These bodies are generated by damaged basal keratinocytes through apoptotic cell death, consist largely of keratin intermediate filaments, and are almost invariably covered with immunoglobulins, mainly IgM.

Civatte bodies - eosinophilic hyaline spherical bodies seen in or just beneath the epidermis, particularly in lichen planus, formed by necrosis of individual basal cells. Synonym (s): colloid bodies. poikiloderma of Civatte - reticulated pigmentation and telangiectasia of the sides of the cheeks and neck; An eponym is a word derived from the name of a person, whether real or fictional. A medical eponym is thus any word related to medicine, whose name is derived from a person. Apoptosis of basal layer keratinocytes results in ‘Civatte bodies’ (in lichen planus and other lichenoid type reactions) or ‘sunburn cells’ (in acute sunburn). Civatte body is synonymous with ‘cytoid body’, ‘colloid body’ or ‘ keratin bodies’ and refers to an eosinophilic remnant of a keratinocyte within the basal layer or upper papillary dermis . The term 'poikiloderma' refers to a skin change with atrophy where hypopigmentation / hyperpigmentation changes and dilation of the fine blood vessels (telangiectasia) can be seen in the affected skin.

Eosinophilic apoptotic (necrotic) keratinocytes in the lower epidermis and at the dermoepidermal junction are a feature of many interface dermatoses but are most reliably found in lichen planus. These structures are universally known as Civatte bodies.
