shadow cell

A pale, lightly eosinophilic (pink) cell, often devoid of a nucleus
Dermatology A pale pink, anuclear keratinocyte seen in skin adnexal tumours—e.g., pilomatricomas—cutaneous mixed tumours, proliferating trichilemmal tumourus, rare basal cell carcinomas, alopecia areata, onychomycosis, epidermoid cysts in Gardner syndrome, and dermoid cysts
Haematology See Ghost cell
Pathology A descriptive term that may be used for any cell that doesn’t stain—i.e., is negative by the immunoperoxidase stain—in tissues or in cytologic specimens, serving as vague tissue landmarks

shadow cell

one that appears in a section only as an outline. Called also ghost cell.

Worcester, where it shares the stage with Griffon, Tunnel Drill, Let Down and Shadow Cell.
Early lesions tend to become cystic whereas older become solid with prominent shadow cell component, keratin debris, multinucleated giant cells and dystrophic calcification with the incidence ranging from 69% to 85% (8,10,11,12).
3) These tumors have more mitotic figures and fewer shadow cells when compared with nonproliferative pilomatricomas, and they are fast-growing, large lesions.
Pilomatricomas are composed of two types of cells namely basophilic and shadow cells with areas of calcification (Fig.
If fine-needle aspiration is performed, the diagnosis of PM may be made only if all major components of PM are present in the aspirate, including calcium deposition, basaloid cells and keratinized ghost or shadow cells.
There is a study suggesting that apoptosis is the main mechanism leading to the development of the dead shadow cells and is most probably responsible for the biological behaviour of pilomatricoma.
Finding follicular bulbs, papillary mesenchymal bodies, trichohyalin granules, hair shafts, shadow cells, and focal CD34 staining in adjacent tumor stromal cells all favor benign entities.
FNA of the lesion commonly reveals basaloid cells, squamous cells, anucleate squames, shadow cells, foreign-body giant cells, polymorphs, and calcification in variable frequencies.
Tumors are well-circumscribed, dermal to subcutaneous nodules composed of several components, including basaloid proliferation, shadow cells, dystrophic calcifications, and foreign-body giant-cell reactions (figure 1).
There were squamoid cells with adjacent shadow cells.
Several nests of shadow cells, wet keratin and keratin pearls are present [Figure 3].
