Civatte bodies histology

A Civatte body (named after the French dermatologist Achille Civatte, 1877–1956) is a damaged basal keratinocyte that has undergone apoptosis, and consist largely of keratin intermediate filaments, and are almost invariably covered with immunoglobulins, mainly IgM. Civatte, Achille, French dermatologist, 1877-1956. 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 SUMMARY The relationship between Civatte bodies and epithelial cells in mitosis was investigated in lichen planus lesions of the oral mucosa. The nuclear material in Civatte bodies was often very s Civatte bodies (CBs) are seen as rounded, homogenous, eosinophilic masses on routine H and E staining lying in the deeper parts of epidermis/epithelium and more frequently in dermis/connective tissue. They are known as CBs (in epithelium/epidermis), colloid bodies, or hyaline bodies (in connective tissue). Civatte bodies.

These structures are universally known as Civatte bodies. Nonetheless, they were first described by Raymond Sabouraud in 1912. Even after Achille Civatte discussed and beautifully illustrated them a decade later, it took until the late 1960s for the term Civatte body to win acceptance.

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. ‘ Hyaline bodies’ are equivalent but occur in connective tissue.

In other words, any mass found in an organ or tissue in which it does not [Histologic and immunofluorescence microscopy phenomena of keratin (Civatte) bodies of PUVA treated cutaneous lichen ruber planus]. [Article in German] Narwutsch M, Narwutsch M. In a histological and immunofluorescence microscopic study on 145 patients suffering from lichen planus the PUVA-effects on the keratin bodies are observed. Civatte bodies though are one of the key features in the four major histological changes in lichenoid dermatoses histopathologically they were found to be less correlated in ours as well in other similar studies (Hegde and Khadilkar, 2014). Caspary-Joseph spaces were seen in very few cases (2.5%) in our study. Often vacuolar degeneration of basal keratinocytes and apoptotic bodies (colloid or Civatte bodies).
