Thin strands of atypical epidermal cells penetrate the basement membrane to reach upper dermis.
Atypical epidermal cells with large hyperchromatic nuclei show complete disorderly arrangement of cells.
Epidermis becomes acanthotic with elongation & thickening of rete ridges, with thin strands of intertwining papillae.
Individual cell keratinization leads to formation of large, round dyskeratotic cell with hyperchromatic nucleus & eosinophilic cytoplasm.

Follicular scars are typical feature of late phase.
Early phase may show trichomalacia and pigment cast.

Untrue statement related to these cells seen on tzank smear is:
Cytology is very helpful in detecting Leishman Donovan ( LD) in early , untreated patient of leishmaniasis.
LD bodies Appear as light blue ,ellipsoid Bodies, 2 -4 mm long with an eccentric nucleus and a smaller kinetosome at the opposite pole
Virchow’s cell are typical macrophages containing leishmania.
Cytology may not be useful in chronic forms of leishmaniasis.
This appearance is seen in all except:
Lichen nitidus
Lichen scrofulosorum
Juvenile xanthogranuloma
Lichenoid eruptive histocytoma
This histological appearance is not related to which drug ?

Nifedipine
Captopril
Phenobarbital
All statements about touton giant cells are true except ?
Central ring of nuclei is found.
Peripheral densely pink cytoplasm with abundant lipid granules .
Cells react with alpha 1 antitrypsin & chymotrypsin indicates their histiocytic origin
Dermatofibroma can have these cells.
Incorrect statement about foreign body giant cells is?
Endogenous triggers can not lead to their formation.
Nuclei scattered irregularly
Can be seen in BT hansens
Larger in size than langhans giant cells
Elastic fibers are demonstrated by which specific stain ?
Von Kossa stain – black
Van gieson stain – red
Verhoeff’s stain – Black
De galantha stain – blue
Which of the following type of cutaneous tuberculosis uncommonly demonstrates caseation necrosis on histopathology ?
Tuberculosis verrucosa cutis
Scrofuloderma
Tuberculosis gumma
Lupus Vulgaris
Tadpole appearance of epitheial strands is seen in all except ?
Desmoplastic trichoepithelioma
Eccrine poroma.
Sclerosing basal cell carcinoma
Syringoma
This appearance is typical for which disease ?
Pemphigus vulgaris
Pemphigus foliaceous
Subcorneal Pustular dermatosis
Pemphigoid gestationalis
Incorrect statement about Michel’s medium is ?
This transport medium contains equal molar concentrations of ammonium sulfate in Nethylmaleimide, potassium citrate buffer, magnesium sulfate.
It preserves immunoantigenicity of the specimen by its ability to precipitate macromolecules while inhibiting proteolytic enzymes.
Immunoreactants may be demonstrable by DIF even at 6 months, indicating the reliability of this medium.
Biopsy kept in michel’s medium should reach laboratory within 1-2 weeks for best results.
