Like Civatte bodies, they were PAS-positive and were particularly well-demonstrated by this stain (color Fig 2). The patientwas Introduction 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). In the absence of a clear diagnosis, their presence is suggestive of disorders characterized by interface dermatitis. The frequency, number and arrangement of civatte bodies in clusters in the papillary dermis as well as multiple immunoglobulins deposition at the civatte bodies on direct immunofluorescence of skin biopsies are important features distinguishing lichen planus from other interface dermatitis. 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 Lichen planus (LP) is a chronic inflammatory and immune-mediated disease that affects the skin, nails, hair, and mucous membranes.

Biopsy from lip shows focal parakeratosis, hypergranulosis (blue arrow), interface dermatitis (yellow star), Civatte bodies, and pigment incontinence, suggestive of lichen planus (H&E, ×100). Lichen Planus Introduction Lichen Planus is an rare, recurrent, inflammatory condition of the skin and mucous membranes with unknown origin characterized by shiny reddish-purple spots on the skin and gray-white ones in the mouth. “Pruritic, purple, polygonal, planar papules, and plaques” are the tongue-twisting Ps that describe this disorder of skin and squamous mucosa. The lesions […] 2016-07-01 · These were common in hypertrophic lichen planus, follicular lichen planus or lichen plano pilaris lichenoid drug eruptions, and lichen striatus in our study. Out of the various parameters we analyzed sensitivity and specificity and found that sensitivity was the highest in basement membrane degeneration and specificity was maximum observed in civatte bodies (though its sensitivity was low).

The patientwas Direct immunofluorescence (DIF) will distinguish hypertrophic lupus erythematosus (continuous granular band of immunoglobulins and complement plus cytoid bodies) from lichen planus (shaggy fibrin, cytoid bodies). When parakeratosis is present, lichen planus is very unlikely.

In oral lichen planus, approximately 1 apoptotic cell was detected per millimeter larger hyaline structures termed colloid bodies , or Civatte bodies , is unclear,

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.

Lichen planus (LP) affects mucocutaneous surfaces and is characterized by intraepithelial and lamina propria lymphocytosis and squamous cell apoptosis (Civatte bodies). Lichen planus esophagitis (LPE) is underrecognized; concurrent cutaneous disease is present in some patients, but LPE alone is more common. We diagnose patients with characteristic pathologic findings of LPE and known

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, also known as colloid bodies or hyaline bodies, are regarded as a diagnostic hallmark for lichen planus 5. 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).

[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. Biopsies revealed Civatte bodies and a lymphocytic infiltration consistent with esophageal lichen planus . She underwent dilatation of the stricture and was commenced on fluticasone proprionate at a dose of 1000 µg daily, swallowed rather than inhaled, in two divided doses. 2015-08-03 · Direct immunofluorescence (DIF) will distinguish hypertrophic lupus erythematosus (continuous granular band of immunoglobulins and complement plus cytoid bodies) from lichen planus (shaggy fibrin, cytoid bodies).

Comment: Sections show acanthosis, hypergranulosis and a lichenoid infiltrate with Civatte bodies. The histologic features are consistent with lichen planus. If this is a solitary lesion, a benign lichenoid keratosis is favored.

Resultant dyskeratosis is represented by the presence of necrotic keratinocytes (Civatte bodies or cytoid bodies), which are extruded into the papillary dermis. Clinical and histopathological spectrum of lichen planus

A scoop shave biopsy was performed and demonstrated the following histological features: compact hyperkeratosis, epidermal hyperplasia, vertically oriented collagen in the papillary dermis, and civatte bodies near the tips of rete ridges, consistent with hypertrophic lichen planus (Figure 3). Lichen planus (LP) is an acutely occurring inflammatory cutaneous disease frequently with a chronic course. It is characterized by erythematous to deeply purple lichenoid, planar, polygonal papules with thin, translucent and densely adherent scales. Lesions most commonly occur on the skin, oral mucosa and genital areas.
