This is the very basic lecture of dermatology every resident needs. Thank you for your continuous guidance.

[@sabhderma]

Glad it was helpful! I agree. If we simplify concepts and explain, it becomes a lot easier to grasp dermatology. 😊😊

[@Hamradilli]

Please do continue the series of dermatopathology! Never understood it better

[@sabhderma]

I am glad you found this useful. Yes, we will make videos on dermatopathology from time to time 😊😊

[@drreenavlogs8576]

Please continue videos series

[@sabhderma]

Surely

[@tushar2919]

Alternating ortho and parakeratosis- pityriasis rubra pilaris

[@sabhderma]

Cool! Where? Add a time stamp on the video so that I may know what you are referring to.

[@CA-and-doctor-couple]

Sir aren’t keratohyaline granules and Orlando bodies different? @14:56

[@sabhderma]

Yes, odland bodies mainly have lipids to form the cholesterol layers, while keratohyaline has proteins and enzymes for keratinization.

[@swatijoshi2318]

Is it plasma cell sir? In Dyskeratosis section @ 58:10

[@sabhderma]

That's a nice try. but look at the cytoplasm color and the shape of the nucleus. It's not a plasma cell. Any other answers?

[@roshanisk5189]

Eoisinophil sir?

[@swatijoshi2318]

​@@sabhdermaits a cell with eosinophilic homogenous cytoplasm and peripheral slipper shaped nuclei....I am not in favour of eosinophil. Please explain sir.

[@priyankasingh-dr6cj]

PRP & ILVEN

[@sabhderma]

Absolutely! 😁😁

[@adapalaindraja3797]

Eosinophil sir?

[@sabhderma]

Hi, what about them? Are you referring to a certain part of the video? If yes, kindly put time stamps so that I will know. 😊

[@AvaniTalati]

Pityriasis rubra pilaris( checkerboard pattern)

[@sabhderma]

Any particular time stamp you want to mention?

[@vikaspurushottam8542]

Psoriasis m dono hote h ortho and parakeratosis

[@vikaspurushottam8542]

Eosinophils cell

[@sabhderma]

Para keratosis hoga because it's a scaly disease. In areas of just thickening of s corneum, you will see ortho keratosis. So you are right in your statement ☺️

[@sabhderma]

Unke baare me kya?
