Non seminomatous mixed germ cell tumor of the testis with predominant component of somatic type malignancy (Rhabdomyosarcoma) - A rare occurrence.

Testicular germ cell tumors (GCT) are a diverse group of neoplasms, broadly divided into seminomatous and non seminomatous types, with varying histomorphology. Mixed germ cell tumors express more than one germ cell component. Somatic type malignancy occurring in testicular GCT is rare. Most often these components present as metastasis, particularly following chemotherapy, rather than primarily involving the testis. We describe a rare case of a young adult with no significant past history, who presented with testicular mass which on histology revealed a non-seminomatous mixed germ cell tumor with additional somatic type malignancy component of a rhabdomyosarcoma.

Malignant chondroid syringoma of thigh with late metastasis to lung: A very rare case report.

Mixed/biphasic tumors include epithelial-myoepithelial tumors, pleomorphic adenoma, matrix-producing tumors, cutaneous mixed tumors such as chondroid syringoma (CS), malignant mixed tumors (carcinosarcomas), pulmonary blastomas (in lung), and many others. Morphology may show overlap between various mixed tumors. At any particular site, whether these tumors are primary or metastasis from other sites is difficult to determine, more so if primary is unknown or not disclosed. CS is a rare benign mixed/biphasic skin adnexal tumor, considered as cutaneous counterpart of pleomorphic adenoma. Its malignant variant, malignant CS is reported only occasionally. We describe a case of a 51 year old female who presented with multiple masses in both lungs. This case is a very rare example of late metastasis to lungs from a primary malignant CS of thigh.
