Other neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue (D47)

Browse all the diagnosis codes used for other neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue (d47). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Castleman Disease - Large benign, hyperplastic lymph nodes. The more common hyaline vascular subtype is characterized by small hyaline vascular follicles and interfollicular capillary proliferations. Plasma cells are often present and represent another subtype with the plasma cells containing IgM and IMMUNOGLOBULIN A.

Cytokines - Non-antibody proteins secreted by inflammatory leukocytes and some non-leukocytic cells, that act as intercellular mediators. They differ from classical hormones in that they are produced by a number of tissue or cell types rather than by specialized glands. They generally act locally in a paracrine or autocrine rather than endocrine manner.

Dysgammaglobulinemia - An immunologic deficiency state characterized by selective deficiencies of one or more, but not all, classes of immunoglobulins.

Mast Cells - Granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. Like the BASOPHILS, mast cells contain large amounts of HISTAMINE and HEPARIN. Unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. Mast cells, derived from the bone marrow stem cells, are regulated by the STEM CELL FACTOR.

Mast-Cell Sarcoma - A unifocal malignant tumor that consists of atypical pathological MAST CELLS without systemic involvement. It causes local destructive growth in organs other than in skin or bone marrow.

Mastocytoma - A solid tumor consisting of a dense infiltration of MAST CELLS. It is generally benign.

Mastocytoma, Skin - A variant of cutaneous mastocytosis which occurs as a single lesion usually in infants. It is found mostly in the wrist and trunk and there is no atypical cytomorphology.

POEMS Syndrome - A multisystemic disorder characterized by a sensorimotor polyneuropathy (POLYNEUROPATHIES), organomegaly, endocrinopathy, monoclonal gammopathy, and pigmentary skin changes. Other clinical features which may be present include EDEMA; CACHEXIA; microangiopathic glomerulopathy; pulmonary hypertension (HYPERTENSION, PULMONARY); cutaneous necrosis; THROMBOCYTOSIS; and POLYCYTHEMIA. This disorder is frequently associated with osteosclerotic myeloma. (From Adams et al., Principles of Neurology, 6th ed, p1335; Rev Med Interne 1997;18(7):553-62)

Primary Myelofibrosis - A de novo myeloproliferation arising from an abnormal stem cell. It is characterized by the replacement of bone marrow by fibrous tissue, a process that is mediated by CYTOKINES arising from the abnormal clone.

Schnitzler Syndrome - An extremely rare condition manifested as monoclonal IMMUNOGLOBULIN M dysproteinemia without features of lymphoproliferative disease, but with chronic urticaria, fever of unknown origin, disabling bone pain, hyperostosis, and increased erythrocyte sedimentation rate.

Thrombocythemia, Essential - A clinical syndrome characterized by repeated spontaneous hemorrhages and a remarkable increase in the number of circulating platelets.

Thrombocytosis - Increased numbers of platelets in the peripheral blood. (Dorland, 27th ed)
