Label	Id	Description
Hemangiosarcoma	D006394	[A rare malignant neoplasm characterized by rapidly proliferating, extensively infiltrating, anaplastic cells derived from blood vessels and lining irregular blood-filled or lumpy spaces. (Stedman, 25th ed)]
Hemarthrosis	D006395	[Bleeding into the joints. It may arise from trauma or spontaneously in patients with hemophilia.]
Hematemesis	D006396	[Vomiting of blood that is either fresh bright red, or older "coffee-ground" in character. It generally indicates bleeding of the UPPER GASTROINTESTINAL TRACT.]
Hematocele	D006398	[Hemorrhage into a canal or cavity of the body, such as the space covered by the serous membrane (tunica vaginalis) around the TESTIS leading to testicular hematocele or scrotal hematocele.]
Hematocolpos	D006399	[A blood-filled VAGINA that is obstructed.]
Hematologic Diseases	D006402	[Disorders of the blood and blood forming tissues.]
Hematologic Neoplasms	D019337	[Neoplasms located in the blood and blood-forming tissue (the bone marrow and lymphatic tissue). The commonest forms are the various types of LEUKEMIA, of LYMPHOMA, and of the progressive, life-threatening forms of the MYELODYSPLASTIC SYNDROMES.]
Hematoma	D006406	[A collection of blood outside the BLOOD VESSELS. Hematoma can be localized in an organ, space, or tissue.]
Hematoma, Epidural, Cranial	D006407	[Accumulation of blood in the EPIDURAL SPACE between the SKULL and the DURA MATER, often as a result of bleeding from the MENINGEAL ARTERIES associated with a temporal or parietal bone fracture. Epidural hematoma tends to expand rapidly, compressing the dura and underlying brain. Clinical features may include HEADACHE; VOMITING; HEMIPARESIS; and impaired mental function.]
Hematoma, Epidural, Spinal	D046748	[A rare epidural hematoma in the spinal epidural space, usually due to a vascular malformation (CENTRAL NERVOUS SYSTEM VASCULAR MALFORMATIONS) or TRAUMA. Spontaneous spinal epidural hematoma is a neurologic emergency due to a rapidly evolving compressive MYELOPATHY.]
Hematoma, Subdural	D006408	[Accumulation of blood in the SUBDURAL SPACE between the DURA MATER and the arachnoidal layer of the MENINGES. This condition primarily occurs over the surface of a CEREBRAL HEMISPHERE, but may develop in the spinal canal (HEMATOMA, SUBDURAL, SPINAL). Subdural hematoma can be classified as the acute or the chronic form, with immediate or delayed symptom onset, respectively. Symptoms may include loss of consciousness, severe HEADACHE, and deteriorating mental status.]
Hematoma, Subdural, Acute	D020199	[Accumulation of blood in the SUBDURAL SPACE with acute onset of neurological symptoms. Symptoms may include loss of consciousness, severe HEADACHE, and deteriorating mental status.]
Hematoma, Subdural, Chronic	D020200	[Accumulation of blood in the SUBDURAL SPACE with delayed onset of neurological symptoms. Symptoms may include loss of consciousness, severe HEADACHE, and deteriorating mental status.]
Hematoma, Subdural, Intracranial	D046648	[Accumulation of blood in the SUBDURAL SPACE over the CEREBRAL HEMISPHERE.]
Hematoma, Subdural, Spinal	D046649	[Subdural hematoma of the SPINAL CANAL.]
Hematometra	D006409	[Blood-filled UTERUS.]
Hematuria	D006417	[Presence of blood in the urine.]
Hemianopsia	D006423	[Partial or complete loss of vision in one half of the visual field(s) of one or both eyes. Subtypes include altitudinal hemianopsia, characterized by a visual defect above or below the horizontal meridian of the visual field. Homonymous hemianopsia refers to a visual defect that affects both eyes equally, and occurs either to the left or right of the midline of the visual field. Binasal hemianopsia consists of loss of vision in the nasal hemifields of both eyes. Bitemporal hemianopsia is the bilateral loss of vision in the temporal fields. Quadrantanopsia refers to loss of vision in one quarter of the visual field in one or both eyes.]
Hemic and Lymphatic Diseases	D006425	[Hematologic diseases and diseases of the lymphatic system collectively. Hemic diseases include disorders involving the formed elements (e.g., ERYTHROCYTE AGGREGATION, INTRAVASCULAR) and chemical components (e.g., BLOOD PROTEIN DISORDERS); lymphatic diseases include disorders relating to lymph, lymph nodes, and lymphocytes.]
Hemifacial Spasm	D019569	[Recurrent clonic contraction of facial muscles, restricted to one side. It may occur as a manifestation of compressive lesions involving the seventh cranial nerve (FACIAL NERVE DISEASES), during recovery from BELL PALSY, or in association with other disorders. (From Adams et al., Principles of Neurology, 6th ed, p1378)]
