A 58-year-old male patient presented with a recurrent true malignant mixed tumor of the parotid gland. Patchy pulmonary opacities were identified with a chest radiograph. Subsequently, a CT scan of the chest showed pulmonary parenchymal consolidation with amorphous calcifications. This abnormality was confirmed to be the result of a metastatic true malignant mixed tumor by using CT-guided biopsy. The current case demonstrated an extremely rare example of atypical pulmonary metastases from a true malignant mixed tumor of the parotid gland showing an air-space pattern and calcification.

A female aged 49 years presented with pain and progressive swelling of right lower abdomen. She was operated upon and gross examination revealed a proliferative growth in the fimbrial end of the right fallopian tube. Microscopically the tumour comprised of adenocarcinoma and component of spindle cell stromal sarcoma with areas of chondrosarcoma as heterologous element. A diagnosis of malignant mixed mullerian tumour of the fallopian tube, clinically FIGO stage III was made, which is extremely rare in available literature.

A 15 year old boy presented with diminution in vision of both eyes, diabetes insipidus and hypopituitarism. MRI was suggestive of a large suprasellar and retrosellar craniopharyngioma with stretching of the optic chiasma. Histopathological findings on the first surgical specimen were interpreted as a craniopharyngioma. He was reoperated on account of clinical deterioration and increase in tumour size. Histological examination this time revealed derivatives of all three germ cell lineages along with areas of embryonal carcinoma, and yolk sac tumour besides squamous cysts, establishing the diagnosis of malignant mixed germ cell tumour. Serum and CSF were strongly positive for alpha foetoproteins.

Se analizaron retrospectivamente, 104 lesiones de la glándula lagrimal en un período de 40 años comprendido entre 1957 y 1996. Del total, 21 casos correspondieron a neoplasias malignas, todas ellas de origen epitelial; 38 casos a quistes (dacriops), 16 casos a tumores benignos y 28 casos a glándula lagrimal normal. Sólo se encontró un caso de proceso inflamatorio o dicrioadenitis crónica

Primary carcinoma of the uterine tubes is one of the rare genital malignancies constituting 0.1% - 0.5% of gynaecological cancer and malignant mixed mullerian tumour is the rarest among them. Recently such a case was diagnosed and managed in our institution, because of its rarity it is reported here
