Lichen planus — there are some overlapping features including interface activity and Civatte body formation. However, the latter is usually more conspicuous in lichen planus. Mucous membrane lesions are particularly difficult to distinguish.

Civatte body Civatte body A Civatte body (named after the French dermatologist Achille Civatte, 1877–1956) [35] 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. [36]

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. Journal.

On the glans penis it was referred to as balanitis xerotica obliterans, abbreviated BXO. These bodies are similar in their composition to the Kamino bodies of Spitz's nevi, cylindrical bodies in adenoid cystic carcinoma, Civatte bodies of lichen planus, and the collagenous spherules seen in a number of conditions, and may provide a unique clue to the diagnosis of the porphyric bullous eruptions. Civatte bodies' are present in the lower part of the epidermis and are composed of net like amorphous masses. When present in the epidermis, these bodies are composed of waverly arranged fine filaments entangled with melanosomes, desmosomes and other organelles.

PMID: 8100120 [Indexed for MEDLINE] These results indicate that K17 is a sensitive immunohistochemical marker for Civatte bodies and useful for differential diagnosis of oral lichen planus from other oral mucosal lesions. Civatte bodies are generated from denucleation of K17+ epithelial cells during the process of cell death via dyskeratosis, which is possibly related to blood capillary collapse. # Tiny linear or arc-shaped bodies, amporphous, brittle and eosinophilic in reaction, found in association with some odontogenic cysts, are called: A. Civatte bodies B. Russel Bodies C. Guarneri Bodies D. Rushton bodies # The cells most frequently found in a granuloma are: A. Mast cells B. Giant cells C.

Dead keratinocytes (Civatte bodies).

Often vacuolar degeneration of basal keratinocytes and apoptotic bodies (colloid or Civatte bodies). Lichen planus Irregular epidermal hyperplasia with a jagged “sawtooth” appearance, compact hyperkeratosis or orthokeratosis, foci of wedge-shaped hypergranulosis, basilar vacuolar degeneration, slight spongiosis in the spinous layer, and squamatization.

1980 Oct;7(5):323-33. Electron microscopic studies of porokeratosis Mibelli --Civatte bodies and amyloid deposits in the dermis. 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.

There is folliculocentric lichenoid infiltrate at the level of the infundibulum sparing the lower portion, and damage of the outer epithelial sheath of the follicles. Civatte bodies were not confined to the basal layer. The findings suggest that cell-mediated regression may occur in common warts, similar to that described in plane warts. Warts treated with injections of bleomycin show confluent epidermal necrosis, single apoptotic keratinocytes, and diffuse neutrophil infiltration of the epidermis, with abscess formation in the granular layer.
