Minimally invasive adenocarcinoma of the lung

Minimally invasive adenocarcinoma of the lung is defined as a small, solitary tumour with predominant alveolar epithelial appearance, as in situ adenocarcinoma of the lung, with a zone of focal invasion of the chorion, with a size inferior to 5 mm. For MIA - as with adenocarcinoma in situ -, the prognosis is near 100% survival.

Mixed-cell lymphoma

Mixed-cell lymphomas are lymphomas that have both large cells and small cells in them. This nomenclature is derived from an older system of pathology, before technological advances allowed much more precise descriptions of the affected cancerous cells.
In mesh, the phrase "mixed-cell lymphoma" is currently attributed to non-Hodgkins lymphoma.

Monocytic leukemia

Monocytic leukemia is a type of myeloid leukemia characterized by a dominance of monocytes in the marrow. When the monocytic cells are predominantly monoblasts, it can be subclassified into acute monoblastic leukemia.

Acute monocytic leukemia. (Острый моноцитарный лейкоз)
Chronic myelomonocytic leukemia. (Хронический миеломоноцитарный лейкоз)

Leiomyosarcoma is a sarcoma of smooth muscle, rhabdomyosarcoma and sarcoma of striated muscle. However, the term myosarcoma still appears in the literature.

Nerve sheath tumor

A nerve sheath tumor is a type of tumor of the nervous system which is made up primarily of the myelin surrounding nerves.
In peripheral nerve sheath tumors pnst application of nerve sheath tumors in the peripheral nervous system. Benign tumor of the peripheral nerve sheath include schwannoma and neurofibromas.
Malignant tumor of peripheral nerve sheath MPNST is a cancer of the peripheral nerve sheath.

Neurocytoma

Neurocytoma is a type of nervous system benign tumor which is primarily derived from nervous tissue. This is in contrast to the gliomas, which are derived from glial cells, and not from nervous tissue.

Serous cystadenocarcinoma is a type of tumor in the cystadenocarcinoma grouping.
Most often, the primary site of serous cystadenocarcinoma is the ovary. A rare occurrence in the pancreas has been reported, although this is not typical of the majority of microcystic pancreatic mass representing alternative disease process, such as more benign serous cystadenoma.
