Dyskeratotic keratinocytes (so called Civatte bodies) are frequently seen at the basal layer. Civatte bodies are PAS positive.
Functionally, the subcutaneous fat insulates the body, absorbs trauma, and a skin biopsy which yields histologic information that can be correlated with the cellules claires of Degos and Civatte, Degos acanthoma, pale cell acanthoma)
Civatte bodies are PAS positive. Eosinophils are uncommon in conventional cutaneous lichen planus.
Civatte bodies (CBs) are found in various characteristic skin lesions, and their presence is suggestive of disorders characterized by interface dermatitis.
Poikiloderma of Civatte is a benign skin condition that was first described in 1923 by Civatte, a French dermatologist.Also known as sun aging, this is a medical condition that appears as a direct result of the chronic exposure to the sun, affecting primarily the neck and chest area. CIVATTE BODIES AND APOPTOSIS CIVATTE BODIES AND APOPTOSIS WEEDON, DAVID 1974-09-01 00:00:00 SIR, The ultrastructure of Civatte bodies in lichen planus, as illustrated in the recent paper by ElLabban & Kramer (1974), is typical of 'apoptosis', the morphologically distinct type of cellular death described by Kerr, Wyllie & Currie (1972). 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 2010-11-30 · Buscaino bodies are thought to be caused by solubilization and subsequent precipitation (by fixation) of some myelin component (Ibrahim and Levine 1967).
Results: There were 34 females (68%) and 16 males. The mean age at diagnosis was 47.8 years for females and 61.7 years for males. Histological examination revealed an atrophic (62%), flattened (84%) epidermis with hyperkeratosis (92%) and occasional follicular plugging (34%). These structures are universally known as Civatte bodies.

How is poikiloderma of Civatte diagnosed? The diagnosis of poikiloderma of Civatte is made clinically. A punch biopsy can show typical histology with hyperkeratosis, epidermal atrophy, pigmentary incontinence, telangiectasia, a variable superficial dermal lymphohistiocytic infiltrate, and solar elastosis.

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. 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. poikiloderma of Civatte - reticulated pigmentation and telangiectasia of the sides of the cheeks SUMMARY The relationship between Civatte bodies and epithelial cells in mitosis was investigated in lichen planus lesions of the oral mucosa. The nuclear material in Civatte bodies was often very s 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).
chromoendoscopy, the authors demonstrated adequate histologic criteria to confirm lium, and necrotic keratinocytes (Civatte bodies). The biopsies were all
Notes: Hyperkeratosis and hypergranulosis are not seen in erythema multiforme. Colloid bodies = cytoid bodies = Civatte bodies = hyaline bodies = apoptotic bodies. Findings that help support a diagnosis of ELP include a band-like lymphocytic infiltrate involving the superficial lamina propria and basal epithelium along with the presence of Civatte bodies [7, 8]. 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. (iv) disposing of residual bodies.
  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). The generic term colloid body was preferred as Civatte bodies are traditionally found in lichen planus and related disorders, and apoptosis by definition implies a normal or physiological cellular degeneration. The basal bodies are centrioles and have 9 triplets of microtubules with no central pair. 170 Kidney - Cortex, proximal tuble Brush Border View Virtual EM Slide This EM micrograph depicts the typical appearance of microvilli on the apical surface of two types of cells with a striated or brush border.
