The focal hypergranulosis is not wedge-shaped. There are no pointed rete ridges. There is no basal squamatization. Sclerotic phase of lichen sclerosus Mention diseases that are associated with Civatte bodies (CBs). Thanks to all Civatte bodies (CBs), also known as colloid bodies, cytoid bodies and hyaline or keratin bodies, are eosinophilic hyaline Although emergence of keratin 17 (K17) and reciprocal loss of K13 are immunohistochemical hallmarks for oral mucosal malignancy, we report here findings of K17-positive (+) speckles, possibly equivalent to Civatte bodies, in benign oral lichen planus. Sixty-two biopsy samples from oral lichen planus cases were subjected to immunohistochemical examinations to analyze the distribution as well as コロイド小体（硝子様小体、Civatte bodiesなど）その他臨床病型は、網状型、びらん型、斑状型、丘疹型、紅斑型、水疱型に分類される The significance of deposition of immunoglobulin and/or complements at the dermoepidermal junction (DEJ) and civatte bodies in skin lesions of 15 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.

An eosinophilic Civatte body with a diam- eter of 10 mm may be found immediately beneath the dermis. (Fig. 2.9). Production of melanin pigment in the basal Aug 14, 2014 Singly scattered apoptotic (civatte) bodies were seen in 52 cases (41.6%) of ID. Pinkus outlined the disruption that occurs to the epidermal Mar 8, 2015 Lichenoid interface dermatitis. Key features. • Basal layer is destroyed. • Civatte bodies.

Dyskeratotic epithelial cells. Civatte bodies are usually found in subepithelial area, at the junction of the lamina propria and epithelial layer, Ismail et al. 2007 [ 22].

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. 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.

Consider Lichen Planus-like Keratosis (LPLK) Common entity, unknown etiology; Pruritic, purple, papules 2020-02-04 · COMMENT: The histologic sections show squamous mucosa with increased intraepithelial lymphocytes with a prominent lichenoid pattern of injury with numerous apoptotic keratinocytes (“Civatte bodies”). Se hela listan på en.wikipedia.org Interface dermatitis includes diseases in which the primary pathology involves the dermo-epidermal junction. The salient histological findings include basal cell vacuolization, apoptotic keratinocytes (colloid or Civatte bodies), and obscuring of the dermo-epidermal junction by inflammatory cells.

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.
