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. Formation of Civatte bodies is thought to be due to basal cell liquefaction degeneration and hypergranulosis. 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. 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.

Functional significance of the blood-testis barrier: (i) Maintains optimal environment (nutrients, hormones) for sperm cell differentiation (ii) Isolates and protects differentiating sperm from damaging substances in the blood In histology, bodies are broadly classified into the following categories: 1. Naturally occurring body - a mass of matter found anatomically or physiologically in organs and tissues 2.

Despite multiple biopsies in this case, a diagnosis of ELP was not suggested on histopathology until deep biopsies were performed. and Beth Ruben2 (1) Pathology, Miraca Life Sciences, Irving, TX, USA (2) Dermatology and Pathology, University of California, San Francisco, CA, USA Abstract Cutaneous drug reactions can produce a variety of histopathologic inflammatory and even neoplastic patterns.

Formation→due to basal cell liquefaction degeneration and hypergranulosis 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.

[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). 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 Histology: Pink (Eosinophilic) civatte bodies in papillary dermis Pointed rete Pegs (Saw-tooth rete ridges) Causes: Phlavivirus (Flavivirus – Hepatitis C virus association) Pressure drugs (ACE inhibitors, Beta blockers, Thiazides) Plasmodium killer (Chloroquine) Penicillamine. Pigmentation after treatment 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.

Civatte bodies. Tuesday 1 June 2004. Definition: Ovoid eosinophilic formation present in squamous epitheliums in pathological conditions as lichen planus. More about this open access article on DOAJ. DOAJ is an online directory that indexes and provides access to quality open access, peer-reviewed journals. The presence of numerous civatte bodies (CBs) in biopsies is a characteristic finding in skin lesions of patients with various dermatoses, particularly lichen planus (LP) and discoid lupus erythematosus (DLE).
