  Introduction Top


Chickenpox is a highly contagious and relatively common viral infection of children. The symptoms may be severe in adults, neonates and immunologically compromised patients. [1] A case of chickenpox induced purpura fulminans associated with gangrene of the digits in an infant is reported here for its rarity.


  Case Report Top


A 3 month female baby was admitted primarily for fever of 8 days duration. Child's antenatal and neonatal history was uneventful. Child had history of contact with chickenpox affected aunty 2 weeks ago. Child developed vesicular eruption surrounded by erythematous halo compatible with chickenpox on 2 nd day of admission. Three days after admission bluish discoloration and oedema of lower limbs were noticed, more evident and severe on the right foot. In the next 2 hours cyanosis and oedema of upper limb digits was also noticed. The oedematous areas were tender and turned blackish later. Child also developed ecchymotic rash over extremities, gluteal region and trunk. Systemic examination did not reveal any abnormalities except tachycardia. Over the next 12 hours the left hand and left foot gradually resumed normal appearance, but the right lower extremity and right upper extremity digits remained grossly swollen. The changes persisted and all 5 toes of the right foot [Figure - 1] and tip of digits of right hand became gangrenous.

Haematological investigations done on the day child developed oedema and cyanosis with ecchymotic rash showed thrombocytopenia (1,00,000 cells/mm 3), prolonged clotting time and prolonged prothrombin time. WBC count was 10600 cells/mm 3 with normal differential count. Cytodiagnostic test of vesicular base revealed typical multinucleated giant cells suggestive of viral aetiology. Fresh blood transfusion and IV administration of acyclovir (5mg/kg) at 8 hourly intervals for 5 days healed chickenpox lesions and arrested the fatal progression of the disease.

The clinical findings in the present case were those of purpura fulminans following chickenpox. This condition has been reviewed by Horder. [2] Following typical chickenpox, symmetrical haemorrhagic lesions appear on the lower limbs and the process may combine to produce extensive necrosis of the skin and other tissues. Disseminated intravascular coagulation occurs resulting in low prothrombin and reduced amounts of V,VII,VIII and IX and the production of a thrombotic purpura. In the present case laboratory tests for coagulation profile gave indication of a generalized consumptive coagulopathy.

Wishik and Bullowa [3] catalogued the complications seen in 2534 cases of chickenpox between 1929 and 1933. One of these was a 3-year-old boy with mild varicella who developed discoloration and eventually gangrene of the digits. Venous thrombosis with bilateral digital gangrene in the absence of a generalized consumptive coagulopathy has been described following chickenpox in a 6 year-old child. [4]

Occasionally HSV infection presents as varicella like eruption (disseminated HSV) that can cause confusion in diagnosis. But, a history of genital herpes in the mother, the presence of keratoconjunctivitis and typical herpetic oral lesions in HSV infections may be clinically helpful. [5] Present case with definite history of contact with chickenpox patient and with absence of any clinical involvement of eye or oral mucous membrane fits into varicella infection only.

To conclude, present case of chickenpox with severe complications like purpura fulminans and digital gangrene appears to be the youngest reported.
