Who Described Civatte Bodies? Who Described Civatte Bodies? Burgdorf, Walter H. C.; Plewig, Gerd 2014-04-01 00:00:00 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. 2020-06-30 · The distal ventral surface is the eponychium.

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.

2020-06-30 · The distal ventral surface is the eponychium. At the angle between the dorsal and ventral surfaces of the PNF, the eponychium produces the cuticle, a thick stratum corneum layer that firmly adheres to the nail plate. [2] [13] The cuticle forms a seal to protect the matrix from toxins and microbes. 2020-09-03 · 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 philic, were identified as colloid bodies (also known as apoptotic or Civatte bodies)1° in 23 biopsies and in 21 dogs (58%) (Table 1).

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

Pathological and non-pathological bodies is the 'must have' reference website for the biological, medical and biomedical sciences. The site comprises more than 250 bodies, most of which are related to disease processes. 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.

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).

A punch biopsy can show typical histology with hyperkeratosis, epidermal atrophy, pigmentary incontinence, telangiectasia, a variable superficial dermal lymphohistiocytic infiltrate, and solar elastosis. 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.
