Civatte (colloid) bodies may be found along the dermal-epidermal junction or within the keratinocyte layer. Epidermal Atrophy If the lesion is longstanding, the epidermis may atrophy secondary to repeated destruction of basal cells by the inflammatory infiltrate. The number of evaluatable K17+ Civatte bodies from the 56 oral lichen planus cases (biopsy specimens) containing Civatte bodies totalled 481, while frequency based on location was 254 (52.8%) in Necrotic basal cell in dermis = colloid bodies = Civatte bodies. Pink bodies approximately the size of a keratinocyte. Notes: Hyperkeratosis and hypergranulosis are not seen in erythema multiforme. Colloid bodies = cytoid bodies = Civatte bodies = hyaline bodies = apoptotic bodies.

Civatte bodies pathology outlines

The histologic features are consistent with lichen planus. If this is a solitary lesion, a benign lichenoid keratosis is favored. Dyskeratotic keratinocytes are frequently seen at the basal layer. Dyskeratotic keratinocytes (so called Civatte bodies) are frequently seen at the basal layer. Civatte bodies are PAS positive.

CMs are the So-called Civatte bodies were investigated with light and electron microscopes in six patients with Riehl's melanosis. They were present in the lower part of the epidermis and/or in the upper dermis of the lesions of all patients. In the epidermis they were composed of wavily arranged fine filaments and entangled melanosomes, desmosomes and other cell organelles. In the dermis Civatte bodies In pathology, a Councilman body, also known as Councilman hyaline body or apoptotic body, is an acidophilic (eosinophilic / pink-staining on H&E) globule of cells that represents a dying hepatocyte often surrounded by normal parenchyma.

Civatte bodies are PAS positive. Eosinophils are uncommon in conventional cutaneous lichen planus. Lichen planus may occur on mucosal surfaces such as the oral mucosa or genitalia. Apoptosis of basal layer keratinocytes results in ‘Civatte bodies’ (in lichen planus and other lichenoid type reactions) or ‘sunburn cells’ (in acute sunburn).

These structures are universally known as Civatte bodies. Nonetheless, … 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 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 . Poikiloderma of Civatte is a benign, common and chronic condition, which belongs to the group of melanodermas (pigmented skin disorders). 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.

Lichen planus may occur on mucosal surfaces such as the oral mucosa or genitalia. 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 .

Histol Histopathol 9 (4): 633-42. 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] 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. Nonetheless, they were first described by Raymond Sabouraud in 1912. Even after Achille Civatte discussed and beautifully illustrated them a Following IRB approval, cases of VH and VC from 1994 to 2014 were retrieved from the archives of UF Oral Pathology Biopsy Service. A panel of 4 board-certified oral and maxillofacial pathologists reviewed and scored the presence or absence of 5 lichenoid features: band-like infiltrate (BLI), saw tooth rete ridges (STRR), interface stomatitis (IS), civatte bodies (CB), and basement membrane 2021-04-06 So-called Civatte bodies were investigated with light and electron microscopes in six patients with Riehl's melanosis.

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. 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.
