transient erythroblastopenia of childhood
Pronunciation: eh-rith-roh-blas-toh-PEE-nee-ah
Also written as: TEC — transient erythroblastopenia of childhood
A temporary condition in young children characterized by severe anemia due to decreased red blood cell production that typically resolves spontaneously.
Full Definition
Transient erythroblastopenia of childhood (TEC) is an acquired, temporary condition affecting children typically between 6 months and 4 years of age, characterized by severe normocytic anemia due to decreased erythroid production in the bone marrow. Unlike Diamond-Blackfan anemia, TEC patients have normal or elevated erythropoietin levels, absence of congenital abnormalities, and normal MCV for age. The condition often follows a viral infection and typically resolves spontaneously within 1-2 months without specific treatment. Reticulocytes are characteristically low initially but increase as recovery begins, serving as a key diagnostic and prognostic marker.
Usage
Usage note: Often abbreviated as TEC; emphasize 'transient' nature to distinguish from chronic conditions.
