneous testicular mass lesion with post-contrast heterogeneous enhancement, with areas of hemorrhage/necrosis 2. [radiopaedia.org]

  No specific symptoms except testicular mass are present. Almost all the patients with a yolk sac tumor (YST), either in pure form or mixed form have a significantly elevated serum alpha fetoprotein (AFP). [emedicine.medscape.com]

  On the second day in intensive care unit, physical examination revealed a large right testicular mass, not painful on palpation. [omicsonline.org]

• Adnexal Mass

  The patients were 23, 29, and 43 years old, and all presented with large unilateral adnexal masses confined to the ovary. One tumor was predominantly cystic, and the other 2 had prominent cystic components; all 3 also had solid components. [ncbi.nlm.nih.gov]

  Fine needle aspiration (FNA) was performed from the right adnexal mass and peritoneum using a 22-G needle. [biocoreopen.org]

  US characterizes the adnexal mass and shows ascites or hepatic metastasis. CT scan detects carcinosis and adenopathy, MRI reveals the hyper-vascularized and hemorrhagic feature of the mass ( 36 ). [frontiersin.org]

• Oliguria

  Chemotherapy with BEP was started, and after 24 h of administration, oliguria and tumor lysis syndrome (TLS) developed. [ncbi.nlm.nih.gov]

• Burning Micturition

  We describe a case of a 26-year man with complaints of suprapubic pain and burning micturition for two weeks and intermittent hematuria for two months. On physical examination, there was palpable mobile pelvic mass measuring 10x10 cm. [ncbi.nlm.nih.gov]

• Primary Amenorrhea

  This neoplasm occurred in young patients who often displayed phenotypic sex ambiguities and frequently presented with primary amenorrhea. [ncbi.nlm.nih.gov]

• Headache

  A 55-year-old man with progressive left side weakness, headache, dizziness and ataxia, underwent preoperative magnetic resonance imaging, diffusion-weighted imaging and proton magnetic resonance spectroscopy. [ncbi.nlm.nih.gov]

• Neglect

  Furthermore, it is important to investigate more thoroughly a patient with history of intermittent abdominal pain and fever with previously multiple accesses, because these might be the critical signs for YST that should not be neglected in order to treat [frontiersin.org]

CONCLUSIONS This unique presentation of a yolk sac tumor emphasizes the need to keep a broad differential and complete a thorough workup for any cardiac mass. [ncbi.nlm.nih.gov]

AFP No discussion (or diagnostic workup) of yolk sac tumor is complete without considering alpha-fetoprotein (AFP). AFP is a protein produced predominantly by the yolk sac and fetal liver. [pathologystudent.com]

His symptom was caused by a ruptured massive intraabdominal tumor into the pleural space, which was identified during radiological workup. [jscimedcentral.com]

• Anisocytosis

  Individual cells were large, showing moderate anisocytosis, high nucleocytoplasmic ratio. The nuclei were round to oval with irregular nuclear membranes, coarsely clumped chromatin and 0-1 nucleoli. [jcytol.org]

• Gastric Lesion

  The patient was diagnosed with gastric YST with synchronous liver metastasis and underwent simultaneous resection of the primary gastric lesion and liver metastasis successfully. [tcr.amegroups.com]

• Lymphocytic Infiltrate

  A myxoid background (39%), lymphocytic infiltrate (17%), and an appliqué pattern (8%) were sometimes observed. [ncbi.nlm.nih.gov]

  Seminoma cells are bigger that YST cells, with lymphocytic infiltrates. Juvenile granulosa cell tumor (JGCT) should be distinguished from yolk sac tumors (YSTs) because of their morphologic similarities. [emedicine.medscape.com]

Before the late 1970s, when innovative chemo treatments began, endodermal sinus tumor was almost always fatal. Without treatment, it spreads quickly in children and will lead to death. [stjude.org]

With this salvage treatment, she remained in complete remission and disease-free for more than 30 months, while maintaining her reproductive function. [ncbi.nlm.nih.gov]

Postmenopausal ovarian YSTs are aggressive, and may have a worse prognosis compared with those in young patients. More aggressive treatment is needed. [ncbi.nlm.nih.gov]

We review the previous literature and discuss the etiology, histology, treatment, and the prognosis of the rare sinonasal yolk sac tumor. [ncbi.nlm.nih.gov]

Etiology Totipotent cells, which later form extraembryonic fetal membranes, give rise to yolk sac tumors. Features Perivascular structures called Schiller-Duval bodies can be found in 50% of tumors and are pathognomonic. [radiopaedia.org]
