Default principal diagnosis: inpatient Yes · outpatient Yes

Clinical InformationClinical

  • Angiolymphoid Hyperplasia with Eosinophilia

    solitary or multiple benign cutaneous nodules comprised of immature and mature vascular structures intermingled with endothelial cells and a varied infiltrate of eosinophils, histiocytes, lymphocytes, and mast cells.

  • 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.

  • Venous Lake

    a condition that is characterized by venous dilation, which presents as soft, compressible lesions.

  • Glomangiomyoma

    a morphologic variant of the glomus tumor with architectural features similar to solid glomus tumor. it is characterized by the presence of elongated glomus cells which resemble mature smooth muscle.

Patient EducationClinical

Benign Tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
