Case History: M/22, presented with left inguinal mass and two lung nodules.
Intended diagnosis: Metastatic teratoma in lung. Contributed by:FML
Code Diagnosis Comment Score
anonymous Lung - Consistent with metastatic germ cell tumour(100%) The morphology is mature teratoma in the lung nodule, but the exact classification of the primary germ cell tumour depends on the histology of the testicular tumour/inguinal mass.  100
anonymous Metastatic teratoma, compatible with testicular primary, 100% Suggest correlation with pathology of inguinal mass  100
anonymous Metastatic germ cell tumor (mature teratoma). 100% Need to correlate with the histology of the primary tumor, which may or may not be morphologically identical. Also check if chemotherapy has been administered.  100
anonymous LUNG : IMMATURE TERATOMA, probably metastatic from a germ cell tumour of a maldescended left testis (100%). The nature of the left inguinal mass should be confirmed with biopsy and/or fine needle aspiration.  100
anonymous Teratoma (predominantly mature), most likely metastatic from a testicular primary Nature of inguinal/testicular mass has to be determined for comparison  100
anonymous METASTATIC TERATOMA. 100% Post-pubertal/adult teratoma of testis is associated with unfavorable prognosis.  100
anonymous Immature teratoma, with the clinical history, suggestive of metastasis from probable undescended testis with teratoma or teratocarcinoma. (100%) nil  100
anonymous Lung nodule - teratoma, favour metastatic 100% The lung lesion shows mature elements but require adequate sampling to rule out immature or other germ cell components. Pathology of the left inguinal mass should be correlated (? undescended testis harbouring germ cell tumour). The full history of therapy is also relevant as chemotherapy can induce maturation of teratomatous tissue.  100
anonymous Immature teratoma, metastatic to lung 100% The left inguinal mass likely represents a primary germ cell tumour probably arising from an undescended testis.  100
anonymous Metastatic teratoma 100% nil  100
anonymous Metastatic Germ Cell Tumour with mature teratomatous components only. 100% More blocks to look for other component. Metastasis must be excluded.  100
anonymous Metastatic immature teratoma (100%) nil  100
anonymous Metastatic immature teratoma, please look for primary from testis. Probability : 100% nil  100
anonymous Teratoma with mature elements 100% Metastatic teratoma from gonadal primary has to be considered and correlation with histology of the inguinal mass is necessary.  100
anonymous Metastatic teratoma, with immature components 100% nil  100
