In histology, bodies are broadly classified into the following categories: 1. Naturally occurring body - a mass of matter found anatomically or physiologically in organs and tissues 2. Foreign body - a mass or entity that has been introduced from an external source. In other words, any mass found in an organ or tissue in which it does not [Histologic and immunofluorescence microscopy phenomena of keratin (Civatte) bodies of PUVA treated cutaneous lichen ruber planus].

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.

The salient histological findings include basal cell vacuolization, apoptotic keratinocytes (colloid or Civatte bodies), and obscuring of the dermo-epidermal junction by inflammatory cells. The dermal papillae between the elongated rete ridges are frequently dome shaped. Necrotic keratinocytes can be observed in the basal layer of the epidermis and at the dermal-epidermal junction. Eosinophilic remnants of anucleate apoptotic basal cells may also be found in the dermis and are referred to as “colloid or civatte bodies”. In histology, bodies are broadly classified into the following categories: 1.

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. [Histologic and immunofluorescence microscopy phenomena of keratin (Civatte) bodies of PUVA treated cutaneous lichen ruber planus]. [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. How is poikiloderma of Civatte diagnosed?

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. 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.
