Deep blue colour of hypostasis is seen in death due to poisoning by?
A) Potassium cyanide
B) Phosphorus
C) Aniline dyes
D) Carbon monoxide

As far as I looked, in text books by Dr.Apoorva Nandy, Dr.Narayana Reddy and Dr.Parikh,

Asphyxia - Blue
Cyanide - Bright Pink or Red
Phosphurus - Dark Brown
Aniline Dyes - Red Brown
Nitrites - Red Brown
CO - Cherry Red

It is easy to understand why blood is Red in Cyanide and Carbonm Monoxide inspite of them being "asphyxiants"

In both these cases oxygen is not used as they interfer at the level of respiratory chain

Discussion
Hypostasis is discolouration of the skin and organs after death due to accumulation of fluid blood in the dependent parts of the body. Post mortem lividity is also called
 Post mortem hypostasis
 Livor Mortis
 Vivices
 Suggilation
 Postmortem Staining
Post mortem hypostasis is Blue colour in deaths due to Asphyxia and Poisoning with Aniline
Explanation
One book gives that Post mortem hypostasis is blue coulour in Poisoning with Aniline. So we are going for Aniline as the answer, though few other books give that Aniline produces Brown Colour. And all INDIAN books agree with the postmortem hypostasis in other options. (Let us limit our self to Indian authors, though one foreign book says that the colour is blue in KCN poisoning, but remember this fact if you see this question next time with aniline not in any of the choices, but KCN is there in the list. )
Comments
The colour normally is
 at first Bluish pink,
 then Bluish purple
The colour of the lividity changes in Poisoning due to various agents are
 Pink Cyanide
 Bright Cherry Red Carbon monoxide
 Color of the skin is bright cherry-red if saturation of carbon monoxide in the blood is > 30%.
 If < 20%, then such a coloration is not visible
 Blue Aniline (As per Apurva Nandy)
 Reddish Brown Aniline, Nitrites
 Chocholate Brown Potassium Chlorate
 Dark Brown Phosphorus
 Greyish Brown Septic abortin caused by C. welchii
 Black Opiates
 Bluish green Hydrogen Sulphide
Tips
Contact palor is a phenomenon which refers to the paleness of the areas that are in direct contact with the surface. This is similar to Contact Flattening in Rigor Mortis.

Hi!! Dr.Bruno
I am really impressed by the amount of research u put and try to find references for each and every question
This Q regarding Deep Blue hypostasis is a tough one,with all respect to Dr.Nandy I must Qoute Dr.V V Pillay's mail written to me on 6th dec 2004 according to him
"Dear Dr. Sumit Seth,
Thank you for the kind sentiments expressed in your message.
Regarding PM lividity of the poisons mentioned in your mail, I am providing you the information available with me:
a) Phosphorus: Brown
b) Aniline: Brownish red, or dark brown
c) Pot. Cyanide: Bright (brick) red, or rarely dark bluish
d)CO poisoning: Cherry red (pink)
I have no information on any poison that produces "deep blue" discolouration, though this may be possible in cases where intense cyanosis was present. Cyanide occasionally produces bluish colour for this reason.Sincerely,
Dr.V.V.Pillay
Chief
Analytical Toxicology
Amrita Inst of Med Sciences
Cochin 26Ph: 0484-2804852 (direct dialling)

Thus i will recommmend all student to go for KCN in c/o Deep blue color Hypostasis
With Regards
Dr.Sumit Seth

Agreed...... I will change it in the next edition of the book.... The RxPG AIPG 2001 to 2005 book to be released in a couple of months (with AIPG 2005)

By the way, Dr.Sumit, your book on Forensic Medicine is excellent........
